The Challenge

Technical Debt Is Invisible Until It Stops the Business.

Engineering leaders know technical debt is slowing them down — but without a number attached to the cost, it is hard to quantify and justify fixing it. Product and commercial stakeholders see feature velocity as the only metric.

Engineering capacity wasted on maintenance is never quantified
Stakeholders prioritise new features over debt reduction without understanding the cost
No framework to communicate technical risk in business terms

The Technical Debt Cost Calculator gives you a number — the engineering capacity lost to debt, the business value destroyed by slow feature delivery, and the estimated cost of rescue — so the conversation changes.

What Debt Costs

The Four Costs of Technical Debt

Technical debt impacts your business in four measurable ways.

Engineering Capacity Loss

Engineers spending time on workarounds, fire-fighting, and manual processes instead of building value.

Slower Feature Delivery

Every new feature takes longer as complexity and coupling accumulate in the codebase.

Higher Bug Rate

Tightly coupled, poorly tested code produces more bugs — each requiring time to diagnose and fix.

Engineer Attrition

Senior engineers leave codebases they are embarrassed to work in — replacing them costs 1-2x salary.

Missed Revenue

Features delayed by debt are features not generating revenue. The opportunity cost is real.

Series A Risk

Investors penalise companies with high technical debt in valuation and terms — or walk away.

Benchmarks

Technical Debt Benchmarks

Use these benchmarks to understand if your technical debt is under control — or silently slowing your growth.

Under 20% Maintenance Time

High-functioning engineering team. Debt is managed and under control.

20-35% Maintenance Time

Typical growing startup. Debt is accumulating — plan to address it before scaling.

35-50% Maintenance Time

High debt. Feature velocity is measurably impacted. Intervention needed soon.

Over 50% Maintenance Time

Critical. The team is mostly maintaining, not building. Immediate action required.

Cost Impact Level

Low (<$10K/month) — manageable. Medium ($10K–$50K) — needs prioritization. High ($50K+) — impacting growth.

Delivery Impact

<10% delay — healthy. 10–25% — slowing down. 25%+ — serious bottleneck.

FAQ

Common Questions

Yes, completely free. No signup required. Use it to build the business case for addressing technical debt with your product and commercial stakeholders.

Share the number with your product and commercial stakeholders. If maintenance time is over 35%, book a call to discuss a debt rescue programme.

Yes. We run structured Technical Debt Rescue programmes — audit, triage, test restoration, incremental refactoring, and CI/CD — while continuing product development.

We use the strangler fig pattern — incremental replacement of problem areas in parallel with feature development. Production never stops.
