PolskiProject monthly recurring revenue, new customers, churn and price changes over up to 60 months.
All monetary amounts use the same currency and exclude VAT. Example values are assumptions, not provider prices. Inputs and calculations stay in the browser.
Calculation model and assumptions
Churn reduces customers and MRR at the start of the month at the same rate. Expansion and contraction apply separately to retained MRR. New customers enter at month end at the entered net price. NRR = retained MRR after price changes ÷ opening MRR × 100, excluding new customers. ARR = final MRR × 12, not annual revenue. Customer counts are expectations without intermediate rounding.

FAQ
Are inputs transmitted?
The calculator processes inputs locally in the browser. CSV files are also generated locally. The page does not store scenario inputs on the server.
What are the model limitations?
MRR normalizes recurring contract values to one month. Payment timing, refunds and one-time sales are not modeled. Fractional customers arise from the statistical churn assumption.
