What SaaS and revenue calculators are for

Subscription businesses live or die on a handful of ratios. Lifetime value against acquisition cost tells you whether growth is profitable; churn tells you how fast the bucket leaks; runway tells you how long you have to fix either one. These calculators compute each of them from the inputs already in your billing dashboard.

They suit founders preparing a board update, operators modelling a price change, and anyone sanity-checking a growth plan before committing spend.

How the estimates work

Each tool uses the standard definition of its metric and shows the formula alongside the answer, so a number you present is a number you can defend. Everything runs client-side and updates as you type, which makes it fast to test a range of scenarios instead of a single one.

Results are modelling estimates built on standard SaaS definitions. Reconcile them against your billing and accounting systems before reporting figures externally.

Frequently asked questions

Which SaaS metric should I track first?

Start with MRR and churn. MRR tells you the size of the business and churn tells you how much of it you keep, and almost every other metric — ARR, LTV, runway, valuation — is derived from those two numbers.

What is the difference between MRR and ARR?

ARR is simply MRR multiplied by twelve. Companies selling monthly plans usually lead with MRR, while those selling annual contracts report ARR, but both describe the same recurring run rate.

What LTV:CAC ratio should a SaaS business aim for?

3:1 is the standard benchmark, paired with a CAC payback period under twelve months. Below 3:1 acquisition leaves too little gross profit to fund the rest of the business; well above 5:1 often means you could safely spend more on growth.

How is a SaaS company valued?

On a multiple of ARR, driven mainly by growth rate, gross margin, net revenue retention and the Rule of 40 score. Small private SaaS typically trades between 2× and 6× ARR, with high-growth companies well above that.

Is my data sent anywhere?

No. Every SaaS calculator runs entirely in your browser, so the revenue, cost and churn figures you enter are never uploaded, stored or logged.
