## Formula

Deployment frequency = Deployments to production / Length of the period

- Deployment frequency = Deployments to production / Length of the period.
- Inputs used: Deployments to production, Length of the period.
- Edge handling: Deployments to production is required.; Deployments to production cannot be negative.; Deployments to production must be no more than 1000000000000.; Length of the period is required.; Length of the period cannot be negative..

## Inputs

- Deployments to production
- Length of the period

## Worked example: 86 production deployments in 30 days

A rate over your own period. It is not compared with any performance band.
1. Start with Deployments to production: 86, Length of the period: 30.
2. Apply the method: Deployment frequency = Deployments to production / Length of the period.
3. A rate over your own period. It is not compared with any performance band.

## Common questions

### Where does this formula come from?

Deployment frequency is deployments to production divided by the length of the period; change failure rate is the share of changes to production that cause degraded service requiring remediation; failed deployment recovery time is the time taken to restore service after such a change. See the source link on this page.

### What kind of calculation is this?

Production deployments divided by the days they were made over, with the mean gap between deployments. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.

### What are its limits?

Arithmetic over the figures entered — it cannot tell whether the underlying monitoring, incident records or change records are complete. A mean over a short period, or over few events, is a weak description of behaviour. A rate says nothing about the size or risk of each deployment.

### How do I use the Deployment Frequency Calculator?

Enter the required values for Deployments to production, Length of the period. The calculator applies the formula on this page and shows the main result with any supporting breakdown so you can check the arithmetic.

### What formula does the Deployment Frequency Calculator use?

Deployment frequency = Deployments to production / Length of the period The visible formula section above lists the calculation path and the edge cases the page handles, so the result can be checked without relying on the form alone. Check the formula, example, and limitations on this page before using the result for a real professional & industry decision.

### Can the Deployment Frequency Calculator be used for exact decisions?

Use it as a calculation aid, not as a substitute for checking the underlying rule, contract, policy, or professional advice that applies to your situation. When a result depends on local rules, personal details, prices, or dates, enter those values yourself and confirm them before acting.

## Limitations and assumptions

- Inputs outside the supported range are rejected rather than forced into a result.
- The result depends on the values you enter for this deployment frequency calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
