Reference Table
Hour ranges for common Fibonacci point values based on your team parameters. The range reflects typical estimation variance (±25%).
| Story Points | Low Estimate | Expected | High Estimate | Effort Level |
|---|---|---|---|---|
| 1 | 7.5h | 10.0h | 12.5h | Small |
| 2 | 15.0h | 20.0h | 25.0h | Small |
| 3 | 22.5h | 30.0h | 37.5h | Medium |
| 5 | 37.5h | 50.0h | 62.5h | Medium |
| 8 | 60.0h | 80.0h | 100.0h | Large |

A note on story points vs. hours
Story points measure relative effort and complexity, not time. Converting them to hours loses that nuance. This tool is meant for rough capacity planning and communicating estimates to stakeholders who think in hours. Do not use these numbers to track individual developer productivity or hold teams to exact hour commitments.

When to Convert Story Points to Hours
Most agile practitioners agree that story points should stay abstract. They measure relative effort, not clock time. But there are valid reasons to approximate hours: resource planning for fixed-deadline projects, explaining timelines to executives, and calibrating new teams that haven't yet internalized what a "5-pointer" feels like.
The key is using your own team's data. A 5-point story means something different for a team of 3 seniors than for a team of 8 juniors. This calculator uses your actual velocity and capacity to derive a ratio that reflects your team's reality, not a generic industry benchmark.
How the Calculation Works
Total sprint capacity = team size x sprint days x productive hours per day. Dividing that by your average story points per sprint gives the hours-per-point ratio. The reference table applies a ±25% variance to account for estimation uncertainty, which tends to grow with larger stories.
For more accurate velocity data, use the Sprint Velocity Tracker to track completed points across multiple sprints. If you need to prioritize which stories to pull into a sprint, the RICE calculator and WSJF calculator can help rank by value delivered.
Tips for Better Estimates
Use at least 3 sprints of historical data before trusting the ratio. Re-calibrate after team changes (new hires, departures) or process shifts. Keep sprint lengths consistent. Separate spike/research work from feature delivery in your velocity tracking. And remember: the goal is "roughly right," not "precisely wrong."
