About Monthly Recurring Revenue Calculator

MRR normalises every contract to a monthly figure so annual and monthly plans can be summed. Net new MRR — expansion less churn — is what actually determines whether the base is growing before any new logos are added. Net revenue retention above 100% means the existing base grows on its own, which is the single strongest signal in a subscription business.
