Subscription Worth-It Calculator
Compare subscription charges with paying per use, then test lower usage and a possible price increase.

Your decision snapshot
Pay for the usage you expect, not the usage you hope for
A subscription spreads a fixed charge across actual use. Compare a realistic month with a quieter one before deciding. If convenience or access has value beyond the counted uses, consider that separately; this tool compares money costs, not every personal benefit.
Use comparable alternatives: the same class length, quality, features or service level. If the alternative has additional fixed fees, this simple per-use comparison will understate its cost.
Worked example: $15 a month versus $3 a visit
At eight uses per month for 12 months, the subscription costs $180 and the alternative costs 8 × 12 × $3 = $288. The subscription saves $108. Break-even is $180 ÷ $3 ÷ 12 = five uses per month.
At three uses per month, the alternative costs $108 while the subscription still costs $180. Pay per use costs $72 less. At five uses per month, both cost $180. At zero uses, subscription cost per use is undefined, not zero.
Methodology and formulas
Billing is charged in full at the start of each period; there is no prorated refund. Bills = ceiling(months × billing periods per month). Factors are 52/12 for weekly, 1 for monthly, 1/3 for quarterly and 1/12 for annual. One-time access uses one charge. Weekly billing uses a standardized 52-week year, not an exact calendar schedule.
Subscription total = bills × price + setup + entered cancellation fee. Alternative total = monthly uses × months × alternative price per use. Subscription cost per use = subscription total / expected total uses.
Break-even uses per month = subscription total / alternative price per use / months. This is an average; use a higher whole-number count when visits cannot be fractional. If the alternative is free, there is no paid-use break-even unless both costs are zero. No-use cost per use is shown as not applicable.
The reduced-usage scenario holds subscription charges fixed. The price-increase scenario applies the percentage to every subscription bill and keeps setup/cancellation fees unchanged. When an increase is entered, a combined low-use/high-price scenario is also shown. Annualized cost scales the full horizon cost by 12/months and includes one-off fees; it is not a recurring renewal price. One-time access is not annualized.
For a partial annual commitment, the whole annual bill is counted. Check the contract yourself: minimum terms longer than a billing period, cancellation notice, pauses, trial periods and unused credits are not inferred.
Questions people ask
Should I enter the annual price or the monthly equivalent?
Enter the actual price charged for the selected billing frequency. Choose annual and enter the full annual charge for an annual plan.
What happens if I cancel early?
Full billed periods are still counted. Add an expected cancellation fee if it applies. Refunds and minimum contract terms are not automatically modeled.
How do I compare one-time access?
Choose one-time access and select the period during which you expect to use it. The purchase is counted once, plus entered setup and cancellation costs. No annualized cost is shown.
Is break-even usage a recommendation to use more?
No. It is a comparison threshold. Increasing usage just to justify a fee may not fit your needs or time.
What is included — and what is not
Included: full billing charges within a standardized evaluation period, setup, entered cancellation fee and a per-use alternative. Excluded: taxes unless included in prices, refunds, free trials, minimum contract terms beyond billing periods, pauses, unused credits, alternative fixed fees, time value of money and non-monetary benefits. Verify actual billing dates and contract terms.
