Compare monthly vs annual billing in seconds
Subscriptions are priced to look small. "$15 a month" sounds trivial until you multiply it out to $191.88 a year - and a service billed weekly can be sneakier still. This calculator takes any amount and cadence and instantly shows the true monthly, yearly, and even per-day cost, so you can compare services on equal footing and see the real number you are committing to.
It is especially useful when a provider offers both a monthly and an annual plan. Punch in each one, compare the annualized totals, and the discount for paying yearly becomes obvious. Sometimes the annual plan saves a meaningful amount; sometimes the "deal" barely moves the needle and the monthly plan keeps your options open. Either way you decide with numbers, not marketing.
Is it actually worth it?
The cost-per-use panel answers the question that really matters: what does each use cost you? Enter how many times you use the service in a billing period, and the calculator divides the price by that usage. A streaming service you watch twenty times a month is a bargain; a premium app you open twice is quietly expensive. When the cost per use climbs past what you would happily pay a la carte, that is your signal to cancel.
Once you have decided what to keep, track it all in theSubscription Tracker and watch renewals on theRenewal Calendar. This calculator saves nothing and runs entirely in your browser - it is a fast, private scratchpad for the "keep or cut" decision.
Frequently asked questions
How is the annualized cost calculated?
The calculator normalizes whatever cadence you pick to a common baseline. Weekly is multiplied by 52, monthly by 12, quarterly by 4, and yearly by 1 to get the yearly cost, which is then divided down for the monthly and per-day figures.
What is cost per use?
It is the price of one billing period divided by how many times you actually use the service in that period. A $15/month app used twice a month costs $7.50 per use - a quick reality check on whether a subscription earns its keep.
Does this save anything?
No. The cost calculator is a scratchpad - it runs entirely in your browser and stores nothing. Use the Subscription Tracker if you want to keep a saved list.
