What is the MRR Calculator?

The MRR Calculator is a free SaaS MRR goal calculator that reverse-engineers your monthly recurring revenue target. Tell it where you want to land — say $10k MRR — and your average price, and it shows how many customers you need, how many churn at goal, and how many months it takes to get there. It answers the question every founder asks: how many customers for $10k MRR, and what does churn really cost me?

How to use it

  1. Enter your target MRR (e.g. $10,000) and your average price per month.
  2. Optionally add your monthly churn percentage and how many new customers you sign per month.
  3. Tap "Plan it" to see customers needed, churn drag and your months-to-goal timeline.

Frequently asked questions

How many customers do I need for $10k MRR?

Divide your MRR goal by your average price. At $29/mo you need about 345 customers for $10k MRR; at $49/mo about 205. This MRR calculator does the math instantly and factors in churn.

Is this MRR calculator free?

Yes. This SaaS MRR goal calculator is completely free with no login. Enter your target MRR and price to see customers needed, churn drag and months to goal.

How does churn affect my MRR goal?

Churn means you lose a slice of customers every month, so you need gross new signups just to stay flat. Add your monthly churn percent and the calculator shows how many customers churn at goal and whether your new-customer pace can ever reach it.

How long will it take to hit my MRR goal?

Enter your new-customers-per-month rate and the MRR calculator projects how many months it takes to reach your goal, accounting for churn drag. If churn outpaces growth, it flags that the pace tops out below your target.
