Should you shorten your free trial?

Decide whether a shorter free trial would raise conversions for your product, and test it.

Shortening your free trial, from 30 or 14 days to 7, for instance, is meant to create urgency and shorten your sales process. It works when new users can reach the first useful result in a day or two. The research is mixed, so treat a shorter trial as something to test against your current length, not a rule. Products that need data imports or team setup, like a CRM, may need longer.

How to do it

  1. Find your time to value. Pick the one action that predicts a paying customer (first report built, first teammate invited, first integration connected). Look at how many days after signup your paying customers took it.
  2. Compare that to your trial length. If most converters hit the action in their first three days, a seven-day trial leaves enough time. If it takes ten days, shortening will cut off people who were about to succeed.
  3. Fix onboarding before the calendar. A short trial only works if users reach that action fast, so move it into the first session.
  4. Split new signups at random between your current length and a shorter one. Run both until each group has enough signups to be meaningful for your volume.
  5. Judge the test on paying customers and their retention a month or two later, not on trial-end conversion alone. Longer trials can convert later, after the trial has ended.
  6. Email the user on the day before the trial ends with a clear next step. Offer one extension to people who reached the key action and need more time, and none to people who never started.

Examples

  • Semrush offers a seven-day trial. Its pricing page says: "Try Semrush free for seven days. Cancel anytime."
  • What the field uses. ChartMogul's SaaS conversion report, a survey with 200 responses run in January 2026, found 14 days the most common trial length (62% of products), followed by 7 days (14%) and 30 days (14%). That shows what companies use, not which length converts best.

When it backfires

  • The evidence points both ways. A 2025 randomized field experiment with 680,588 users of one global SaaS company, in a freemium model, found that longer trials significantly increased free-trial adoption and delayed conversion, with no significant effect on immediate conversion. Separately, RevenueCat analyzed 17,000+ consumer subscription apps (data from August 2025 to July 2026) and found a 42.5% median trial conversion rate for trials of 17 or more days versus 25.5% for trials of four days or less. Those are apps, not B2B tools, and the comparison is not a controlled test.
  • Complex products need time. If setup involves importing data or inviting a team, a shorter trial can end before the product has had a fair try.
  • Long evaluation cycles. Buyers in B2B often need approval, security review or a second opinion. A seven-day clock can end before the decision does.
  • Billing law. If the trial turns into a paid plan automatically, the US Restore Online Shoppers' Confidence Act applies. You must clearly disclose all material terms before getting billing information. You need express informed consent before charging. And you must provide simple ways to stop recurring charges. The FTC's click-to-cancel rule was vacated by the Eighth Circuit on July 8, 2025, but that ruling did not affect this law.
  • Fake urgency. A countdown that resets when the user returns is a trick, not a short trial. Keep the end date real.

Questions people ask

How long should your free trial be? There is no universal answer. Match the length to how quickly your users reach the first useful result, then test one shorter and one longer variant.

Should you offer a free trial extension? It is common to offer one on request. Give it to engaged users who ran out of time, not to everyone who asks.
