How it works
Productivity loss from bugs
When bugs reach users, they lose time. Field workers lose more than office staff because workarounds are harder on-site. Cost = users x estimated disruption hours per event x events per year x average fully-loaded hourly cost.
Engineering re-work cost
Every bug that reaches users came from code that had to be fixed and re-shipped. Teams with frequent bugs spend 25-45% of their engineering time on re-work rather than new features. Cost = team size x monthly engineering cost x re-work fraction.
Feature delay cost
Slow release cycles mean operational improvements wait in a queue. The longer the gap between releases, the more time workers spend on manual workarounds for processes the app should already handle.
Questions
What formula does this use?
Annual cost = productivity loss from bugs + engineering re-work cost + feature delay cost. Each component uses your user count, user type, bug frequency, ship frequency, and team size. The methodology section shows the full formula and every assumption.
Why is there no revenue input?
Most enterprise mobile apps — field ops, logistics, healthcare, internal tools — do not generate direct revenue. The cost of bad delivery shows up in lost staff time, engineering waste, and delayed operational improvements. This calculator measures those things.
How accurate is this?
Accurate enough to have a board conversation. The hourly rates come from BLS data, the re-work fractions from Wednesday engagement data and DORA 2024. The result is directional, not an audit.
When should I not rely on this calculator?
If your app is pre-launch or if your team is very new to mobile, the re-work benchmarks may not apply yet. Book a call for an estimate tailored to your specific situation.
Who should I talk to if my situation is more complex?
Book 30 minutes with one of our engineers. You will leave with a written estimate tailored to your team shape, delivery history, and user base.
