Trial to Paid Conversion

Updated over 3 months ago

The Trial‑to‑Paid Conversion Rate is the percentage of users who finish their free trial and become paying customers. Monitoring this metric helps you:

  • Gauge onboarding quality and product‑market fit

  • Measure the effectiveness of trial messaging and paywall timing

  • Optimize marketing spend by focusing on channels that deliver high‑intent trials


1  | How Grow Slash Calculates the Trial‑to‑Paid Conversion Rate

Core formula
Trial‑to‑Paid Conversion Rate = (Number of Trials Converted to Paid ÷ Total Trials) × 100

Grow Slash evaluates each trial individually, mirroring the way platforms such as Stripe handle trial periods:

  1. Unique conversion window – Every user’s trial starts when they sign up and ends on their own trial‑end date.

  2. Real‑time checks – The instant a trial ends, Grow Slash determines whether the user:

    • ✅ Made a successful payment (converted)

    • ❌ Did not pay or cancelled (churned)

  3. Live update – The overall conversion rate refreshes continuously as new trials reach their end, so your dashboard always shows the latest performance.


2  | Examples

2.1  Single‑day view

If 100 trials ended yesterday and 60 of those users converted, the rate for that day is: (60 ÷ 100) × 100 = 60 %

2.2  Merging multiple days

Suppose you look at a three‑day window:

Date

Trials ended

Conversions

1 May

40

26

2 May

30

15

3 May

50

32

Combined totals: 40 + 30 + 50 = 120 trials, 26 + 15 + 32 = 73 conversions.
Trial‑to‑Paid Conversion Rate for 1–3 May = (73 ÷ 120) × 100 ≈ 60.8 %

Because Grow Slash calculates on each user’s exact trial‑end timestamp, you can select any date range—daily, weekly, monthly—and the platform instantly aggregates the underlying events to give the blended rate.


3  | Key Considerations

  • Rolling metric – Results update live; choose any time span to evaluate recent campaigns or onboarding tweaks.

  • Consistent logic – The same individual‑window method applies whether you view a single day or an entire quarter.
