Trust Badge ROI Estimator
Estimate the conversion lift and revenue from adding trust badges.
A 8% lift from security and authority badges would add roughly $4,608/month, $55,296 a year, for a near-zero-cost change. Place them where data is entered, not just in the footer, and A/B test to confirm the lift.
The lift is an assumption until you test it. Badges help most on unfamiliar brands and at the moment of entering payment or personal data.
About this calculator
Security seals and authority logos are one of the cheapest changes available to a form or checkout page, but the size of the payoff varies enough that it's worth modeling before you spend design time on it. This estimator takes your visitor volume, current conversion rate, and an expected relative lift, and turns it into projected monthly and annual revenue.
How to use it
- Enter monthly visitors to the form or checkout you're assessing and your current conversion rate.
- Enter an expected relative lift from adding trust badges (commonly 3-15%, test to confirm your own figure) and the value of one conversion.
- Read the projected new conversion rate, extra conversions per month, and the monthly and annual revenue lift.
Methodology
Projected conversion rate is current conversion rate × (1 + expected lift ÷ 100), a relative, not absolute, lift applied to your baseline rate.
Extra conversions per month is visitors × (projected rate − current rate). Monthly revenue lift is extra conversions × value per conversion, and the annual figure is simply ×12.
The expected lift is an input you supply, not something the tool measures, badges tend to help more on unfamiliar or newer brands and specifically at the moment of entering payment or personal data, where uncertainty is highest.
FAQ
It varies widely by brand familiarity, industry, and where the badges are placed, published lifts commonly range from single digits to the mid-teens as a relative improvement. A well-known, established brand typically sees less lift than a newer or lesser-known one, since trust is already established through other signals.
Yes, badges placed at the actual point of data entry (near the card field, next to the submit button) outperform the same badges shown only in the footer, since the goal is reducing hesitation at the exact moment it occurs, not just displaying credentials generally.
Yes, this estimator gives you the business case to justify running the test, but the lift figure is an assumption until validated. A/B test badge placement against a control to confirm both the direction and size of the effect for your specific audience.
