What are the key sales KPIs for the Internet / Broadband industry in 2027?

Direct Answer

In 2027, the nine sales KPIs that actually move an Internet / Broadband P&L are: (1) Net Subscriber Adds, (2) Penetration Rate %, (3) ARPU $, (4) Churn %, (5) Installation Truck Roll Cost, (6) Fiber/HFC/DOCSIS Technology Mix %, (7) Promotional Discount Run-Off Rate, (8) Bundle Take Rate %, and (9) Speed-Tier Upgrade Rate.

Broadband is a passings-and-penetration business, not a pipeline business — your sales motion is constrained by where fiber/coax physically reaches, regulated by the FCC, and measured on a multi-year capex payback. The operators winning in 2027 (AT&T Fiber, Verizon Fios, T-Mobile Home Internet) are the ones reporting net adds and ARPU growth simultaneously, while cable incumbents (Comcast, Charter) defend against fixed-wireless erosion by upgrading DOCSIS 4.0 and bundling mobile.

1. Why broadband sales work differently than every other industry

Broadband is the most physically constrained sales motion in the Pulse industry taxonomy. You cannot sell a subscriber the network doesn't reach, and the network is funded by 10-year capex cycles — Comcast and Charter spend $9-11B/year, AT&T spent $24B in 2026 chasing 30M fiber passings by 2027. That structural reality reshapes every KPI:

• Infrastructure-bound TAM. Your serviceable addressable market is not "households in the DMA" — it is homes passed by your plant. A rep in Tulsa cannot sell Fios; a rep in Tampa cannot sell Spectrum to a Verizon footprint. Penetration of homes passed is the only honest growth ceiling.
• Regulated pricing & disclosure. The FCC's Broadband Consumer Labels (mandatory since April 2024, enforcement tightened 2026) force every operator to publish all-in prices, throttle thresholds, and contract terms at the point of sale. Hidden fees that used to inflate ARPU now show up on the label — and in churn 14 months later.
• Multi-year capex payback. A fiber drop costs $600-1,200 per home; a payback window of 24-36 months means churn at month 18 is a P&L disaster, not a quarterly miss.
• Fixed-wireless vs. Fiber competition. T-Mobile and Verizon 5G Home crossed 11.4M combined subs by Q4 2026 (Leichtman Research Group), siphoning the low-end of cable's base. Cable's counter is DOCSIS 4.0 multi-gig and aggressive mobile bundling.

2. The 9 KPIs — deep dive

2.1 Net Subscriber Adds

The headline number every broadband CEO reports first. Net Adds = Gross Adds – Disconnects for the period. In 2027 the top-quartile fiber overbuilder (AT&T Fiber, Frontier, Lumen Quantum Fiber) targets 20-30% YoY growth in fiber net adds; cable incumbents are defending flat-to-slightly-negative broadband net adds and making it up in mobile.

Watch the mix: a positive net add number masquerading as growth while fiber gross adds collapse is the classic 2026-27 cable trap.

2.2 Penetration Rate %

Subscribers ÷ Homes Passed. Mature cable systems run 45-55% penetration; new fiber builds ramp from 5% (year 1) toward a stabilized 35-45% (year 5-7). MoffettNathanson's 2026 model assumes AT&T Fiber stabilizes at 38% penetration of its 30M passings — every point above/below moves the equity story by ~$3B in NPV.

2.3 ARPU ($ per subscriber per month)

2027 broadband-only ARPU benchmarks: Charter $74, Comcast $76, AT&T Fiber $69, Verizon Fios $68, T-Mobile Home Internet $50-60. ARPU growth comes from speed-tier upgrades, equipment rental, and price-pack changes — never from one-time fees, which the FCC label now exposes. Healthy operators grow ARPU 2-4%/year.

2.4 Churn %

Monthly involuntary + voluntary disconnects ÷ subscribers. Fiber best-in-class: 0.9-1.2% monthly (≈11-14% annualized). Cable in fixed-wireless-overlap markets: 1.6-2.1% monthly (≈19-25% annualized). Every 10 bps of monthly churn improvement is worth roughly $200-400 of LTV per sub.

2.5 Installation Truck Roll Cost

Loaded cost per dispatched install or service call. Industry median $125-185 (Leichtman 2026 ops survey). Self-install rates above 60% (Comcast, Charter target) compress this dramatically; rural fiber builds where every install is a truck roll see $250-400. The leading indicator: first-call resolution rate — every repeat truck roll on a new install destroys CAC payback.

2.6 Fiber / HFC / DOCSIS Technology Mix %

What share of your subscribers sit on FTTH vs. HFC running DOCSIS 3.1 vs. DOCSIS 4.0 upgraded plant. Investors in 2027 pay a 6-9x EBITDA multiple for fiber subs and 4-5x for HFC subs (MoffettNathanson). Charter and Comcast are explicitly reporting "DOCSIS 4.0 homes passed" as a KPI to close the multiple gap.

