Enter your plan price, monthly churn and the commission you are considering. The calculator shows what a partner earns per referred customer and what share of that customer's revenue it costs you.
Expected payments use your churn: a customer who stays pays every month until they cancel, and the commission stops after the months you set. Taxes and refunds are not included.
20% to 30% of each payment for 12 months is the most common range. At 5% monthly churn, 20% for 12 months costs about 20% of the revenue a referred customer brings in during that year, because commission only follows payments the customer actually makes.
Commission is paid on each renewal, so a customer who cancels in month 4 earns the partner four payments, not twelve. Higher churn lowers the cost per customer, but each customer is also worth less.
A small bounty ($10 to $50) helps partners see a result on the first sale. Pay it only on a real payment, never on a free trial, and keep it small enough that the recurring share remains the main reward.
