Enter the monthly and annual price to see how many months it takes for the annual plan to pay off, the effective monthly price, and the free months. Then switch tabs to total all your subscriptions by month, year, and day.
Is an Annual Plan Worth It? The Break-Even Math
Many services price an annual plan below twelve monthly payments, but you pay the full year upfront. The question is whether you will keep the service long enough to come out ahead. The answer is the break-even month: the annual price divided by the monthly price, rounded up.
This calculator turns that into a plain rule: cancel before the break-even month and monthly billing costs less; stay past it and the annual plan costs the same or less. It also shows the effective monthly price, how many months are free, and a chart of total paid over time so you can see where the lines cross.
The second tab adds up everything you pay for. Enter each subscription with its billing cycle and the tool converts it to a monthly amount, then shows your monthly, yearly, and per-day cost. Mark any subscription as a cancel candidate to see how much a clean-up would save per year.
When to Run the Numbers
Signing up for streaming, learning, or app plans
Before you pick a plan, check how many months you need to stay for the annual price to beat monthly billing, and how many months are effectively free.
Reviewing what you pay every month
List all your streaming, music, cloud storage, and AI subscriptions in one place to see the monthly total, the yearly total, and the daily cost. Then check what cancelling a few would save.
Choosing software or SaaS billing
For design, project management, or AI tools, enter how long your project will last. The result shows whether to prepay for a year or stay month to month.
Memberships, gyms, and coworking
Compare paying month to month with paying for the year on gym, coworking, or club memberships, using your own planned length of stay.
Compare Two Plans in Four Steps
- On the Annual vs Monthly tab, enter the monthly price and the annual price. If you don't know the annual price, tap a preset such as “2 months free” to estimate it.
- Set how many months you plan to use the service (1 to 36) with the slider or the number box.
- Read the result: which plan costs less, by how much, the break-even month, the percent off, and the free months. The chart shows total paid over time.
- To see everything you pay for, open the Subscription Total tab. Add each service with its price and billing cycle, then check the monthly, yearly, and daily totals and any savings from cancelling.

What the Calculator Assumes
- Effective monthly price: the annual price divided by 12, which is handy when you track a budget by month.
- Billing cycle conversion: weekly × 52 ÷ 12, every 3 months ÷ 3, every 6 months ÷ 6, yearly ÷ 12.
- No refunds: the annual payment is treated as non-refundable if you cancel early. If your provider refunds unused months, annual is less risky than shown.
- Fixed prices: the prices you enter are assumed to stay the same. Price increases, free trials, and one-time promotions are not modeled, so use an average monthly price if the price changes.

Example Break-Even Months at Different Annual Discounts
These rows are worked examples using the formulas above. They are not quotes from any provider.
| Monthly price | Annual price | Discount | Saved over 12 months | Break-even |
|---|---|---|---|---|
| $10.00 | $100.00 | 2 months free (16.7%) | $20.00 | 10 months |
| $15.00 | $144.00 | 20% off | $36.00 | 10 months |
| $20.00 | $180.00 | 25% off | $60.00 | 9 months |
| $50.00 | $510.00 | 15% off | $90.00 | 11 months |
Tip: After you choose a plan, put the renewal date on your calendar a week or two ahead. An annual plan that renews automatically after you stopped using it can wipe out the savings.
What the Break-Even Number Doesn't Cover
Price is only part of the decision. Check these points before you commit to a year.
Use the yearly total to rank what to cancel
A few dollars a month feels small, but the yearly and 10-year totals can be large. Looking at the cost per day makes it easier to ask whether you would pay that every day for the service.
Paying a year upfront affects your cash flow
An annual plan means one larger charge. If several annual renewals fall in the same month, that month's bill can be big. You may want to prepay only the services with the largest savings.
Billed in another currency
If a service charges in a currency other than USD, each monthly charge can come with a different exchange rate and a possible foreign transaction fee from your card issuer. An annual plan is converted once. Check your card's terms for the exact fees.
Changing plans in the middle of a term
Upgrading or downgrading during an annual term works differently at each provider. Some credit the unused time, others do not. Read the billing terms before you prepay, especially if you might switch plans.
Mistakes That Make Annual Plans Cost More
Forgetting that an annual plan auto-renews
You prepay for a year, stop using the service, and the renewal charge arrives twelve months later. The savings from the discount are gone, and then some.

Choosing annual for the discount alone
A line like “2 months free” makes annual look like an easy win. But if you cancel after four months, you have paid for twelve and the monthly plan would have cost less.
💡 See the solution▼
Not knowing your total subscription spend
Small monthly charges pile up, and with different billing dates and cycles it is hard to know the total. Services you rarely use keep billing.
💡 See the solution▼
Having several annual renewals land in one month
Switching everything to annual billing to save the most can put several large charges in the same month and strain your checking account.

Assuming you will get a refund for the unused months
Many providers do not refund the remaining months when you cancel an annual plan. If you assumed they would, the unused time is simply lost.

Break-Even and Billing FAQ
Q.Is an annual subscription cheaper than paying monthly?
A. Only if you keep it long enough. The annual price is a single upfront payment, so it costs less than monthly billing only once you reach the break-even month. Enter both prices and the number of months you expect to use the service, and the calculator shows which plan costs less and by how much.
Q.How do I calculate the break-even point for an annual plan?
A. Divide the annual price by the monthly price and round up. For example, $120 per year versus $12 per month gives 10 months. If you use the service for 10 months or longer, the annual plan costs the same or less. If you might cancel sooner, monthly billing is the cheaper choice.
Q.How does the calculator work out “free months” on an annual plan?
A. It uses 12 minus the annual price divided by the monthly price. With $10 per month and $100 per year, 100 ÷ 10 = 10, so you pay for 10 months and get 12: 2 months free, or about 16.7% off. If you don't know the annual price, the presets (2 months free, 15% off, 20% off, 25% off) fill in an estimate from your monthly price.
Q.How does it compare plans when I plan to stay longer than 12 months?
A. It assumes you start on the annual plan and renew it every full year. For the leftover months after the last full year, it picks the cheaper of another annual payment or monthly payments. You can test up to 36 months, and the chart shows total paid over time for both plans.
Q.How does the subscription total tab convert different billing cycles?
A. Each subscription is converted to a monthly amount: weekly prices are multiplied by 52 and divided by 12, every-3-months prices are divided by 3, every-6-months prices by 6, and yearly prices by 12. The tab then shows your monthly total, yearly total, cost per day (yearly total ÷ 365), and 5-year and 10-year totals.
Q.Does the calculator account for refunds if I cancel an annual plan early?
A. No. It assumes the annual payment is not refunded, which is the cautious case. If your provider refunds the unused months of an annual plan, the real risk of choosing annual is lower than the calculator shows, so annual would pay off earlier. Check the provider's cancellation and refund terms before you pay.
Q.What if the monthly price is discounted for the first few months, or taxes apply?
A. Enter the average monthly price you expect to pay over your whole planned period. Add up what you would pay in total, divide by the number of months, and use that figure. Enter prices as they appear on your bill, including sales tax if it is charged, so both plans are compared on the same basis.
Q.Are my entries sent anywhere, and do I need an account?
A. No account or install is needed. The calculations run in your browser and your entries are not sent to our servers. To pick up where you left off, the tool saves your entries in your browser's local storage on this device. Clearing your browser data removes them.
