Industry Benchmarks: Typical Margins & Markups
Compare your numbers against common verticals before you lock a price. Your required markup must cover overhead plus target profit.
| Industry | Typical net margin | Typical markup | Notes |
|---|---|---|---|
| NRR leaders | 100–120% | 120–150%+ | Best-in-class SaaS expands existing accounts; below 100% means contraction outweighs upsell. |
| GRR defenders | 85–95% | 110–125% | Gross retention excludes expansion; under 85% signals onboarding or fit problems. |
| Logo churn | 3–5% monthly | 40–60% annual | SMB SaaS churns faster than enterprise; segment by cohort before judging. |
| LTV : CAC | 3:1 or better | 4–6x | Below 3:1 the engine burns cash; above 5:1 you may be under-investing in growth. |
| Magic number | 0.75–1.0 | 1.0–1.5 | Net new ARR per sales-and-marketing dollar; under 0.5 means go-to-market inefficiency. |
| Rule of 40 | 40 or higher | 50–60+ | Growth % plus FCF margin % must clear 40 for a healthy SaaS balance. |
| Gross margin | 75–85% | 80–90%+ | True SaaS margins after hosting and support; below 70% looks like services. |
Formulas & How to Use This Calculator
Core formula
Runway (months) = Cash on Hand ÷ Net Burn per Month Worked: $900,000 cash at $75,000 net burn is 12.0 months of runway.
Zero-date check
Cash − (Burn × Months) = $0 at the deadline. Example: $900,000 − ($75,000 × 12) = $0.00.
Gross vs net
Net burn nets revenue; gross burn is spend alone. Example: $75,000 net on $150,000 gross = 50% covered.
How to use — step by step
- Step 1: enter Cash on hand — Bank balance plus committed draws.
- Enter Net burn — Monthly spend minus monthly collections.
- Read the headline runway, check the warning box for zero or impossible inputs, then study the proportional bars.
- Compare against the benchmark table and pick the Starter, Growth or Scale plan that matches your stage.

