How revenue growth is measured
Revenue growth measures how revenue changes over time. Most teams track growth by month (MRR), quarter, or year, depending on business model and reporting cadence. The simplest measure is period-over-period growth: how much did revenue change compared to the previous period?
Growth is usually expressed as a percentage so you can compare across periods even when the absolute revenue numbers are very different. For example, going from $50k to $60k in a month is 20% growth, while going from $500k to $600k is also 20% growth — but the operational meaning and constraints can be different.
This tool shows multiple growth summaries: average period growth (arithmetic), median period growth (robust to outliers), and CAGR (geometric). That matters because revenue data can be volatile and a single spike can distort averages.
Average growth vs CAGR
Average growth is the arithmetic mean of period-over-period growth rates. It answers: “If we average the changes each period, what is the typical rate?” This can be useful for short-term monitoring.
CAGR is a smoothed rate that connects the start and end values. It answers: “What constant growth rate would produce the same start and end?” CAGR is helpful for comparing growth across different time windows or across companies, because it reduces volatility into a single number.
In volatile data, average growth can be biased upward or downward depending on the order and size of swings. CAGR avoids some of that by using a geometric approach.
Annualizing growth rates (monthly and quarterly)
Annualizing a growth rate means expressing a per-period rate as an equivalent yearly rate. The key is compounding. If you grow 5% every month, the annualized growth is not 60% — it is (1.05^12 − 1) ≈ 79.6%.
This calculator annualizes both the average per-period rate and the per-period CAGR using the cadence you select. That helps you compare monthly performance to yearly targets or to benchmarks.
Using projections responsibly
Projections are scenario tools. They assume the same growth rate continues. Reality is messier: capacity, sales cycles, pricing changes, churn, competition, and macro conditions all affect outcomes.
The best way to use projections is to run multiple scenarios: a conservative rate (median or lower quartile), a base case (CAGR), and an aggressive rate (recent average). Then compare those trajectories to hiring plans, burn rate, and pipeline.
Frequently Asked Questions
What is revenue growth?
Revenue growth measures how much your revenue increases (or decreases) over time. It is usually expressed as a percentage relative to the previous period. Tracking revenue growth helps you understand whether sales momentum is improving, whether pricing changes are working, and how seasonal cycles affect performance.
How do you calculate period-over-period revenue growth?
A common formula is: (current period revenue − previous period revenue) ÷ previous period revenue. The result is a rate; multiply by 100 to get a percentage. This calculator computes period growth across a series and also summarizes the average and median growth rates.
What is CAGR and when should I use it?
CAGR (compound annual growth rate) is the constant growth rate that would take you from the starting revenue to the ending revenue over the number of periods. It smooths out volatility and is useful for comparing growth across companies or across different time windows.
What is the difference between average growth and CAGR?
Average growth is the arithmetic mean of period-over-period growth rates. CAGR is a geometric rate based on start and end values. When growth is volatile, the average can be misleading, while CAGR provides a smoother “equivalent” growth rate.
How do you annualize monthly or quarterly growth?
To annualize a per-period growth rate, you compound it across the number of periods in a year: (1 + rate)^(periods per year) − 1. This calculator does that for both the average per-period rate and the per-period CAGR, so you can view annualized growth consistently.
Are projections guaranteed?
No. Projections are a planning tool. They assume a constant growth rate going forward and do not account for capacity limits, market changes, churn, pricing shifts, or macro conditions. Use projections to sanity-check targets and to explore scenarios, not as a promise of future results.
