nurvexTechnical debt has an interest rate, and like any debt, the danger isn't the principal — it's compounding. The cost that shows up on a sprint board is never the real cost; the real cost is everything that becomes slower to build around it.
The tax is paid by every feature after the first one
A shortcut taken to ship one feature on time doesn't just cost that feature — it costs every feature that touches the same code afterward, in the form of extra caution, extra testing, and engineers who route around the mess instead of through it.
That's why technical debt is so easy to underestimate at the moment it's taken on: the bill doesn't arrive until later, and it arrives spread across a dozen unrelated tickets that never get traced back to the original decision.
Pay it down when it's cheap, not when it's urgent
Debt paid down proactively, on a slow week, costs a fraction of debt paid down reactively, under a deadline, after it's already caused an incident. The teams that manage this well treat debt paydown as a normal, recurring line item — not a special project that has to fight for priority against every feature request.
