One of the best salespeople I ever worked with had a name for the annual renewal. He called it "poking the bear."
His point was simple. If a customer is happy, why wake them up once a year and ask them to decide all over again?
Annual plans have that cost. But they also bring a year of cash up front and stop the slow monthly leak. The question is how much discount that's worth. And the answer depends almost entirely on your churn.
How to use the annual discount calculator
- Enter your monthly price and monthly churn. If you don't know your churn, work it out with the Churn Rate Calculator first.
- Set the annual discount you're considering. "Two months free" is 16.7%.
- Add your annual renewal rate, the share of annual customers who renew each year. If you don't have one yet, start with a cautious guess.
- Add a cost of capital. That's what cash today is worth to you, such as your loan rate or the return you'd expect elsewhere.
- Pick a horizon of one to five years.
How the maths works
The year-one test comes from our guide to annual vs monthly plans. A monthly customer doesn't pay for twelve months on average, so compare the annual price with what they actually pay:
Expected months paid in year one = (1 − (1 − monthly churn)^12) ÷ monthly churn Break-even annual discount = 1 − (Expected months paid ÷ 12)
The multi-year test adds renewals and the time value of money:
Monthly plan value = Σ price × (1 − churn)^month ÷ (1 + monthly rate)^month Annual plan value = Σ annual price × renewal rate^year ÷ (1 + cost of capital)^year
The horizon break-even is the discount at which the two are equal.
A worked example
Take a $50-a-month subscription with 5% monthly churn.
The average monthly customer pays for (1 − 0.95^12) ÷ 0.05 = 9.19 months in year one. That's $460, not $600. So the year-one break-even discount is 1 − 9.19 ÷ 12 = 23.4%.
Offer "two months free" (16.7%, or $499.80 a year) and every annual sign-up is worth more to you in year one than the average monthly sign-up. You also collect the cash on day one.
Over three years, with 80% of annual customers renewing and a 10% cost of capital, the annual plan's lead gets bigger, because 80% renewal beats the 54% of monthly customers who are still around after twelve months.
How to read the result
The guide's advice is not to spend the whole break-even. The customers who choose annual plans are usually your most committed ones. Hand them the full discount and you're partly paying loyal people to do what they'd have done anyway.
Aim for roughly half to three-quarters of the year-one break-even. At 5% churn, that's about 12% to 18%.
For context, the guide found business software clustered at 15% to 25% off in October 2026, with "two months free" the most common figure. High-churn consumer apps went as deep as 44%.

Frequently asked questions
What is a normal annual subscription discount?
Most business software discounts annual plans by about 15% to 25%, and 'two months free' (16.7%) is the most common figure in the guide's October 2026 sample of 17 companies. Consumer apps with high monthly churn go deeper. Strava and Monarch both discount annual plans by about 44%.
Why does churn set the right annual discount?
Because a monthly customer only pays while they stay. At 2% monthly churn, the average customer pays for about 10.8 of their first 12 months, so the break-even discount is about 10%. At 10% churn they pay for about 7.2 months, so you can afford about 40% off and still come out ahead in year one.
Do annual plans increase churn at renewal?
Annual plans swap a small monthly decision for one big yearly one. Some customers who'd have kept paying monthly without thinking will cancel when the renewal email arrives. Reduce that by reviewing usage three months before renewal, sending a value summary before the reminder, and making the renewal amount and date clear.
Should I show the annual price as a monthly figure?
Most software companies do, for example '$17 per month billed annually' against $20 monthly. It makes comparison easy. Always show the total charged up front as well and when it's taken. Hiding the upfront amount invites complaints and refund requests, and in Australia, prices must not mislead.
How do I account for annual payments?
An annual payment is cash today but revenue over the year. Your books usually record it as income received in advance and recognize one-twelfth each month, so a $1,200 plan adds $100 to MRR. When you report GST depends on your accounting method. Check your setup with your accountant.
