Should I open or buy a Subway franchise in 2027?

What a Subway franchise actually is in 2027 and why the structure matters

A Subway franchise is a license to operate a sandwich quick-service restaurant under Subway's marks, using its supply chain, menu, and national marketing, in exchange for an initial franchise fee and a permanent share of gross sales. The economics live or die on three numbers most first-time buyers underweight: the royalty rate, the advertising fund contribution, and the fact that both are charged on top-line sales, not profit.

The initial franchise fee sits at $15,000, which is low relative to most restaurant brands — that low entry fee is the single biggest reason Subway attracts undercapitalized buyers. Total initial investment per the FDD Item 7 range runs $199,135 to $536,745, depending on venue type, build-out condition, equipment package, and market. Non-traditional locations (a counter inside a hospital cafeteria, a university student union, a travel plaza, a military base exchange, a convenience-store co-brand) land toward the low end because the landlord often delivers usable infrastructure. A ground-up or gut-renovation inline strip-center store lands toward the high end.

The ongoing cost structure is where the business changes character. Royalty is 8.0% of gross sales. The national advertising fund is 4.5% of gross sales. Combined, that is 12.5% of every dollar that crosses the register, removed before you pay for food, labor, or rent. Historically Subway ran a materially lower royalty; the increase under Roark Capital ownership permanently compressed store-level free cash flow for every operator in the system. If you built a financial model using a franchisee's decade-old numbers, that model is wrong by hundreds of basis points at the operating-income line.

The other structural fact worth internalizing before you spend a dollar: Subway does not publish an Item 19 financial performance representation. Most major restaurant franchisors do. Item 19 is the section of a Franchise Disclosure Document where the franchisor discloses actual system sales, unit volume distributions, and sometimes cost lines. Without it, the franchisor is legally prohibited from making financial performance claims to you, and you are left assembling your own picture from third-party category research and from calling existing operators. That disclosure gap is not evidence of fraud, but it is a real information asymmetry, and it shifts a large amount of diligence labor onto the buyer.

Why does any of this matter to someone reading a RevOps library? Because franchise buying is a revenue-operations problem wearing an apron. You are underwriting a fixed cost base against a forecasted revenue line, in a territory with measurable competitive density, with a contractual take rate off the top. The discipline is identical to modeling a sales territory: validate the demand, validate the capacity, validate the take rate, and refuse to close when the unit economics only work under optimistic assumptions.

The system-level context also matters. The U.S. Subway footprint has contracted for roughly a decade, from a peak above 27,000 locations to a base under 19,000, with net closures every single year of that stretch — including several hundred more in the most recent reported year. A shrinking system is not automatically a bad investment; it can mean the weakest locations are being culled and the survivors get more of the trade area. But it does mean you cannot assume the brand tailwind that existed when Subway was the fastest-growing restaurant chain in America. You have to underwrite the specific store, in the specific trade area, with the specific lease.

The step-by-step process for evaluating and closing a Subway deal

Treat this as a gated ninety-day process, not a shopping trip. Every gate has a written pass/fail threshold you set before you see the numbers, because setting thresholds after you fall in love with a location is how people talk themselves into bad leases.

Days 1–10: get and read the FDD. Request the current Franchise Disclosure Document directly from Subway's franchise development team or through the broker representing a resale. Federal rules require you receive it at least fourteen days before signing anything or paying money. Read Items 5 (initial fees), 6 (all other fees — technology, POS, transfer, renewal, local advertising minimums, audit fees), 7 (estimated initial investment), 17 (renewal, termination, transfer, dispute resolution), 20 (outlet counts and franchisee contact lists), and 21 (franchisor financial statements). Item 6 is where the fees people forget live; the headline 12.5% is not the whole ongoing cost.

Days 11–25: call twenty operators. Item 20 includes a roster of current franchisees with contact information, plus a list of franchisees who left the system in the prior year. That roster is your substitute for the missing Item 19. Call at least twenty current operators — some in your target market, some in comparable markets elsewhere — and ask a consistent script: trailing-twelve gross sales, food and paper as a percent of sales, labor as a percent of sales, total occupancy as a percent of sales, cash flow after debt service, hours the owner personally works, and the one question that reveals the most, *"knowing what you know now, would you buy this store again?"* Also call several of the departed franchisees. People who exited will tell you things current operators won't.