What SaaS runway actually measures
Every SaaS operating review rests on knowing SaaS runway cold. The relationship Runway (months) = Cash on Hand ÷ Net Burn per Month compresses an entire billing layer into one number you can track monthly. Take the worked case: $900,000 cash at $75,000 net burn is 12.0 months of runway. That single reading tells you whether the period built or drained recurring revenue before the next decision. Founders who review it monthly catch drift early — a two-point slip in churn on a $50,000 base quietly erases $1,000 of MRR every month that headline growth hides. Treat this metric as the first slide of your SaaS review, and make every manager who touches pricing, onboarding, or success able to define it in one sentence. Over four quarters the habit compounds into cleaner forecasts and earlier saves.
The math, step by step
Start with clean same-period inputs from your billing system, never mixing months with quarters or recognized revenue with cash collected. Then apply Runway (months) = Cash on Hand ÷ Net Burn per Month exactly as written, keeping units consistent — dollars with dollars, counts with counts. Work the example: $900,000 cash at $75,000 net burn is 12.0 months of runway. Notice how each operation has a business meaning: multiplication scales a per-unit rate to the base, subtraction isolates what changed, division turns it into a comparable rate. Common slips include dividing by zero on a fresh cohort, annualizing one input but not the other, and rounding mid-calculation. Do the division last, keep two decimals on money and two on percentages, and rerun the page calculator to confirm your hand math matches to the cent before quoting it.
SaaS Runway Calculator versus its closest cousins
Confusing sibling metrics is the costliest beginner error in SaaS analysis. Burn is the speed (dollars per month) while runway is the distance (months left), so the same $75,000 burn means different urgency per balance. In our case: $900,000 cash at $75,000 net burn is 12.0 months of runway — compare that against the cousin before drawing conclusions. Quoting the wrong sibling misprices risk: growth looks funded while the base quietly leaks, or retention looks safe while new sales mask churn. Keep both on one dashboard, label each clearly with its formula, and let this page own the SaaS runway definition your team quotes in board updates and planning docs so nobody blends cohorts again.
Benchmarks and what good looks like
A number without a benchmark is just trivia. The rule here: A healthy reading: 12–18 months of runway after a raise, never planning below 6. Put the worked case against it: $900,000 cash at $75,000 net burn is 12.0 months of runway. If you sit inside the band, protect the routine that got you there — onboarding checkpoints, save plays, quarterly plan reviews. If you sit outside, attack the largest input first rather than spreading effort thin; one big lever (activation, dunning, expansion offers) usually moves SaaS runway more than five small tweaks. Recheck the SaaS benchmark table above for your stage, then set a quarterly target 5–10% tighter than today and assign it one owner.
How SaaS runway drives real decisions
This metric answers how many months of cash remain and when fundraising must close, which makes it a gate for hiring, pricing, and fundraising. Work from the example: $900,000 cash at $75,000 net burn is 12.0 months of runway shows exactly how much recurring headroom the period carries. A healthy reading green-lights growth spending and hiring; a weak one triggers the playbook — tighten onboarding, launch save offers, fix dunning, expand existing accounts. Tie each input to an owner (marketing owns trials, product owns activation, success owns renewals) and review the trio weekly when the metric is soft, monthly when comfortable, always with the live calculator open.
Limits and blind spots
No single metric tells the whole SaaS story, and SaaS runway is no exception. It is a snapshot: $900,000 cash at $75,000 net burn is 12.0 months of runway describes one period, not the trend, and timing spikes (a big annual prepay week, a lump logo loss) can flatter or punish it. It also ignores cohort mix — enterprise stability can hide SMB leakage — and cash timing, since recognized revenue is not collected cash. Pair it with cohort retention curves, the aging buckets, and a 13-week cash forecast; investigate any 10% swing within days, and never let one good reading justify doubling acquisition spend.
Industry Playbooks
Cost structures differ by vertical — here is how to adapt one base price per business type without losing margin.
SaaS startup playbook
SaaS Runway Calculator teams: Early-stage teams should compute Runway (months) = Cash on Hand ÷ Net Burn per Month weekly on a tiny base where one logo swings the rate. On the worked case ($900,000 cash at $75,000 net burn is 12.0 months of runway) the absolute dollars are small, so pair every rate with its dollar pool and chase onboarding and time-to-value before spending on acquisition.
SaaS scaleup playbook
SaaS Runway Calculator teams: At scale, run Runway (months) = Cash on Hand ÷ Net Burn per Month per cohort and plan tier, not just company-wide. The worked case ($900,000 cash at $75,000 net burn is 12.0 months of runway) becomes one cell in a matrix; alert owners when any segment moves 10% so expansion plays and save motions trigger before renewal.
Agency / MSP playbook
SaaS Runway Calculator teams: Retainer agencies can reuse Runway (months) = Cash on Hand ÷ Net Burn per Month on recurring seats and care plans. With the worked case ($900,000 cash at $75,000 net burn is 12.0 months of runway) as baseline, separate project revenue from recurring revenue first, then apply save and expansion plays to the recurring base only.
E-commerce subscription playbook
SaaS Runway Calculator teams: Subscription boxes and memberships map Runway (months) = Cash on Hand ÷ Net Burn per Month onto subscriber counts and box ARPU. Using the worked case ($900,000 cash at $75,000 net burn is 12.0 months of runway), watch involuntary churn (failed payments) with dunning, and test annual prepay to lift retention.
Glossary: Key Terms Explained
- Monthly Recurring Revenue (MRR)
- Normalized recurring revenue per month; excludes one-time fees and usage spikes.
- Annual Recurring Revenue (ARR)
- MRR times 12 (or contracted annual recurring total); the headline scale metric for SaaS.
- Net Revenue Retention (NRR)
- Revenue retained plus expansion from a starting cohort, including upsell; over 100% means the base grows without new logos.

- Share of customers lost in a period; distinct from revenue churn, which weights by dollars.
- Net burn
- Monthly spend minus monthly revenue collected.
- Gross burn
- Total monthly spend ignoring revenue.
- Zero date

- Bridge
- Short funding to extend runway to a milestone.
Common Mistakes & Pro Tips
Mistakes that kill margin
- Using bank balance without subtracting committed payroll.
- Annualizing one input but not the other.
