Sales Funnel Free Trial Conversion Calculator
Estimate how many paid customers, how much revenue, and what customer acquisition economics you can expect from your free trial funnel.
Overview
The Sales Funnel Free Trial Conversion Calculator helps you estimate how your traffic, free trial signup rate, trial-to-paid conversion rate, pricing, and marketing spend translate into new customers and revenue. It is useful for planning growth targets, testing conversion assumptions, and checking whether your funnel economics look sustainable.
How it works
The calculator starts with your monthly visitors and applies your free trial signup rate to estimate trial signups. It then applies your trial-to-paid conversion rate to estimate new paying customers. Revenue is estimated by multiplying paying customers by your average monthly price. Customer lifetime value is estimated from average monthly price multiplied by average customer lifetime in months. Acquisition efficiency is shown using customer acquisition cost and the LTV to CAC ratio.

With 10000 monthly visitors, an 8% free trial signup rate, and a 20% trial-to-paid conversion rate, the funnel would generate about 160 paid customers per month and roughly $7840 in new monthly recurring revenue. With a $49 average monthly price and a 12-month lifetime, estimated lifetime value would be about $588 per customer.
Frequently asked questions
What does this calculator estimate?
It estimates trial signups, paid customer conversions, new monthly recurring revenue, customer acquisition cost, lifetime value, and an LTV to CAC ratio based on your funnel inputs.
What is a good free trial conversion rate?
That varies by product, market, pricing, onboarding, and traffic quality. This calculator is best used to compare scenarios and test how changes in conversion affect results.
Does this calculate total company MRR?
No. It estimates the new recurring revenue added by the customers converted from one month of funnel activity, not your full existing subscription base.
How is customer lifetime value calculated here?
This version uses a simple estimate: average monthly price multiplied by average customer lifetime in months. It does not include gross margin, upsells, refunds, or discounting.
What costs are included in CAC?
CAC here is calculated using the monthly traffic acquisition cost you enter divided by estimated new paying customers. It does not automatically include salaries, software, or sales overhead.
Can I use this for annual plans or mixed pricing?
Yes, but it works best when you enter a realistic average monthly price per converted customer. If you have mixed plans, use a blended average.
