MoM MRR Growth

Your guide to calculating, tracking, and benchmarking the ultimate SaaS momentum metric.

MoM MRR Growth

23.6% vs. 18.5% three months ago

Month-over-month percentage change in recurring revenue over the last 12 months

MoM MRR Growth measures the percentage change in your Monthly Recurring Revenue from one month to the next. It tells you whether your subscription business is accelerating, stalling, or losing ground.

What is MoM MRR Growth?

MoM MRR Growth is the month-over-month percentage change in the predictable, recurring revenue your subscription business collects each month.

The number captures more than new sales. It accounts for expansion revenue from upgrades, and subtracts revenue lost to cancellations and downgrades. That makes it one of the clearest signals of business momentum available to a SaaS founder or executive.

Track MoM MRR Growth alongside Net Revenue Retention Rate (NRR), which shows how well you retain and expand revenue from existing customers. For a longer horizon, Annual Recurring Revenue (ARR) Growth Rate gives you the year-over-year view that matters to investors and boards.

How to calculate MoM MRR Growth

Start by calculating Net MRR for each month: new business plus expansion revenue, minus churned revenue.

Then apply this formula:

(Net MRR This Month - Net MRR Last Month) / Net MRR Last Month

Example:

A SaaS company ends August with Net MRR of $550,000. In September:

New MRR: $100,000 from new customers
Expansion MRR: $50,000 from upgrades
Churned MRR: $20,000 from cancellations

September Net MRR:

$550,000 + $100,000 + $50,000 - $20,000 = $680,000

MoM MRR Growth:

($680,000 - $550,000) / $550,000 = 23.6%

That 23.6% tells the leadership team something concrete: the business grew faster this month than the base alone would suggest, and the expansion revenue is doing real work.

What is a good MoM MRR growth rate?

There is no single benchmark. The right number depends on where your company sits in its growth trajectory.

Early-stage (under $2M ARR): Consistent growth of 15 to 20% per month over six or more months signals product-market fit and a repeatable sales motion. That consistency is what attracts Series A investors, not a single strong month.
Growth-stage ($2M to $20M ARR): Sustaining high percentage growth becomes harder as the revenue base grows. At this stage, many companies shift their primary reporting lens from monthly to annual. A useful target: double ARR year over year.
Established (over $20M ARR): Single-digit monthly growth can still represent strong absolute gains. The conversation shifts toward capital efficiency and sustainable margin, not raw speed.

One practical note: when MRR is low (under $20,000), percentages can be misleading. Discussing growth in absolute dollar terms often gives stakeholders a clearer picture.

Common challenges and how to address them

A few patterns trip up even well-run SaaS businesses when they try to act on MoM MRR Growth.

Misreading the source of growth. A strong month might come from a one-time promotion, a single large deal, or a seasonal spike. Before deciding you've found a repeatable engine, identify exactly what drove the number.
Over-relying on past trends. SaaS growth is rarely linear. A model built on recent momentum can mislead you if market conditions or competitive dynamics shift. Treat the trend as context, not a forecast.
Optimizing for the metric instead of the business. Aggressive discounting or one-time incentives can inflate MoM MRR Growth without building durable revenue. The number should reflect real demand, not accounting choices.

The most useful discipline: build a repeatable process first, then use MoM MRR Growth to confirm it's working.

How to monitor MoM MRR Growth without the manual work

Checking a number once a month is not the same as staying on top of it. By the time you pull last month's report, you've already lost the window to act on what it's telling you.

A real-time SaaS dashboard keeps MoM MRR Growth and the metrics around it (Expansion MRR, Churned MRR, Net Revenue Retention Rate) visible without anyone having to pull a number on request. Your team sees the same data, updated automatically, so decisions come from a shared source of truth rather than whoever assembled the last spreadsheet.
