Hidden Tech Debt Cost Calculator for B2B Apps
How to calculate the hidden tech debt cost of maintaining a legacy B2B application?
Direct Answer Definition
Mid-market companies waste $180,000–$360,000 annually maintaining legacy B2B applications — roughly 20–30% of engineering time on patches instead of revenue features. When maintenance exceeds 20% of engineering output, a owned custom rebuild typically breaks even in 12–18 months. Book a free assessment call.

Frequently Asked Questions
What is the biggest source of hidden tech debt cost?
Lost engineering velocity. Paying a senior developer $160,000/year to debug monolithic spaghetti code instead of shipping new revenue-generating features.
How long does a rebuilding ROI take?
For mid-market SaaS or internal tools, a professional rebuild from Slickrock.dev typically hits pure financial break-even in 2.1 months post-launch.
