MRR Growth Rate Calculator (MoM, QoQ & YoY)

Measure recurring revenue momentum across Month-over-Month, Quarter-over-Quarter, and Year-over-Year. Clean UX with tooltips, scenarios, and a What It Means section.

$

Ending Monthly Recurring Revenue for the most recent month. Use the same currency across all inputs.

$

Ending MRR for the prior month. Used for MoM growth and net new MRR.

$

Ending MRR at the close of the prior quarter (3 months ago). If you track quarterly averages, use the average of the prior quarter.

$

Ending MRR from the same month last year. Powers Year-over-Year growth.

What is MRR Growth Rate (MoM, QoQ, YoY)?

MRR growth rate tracks how your monthly recurring revenue changes over time, expressed as a percentage for each period (month, quarter, year).

MoM highlights short-term momentum, QoQ smooths out volatility to show medium-term execution, and YoY shows whether the business is compounding at a value-creation pace that justifies headcount, capital allocation, and valuation multiples.

Formula

MoM MRR Growth = (Net MRRcurrent month − Net MRRprevious month) / Net MRRprevious month
QoQ MRR Growth = (MRRcurrent quarter end − MRRprevious quarter end) / MRRprevious quarter end
QoQ Annualized MRR Growth = (1 + QoQ MRR Growth)4 − 1
YoY MRR Growth = MRRcurrent month / MRRsame month last year − 1

Example

Assume a SaaS company has:

  • MRR 12 months ago: $60,000
  • Previous quarter-end MRR: $78,000
  • Previous month MRR: $85,000
  • Current MRR: $90,000
MoM MRR Growth = (90,000 − 85,000) / 85,000 approx 5.9%
QoQ MRR Growth = (90,000 − 78,000) / 78,000 approx 15.4%
QoQ Annualized approx (1 + 0.154) − 1 approx 77.3%
YoY MRR Growth = 90,000 / 60,000 − 1 = 50%

In this scenario, MoM shows solid recent momentum, QoQ and its annualized rate indicate breakout execution, and YoY confirms that recurring revenue has scaled by half over the last year—strong signals for NRR, CAC payback, and Rule of 40 analysis.

How to Use the MRR Growth Rate Calculator (MoM, QoQ, YoY)

Use this calculator to quickly see how fast your subscription revenue is growing month-over-month, quarter-over-quarter, and year-over-year, based on four simple MRR inputs.

Enter current MRR (latest month end)

  • Type in your total monthly recurring revenue as of the most recent month-end, using the same MRR definition you use in your billing/BI tools (no one-offs or implementation fees).

Enter previous month and previous quarter MRR

  • Add last month’s total MRR and the MRR at the end of the last full quarter. These values let the tool compute MoM and QoQ growth and the net new MRR versus last month.

Enter MRR 12 months ago to unlock YoY

  • Fill in your MRR from the same month one year earlier so the calculator can derive YoY and top-line growth. Under the hood it uses:
    • MoM MRR Growth (%) = (Current MRR − Previous Month MRR) / Previous Month MRR × 100
    QoQ MRR Growth (%) = (Current MRR − Previous Quarter MRR) / Previous Quarter MRR × 100
    QoQ Annualized (%) = [(1 + QoQ (decimal))4 − 1] × 100
    YoY MRR Growth (%) = (Current MRR − MRR 12 Months Ago) / MRR 12 Months Ago × 100.

Review the results table

  • Check MoM, QoQ, QoQ annualized, YoY, and “Net new vs last month” to understand both the percentage growth and the absolute dollar change. The “Category” row summarizes the pattern into a plain-language growth label.

Use insights to adjust your plan

  • Compare MoM/ QoQ to YoY, watch how “net new vs last month” evolves, and use the category and narrative section (“What It Means”) to decide whether to push harder on acquisition, fix churn, or protect capacity for a breakout phase.

Frequently Asked Questions

How is MRR growth rate actually calculated in this tool?

The calculator applies the standard growth-rate formula to your monthly recurring revenue for different periods. MoM, QoQ, and YoY are all variations of

Growth Rate = (Current Period MRR − Prior Period MRR) / Prior Period MRR × 100

with “prior period” set to last month, last quarter, or the same month last year.

Why does my MoM MRR growth look strong while YoY growth is only moderate?

MoM compares just one month to the immediately previous month, so short-term campaigns or discounts can make it spike, while YoY compares against where you were 12 months ago and smooths out seasonality. Use MoM for short-term signals and YoY to judge whether the business is compounding at a healthy pace.

What is QoQ annualized growth and how should I read it?

QoQ annualized takes your latest quarter-over-quarter MRR growth and projects it over a full year using compounding:

QoQ Annualized = [(1 + QoQ (decimal))4 − 1] × 100.

Use it as a directional indicator of “run-rate” growth, not as a guaranteed forecast.

How does “net new vs last month” differ from Net New MRR that SaaS benchmarks talk about?

In this calculator, “net new vs last month” is simply

Current MRR − Previous Month MRR.

Classic Net New MRR usually decomposes that change into new, expansion, churn, and contraction MRR (New + Expansion – Churn – Contraction). This tool shows the total dollar change; your billing or BI system should give you the full Net New MRR breakdown.
