Developer Productivity Calculator
Measure delivery throughput and the share of capacity lost to unplanned work.
About Developer Productivity Calculator
Throughput per developer week conflates capacity with interruption. Separating focus time shows how much of the shortfall is unplanned work rather than productivity. These figures are useful for capacity planning within a team but not for comparing teams, since story point scales are not shared across them.
Formula
Developer Productivity
Throughput = points ÷ developer weeks; focus share = 100 − unplanned − meeting time
- focus time
- Time actually available for planned delivery work
- developer week
- One developer working for one week
Worked example
With the default values below, Developer Productivity Calculator returns Points per Developer per Week of 8.000. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 5 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
