Introductory Discount vs Renewal Cost: Calculate the First-Year Total
Quick answer: calculate promotional months and renewal months separately. First-year cost = promotional price × promotional months + renewal price × remaining months + fees. Then show the annual renewal cost on its own; averaging both can hide the price jump.
Worked example
A service offers 9 for the first three months, then renews at 24, with a 12 activation charge. First-year cost is `9 × 3 + 24 × 9 + 12 = 255`. The next full year is `24 × 12 = 288`, before any changed fee. Comparing 9 with another plan’s $20 is not enough because the time periods differ.
If you may cancel at month four, include the cancellation fee and ask whether the initial discount is clawed back. Do not assume a reminder email, refund, or renewal notice will arrive in time; use the written terms and set your own calendar.
The CFPB spending guidance supports reviewing several months of actual expenses. Use the annual cost savings calculator for the full first-year comparison and the budget builder for the renewal amount. This page is educational, not legal or financial advice.
Three numbers to report
- cash paid during the promotional first year;
- ordinary twelve-month renewal cost;
- cost if cancelled at the likely decision date.
The promotion is useful only if the service remains valuable at the renewal price. A low first month should not force a long subscription.
FAQ
Is the first-year price the true annual price?
It is the first-year cash total, not the recurring renewal price. Report both.
Should I include a free trial?
Include the zero-price months, then include the charge that begins after the trial and any required fee.
What if the renewal price is unclear?
Do not invent it. Mark the result unknown and check the current contract or merchant disclosure.
