About this calculator

The Subscription Creep Calculator is a free, single-purpose tool that answers one question: how much are you really spending on subscriptions? Most people can name their subscriptions but very few know the total — and studies consistently show we underestimate it by more than half.

Free and instantNo account, no sign-up, no app to install. Open the page, type your subscriptions, read the number.

Private by designEverything is calculated in your browser. Your subscription list is never sent to a server or stored.

Any billing cycleWeekly, monthly, quarterly and yearly prices can be mixed on one list — everything is normalised to a monthly figure.

Honest numbersThe maths is simple and shown on the page, so you can verify every figure yourself.

How the calculation works

Each price is converted to a monthly cost: weekly prices are multiplied by 52/12 (there are 52 weeks but only 12 months), quarterly prices are divided by 3, and yearly prices are divided by 12. The monthly costs are added together, and the yearly figure is the monthly total multiplied by 12. The five-year figure assumes today's prices hold for 60 months — in practice, subscription prices tend to rise, so it is a conservative floor.

What the preset prices are

The quick-add buttons use typical US prices for popular plans at the time of writing. Streaming and software prices change frequently and vary by country and tier, so treat presets as starting points and edit them to match your actual bill.
