How to calculate trial to paid conversion rate
Trial to paid conversion rate is the defining metric of a free-trial product-led motion. It measures how effectively your trial turns interested users into paying customers.
Conversion is driven overwhelmingly by whether users reach value during the trial. Activation and time to value are the upstream levers that move this rate more than any billing tactic.
- Converted / trials The formula
- Activation-driven Value during trial
- Opt-in vs opt-out Trial type shifts it
Short answer
Trial to paid conversion rate is the share of free trials that become paying customers. Divide the number of trials that converted to paid by the total number of trials started in the period, then multiply by 100. If 250 of 1,000 trials converted, the rate is 25 percent. It is a core product-led growth metric driven heavily by activation and time to value.
Step by step
Count trials started
Count the free trials started in the period as the denominator. Decide whether to count all trials or only qualified ones.
Count conversions to paid
Count the trials that converted to a paying subscription within the trial window or shortly after.
Divide converted by trials
Trial to paid conversion rate equals conversions divided by trials started, times 100.
Segment by activation
Break the rate out by whether users activated during the trial. Activated trials convert far higher, which shows where to focus onboarding.
Worked example
In the month, 1,200 users started a free trial. 300 converted to paid. Trial to paid conversion = 300 / 1,200 = 25 percent.
Splitting by activation: of 500 users who reached the value milestone, 240 converted (48 percent), while of 700 who did not activate, only 60 converted (about 9 percent). Activation is the dominant driver, so improving onboarding to lift activation would raise overall conversion most.
How Ardovo handles it
Ardovo can track trial to paid conversion tied to activation and time to value, so you see what actually drives it. Rook flags trials that have not activated partway through, prompting intervention while there is still time to convert them.
Frequently asked questions
What is the trial to paid conversion rate formula?
Trials that converted to paid divided by total trials started in the period, times 100. Segment it by whether users activated during the trial, since activated trials convert far higher than unactivated ones.
What is a good trial to paid conversion rate?
It varies by trial type: opt-in free trials (no card required) often convert 15 to 25 percent, while opt-out trials (card required) convert much higher, 40 to 60 percent, because they pre-qualify intent. Compare within your model.
How do I improve trial to paid conversion?
Focus on activation and time to value, since users who reach value during the trial convert far more. Streamline onboarding, guide users to the aha moment quickly, and intervene with trials that have not activated partway through.
