What is MRR (Monthly Recurring Revenue)?

Also known as: Monthly Recurring Revenue, Recurring monthly revenue

Definition

The predictable monthly revenue an agency (or SaaS company) generates from subscriptions — a key KPI because it measures stable income, unlike one-off projects.

In-depth explanation

For agencies working with retainer models (a fixed monthly fee per client), MRR is the cornerstone of financial planning. An agency with 15 clients at an average of €1,200/month has an MRR of €18,000 — predictable and stable. One-off projects (logo design, a one-time consult) don't count toward MRR.

What grows MRR: new clients (new MRR), price increases or upsells with existing clients (expansion MRR). MRR drops through churn (a client leaves) or contraction (a client moves to a lower plan).

Example from agency practice

An agency started January with 10 clients × €1,000 = €10,000 MRR. By May: 14 clients × an average of €1,150 = €16,100 MRR. Growth of €6,100 MRR in four months = a strong trend. On the basis of MRR the CFO can forecast whether there's room for extra staff.
