What Would It Take to Reach 110% NRR?

You need in additional expansion MRR to reach 110% NRR.

Enter your numbers above to see the gap.

How NRR Is Calculated

NRR = (Starting MRR − Churned MRR − Contraction MRR + Expansion MRR) ÷ Starting MRR × 100

NRR only measures what happens to your existing customer base — new customers are excluded. An NRR above 100% means your existing customers grow your revenue even without any new sales, creating compounding growth.
