Agile Project Planning
Calculator.
Turn three sprints of actual performance into a practical project completion forecast. Enter your backlog, sprint schedule, and story points to see your estimated finish date.
Your sprint plan
This free calculator models three completed sprints. Update the sample inputs below to forecast your project. Data stays in your browser and is not saved.
Project forecast
FORECAST COMPLETION DATE
Assumes future sprint velocity matches the average of the three entered sprints.
BACKLOG COMPLETION
Sprint-by-sprint analysis
Variance = (completed − planned) ÷ planned. Remaining backlog is reduced by completed points after each sprint.
| Sprint | Dates | Planned | Completed | Variance | Remaining |
|---|
Forecast with velocity.
Average velocity is the mean of completed points across the three sprints. Remaining backlog equals initial points minus completed points, floored at zero. The calculator divides remaining work by average velocity and rounds up to whole future sprints.
The projected completion date is the end of Sprint 3 plus the estimated additional sprint periods. This is a planning estimate, not a guaranteed delivery date. No export, account, or saved-project functionality is included.
