🔁 Subscription Cost & Usage Calculator
Subscriptions are easy to sign up for and easy to forget. List yours here to see the annual total, the monthly equivalent, what each one costs every time you actually use it, and which renewal date arrives next.
A cost and usage calculator for figures you enter yourself. It does not recommend cancelling anything and it is not financial advice.
Your subscriptions
Add up to 20. Only the cost and billing frequency are needed. Add how often you use each one and the cost per use is worked out too.
Subscription names, costs, usage and renewal dates stay in this browser. Nothing is saved to your device by this page, nothing goes into the web address, and none of it reaches analytics.
How cost per use is calculated
- Each cost is converted to an annual figure with the same multipliers used across this site:
weekly × 52,fortnightly × 26,every 4 weeks × 13,monthly × 12,quarterly × 4,yearly × 1. - The monthly equivalent is
annual ÷ 12. - Usage is annualised as
uses per month × 12, and cost per use is thenannual cost ÷ annual uses. - If you record zero uses, no cost per use is shown at all. Dividing by zero produces infinity, which is not a number anyone should see in a results table — the row simply says no uses were recorded.
- Days to renewal counts whole days from today at local midnight.
- There is deliberately no threshold anywhere in this tool. It never marks a subscription as bad value, because no single cost-per-use figure is right for everyone.
Choose which subscription to review first
The calculator does the arithmetic. If you have a long list and no obvious starting point, this optional wheel picks one for you — it does not know your figures and it is not suggesting you cancel anything.

A worked example
A streaming service at £12 a month that you watch 12 times a month: that is £144 a year (£12 × 12), 144 uses a year (12 × 12), and so £1.00 per use.
Now a second one, also £12 a month, that you watch twice a month. Identical cost — £144 a year — but 24 uses, which is £6.00 per use. Same price on the bank statement, six times the cost per viewing.
The tool stops there. £6 per use might be perfectly reasonable for something you genuinely look forward to, and £1 per use can still be money wasted on something you leave running in the background. It shows you the arithmetic; the judgement is yours.
Frequently asked questions
Does this tell me what to cancel?
No. It has no idea what any subscription is worth to you, so it surfaces the arithmetic and stops there. You will not find a "cancel this" flag anywhere in the results, because that would be a guess dressed up as a recommendation.
Why is there no benchmark for a reasonable cost per use?
Because an honest one does not exist. A £6-per-use subscription can be excellent value for something you look forward to, and a £0.50-per-use one can still be money wasted. Inventing a universal threshold would make the tool feel authoritative while being wrong for most people.
What happens if I record zero uses?
The row shows that no uses were recorded and leaves cost per use blank. Dividing by zero gives infinity, and no result table on this site will ever display that.
Can I sort by which renewal is coming up next?
Yes. The sort control offers annual cost, cost per use, renewal date, least used first, and name. The soonest upcoming renewal is also shown as a headline figure above the table.
Are my subscription names stored anywhere?
No. This page saves nothing to your device. Everything is held in the page while it is open, which is why the copy and CSV options exist for anything you want to keep.
Is the CSV safe to open in a spreadsheet?
Yes. Text beginning with =, +, -, @, a tab or a carriage return gets a leading apostrophe so it cannot be treated as a formula, while calculated figures stay as plain numbers.
How the wheel works
How does the wheel pick a result?
The wheel selects a result at random before the animation starts, then calculates the exact rotation needed to land that result under the pointer. The displayed result always matches where the wheel visually stops.
Is every option equally likely?
Yes. Every option has an equal chance of being selected, using your browser's built-in random number generator with no weighting or bias.
Can I edit the options?
Yes. Add, remove, or edit any option using the text area on the right. Changes take effect on your next spin and stay only for your current browser session.
