Deployment Frequency Calculator
Calculate deployment frequency and classify it into DORA performance tiers: Elite, High, Medium or Low.
Inputs
Number of production deployments observed in the chosen period.
The time unit the deployment count above was measured over.
Deployments per Day
0.714
DORA Category
High (between once per day and once per week)
Deployments per Week
5.00
Deployments per Month
21.43
Deployments per Year
260.7
Step by step
Normalize to per-day rate
5 ÷ 7 days
= 0.714 deploys/day
Per-week rate
0.714 × 7
= 5.00 deploys/week
Per-month rate
0.714 × 30
= 21.43 deploys/month
How it works
Deployment Frequency is one of the four key DORA metrics, measuring how often an organization successfully releases to production. This calculator normalizes any input period to a common per-day rate and classifies it against the DORA performance tiers: Elite teams deploy on-demand, multiple times per day; High performers deploy between once per day and once per week; Medium performers deploy between once per week and once per month; Low performers deploy less often than monthly.
Formula
deploymentsPerDay = deploymentsPerPeriod / periodDays

Frequently Asked Questions
What deployment frequency counts as 'Elite' in DORA?
On-demand deployment, typically multiple times per day, is the Elite tier in Google's State of DevOps DORA research.
Does deployment frequency measure commit frequency instead?
No — it specifically measures how often code successfully reaches production, not how often developers commit or open pull requests.
Why does DORA pair deployment frequency with change failure rate?
Shipping frequently only reflects healthy delivery practice if failure rate stays low — the two metrics are meant to be read together to distinguish 'fast and safe' from 'fast and risky' delivery.
How can teams increase deployment frequency safely?
Smaller batch sizes, trunk-based development, feature flags, comprehensive automated testing, and progressive delivery (canary/blue-green) are the standard levers for increasing frequency without raising risk.
