Sales Funnel Subscription Revenue Calculator
Estimate subscription revenue from your sales funnel using traffic, conversion rates, pricing and churn assumptions.
Overview
The Sales Funnel Subscription Revenue Calculator helps you estimate how many paying subscribers your funnel could produce and how much recurring revenue that could add each month. Enter your monthly visitors, conversion rates, subscription price, churn rate and ad spend to model subscriber growth and recurring revenue potential.
How it works
The calculator estimates leads from your monthly visitors, then applies your lead-to-paid conversion rate to estimate new subscribers. It multiplies those new subscribers by your monthly subscription price to estimate the recurring revenue added in a month. To estimate longer-term performance, it uses churn to approximate average customer lifetime and then estimates steady-state subscribers and MRR when new signups and cancellations balance out.

With 10000 visitors, a 20% visitor-to-lead rate and a 15% lead-to-paid rate, the funnel produces about 300 new subscribers. At $49 per month, that adds roughly $14700 in new monthly recurring revenue. With 5% monthly churn, estimated steady-state MRR is about $294000, and acquisition cost is about $16.67 per subscriber.
Frequently asked questions
What does this calculator estimate?
It estimates how many new paying subscribers your funnel may generate, the recurring revenue added each month, customer lifetime value, acquisition cost and an approximate steady-state MRR.
What is steady-state MRR?
Steady-state MRR is an estimate of recurring revenue once new subscriber growth and subscriber churn balance out under the same ongoing assumptions.
How is customer lifetime value calculated here?
This version uses a simple revenue-based estimate: monthly subscription price multiplied by estimated customer lifetime in months based on churn.
Does this include upgrades, downgrades or annual plans?
No. This calculator assumes a single average monthly subscription price and does not separately model pricing tiers, expansion revenue or annual billing.
Why does churn matter so much?
Churn strongly affects how long customers stay subscribed. Lower churn usually increases both lifetime value and steady-state recurring revenue.
Is ad spend required?
Ad spend is used to estimate customer acquisition cost and first-month ROI. If you have no paid acquisition spend, you can enter 0, but cost-based outputs will be less meaningful.
