Compounded NRR

NRR of 108% means your base holds and grows slightly. Solid, but lifting expansion a few points dramatically changes the three-year picture.

NRR above 100% means existing customers alone grow revenue. It's the single strongest driver of both compounding growth and valuation multiple.

About this calculator

Combine gross churn and expansion into a net revenue retention rate and forecast how your current customers alone grow (or shrink) ARR over three years.
