Gross Margin
Definition
Recognized revenue minus cost of goods sold (COGS), divided by recognized revenue, expressed as a percentage. The single best read on whether the business model can ever generate operating leverage — a low gross margin caps every downstream efficiency metric (CAC payback, LTV/CAC, Rule of 40). For SaaS, COGS includes hosting, third-party software, customer support, and customer-success cost-of-service. Common pitfall: omitting customer success from COGS inflates the margin and breaks comparability with peer benchmarks. Anchored to KBCM/Sapphire SaaS Survey 2024 §Gross Margin.
Why it matters
Caps every long-term efficiency metric — Rule of 40, LTV/CAC, CAC payback all run off contribution margin which derives from gross margin. Board uses it to verify the unit economics are real before debating S&M investment levels.
How it's calculated
Gross Margin = ((Recognized Revenue − COGS) / Recognized Revenue) × 100. COGS for a SaaS business: cloud / hosting infrastructure, third-party data and APIs called for delivery, customer support, customer success cost-of-service, and any directly-attributable delivery personnel. Excludes R&D, S&M, and G&A. How to interpret it
Per KBCM/Sapphire SaaS Survey 2024 §Gross Margin, healthy SaaS gross margin is 70–80%; > 80% is best-in-class infrastructure leverage; < 65% usually signals heavy services revenue or inefficient COGS (often customer-success scaling linearly with customer count). Sub-70% companies must show a credible path to 70%+ by next funding milestone or face valuation pressure.

Total revenue recognized under the company's accounting standard (ASC 606 / IFRS 15) during the period — distinct from billings (what was invoiced) and from ARR (an annualized run-rate snapshot). The income-statement top line and the basis for GAAP reporting. Common pitfall: confusing recognized revenue with ARR — for a company with mid-year contract starts, ARR exit will exceed recognized revenue for that year; the gap shrinks as the cohort matures. Boards reviewing a recognition-heavy investor pack should always see ARR alongside revenue to avoid mis-pricing growth.
Annual Recurring Revenue — the value of all recurring subscription revenue normalized to a one-year run-rate as of the period close. The headline operating metric for a subscription business; every growth and efficiency ratio (NRR, GRR, magic number, CAC payback, Rule of 40) is calibrated against it. Excludes one-time fees, professional services, and non-contractual usage. Common pitfall: confusing ARR (contracted recurring) with revenue (recognized) or with CARR (contracted incl. not-yet-live) — the SMSB standard draws sharp lines between them, and boards expect the same discipline. The KpiVarianceTable widget surfaces forecast / actual / variance / status / future-forecast columns against the same field.
Number of months required for the gross profit generated from a new customer's ARR to recover the fully-loaded S&M spend used to acquire them. The single most decision-useful efficiency metric at the board level — it directly connects acquisition cost, ACV, and gross margin into one "how long until we break even on this customer" answer. Per the SMSB standard, the calculation must use gross-margin-adjusted ARR in the denominator (not raw ARR) to be cross-company comparable. Common pitfall: using raw ARR understates payback by ~25–30 percentage points and breaks comparability with peer benchmarks.
Composite SaaS health score that sums the company's revenue growth rate and a profitability proxy (commonly EBITDA margin or free-cash-flow margin) into a single percentage. Originally articulated by Brad Feld in 2015 and codified by the SaaS Metrics Standards Board, the rule frames the growth-vs-profitability tradeoff: a company growing at 60% with a −20% margin scores 40, equal to a company growing at 20% with a +20% margin. The board reads it to sanity-check whether growth is being bought at unhealthy burn or whether margin discipline is constraining growth too far. Common pitfall: which profitability proxy is used materially changes the score (FCF margin is the strictest, EBITDA more flattering, "operating margin" inconsistently defined), so pick one and disclose it next to the number.
Year-over-year percentage growth in ARR (or recognized revenue, if explicitly anchored) — comparing the current period to the equivalent period 12 months prior. The single most-watched investor metric and the largest single driver of SaaS valuation multiples. Common pitfall: comparing to the prior quarter (QoQ) and reporting it as "growth rate" — boards and investors mean YoY unless explicitly noted otherwise. Anchored to KBCM/Sapphire SaaS Survey 2024 §YoY ARR Growth for cross-company benchmarking.
