How free trials become charges: the conversion, explained

The negative option model

Free trials run on a mechanism regulators call the negative option: the merchant charges you unless you take an action to stop it. You agree to the terms when you sign up, and those terms include a conversion date, a price, and a billing interval. If you do nothing, the charge happens.

The word “free” in marketing does not mean “no card required.” A trial with a card on file is the merchant’s insurance that anyone who stays past the trial is paying. Some services require the card up front; others convert a card already on file from an earlier purchase. Either way, the trial and the card are connected from the start.

What the rules require

The FTC’s 2024 amended click-to-cancel rule was vacated by the Eighth Circuit on July 8, 2025. The FTC’s March 2026 rulemaking notice describes that decision and discusses existing laws, including ROSCA for online negative-option transactions. Do not treat the vacated rule as a current universal cancellation requirement.

Find the actual trial terms before deciding what should have happened: the end date, price, renewal interval and cancellation method. Keep the receipt and cancellation record. An illustrative offer such as seven days followed by a monthly charge does not establish the terms of your own account.

The descriptor does not settle whether consent was obtained or whether a refund is owed. A missed reminder, a cancellation error and an unauthorized subscription need different evidence. Ask the merchant about the account event, and report suspected unauthorized activity to your issuer promptly.

What the first real charge looks like

When a trial converts, the charge posts at the billing interval you agreed to — usually the day the trial ends, with the merchant billing within a small window around it. The descriptor is the same one the subscription keeps forever after: APPLE.COM/BILL for App Store subscriptions, the streaming service’s own name for Hulu or Disney+, a processor prefix for smaller apps.

The amount is often a surprise even when the date is not. Trial conversions frequently land at the standard monthly price, but annual trials convert to the annual rate and promo trials convert to the full price. If the charge is bigger than the advertised trial price, the plan you converted into is the reason — check the fine print you agreed to rather than the marketing you remembered.

Handling a conversion you did not want

1. Find the conversion date Your trial email and the sign-up page both state when the free period ends and what bills after. If you cannot find it, the merchant is required to tell you.
2. Decide before the date, not after Check the actual cancellation deadline and process before the trial ends. Keep the confirmation rather than assuming the vacated federal click-to-cancel rule determines every subscription term.
3. Cancel through the billing source App Store trials cancel in Settings → Subscriptions; merchant-site trials cancel in the account page. A canceled trial should never convert.
4. If you were charged anyway Compare a later charge with the cancellation date, covered service period and confirmation. Ask the merchant to explain a mismatch. Report suspected unauthorized activity to the issuer promptly rather than waiting for a merchant response.
