Quick answer
Velocity is the story points a team completes per sprint, used to forecast delivery.
Sprints = backlog points ÷ velocity

Frequently asked questions
Why include scope creep?
Backlogs grow during delivery; ignoring it makes every forecast optimistic.
Should velocity be a target?
No — it is a measurement, and targeting it corrupts estimates.
What do I need to enter into the Sprint Velocity Calculator?
Just 4 values: backlog points, average velocity, sprint length, scope creep per sprint. Every field starts with a realistic example, so you can change one number at a time and watch the result update instantly.
How does the Sprint Velocity Calculator work out the answer?
Velocity is the story points a team completes per sprint, used to forecast delivery. It applies the formula Sprints = backlog points ÷ velocity and shows the working so you can check each step by hand.
Is the Sprint Velocity Calculator free, and do I need an account?
It is completely free with no sign-up, no download and no usage limit. Everything is calculated in your browser, so the numbers you type never leave your device.
