Frequently Asked Questions (FAQ)

How is technical debt cost calculated?

Monthly debt cost = Wasted Hours × Hourly Rate × Team Size. Bug cost = Bug Frequency × (Rate × 0.5), assuming each bug takes ~30 minutes to diagnose and fix. Total annual cost is simply the monthly total multiplied by 12.

How is the refactoring ROI determined?

We estimate refactoring costs at 3× your monthly debt cost, and assume it eliminates 80% of ongoing debt cost. The payback period shows how many months until the savings from refactoring exceed the upfront investment.
