The Core Formula: TI Differential Divided by Annual Rent Savings

The math is simple, but you have to use the right inputs. The break-even formula is:

Break-Even Years = (TI Allowance A – TI Allowance B) / (Annual Rent B – Annual Rent A)

Here's a real-world example. Option A: $60 per square foot TI with $30 per square foot annual rent. Option B: $40 per square foot TI with $27 per square foot annual rent. The TI difference is $20 per square foot. The annual rent savings is $3 per square foot. Break-even = $20 / $3 = 6.67 years.

• If your lease term is 5 years, you never reach break-even — the higher TI was better.
• If your lease term is 10 years, you break even at year 6.67 and then save money for the remaining 3.33 years.
• If you have renewal options, count them in the term if you're confident you'll stay.

Critical nuance: This formula assumes you actually *use* the full TI allowance. If your buildout only costs $35 per square foot, taking the $60 allowance means you're leaving $25 per square foot on the table — and that changes the math entirely. Always calculate based on actual construction cost, not the allowance cap.

When Higher TI Wins: Short-Term Leases and Cash-Flow Constraints

A higher TI allowance is the right move when your lease term is short (3–5 years) or your business needs cash for inventory, equipment, or payroll. Here's why:

• Short-term leases (3–5 years) rarely let you recoup the rent savings because the break-even point typically falls in year 5–8. Taking $50 per square foot in TI on a 5-year lease means you get your buildout paid for upfront, and you don't care about the slightly higher rent because you're gone before it hurts.
• Startups and growing companies should prioritize TI because capital preservation matters more than long-term rent optimization. A $100,000 TI check from the landlord means you don't burn your own cash on drywall and flooring.
• High-growth businesses that expect to outgrow the space should take the highest TI they can negotiate. You'll be expanding or relocating in 3–4 years anyway — the rent premium never becomes a problem.
• Triple Net (NNN) leases complicate this: if you're paying your own operating expenses, the base rent difference is smaller relative to total occupancy cost. A lower base rent in a NNN lease matters less than in a gross lease, so TI often wins in NNN deals.

When Lower Rent Wins: Long-Term Occupancy and Credit Tenants

Lower base rent dominates when you're signing a 10+ year lease or you're a credit tenant with leverage. The math is relentless: every dollar you shave off annual rent compounds over a decade.

• Long-term leases (10–15 years) almost always favor lower rent. Using the example above, a $3 per square foot annual savings on a 50,000 square foot space over 15 years equals $2.25 million in total savings — far more than any TI differential.
• Credit tenants (national retailers, banks, medical groups) can often negotiate both high TI *and* low rent because landlords want their signature. But if you have to choose, take the rent reduction — it's recurring and improves your profit and loss statement every month.
• Inflation protection: Lower base rent protects you against operating expense escalation in NNN leases. If your base is $22 instead of $25, your total occupancy cost stays lower even as taxes and insurance rise.
• Exit strategy: If you sublease or assign the lease, a below-market rent is an asset. Future tenants will pay a premium for your low rent. High TI doesn't transfer — it's already built into the walls.

The Time Value of Money: Discounting Future Rent Savings

The simple break-even formula ignores the time value of money — a dollar today is worth more than a dollar tomorrow. If you have a cost of capital (say, 10% for your business), you need to discount future rent savings to present value.

How to do it: Use a Net Present Value (NPV) calculation. Discount each year's rent savings back to today using your discount rate. Compare that to the TI differential you give up.

Example: $3 per square foot annual savings for 10 years at a 10% discount rate has a present value of about $18.43 per square foot. If you gave up $20 per square foot in TI, the NPV says the lower rent is actually *worse* over 10 years when you account for the time value of money. That flips the simple break-even result.

When this matters most:

• High-growth companies with a high cost of capital (venture-backed startups) should heavily discount future savings — TI wins more often.
• Stable businesses with low borrowing costs (like a medical practice with a 5% loan) can afford to wait for long-term rent savings.
• Inflation assumptions matter too: if you expect 3% annual rent escalations, the gap between two rent options widens over time, making lower base rent even more valuable.

Quick rule: If your discount rate is above 12%, take the TI. If it's below 8%, take the lower rent. Between 8–12%, run the full NPV.