Days 26–40: validate the trade area. Pull daytime population, traffic counts, and competitive density for a 1.5-mile ring. You want meaningful daytime population — office workers, students, hospital staff, industrial shift workers — because Subway's business skews heavily to lunch. Count every competing sandwich concept in the ring: Jersey Mike's, Jimmy John's, Firehouse Subs, Potbelly, Capriotti's, plus grocery deli counters and the local independent that has been there thirty years. Also count existing Subway units, because the most common self-inflicted wound in this system is cannibalization from a nearby unit that the franchisor approved years ago. Drive the site three separate times: weekday lunch rush, weekday evening, and Saturday midday.

Days 41–55: line up financing. SBA 7(a) is the standard instrument for restaurant franchise acquisition. Get quotes from at least three SBA-preferred lenders that actively lend on food service, not just your local bank. Compare not only rate but amortization term, prepayment terms, required equity injection, whether the loan requires a life-insurance assignment, and the scope of the personal guaranty. Model debt service against a conservative revenue case, not the seller's best year.

Days 56–70: LOI and lease. For a resale, the letter of intent should be structured on a multiple of seller's discretionary earnings, with the purchase price contingent on verification against tax returns and raw point-of-sale exports. For a new build, negotiate tenant-improvement allowance and free-rent months hard — those two terms move your break-even date more than almost anything else you control. Cap or limit your personal guaranty on the lease if the landlord will accept a burn-down after a set number of months of on-time payment.

Days 71–85: franchise attorney review. Hire an attorney who specializes in franchise law, not a generalist. They will read the FDD, the franchise agreement, the transfer documents, and the lease as an integrated package and tell you which obligations survive a sale, what happens at renewal, what the remodel obligation looks like, and how disputes are resolved.

Days 86–90: go or no-go against your written thresholds. No negotiating with yourself.

Costs, timelines, and the ranges a realistic model should use

Build your model bottom-up from a percent-of-sales P&L, then stress it. The categories below are the ones that actually move the answer.

Food and paper typically runs in the low-thirties as a percent of sales for a sub shop. Subway's menu is protein-and-produce heavy with relatively low-cost bread, which helps, but promotional pricing hurts. Years of aggressive discounting — footlong price promotions, buy-one-get-one offers, app-driven coupons — trained a meaningful share of the customer base to buy only on promotion. When a large share of your mix is discounted, your effective food cost percentage rises even though your invoice costs did not change.

Labor is the swing factor and it is where the "should I buy this" answer usually gets decided. An owner who personally works the line fifty to sixty hours a week can hold labor in the mid-twenties as a percent of sales. An absentee owner who hires a general manager on day one is adding a salary plus payroll taxes plus benefits onto a store whose gross profit dollars may not support it. In a state with a fast-food-specific minimum wage — California's fast-food minimum is the most consequential — a store doing roughly average volume can mathematically lose the entire operating margin to the labor line. Before you buy in a high-wage state, run the labor line at the *legally mandated* rate plus scheduled future increases, not at what the seller paid three years ago.

Occupancy — base rent, common-area maintenance, property taxes, insurance, and utilities — commonly lands in the low double digits as a percent of sales for inline retail. This is the number that most cleanly separates a viable Subway from a doomed one. If you own the building, or your family trust owns it, or you have a non-traditional venue where the host institution charges a modest commission instead of market rent, the entire investment thesis changes. If you are signing a market-rate strip-center lease at a rent that only works at above-average volume, you are betting the store on a sales number you have not yet proven.

Royalty and advertising are fixed at 12.5% of gross sales and are not negotiable for a single-unit operator. Model them as an unavoidable line.

Other operating expenses — credit-card processing, third-party delivery commissions, repairs, small wares, uniforms, local marketing, POS and technology fees, accounting — add up to a mid-single-digit percentage. Third-party delivery deserves special attention: marketplace commissions on delivery orders are large enough that unmenued delivery pricing can turn incremental orders into negative-margin orders. If delivery is a meaningful share of your mix, price the delivery menu separately.

What's left. Stack those percentages and a typical store at roughly average volume produces a mid-single-digit to low-double-digit operating margin before debt service and before owner compensation. On roughly $490,000 of sales, that is tens of thousands of dollars, not hundreds. After SBA debt service on a several-hundred-thousand-dollar acquisition or build loan, the residual owner cash flow in year one is modest — the kind of number where a single bad quarter, an equipment failure, or a rent escalation flips it negative.

