About FinOps Unit Economics Calculator

Absolute cloud spend is a poor signal in a growing business — it should rise. Unit economics is what matters: cost per active user and cloud spend as a share of revenue. A rising bill with a falling cost per user is healthy scaling; a flat bill with a rising cost per user means efficiency is deteriorating even though finance sees no problem.

Formula

Unit economics

cost per user = spend / active users; cloud cost ratio = spend / revenue; infrastructure gross margin = (revenue - spend) / revenue

Worked example

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

What cloud cost ratio is healthy?

SaaS businesses typically target under 15 to 20 percent of revenue on infrastructure, though it varies enormously by product. The trend matters more than the absolute figure.

Which unit should be used?

Whatever drives cost. Active users work for consumer products; for a data platform it might be gigabytes processed or API calls served.
