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 [math]\text{Growth Rate} = \frac{\text{Current Period MRR} - \text{Prior Period MRR}}{\text{Prior Period MRR}} \times 100[/math] 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: [math]\text{QoQ Annualized} = \left[(1 + \text{QoQ (decimal)})^4 - 1\right] \times 100.[/math] 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 [math]\text{Current MRR} - \text{Previous Month MRR}.[/math] 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.

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

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 ≈ 5.9%

QoQ MRR Growth = (90,000 − 78,000) / 78,000 ≈ 15.4%

QoQ Annualized ≈ (1 + 0.154)⁴ − 1 ≈ 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:
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.