Timelines. Site selection and lease negotiation for a new build commonly runs three to six months. Permitting and build-out adds two to five months depending on jurisdiction and whether you inherited a usable restaurant space. Training and pre-opening runs several weeks. A resale can close in sixty to ninety days if the franchisor's transfer approval and the landlord's lease assignment cooperate, and both of those can add weeks you did not plan for. Simple payback on invested capital in this system, at average volume, is measured in years, not months — plan for a multi-year horizon and reserve accordingly.

Working capital. Budget enough unencumbered cash after closing to fund six to nine months of operating shortfall. New restaurants ramp; resales often dip during the ownership transition as crew turns over. Being forced to draw on a credit card to make payroll in month four is the failure pattern, not the exception.

Where buyers get this wrong

Anchoring on the $15,000 franchise fee. The fee is the cheapest part of the deal and it is irrelevant to whether the business works. What matters is total invested capital, the lease, and the 12.5% off the top. Cheap entry is precisely what draws in buyers who lack the reserve to survive the ramp.

Buying a declining store at a stable-store multiple. If trailing sales have fallen for three consecutive years, you are not buying an earnings stream, you are buying a turnaround — and you should pay a turnaround price. Demand three years of tax returns and raw POS exports, not a seller-prepared spreadsheet. Compare the returns to the POS data. Discrepancies are diagnostic.

Signing a long personal guaranty on a bad location. A ten-year triple-net lease with a full personal guaranty is the single largest wealth-destruction mechanism in small-franchise investing, because it survives the closure of the business. If the store fails in year three, the guaranty on the remaining seven years does not disappear. Negotiate a guaranty cap, a burn-down provision, or a shorter initial term with options.

Underwriting labor at the owner's own free hours forever. Many models pencil only because the owner works sixty hours unpaid. That's acceptable as a temporary strategy for the first eighteen to twenty-four months while you build volume. It is not a business — it is a job with capital at risk. Ask honestly whether the store still clears a return after you pay a real manager a real wage, because eventually you will need one.

Ignoring competitive density. A store two miles from a Jersey Mike's, a Jimmy John's, and a Firehouse Subs is fighting three better-funded, higher-average-ticket concepts for the same lunch daypart. Those brands have taken share in the sub category for years. Being the cheapest option in a category where consumers have traded up is a difficult position to defend.

Treating cannibalization as the franchisor's problem. Confirm in writing what territorial protection, if any, the franchise agreement grants. In a system with historically dense unit placement, an approved new unit nearby can materially damage your sales, and your remedy may be limited.

Skipping the departed-franchisee calls. Item 20 lists franchisees who left the system. Those calls are uncomfortable and they are the highest-signal diligence you will do.

Modeling only the base case. Build three cases: base, a downside where sales come in fifteen percent under plan, and a stress case with a minimum-wage increase plus a rent escalation. If the downside case cannot service debt, the deal is too tight regardless of how good the base case looks.

Decision framework: when to open, when to buy, and when to walk

There are really only four viable postures, and the right one is determined by what you control — real estate, labor, and volume.

Open a new unit only when you have a genuinely under-served trade area *and* a favorable occupancy structure. In practice that almost always means a non-traditional venue: a hospital, a university campus, a military installation, a travel plaza, an airport concourse, or a convenience-store co-brand. In those settings you get captive daytime traffic, shorter operating hours, lower build cost because the host provides infrastructure, and often a commission-on-sales arrangement instead of a fixed market rent — which converts your largest fixed cost into a variable one. That single change materially de-risks the investment.

Buy an existing unit when you can verify stable-to-rising sales against tax returns, the lease has meaningful remaining term with reasonable escalations, and you can negotiate the price to a multiple that leaves room for error. A seasoned crew, an established customer base, and a known sales history are worth real money compared with the guesswork of a new build. Pay for the *proven* earnings, not the seller's story about what the store could do.

Buy distressed when you have operating experience and the seller is tired. A burned-out owner selling below the normal range, in a location with acceptable rent, is the highest-return version of this deal — you buy cheap, apply real operating attention, and reinvest the discount into remodel and local marketing. This posture requires that you can actually run restaurants; it is not a first-timer play.

