FAQ
What does this tool tell you?
The Technical Debt Cost Estimator computes monthly debt interest cost from delivery overhead and team rate with refactoring break-even calculation.
What affects the result most?
Technical debt interest: extra time per feature due to messy code — typically 10-40% overhead. SQALE method: principal (fix cost) + interest (ongoing slowdown) — total debt cost. Code complexity correlation: cyclomatic complexity > 10 → 2-3× higher defect rate.
How should I use the result?
The calculation is deterministic — the same inputs always produce the same output — so the most useful workflow is to vary one input at a time and see which factor moves the result most. That tells you where to focus your attention before committing to a decision.
