Adding a discounted annual plan next to the monthly plan raised proceeds per user by 80% and trial conversion by 22%. Preu AI, a university entrance exam prep app in Chile, ran this A/B test on its paywall. The result was published as a Superwall case study.

## Result

**+80% proceeds per user; +22% trial conversion**

- Proceeds per user: up 80% in the variant.
- Trial conversion rate: up 22%.
- Plan mix (how many picked annual) was not shared.

## Control

The paywall offered one monthly plan with a "Try Free" button.

## Variant

The paywall kept the monthly plan and added an annual plan, described as priced at 60% of the monthly price. Exact prices were not shared.

## Why it likely won (our reading)

- The annual price likely made the monthly plan look expensive. That pushed buyers toward the bigger plan.
- Exam prep runs for months, so a yearly commitment fits how students actually use the app.
- Giving people a choice of plans, not just one, may have made more of them buy.

## Caveats

Sample size, test length, exact prices and confidence were not shared. Superwall sells the paywall testing tool used here and published this result, so it may lean positive.

## How to run this test

- Hypothesis: If we add a discounted annual plan next to our monthly plan, then proceeds per user will rise because the annual price makes the yearly commitment look like the better deal.
- Primary metric: Proceeds per user
- Guardrail: Trial-to-paid conversion
- Guardrail: Refund rate on annual plans
- Guardrail: Monthly plan conversion
- Who should test it: Apps with a single plan and a use case that lasts months, like study or fitness goals. It may not fit apps people only need for a few weeks.