2.7 Promotional Discount Run-Off Rate

The percentage of subscribers whose 12 or 24-month promo price steps up to rack rate without churning. Healthy operators run-off 55-70% of promos to full price; weak ones see 35-45% and the rest either negotiate retention discounts or churn. This is the single most under-reported KPI in cable — it is the bridge between gross adds and real ARPU.

2.8 Bundle Take Rate %

% of broadband subs also taking mobile, video, or home phone. Comcast Xfinity Mobile: ~14% attach; Charter Spectrum Mobile: ~17% attach and growing 25%/year. Bundle take rate matters because bundled subs churn 40-60% less than single-product subs (NCTA 2026 churn study). It is the cable defense against fixed-wireless.

2.9 Speed-Tier Upgrade Rate

% of base that upgrades to a higher speed tier per quarter. With OpenVault reporting median household usage at 641 GB/month and 1-Gig take-rate at 31% by Q4 2026, operators who can drive 2-Gig and multi-gig attach are the ones growing ARPU without rate hikes — which the FCC label makes politically painful.

3. How real operators measure this in 2027

• Comcast / Xfinity — Reports broadband net adds, ARPU, and Xfinity Mobile lines on the quarterly call; internal scorecard weights bundle attach and DOCSIS 4.0 passings. Lost ~120K broadband subs in 2026 to fixed-wireless; defending with NOW prepaid and mobile.
• Charter / Spectrum — The bundle thesis. Spectrum Mobile is the growth engine; broadband-mobile attach is the board KPI. Reports "internet customer relationships" rather than raw subs to obscure standalone losses.
• AT&T Fiber — Pure fiber net adds and ARPU. Targeted 30M+ fiber passings by 2027, currently the fastest-growing wireline ARPU in the industry (+3.5% YoY).
• Verizon Fios + Verizon 5G Home — Reports them separately. Fios penetration is mature (~42%); 5G Home is the growth lever, crossed 5M subs Q3 2026.
• T-Mobile Home Internet — Reports HSI net adds as a single line. Crossed 6.4M subs Q4 2026 (Leichtman); ARPU intentionally suppressed at $50 to grind cable.
• Frontier, Lumen Quantum Fiber, WOW!, Cox — Penetration ramp curves and fiber net adds are the equity story. Frontier emerged from BK explicitly measured on fiber penetration milestones.

4. Failure modes

1. Confusing homes passed with serviceable subs. Sales teams quoting addresses that show "available" but fail provisioning — kill rate of 8-15% destroys forecasts.
2. ARPU inflation from one-time fees. FCC label now exposes them; the churn shows up at month 12-14.
3. Truck roll cost hidden in opex. Allocate the loaded cost (tech, vehicle, dispatch, repeat visits) to the install or you under-CAC every new sub.
4. Bundle attach reported at signup, not retained. Mobile churns separately; measure steady-state bundle penetration, not point-of-sale attach.
5. Promotional discount evergreen. Reps who reset promo pricing every 12 months to save the sub turn the entire base into a permanent discount cohort.
6. Ignoring fixed-wireless overlap. Markets with T-Mobile/Verizon 5G Home coverage churn 30-50% faster; segment your dashboard by overlap status.

5. Reporting cadence

• Daily: Gross adds, disconnects, truck roll volume, first-call resolution.
• Weekly: Net adds by tech (fiber/HFC), promo run-off cohort, bundle attach on new installs.
• Monthly: ARPU, churn by tenure cohort, penetration by zone, speed-tier upgrade rate.
• Quarterly (board): Penetration curve vs. Plan, DOCSIS 4.0 / FTTH mix, CAC payback by vintage, capex ROIC.

6. 30 / 60 / 90 day rollout

Days 1-30 — Instrument. Pull homes passed by node, reconcile against serviceable address database (kill the 8-15% failed-provisioning ghost inventory). Stand up the 9-KPI weekly scorecard in one dashboard. Lock the definitions of "net add" and "active sub" (no 90-day grace period inflation).

Days 31-60 — Segment. Cohort by tech (fiber / HFC / DOCSIS 4.0), by promo vintage, and by fixed-wireless-overlap status. Identify the 3 worst-penetrating zones and the 3 worst-churning cohorts. Stand up promo run-off and bundle attach cohort reporting.

Days 61-90 — Act. Move marketing dollars to under-penetrated fiber passings, launch retention plays on the highest-churn cohorts, push self-install above 60% in cable footprints, and lock the CFO and Field Ops on the same truck roll cost number. By day 90, every leader in the room is reading the same nine numbers.

FAQ

Q: Is "homes passed" or "homes serviceable" the right denominator? A: Serviceable. Passed-but-not-serviceable is a capex-progress metric, not a sales metric.

Q: How does fixed-wireless change the KPI stack? A: It compresses ARPU (T-Mobile anchors $50) and accelerates the low-end churn cohort. Add a "fixed-wireless overlap" flag to every market.

Q: Should ARPU include equipment rental? A: Yes — but break it out. The FCC label requires the disclosure, and investors are increasingly modeling "service ARPU" separately.

Q: What's the right CAC payback target? A: Fiber: 24-30 months. HFC defended with bundle: 18-24 months. Anything over 36 months is a capex problem masquerading as a sales problem.
