About this tool
Technical Debt Calculator
The Technical Debt Calculator computes SQALE-method debt ratio, total remediation time, dollar cost, and payback priority from code smell count and development estimates.
• Calculate technical debt ratio for a quarterly engineering health report
• Estimate the dollar cost of technical debt for a budget proposal to management
• Determine whether debt remediation should be done now or deferred based on payback period
• Build the business case for a refactoring sprint with concrete cost numbers

FAQ
What does this tool tell you?
The Technical Debt Calculator computes SQALE-method debt ratio, total remediation time, dollar cost, and payback priority from code smell count and development estimates.
What affects the result most?
Technical debt ratio: remediation_time / total_dev_time — SonarQube uses 30 min per complexity point. SQALE method: debt in minutes per code smell × fix_cost_per_smell type. Interest rate: high-debt code requires more time to modify — debt_additions / sprint_velocity reduction.
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.
