Gravity
Subscription cost-per-use calculator
A subscription’s real cost isn’t its price, it’s its price divided by how often you actually use it. Enter each subscription’s monthly cost and how many times you use it per month, and this free calculator shows your cost per use and flags the ones that aren’t earning their keep. Everything runs in your browser, nothing is saved.

Why cost per use beats the sticker price
A $9.99/month app sounds cheap, but if you open it once a month that’s $10 per use, more expensive than a $16 service you use twice a week. Cost per use is the fastest way to see which subscriptions to keep, which to downgrade, and which to cancel before the next renewal. Once you know your number, add up your full monthly total and follow a step-by-step cancellation guide for anything that isn’t worth it.
Frequently asked questions
How is cost per use calculated?
Cost per use is the monthly price divided by how many times you use the subscription that month. A $16 streaming plan you watch 8 times a month costs $2 per use; a $40 gym you visit twice costs $20 per use.
What counts as a good cost per use?
It depends on the value you get, but as a rule of thumb this tool flags anything under about $2 per use as good value, $2 to $6 as okay, and over $6 (or unused) as worth reconsidering.
Is this calculator free and private?
Yes. It's completely free with no sign-up, and everything runs in your browser, nothing you type is saved or sent anywhere. It's made by Gravity, a private subscription manager app for iPhone.
