Turn a provider's actual billing schedule into estimated 30-, 90-, and 365-day cash exposure. This is especially useful when a low “per month” number comes from prepaid, 21-day, 28-day, multi-month, or introductory billing.

Calculate the cash impact of a billing schedule
Enter the amount a program charges and how often it renews. The calculator estimates how much cash that schedule would charge within 30, 90, and 365 days if the same billing pattern continued.

How the calculation works
Enrollment is treated as the first charge at day zero. Later charges are placed at the billing interval you enter. A renewal that falls exactly on the end of a 30-, 90-, or 365-day horizon is treated as the next period rather than part of that horizon. Calendar-month billing is normalized using 365 ÷ 12 days per month, while day- and week-based billing keeps its actual cadence.
This tool models billing only. It does not know whether a provider will change prices, pause a subscription, alter a prescription, require labs, add taxes or fees, or stop billing after a fixed commitment. Enter the full charge that applies to the plan and reconfirm checkout and renewal terms.
What to copy from a provider before calculating
Use the numbers shown in the checkout or formal billing terms whenever possible—not only the lowest price in an advertisement. Record the first charge, the normal renewal charge, and the exact renewal interval. If an introductory first charge covers a different period, turn on the first-period option in the calculator.
Why billing cadence changes the real comparison
“$99 per month” can describe very different cash commitments. One program may charge $99 each calendar month, another may charge every 21 or 28 days, and another may require hundreds or thousands of dollars upfront while displaying a monthly equivalent. Comparing the actual charge schedule makes those differences visible.
How to use the result
Treat the output as a billing estimate, not a personalized quote. Compare it with the provider's cancellation deadline, refund rules, renewal terms, included services, pharmacy disclosures, and any costs that sit outside the program price. The calculator does not assume that two programs provide equivalent medication, clinical care, labs, shipping, or state access.
