How to Calculate Your Innovation Tax

The Innovation Tax is the percentage of engineering capacity spent maintaining instead of building.

By Richard Ewing·

The Formula

Innovation Tax = Maintenance Hours / Total Hours × 100

Healthy: below 40%. Warning: 40-60%. Critical: 60-80%. Insolvent: above 80%.

Track this weekly. If it's trending upward, your debt is compounding faster than your team can manage it. Every 10% increase in Innovation Tax corresponds to roughly 15% slower feature delivery.
