Subscription Cancellation Refund Calculator

About this calculator

Many subscription services that offer prorated refunds calculate them on a simple time-remaining basis: refund = amount paid × (unused days remaining in the billing period ÷ total days in the period), so canceling a $120 annual plan after 90 days of a 365-day term returns roughly $90.41 rather than a flat percentage or nothing at all. The exact policy varies by company — some refund only unused full months, others go day-by-day, and some offer no proration at all.

This calculator takes the amount paid, the billing period length, and the number of days already used, and returns the prorated refund under a straightforward day-based model. Subscribers requesting a cancellation refund, customer support teams processing requests consistently, and SaaS billing teams designing or auditing a proration policy use it to see the expected refund before a request is filed or approved.
