About Subscription Renewal Date Calculator

Billing cycle length determines both the renewal date and the true annual cost. A four-weekly cycle bills 13.04 times a year rather than twelve, so a 12.99 charge costs 169.39 annually instead of 155.88 - an 8.7% premium that is easy to miss on a monthly-looking subscription.

Formulas

Next renewal

renewal = last renewal + cycle length

Annual cost

Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why is four-weekly more expensive than monthly?

Because there are 13 four-week periods in a year, not 12. The headline price looks monthly but bills an extra time annually.

Do annual plans always save money?

Usually 15-20%, but they remove the option to cancel mid-term, so the saving is really a discount for locked-in commitment.
