Formulas & How to Use This Calculator

Core formula

Burn = (Starting Cash − Ending Cash) ÷ Months Worked: $1,125,000 down to $900,000 over 3 months is $75,000 monthly burn.

Annualized burn

Annual Burn = Monthly Burn × 12. Example: $75,000 × 12 = $900,000.00 per year.

Net vs gross

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

  1. Step 1: enter Starting cash — Balance at the window start.
  2. Enter Ending cash and Months elapsed — Balance at window end plus length.
  3. Read the headline burn, check the warning box for zero or impossible inputs, then study the proportional bars.
  4. Compare against the benchmark table and pick the Starter, Growth or Scale plan that matches your stage.

What SaaS burn actually measures

Every SaaS operating review rests on knowing SaaS burn cold. The relationship Burn = (Starting Cash − Ending Cash) ÷ Months compresses an entire billing layer into one number you can track monthly. Take the worked case: $1,125,000 down to $900,000 over 3 months is $75,000 monthly burn. 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 Burn = (Starting Cash − Ending Cash) ÷ Months exactly as written, keeping units consistent — dollars with dollars, counts with counts. Work the example: $1,125,000 down to $900,000 over 3 months is $75,000 monthly burn. 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 Burn Rate Calculator versus its closest cousins

Confusing sibling metrics is the costliest beginner error in SaaS analysis. Burn clocks pace while runway dates the deadline, so $75,000 burn means 12.0 months on $900,000 but crisis on $300,000. In our case: $1,125,000 down to $900,000 over 3 months is $75,000 monthly burn — 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 burn 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: falling net burn heading to zero with 12–18 months of runway cover. Put the worked case against it: $1,125,000 down to $900,000 over 3 months is $75,000 monthly burn. 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 burn 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 burn drives real decisions

This metric answers how fast cash drains and how quickly costs must bend, which makes it a gate for hiring, pricing, and fundraising. Work from the example: $1,125,000 down to $900,000 over 3 months is $75,000 monthly burn 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 burn is no exception. It is a snapshot: $1,125,000 down to $900,000 over 3 months is $75,000 monthly burn 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 Burn Rate Calculator teams: Early-stage teams should compute Burn = (Starting Cash − Ending Cash) ÷ Months weekly on a tiny base where one logo swings the rate. On the worked case ($1,125,000 down to $900,000 over 3 months is $75,000 monthly burn) 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 Burn Rate Calculator teams: At scale, run Burn = (Starting Cash − Ending Cash) ÷ Months per cohort and plan tier, not just company-wide. The worked case ($1,125,000 down to $900,000 over 3 months is $75,000 monthly burn) 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 Burn Rate Calculator teams: Retainer agencies can reuse Burn = (Starting Cash − Ending Cash) ÷ Months on recurring seats and care plans. With the worked case ($1,125,000 down to $900,000 over 3 months is $75,000 monthly burn) 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 Burn Rate Calculator teams: Subscription boxes and memberships map Burn = (Starting Cash − Ending Cash) ÷ Months onto subscriber counts and box ARPU. Using the worked case ($1,125,000 down to $900,000 over 3 months is $75,000 monthly burn), watch involuntary churn (failed payments) with dunning, and test annual prepay to lift retention.

Net burn
Spend minus revenue; the true balance drain.
Gross burn
Total monthly spend ignoring revenue.
Burn multiple
Net burn ÷ net new ARR; efficiency of spend.
Default alive
Whether growth outruns burn to breakeven.
