Sales Funnel Trial to Paid Calculator
Estimate how many paid customers, how much revenue, and your cost per paid customer from trial signups, conversion rate, pricing, and acquisition cost.
Overview
The Sales Funnel Trial to Paid Calculator helps you estimate how many paying customers your trial funnel may produce and what that could mean for revenue. Enter your trial signup volume, trial-to-paid conversion rate, monthly price, acquisition cost, revenue period, and expected retention to get a practical funnel estimate.
How it works
The calculator starts with your trial signups and applies the trial-to-paid conversion rate to estimate paid customers. It then applies your retention percentage to estimate how many converted customers remain active over the selected period. Gross revenue is calculated as retained paid customers multiplied by monthly price and the number of months. Acquisition cost is based on trial signups multiplied by cost per trial, and net revenue subtracts that cost from gross revenue.
How to use this calculator
- 1Enter the number of trial signups for the period you want to measure.
- 2Add your expected or historical trial-to-paid conversion rate.
- 3Enter the average monthly price paid by a converted customer.
- 4Input your average cost to acquire one trial signup.
- 5Choose how many months of revenue to include.
- 6Review the estimated paid customers, revenue, and acquisition efficiency.
Example Calculation
Trial signups
1000
Trial to paid conversion rate
12%
Monthly price per customer
$49
Cost per trial signup
$20
Revenue period

Customer retention over period
80%
Estimated paid customers
120
With 1000 trial signups, a 12% trial-to-paid rate, a monthly price of 49, and 80% retention over 12 months, the funnel would estimate about 120 paid customers, roughly 56448 in gross revenue, and a cost per paid customer of about 166.67.
Frequently asked questions
What does this calculator estimate?
It estimates how many trial users may convert to paid customers, the revenue they may generate, and the acquisition cost tied to those conversions.
What is a good trial-to-paid conversion rate?
A good rate depends on your industry, pricing, product complexity, and traffic quality. This calculator is most useful for comparing scenarios using your own benchmarks.
Why is retention included?
Retention affects how much revenue converted customers actually generate over time. Lower retention usually reduces total revenue from the same number of conversions.
Does this calculator include churn month by month?
No. It uses a simplified retention percentage across the full period rather than modeling churn in each month.
Should I use monthly price or average revenue per account?
Use the figure that best represents what a typical converted customer pays each month. If customers are on mixed plans, an average value can be more realistic.
Is cost per paid customer the same as CAC?
It is a simplified version based only on the cost to acquire trial signups. Your full customer acquisition cost may also include sales, onboarding, and overhead expenses.
