The credit-card box decides your trial conversion
Requiring a card up front roughly triples free-trial-to-paid conversion – about 31% vs 9%. Why less friction isn't always the win.
Requiring a credit card up front is the single biggest lever on free-trial conversion: opt-out trials that ask for a card convert to paid at roughly 31%, versus about 9% for opt-in trials with no card – nearly 3x from the same traffic.
That gap comes from ChartMogul's 2026 SaaS Conversion Report, which looked at 200 software products. The takeaway isn't "always demand a card" – it's that the card field does more than add friction. For a trial, it quietly filters for people who actually intend to buy.
If your instinct is to strip every barrier off your trial signup to push the numbers up, you may be halving your paid conversions instead. Worth testing the opposite on your own funnel before you assume less friction wins.
