# SaaS MRR Calculator and Benchmarks

With our interactive MRR calculator, discover how each component—new MRR, expansion, churn, and more—affects your bottom line. Learn why reducing churn, even by a small percentage, can create significant long-term gains, and explore how benchmarks help you set ambitious, achievable growth targets.

This guide introduces two interactive SaaS MRR calculators: one simple and one advanced. Both tools let you calculate MRR in real time, using essential inputs to analyze Net New MRR, Contraction, Churn, ARPU, and other key components that impact your bottom line.

**Simple MRR Formula: **

MRR = Total Number of Active Customers × Average Revenue per Customer

**Advanced MRR Formula:**

ARR = Gross New MRR +
Expansion MRR +
Reactivation MRR −
Contraction MRR −
Churn MRR +
Previous Month's MRR

#### Advanced MRR Calculator Formula Explanation

Suppose you have the following metrics for this month:

= $2,00,000**Gross New MRR**= $60,000**Expansion MRR**= $10,000**Contraction MRR**= $180,000**Churn MRR**= $5,000**Reactivation MRR**= $700,000**Previous MRR**

Here’s how these components contribute to your ** Total MRR** and

**:**

**Net New MRR**** Calculating Net New MRR**:

Net New MRR = Gross New MRR + Expansion ARR + Reactivation MRR − Contraction MRR − Churn MRR = 75,000

** Calculate Total MRR**:

Total MRR = Previous month's MRR + Net New MRR = 775,000