Walk away when the store cannot clear a conservative debt-service coverage threshold, the lease is short or the guaranty is unlimited, operator interviews skew negative, or your labor line is legally rising faster than your ability to raise price. Walking away costs you diligence expense. Closing on a bad deal costs you years.

If your goal is restaurant ownership generally rather than Subway specifically, the honest comparison is worth running: several competing sub franchises publish an Item 19, carry a lower combined royalty-plus-ad load, and operate at materially higher average unit volumes. Higher investment, higher revenue, published numbers, positive brand momentum. Run all of them through the same gates in the same spreadsheet and let the model choose. Conversely, an independent sub shop in a college or hospital district eliminates the 12.5% drag entirely, at the cost of the brand, the supply chain, and the national marketing — a real trade, not obviously a bad one for an experienced operator.

Related questions

How much cash do I actually need on hand beyond the purchase price?

Plan for six to nine months of operating shortfall in unencumbered cash after closing, on top of your equity injection and closing costs. New stores ramp slowly and resales often dip during the crew transition. Running out of working capital in month four is the most common failure.

Does Subway really not publish an Item 19?

Correct — Subway has not included a financial performance representation in its FDD, which is unusual for a system of its size. That means the franchisor cannot legally make earnings claims to you, and your diligence burden shifts almost entirely to Item 20 operator interviews and third-party category data.

Is a non-traditional location genuinely better, or is that just sales talk?

Genuinely better, for structural reasons: lower build cost, captive daytime traffic, shorter hours, and frequently a commission-on-sales rent structure instead of fixed market rent. That converts your biggest fixed cost into a variable one, which is the single most protective change you can make to the model.

What multiple should I pay for an existing store?

Price against verified seller's discretionary earnings from tax returns, and stay conservative — under roughly two times for a stable store, lower for one with a declining trend or a short lease. Never pay a stable-store multiple for a turnaround, and never price off a seller-prepared spreadsheet.

How does the franchisor's own profitability relate to mine?

It doesn't, directly. The franchisor earns on gross sales and system size; you earn on what's left after food, labor, and rent. A profitable franchisor and a squeezed franchisee base can and do coexist. Underwrite your store, not the parent company's press releases.

FAQ

Is a Subway franchise still profitable in 2027?

It can be, but the margin is thin and highly conditional. At roughly average unit volume, with 12.5% going to royalty and advertising off the top, a well-run owner-operated store produces a modest operating margin before debt service. Profitability improves sharply if you own the real estate, operate a non-traditional venue, or hold multiple units that share labor and management. It deteriorates sharply with a market-rate lease, an absentee ownership structure, or a state-mandated fast-food wage floor.

What does it cost in total to open a new Subway?

The FDD Item 7 range is roughly $199,135 to $536,745 in total initial investment, inclusive of the $15,000 initial franchise fee. The low end reflects non-traditional venues and spaces delivered with usable infrastructure; the high end reflects full inline build-outs in expensive construction markets. Add unencumbered working capital on top — the Item 7 range is not a substitute for a reserve.

Why has Subway been closing so many U.S. stores?

The system peaked above 27,000 U.S. units and has contracted every year for about a decade, to a base under 19,000. The drivers are unit density that made stores compete with each other, competitive share loss to higher-ticket fast-casual sub brands, thin store-level margins that made marginal units unsustainable, and a franchisor strategy under new ownership that closes underperformers rather than backfilling them.

Should I buy an existing store instead of building new?

Usually yes, for a first-time owner. A resale gives you a verifiable sales history, an existing crew, and a known customer base — three things a new build asks you to guess at. Insist on three years of tax returns and raw POS exports, verify the lease's remaining term and escalation schedule, and price off proven earnings. The exception is a strong non-traditional venue, where a new unit's occupancy advantage can outweigh the resale's certainty.

How long until I break even and recover my investment?

At roughly average volume, plan for a multi-year payback measured in years rather than months. It shortens meaningfully if you eliminate or reduce the occupancy line, work the store yourself during the ramp, and hold labor discipline. It lengthens or never arrives if you buy a declining store at a full multiple or carry a market-rate lease that only works at above-average sales.

What's the single biggest mistake first-time buyers make?

Signing a long lease with an unlimited personal guaranty on a location they have not validated. The store can close; the guaranty does not. Every other mistake on this list is recoverable with time and effort. That one follows you for the remaining term of the lease, which is why lease negotiation deserves as much attention as the purchase price itself.
