How much time do you get back?

Move the sliders. The calculation deducts review time honestly, because a person reviews everything.

Each block is an hour that flows back to your team.

How we calculate

The formula, with no hidden tricks.

  1. Postponed work per week is the number of developers multiplied by the hours each of them loses per week to maintenance, small bugs, testing and documentation.
  2. Work taken over is the share of that an agent can carry out. How much that is depends on your code and your tasks. By default we assume half.
  3. Review time is the time your team needs to review the proposals. We deduct it.
  4. Per year we assume 46 working weeks (52 weeks minus 20 days of holiday and 10 public holidays) and a working day of 7.6 hours (38 hours per week). [24, 23, 22]
  5. The cost of an hour is set to €65 by default: our own calculation based on Belgian salary data, employer contributions and benefits. [26, 25, 27]

The default of 8 hours of postponed work is deliberately cautious. Developers themselves estimate that they spend an average of 17.3 hours per week on maintenance. [5] All assumptions and sources are on our page with calculation assumptions.

This is an estimate, not a promise. Your real figures depend on your code, your team and the kind of work. In the free scan we run the calculation with your data.
