Paperphyte/Build wait calculator

What does waiting on the build cost you?

Twelve minutes is a coffee break. Twelve minutes, four times a day, times everyone waiting on the same pipeline, times a year — that is a salary you already pay without having hired anyone.

”Nobody gets budget for four minutes. Everybody gets it for a full-time role.”

Your numbers

10 people

Everyone waiting on the same pipeline.

4 builds

Pushes, PR checks, rebuilds after a fix — anything that starts the pipeline.

12 minutes

From push to verdict. Use the median, not the best run you have seen.

Assumptions

The two numbers worth arguing about. Change them until you find them fair — the result recalculates as you go.

60 %

Nobody sits still the whole time. But few get anything meaningful done in twelve minutes either, and switching tasks has its own cost. We assume 60%.

SEK

Salary, employer contributions and overhead — not a consulting rate. SEK 850 is a low estimate for Sweden.

What the waiting costs you

1,056developer hours lost per year
SEK 897,600per year

That is 0.7 full-time roles doing nothing but waiting.

Per developer that is 4 hours a week — rarely enough for anyone to raise it as a problem.

It shows in the margin

No single wait is dramatic, but together it is several hundred hours a year. Enough to show up in your delivery pace — and just small enough never to reach anyone’s priority list.

How we calculate it

10 developers × 4 builds/day × 12 min × 220 working days
105,600 min/year
105,600 min ÷ 60
1,760 h waiting/year
1,760 h × 60% genuinely lost
1,056 h/year
1,056 h × SEK 850/hour
SEK 897,600

220 working days per year, after weekends, public holidays and five weeks of leave. One full-time role counts as 1,600 hours per year. Both are rounded down — better too low than too flattering.

What to do about it

Start with the most expensive steps: cache dependencies, run the test suites in parallel, and move whatever does not need to block off the critical path. The glossary explains CI/CD, and Developer Experience is the engagement where the pipeline becomes someone's stated job rather than everyone's side task.
