fin.net-revenue-retention Calculator
Calculates Net Revenue Retention (NRR) from starting ARR, expansion, contraction, and churn revenue. NRR above 100% means existing customers are growing revenue even before new customer acquisition — the key metric that separates elite SaaS companies from average ones.
Inputs
Arr Start
Time for one complete cycle (s). Period = 1 / frequency. A 50 Hz signal has a 20 ms period.
Expansion
Total income generated before any costs are deducted. Profitability depends on how much survives after expenses.
Churn
Total income generated before any costs are deducted. Profitability depends on how much survives after expenses.
Contraction
Total income generated before any costs are deducted. Profitability depends on how much survives after expenses.