Negotiation Strategy: How to Use the Break-Even Against the Landlord

Once you know your break-even, you can negotiate smarter. Landlords often present TI and rent as separate line items, but they're two sides of the same coin — every dollar of TI is amortized into the rent over the lease term.

Three negotiation plays:

1. The TI-to-Rent conversion: Ask the landlord, "What's the rent increase per dollar of TI?" A typical conversion is $0.10–$0.15 in annual rent per $1.00 of TI over a 10-year lease. If they're charging you $0.20, you're getting a bad deal — push back.
2. The split-the-difference: If your break-even is 7 years and you're signing a 7-year lease, propose a midpoint — take half the TI and half the rent savings. This hedges your risk if you leave early or stay longer.
3. The TI cap with rent step-downs: Negotiate a high TI allowance but with rent reductions in later years. For example, $60 TI with rent at $30 for years 1–5, then $27 for years 6–10. This gives you upfront cash and long-term savings.

Red flags:

• A landlord who refuses to show you their TI amortization schedule is hiding something. Demand it.
• Watch for TI clawback clauses — some leases require you to repay unamortized TI if you leave early. That changes your break-even dramatically.
• Buildout ownership: If the TI goes into landlord-owned improvements, you're essentially giving them free capital. Negotiate that improvements you fund with TI are your property for the lease term.

Common Mistakes and How to Avoid Them

Tenants make predictable errors when calculating TI vs. rent break-even. Here are the five biggest traps and how to sidestep them:

1. Ignoring rent escalations: Most leases have annual rent increases (2–4% per year). If Option A has $30 rent with 3% escalations and Option B has $27 rent with 3% escalations, the gap widens over time. Use a year-by-year rent schedule, not a flat average.
2. Forgetting operating expenses in NNN leases: In a NNN lease, the base rent is only part of your cost. If operating expenses are $10 per square foot, a $3 base rent difference becomes a smaller percentage of your total $40 per square foot occupancy cost. This makes TI relatively more attractive.
3. Assuming you'll use all the TI: If your buildout costs $40 per square foot but the landlord offers $60, you don't get to pocket the extra $20. It's use-it-or-lose-it. Always calculate break-even based on actual construction costs, not the allowance cap.
4. Neglecting renewal options: A 5-year lease with two 5-year renewal options is effectively a 15-year commitment if you're likely to stay. Count renewal periods if you have high certainty (e.g., a medical practice with a loyal patient base).
5. Overlooking TI repayment clauses: Some leases require you to repay unamortized TI if you terminate early. If you take $60 TI on a 10-year lease and leave in year 6, you might owe $24 per square foot. That changes the break-even calculation entirely — factor it in before signing.

Pro tip: Build a simple three-scenario model — best case (you stay full term), base case (you leave at break-even), and worst case (you leave in year 3). The decision that works in two out of three scenarios is your safest bet.

FAQ

What is a typical TI allowance per square foot? A typical TI allowance ranges from $20 to $80 per square foot depending on market, building class, and lease term. Class A office space in major metros often sees $50–$80, while industrial space may be $10–$30.

How does rent-free period factor into the break-even? Rent-free months effectively lower your average rent over the lease term. If you get 6 months free on a 5-year lease, your effective rent drops by 10% — that changes the break-even math. Always calculate your effective rent including free rent, not the face rent.

Can I negotiate both higher TI and lower rent? Yes, especially if you're a credit tenant or in a soft market. Landlords with high vacancy may concede both to get a signature. But you'll usually have to trade one for the other — know which matters more for your business.

What if my buildout costs less than the TI allowance? You typically cannot pocket the difference. Some landlords allow you to use unused TI for future improvements or furniture, but most require you to spend it on the space. Negotiate a "TI carry-forward" clause if possible.

How do I value TI when the landlord does the buildout directly? If the landlord manages construction, get a line-item budget and third-party cost estimate. Landlords often inflate buildout costs to justify higher rent. Always verify with an independent contractor.

Does the break-even change for a gross lease vs. NNN lease? Yes. In a gross lease, the landlord pays operating expenses, so base rent is a larger share of your total cost — making lower rent more valuable. In a NNN lease, base rent is a smaller share, so TI often wins.
