1.2m starting ARR growing to 1.8m: 50% YoY growth, 600k new ARR. Top-tier SaaS growth 50%+ at this scale. Growth slows as base expands — each doubling harder. Benchmark against stage: seed 100%+, growth stage 50-100%, mature 20-30%.

Run it with sensible defaults

Using starting arr of 1,200,000, ending arr of 1,800,000, the calculation works out to 50.00%. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Starting ARR and Ending ARR — do not pull with equal force. The rate and the time horizon usually dominate — compounding means a small change in either reshapes the final figure more than a similar shift in contribution size. Test this by doubling one input at a time.

How the math works

Standard growth formula. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".

What to do with a low result

A disappointing result is information, not a judgement. Pick the single input that dragged the figure down most and focus the next quarter on that one factor. Breadth-first improvement rarely works; depth-first on the worst input usually does.

What this doesn't capture

The score is a composite of the inputs you provide. Life context — job security, family obligations, health, housing — doesn't appear in the math but shapes the real picture. Use the number as a prompt, not a verdict.

Related calculations worth running

Plans get firmer when you triangulate. Alongside this one, the mrr growth calculator, the saas rule of 40 calculator, and the arr calculator tend to come up in the same conversations. Running two or three together exposes inconsistencies in any single assumption — which is usually where the useful insight lives.

Frequently Asked Questions

Benchmarks by size?
<1m ARR: 100%+ typical. 1-10m: 50-100%. 10m+: 30-50%. 100m+: 20-30%.
Net vs gross?
Net = new ARR minus churn. Gross = only new ARR. Net growth most meaningful. Track both.
Compound vs linear?
High compounding rates don't sustain. 100% growth × 5 years = 32x. Few companies achieve this.
Seasonality?
Quarterly growth often uneven. Compare to same quarter prior year for smoothed view.
