Annual vs monthly plans: when is the yearly plan actually cheaper?

Quick answer

A yearly plan is cheaper if you will use the service for more months than the break-even point, which is the yearly price divided by the monthly price. If a yearly plan costs 8.25 times the monthly price, you need at least 9 months of use to come out ahead. If you are not sure you will keep the service that long, monthly billing is the safer choice.

Yearly plans are often advertised as a discount, and they frequently are. But a discount only helps if you use what you pay for. The right choice depends on how many months you will really use the service, not on the label “best value”.

The break-even formula

Two numbers are enough: the monthly price (M) and the yearly price (Y).

Break-even months = Y ÷ M

This is the number of months of monthly billing that would cost the same as one year on the yearly plan. If you expect to use the service for longer than that, the yearly plan is cheaper. If you expect to use it for fewer months, monthly billing is cheaper, because you can stop paying at any time.

Two related figures are useful:

A worked example (hypothetical numbers)

These prices are invented for illustration and are not any real service’s prices. Suppose a service charges $12 per month or $99 per year.

Hypothetical example: $12 per month vs $99 per year

3$36$99Monthly
6$72$99Monthly
8$96$99Monthly (just)
9$108$99Yearly
12$144$99Yearly

The lesson: the same discount can be great or wasteful. For someone who uses the service all year it saves $45. For someone who will drop it after four months it costs $51 more than paying monthly ($99 minus $48).

What the formula does not capture

Refunds, cancellation and price changes

The cheapest-looking plan is not cheap if you cannot get out of it. Before you pick the yearly option, check three things in the service’s terms and billing page:

  1. Refund policy. Some services refund the unused part of a yearly plan, some refund only within a short window, and some do not refund at all. Rules also differ by country and by where you bought it (the service itself, or an app store).
  2. What cancelling does. Usually cancelling stops the next renewal but keeps access until the paid period ends. Confirm this, because it decides whether you can cancel right after buying and still use the full year.
  3. Renewal price. Introductory yearly prices sometimes rise at renewal. The price shown at sign-up is not always the price you will be charged next year.

Trials add another trap: some free trials convert straight into a yearly plan, so the first charge is the whole year rather than one month. Read the confirmation email, and see our free trial reminder guide for how to avoid that.

Never be surprised by a yearly renewal

A yearly plan has one weakness: you only see the charge once a year, so you forget it exists. The fix is to record the renewal date when you buy and set a reminder well ahead of it, for example two weeks before, so you have time to decide whether to keep, switch to monthly or cancel.

A simple way is to add the plan to a list that shows both monthly and yearly cost, so a $99 yearly plan appears as $8.25 a month next to your other subscriptions. If you do not have a list yet, start with how to track all your subscriptions in one place, or run the 15-minute audit to find yearly charges you forgot.

Doing this with SubTrack Pro

SubTrack Pro is a free Chrome extension where you add each subscription with its billing cycle and next payment date. It shows monthly and yearly totals, so you can see what your yearly plans add up to, and sends reminders 3 days before, 1 day before and on the day of a payment. For a yearly plan, that is a short window, so pair it with an earlier calendar reminder if you want time to compare alternatives.

It has no account, no ads and no cloud sync, and your data stays in your browser. It does not cancel plans or connect to your bank, so you still make the switch or cancellation yourself.
