How to use this guide
Investors evaluate a SaaS business through a small, consistent set of metrics that translate product traction into a story about durable, capital-efficient growth. This guide collects the standard formulas across five areas — revenue, retention, unit economics, sales efficiency, and cash & profitability — plus the composite scores boards rely on. Each metric gives you the definition, the exact formula, current market benchmarks, and a note on what investors actually read into the number.
A word on consistency. The specific number matters less than calculating it the same way every period and being able to defend your definition. The fastest way to lose credibility in a diligence call is to present a metric you can't reconstruct from raw data. Pick a definition, document it, and apply it uniformly across every cohort and reporting period.
Three rules of thumb investors apply: (1) recurring revenue is worth far more than one-time revenue, so isolate it cleanly; (2) retention is the single strongest predictor of long-term value, so expansion and churn get scrutinized hardest; and (3) growth must be paid for efficiently — fast growth funded by unsustainable burn is discounted heavily in today's market.
Recurring revenue is the foundation of SaaS valuation. These metrics quantify the size, growth, and composition of the predictable revenue base.
The normalized, predictable subscription revenue a company expects every month. Exclude one-time fees, professional services, and usage overages that aren't contractually recurring.
Per-customer shortcut: MRR = Number of customers × ARPA (average revenue per account). Annual contracts are divided by 12 to express them monthly.
The annualized value of recurring revenue. The headline number for most growth-stage and later companies, and the denominator in many efficiency ratios.
Decomposing the change in recurring revenue across a period into its sources. This is the most diagnostic revenue view investors ask for.
The average recurring revenue generated per customer (account) or per user. Tracks pricing power and how the customer mix shifts over time (e.g., upmarket movement).
The percentage increase in recurring revenue over a period. Usually reported year-over-year (YoY) at later stages and month-over-month (MoM) for early-stage companies.
Retention is the strongest predictor of long-term value. A company that retains and expands its base compounds; one that leaks revenue must run ever-faster just to stay level. Investors scrutinize these metrics more than almost any others.
The percentage of recurring revenue retained from existing customers over a period, including expansion and contraction but excluding new customers. Above 100% means the existing base grows on its own — the gold standard of SaaS health. Also called Net Dollar Retention (NDR).
The percentage of recurring revenue retained excluding any expansion. It strips out upsell to reveal the raw "leakiness" of the base. GRR can never exceed 100%.
The percentage of recurring revenue lost over a period. The inverse companion to retention.
The percentage of customers (logos) lost over a period, regardless of their size. Counts heads, not dollars.
The simple inverse of logo churn — the share of customers kept over a period.
Unit economics answer the central question: does acquiring a customer create more value than it costs? These metrics determine whether growth is fundamentally profitable or whether the company is buying revenue at a loss.
The fully loaded cost to acquire one new customer: all sales and marketing expense (salaries, commissions, ad spend, tools, overhead) divided by the number of customers won in the period.
Blended vs. paid: Blended CAC includes organic customers; paid CAC isolates only customers from paid channels. Investors often want both, since blended CAC can flatter a company riding organic word-of-mouth.
The total gross-margin revenue a company expects from a customer over the entire relationship. The value side of the acquisition equation.
Why divide by churn: 1 ÷ churn rate is the average customer lifetime in periods. Always use gross-margin-adjusted revenue, not raw revenue — investors discount LTV figures that ignore cost of service.
The return on each dollar spent acquiring customers. The headline unit-economics ratio.
The number of months it takes to recoup the cost of acquiring a customer from their gross-margin contribution. The most cash-flow-relevant unit-economics metric.
The percentage of revenue left after the direct cost of delivering the service (hosting, infrastructure, support, third-party fees). Determines how much of each revenue dollar is available to fund growth.
These metrics measure how efficiently the company converts spend into new recurring revenue — the engine-room view of whether growth scales profitably.
How much new ARR each dollar of sales & marketing generates, measured with a one-quarter lag. A clean read on go-to-market efficiency.
How much cash the company burns to generate each dollar of net new ARR. The shorthand VCs now use to judge capital discipline — lower is better.
Operational sales metrics that shape forecasting and pipeline math.
Sales cycle length: average days from first qualified contact to closed-won. Longer cycles tie up cash and complicate forecasting.
Win rate: opportunities won ÷ total qualified opportunities. Feeds pipeline-coverage planning.
Pipeline coverage: total pipeline value ÷ revenue target. ~3x is a common rule of thumb to hit quota.
The ratio of revenue gained (new + expansion) to revenue lost (churn + contraction). Measures growth durability — how much the company adds for every dollar it loses.
These metrics describe survival and the path to profitability — the constraints inside which all growth must happen.
Gross burn is total monthly cash spent; net burn is monthly cash spent minus cash collected. Runway is how many months of cash remain at the current net burn.
A composite health check: a company's revenue growth rate plus its profit margin should sum to at least 40%. It captures the core SaaS trade-off — fast-but-unprofitable and slow-but-profitable can both be healthy; the combination is what matters.
Profit margin: typically EBITDA, free-cash-flow, or operating margin — state which you use.
Cash generated from operations after capital expenditure. FCF margin is FCF divided by revenue. The ultimate measure of self-sustaining economics.
Recurring revenue divided by full-time headcount. A blunt but widely tracked measure of organizational efficiency that investors watch trend over time.
A one-glance cheat sheet of the core metrics and their healthy targets. Benchmarks are directional and vary by stage, segment, and business model — use them as conversation starters, not absolutes.
Define every metric in a footnote. State exactly what's included (e.g., does ARR include usage revenue? Is CAC blended or paid?). Consistency beats flattery.
Show components, not just net numbers. Break MRR growth into new/expansion/contraction/churn. The composition is the insight.
Pair retention metrics. Always show NRR with GRR, and logo churn with revenue churn — each pair guards against a misleading single number.
Report cohorts over time. Cohort retention curves reveal whether the product is getting stickier or leakier in a way period averages hide.
Tie efficiency to cash. Lead with CAC payback and burn multiple in today's market — investors weight capital efficiency heavily.
Never present a number you can't rebuild. Every metric in a board deck should be reconstructable from raw data on request.
Benchmark figures reflect 2025–2026 B2B SaaS market data and are directional. Always validate against your stage, segment, and business model before reporting.
