DORA Metrics Calculator

Score the four DORA delivery metrics and assign a performance tier.

About DORA Metrics Calculator

DORA splits into throughput and stability, and the research finding is that these improve together rather than trading off. Teams deploying more often generally also fail less and recover faster. The counterintuitive result is that slowing down to be careful makes stability worse, because larger batches are harder to diagnose when they fail.

Formula

DORA Metrics

Each metric is banded into Elite, High, Medium or Low, then averaged

throughput metrics: Deployment frequency and lead time
stability metrics: Change failure rate and time to restore service

Worked example

With the default values below, DORA Metrics Calculator returns Overall Performance Tier of High. Change any input above and every figure here is recalculated in your browser.

Inputs used

Deployments per weekminimum 0: 5
Lead time for changesminimum 0 h: 20 h
Change failure rateaccepts 0–100 %: 12 %
Time to restore serviceminimum 0 h: 3 h

Results

Overall Performance Tier: High
Deployment Frequency Tier: High
Lead Time Tier: Elite
Change Failure Rate Tier: Medium
Time to Restore Tier: High

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.

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

Frequently Asked Questions

How is DORA Metrics calculated?

Each metric is banded into Elite, High, Medium or Low, then averaged DORA splits into throughput and stability, and the research finding is that these improve together rather than trading off. Teams deploying more often generally also fail less and recover faster.

Why does DORA Metrics matter?

The counterintuitive result is that slowing down to be careful makes stability worse, because larger batches are harder to diagnose when they fail.

What values do I need to enter?

This calculator takes 4 inputs: Deployments per week, Lead time for changes, Change failure rate, Time to restore service. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
