How to Use the Subscription Renewal Calculator
Add each subscription with its name, start date, billing cycle, and payment amount. The calculator finds the next renewal date for each service and converts all costs to an annual equivalent so you can see your total subscription spend at a glance.
The annual cost view is the real eye-opener. A $17.99/month streaming service costs $215.88 per year — easy to miss when you're only seeing individual charges. Services renewing within 7 days are highlighted in red, making this a useful tool for deciding which subscriptions to cancel before the next charge.

Payment processors typically charge on the scheduled calendar date even if it falls on a weekend. Some may charge the next business day — check your specific service's billing policy to be sure.
