wzlxp.top builder tools MRR calculator
Estimate monthly recurring revenue from plan counts, subscription prices, churn, expansion, downgrades, and discounts. Use it with the runway calculator to connect revenue progress with operating decisions.
Keep inputs aggregate. This page is for planning MRR from segments, not storing customer-level revenue data.
Estimated planning result only. This simple MRR model uses plan counts, prices, churn, expansion, contraction, and discounts.
It does not replace billing analytics, revenue recognition, accounting reports, or investor-ready SaaS metrics.
How to use
Add customer counts and monthly prices for each subscription segment you want to model.
Estimate monthly logo churn, expansion MRR, downgrades, and discounts so net MRR is not overly optimistic.
Set a target MRR to see the remaining revenue gap and the number of customers needed at current ARPA.
MRR planning guide
A SaaS MRR calculator should help a founder understand what revenue is recurring, what is leaking through churn or discounts, and what gap remains before the next milestone.
Plan customers are multiplied by monthly plan prices to estimate gross monthly recurring revenue before discounts or churn.
Discounts, churned MRR, downgrades, and contraction are subtracted, while expansion MRR is added back to show a more realistic monthly run rate.
ARR is net MRR multiplied by 12. The target gap shows how much additional MRR is needed to reach a milestone.
A small subscription product with a mix of starter, growth, pro, and one enterprise customer.
A high-volume self-serve SaaS business where churn, discounts, and ARPA matter more than enterprise deal size.
A lower-volume business where expansion and enterprise contracts can move MRR faster than new logos.
References and assumptions
This calculator treats plan prices as monthly subscription prices. If customers pay annually, convert the contract into a monthly equivalent before entering it.
Expansion MRR should represent recurring upgrades or seat expansion. One-time services, setup fees, refunds, taxes, and payment processor fees should be modeled outside MRR.
The output is intended for founder planning. Use your billing system, accounting system, and finance process for official revenue reporting.
