How to Calculate MRR for Your Small Business: A Practical Guide

What Is MRR and Why Should You Track It?

Monthly Recurring Revenue (MRR) is the predictable revenue your business earns every month from subscriptions, retainers, or recurring contracts. Unlike one-time sales, MRR gives you a baseline you can count on — and it's the metric investors, lenders, and acquirers look at first.

Even if you're not seeking funding, MRR tells you whether your business is growing, stagnating, or shrinking. It's the single best indicator of business health for any company with recurring revenue.

How to Calculate MRR

The basic formula is straightforward:

MRR = Number of Customers × Average Revenue Per Customer Per Month

But real businesses have complexity. Here's how to handle common scenarios:

New MRR

Revenue from customers who subscribed this month. If you gained 10 new customers at $50/month, your New MRR is $500.

Expansion MRR

Additional revenue from existing customers who upgraded. If 5 customers moved from your $50 plan to your $100 plan, Expansion MRR is $250.

Churned MRR

Revenue lost from customers who cancelled. If 3 customers at $50/month left, Churned MRR is $150.

Net New MRR

Net New MRR = New MRR + Expansion MRR − Churned MRR

Using our example: $500 + $250 − $150 = $600 Net New MRR. A positive number means you're growing.

Handling Annual Subscriptions in MRR

If a customer pays $1,200 annually, their MRR contribution is $100/month ($1,200 ÷ 12). Always normalize annual contracts to monthly equivalents for accurate MRR calculations.

AESTIMO handles this automatically. When you log recurring revenue with annual billing, the system normalizes it to monthly figures in your P&L dashboard.

MRR Benchmarks for Small Businesses

Healthy MRR growth rates vary by stage:

• Early stage (under $10K MRR): 15-20% month-over-month growth is strong
• Growth stage ($10K-$100K MRR): 10-15% monthly growth is solid
• Scale stage ($100K+ MRR): 5-10% monthly growth is healthy

The key metric to watch is your ratio of New + Expansion MRR to Churned MRR. If that ratio is above 1, you're growing. Below 1, you're shrinking regardless of how many new customers you add.
