How to read the result
The cheaper path is the one with the lower total over the months you entered. That is a cash comparison, not a verdict on features or lock-in.
Calculated facts
Totals, differences, and break-even figures come only from the values on this page. They describe the math, not what you should do.
Decision factors
Fit, risk, time, quality, and personal constraints stay outside the calculator. A cheaper path can still be the wrong path for those reasons.
Methodology
Each price is multiplied by the number of periods in a year (52 weeks, 12 months, 4 quarters, or 1 year) to get an effective annual cost. Horizon cost charges whole billing cycles: a prepaid annual plan still costs a full year if you leave after a few months, unless you shorten the model another way. For a monthly-versus-annual pair, months to break even is annual price divided by monthly price.
Assumptions
- Prices do not change during the horizon.
- Unused prepaid months have no refund unless you model that by shortening months kept.
Examples
Software seat
$20 per month is $240 a year. $192 billed annually is $16 a month effective. If you stay 12 months, the annual plan costs $48 less.
Short trial of an annual plan
If you cancel after 3 months, a $180 annual charge is $60 per used month, which is worse than a $18 monthly plan.
How to use it
- Enter each plan’s billed price and billing period.
- Set how many months you expect to keep the service.
- Read effective monthly and annual cost, then the total over your horizon.
Limits
- Family plans, unused seats, and usage caps are not modeled.
- Promotional first-year pricing should be entered as the real second-year price if you will keep the plan.
Questions
When does an annual plan win?
An annual prepaid plan costs less only if you keep the service long enough to use the prepaid months. If a $120 year is compared with $12 a month, you need 10 months before the annual price is cheaper. Cancel at month 4 and the monthly plan cost less.
Does this include sales tax or intro rates?
No. Enter the price you will actually be billed after any trial. Tax and currency conversion are outside the model.
Can I compare two different services?
You can put any two prices on the same time scale. The math does not judge whether the products are equivalent.
