DORA Metrics Score Calculator

Work out dora metrics score instantly with clear inputs, formula shown and shareable results.

About DORA Metrics Score Calculator

The four DORA metrics split into throughput — deployment frequency and lead time — and stability — change failure rate and time to restore. The research finding that matters is that these do not trade off: elite performers score well on all four, because small frequent changes are both faster to ship and easier to diagnose when they fail.

Formula

DORA banding

each metric scored 1-4 against elite/high/medium/low thresholds; overall = mean of the four; elite is on-demand deploys, under a day lead time, under 5% failure, under one hour restore

Worked example

With the default values below, DORA Metrics Score Calculator returns DORA score (1-4) of 3.25. Change any input above and every figure here is recalculated in your browser.

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 2 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

Do throughput and stability really not trade off?

That is the consistent finding across years of the DORA research. Large batched releases are riskier, so shipping less often does not buy stability.

Which metric should be improved first?

The weakest, and usually deployment frequency, because raising it forces smaller batches which improves the other three as a side effect.
