What is a good CAGR for a business?

It depends heavily on industry and stage. Early-stage startups often target 100%+ annual revenue CAGR, while mature public companies in stable industries might see 3–10% CAGR as healthy. For public equities broadly, the S&P 500 has historically delivered roughly 10% nominal CAGR over long periods, which is a common benchmark.

How is CAGR different from average annual growth rate?

Average annual growth rate is a simple arithmetic mean of each year's percentage change, which can overstate true growth when returns are volatile. CAGR accounts for compounding and reflects the actual path from the beginning value to the ending value, making it the more accurate measure for multi-year comparisons.

Can CAGR be negative?

Yes. A negative CAGR means the ending value is lower than the beginning value — the metric shrank over the period. The formula works the same way; the result is simply a negative percentage, indicating compound annual decline rather than growth.

Can I calculate CAGR with fractional years?

Yes. If your period is 2.5 years or 18 months (1.5 years), enter that decimal value for n. The formula works identically with non-integer time periods, which is useful when comparing values measured at irregular intervals.

Does CAGR account for volatility or risk?

No. CAGR only uses the beginning and ending values — it ignores everything that happened in between, including large drawdowns, volatility, or temporary reversals. Two investments can have identical CAGR but very different risk profiles; always review the full performance history alongside CAGR.

How do I use CAGR to project future values?

Multiply your current value by (1 + CAGR)^n, where n is the number of future years you're projecting. For example, at a 13% CAGR, $92,000 projected forward 5 years would become $92,000 × (1.13)^5 ≈ $169,500 — though this assumes growth continues at the same historical rate, which is not guaranteed.

What's the difference between CAGR and IRR?

CAGR assumes a single beginning value and a single ending value with no cash flows in between. IRR (Internal Rate of Return) accounts for multiple cash flows occurring at different times, such as periodic investments or withdrawals, making it more appropriate for scenarios with ongoing contributions or distributions.

CAGR — Compound Annual Growth Rate — is the single number analysts, investors, and business owners use to describe how fast something grew over multiple years, smoothed into one steady annual rate. It answers a simple but easily-botched question: "If this grew at the same percentage every single year, what would that percentage be?" Unlike a simple average of yearly returns, CAGR accounts for compounding, so it accurately reflects the real path from a starting value to an ending value.

CAGR shows up everywhere: comparing mutual fund performance, evaluating a startup's revenue trajectory, benchmarking a company's stock price growth against competitors, or projecting how a business metric might continue to trend. Because it collapses multi-year, often volatile, year-to-year swings into one clean figure, it is the standard for comparing growth across different investments, time periods, and companies.

Our CAGR calculator takes your beginning value, ending value, and the number of years between them, then instantly returns the compound annual growth rate. Enter a startup's revenue at year one and year four, or a stock's price five years ago and today, and get an apples-to-apples growth rate you can use for comparison, forecasting, or reporting.

Why CAGR Calculator Matters

CAGR matters because raw growth numbers and simple averages routinely mislead. A stock that gains 100% one year and loses 50% the next has an average annual return of 25% — but the actual value is unchanged (a $100 investment becomes $200, then back to $100). CAGR correctly reports this as 0%, because it measures the true compounded path rather than an arithmetic average of percentage changes.

Investors use CAGR to compare returns across funds, stocks, or asset classes over different holding periods on equal footing. Business owners and analysts use it to describe revenue growth, user growth, or profit growth in a way that is comparable across companies of different sizes and ages — a common metric in pitch decks, board reports, and equity research. Because CAGR assumes smooth, steady growth, it also serves as a simple forecasting tool: once you know a business's historical CAGR, you can project future values under a "steady growth" assumption, though real growth is rarely perfectly linear.

CAGR is also central to due diligence. When comparing two competing investments or acquisition targets, the one with the higher CAGR delivered more value per year of compounding — even if their total dollar gains look similar on the surface.

The CAGR Calculator Formula, Explained

CAGR = (Ending Value / Beginning Value)^(1/n) − 1

Where: Ending Value = the value at the end of the period, Beginning Value = the value at the start of the period, n = number of years between the two values.

The formula works by finding the constant annual growth factor that, when compounded n times, turns the beginning value into the ending value. Raising the ratio to the power of (1/n) is the mathematical inverse of compounding — it "undoes" n years of growth to isolate the single-year rate. Subtracting 1 converts the growth factor (e.g., 1.13) into a percentage growth rate (13%).

CAGR requires only two data points — the start and end values — and completely ignores the path taken between them. This is both its strength (simplicity, comparability) and its limitation (it hides volatility along the way).

How to Use the CAGR Calculator: Step by Step

Enter the beginning value
Input the starting figure — an investment's initial value, a company's revenue in year one, or any metric at the start of your measurement period.
Enter the ending value
Input the value at the end of the period you're measuring, using the same units and currency as the beginning value.
Enter the number of years
Specify how many years separate the beginning and ending values. Use fractional years (e.g., 2.5) if the period isn't a whole number of years.
Calculate CAGR
The calculator applies the formula and returns your compound annual growth rate as a percentage, representing the steady yearly growth rate that connects your two values.
Compare and forecast
Use the resulting CAGR to compare against benchmarks, competitors, or alternative investments, or to project future values assuming the same growth rate continues.

CAGR Calculator Examples: Real-World Scenarios

Evaluating a Stock Investment

Priya bought shares worth $50,000 five years ago. Today the position is worth $92,000. She wants to know her annualized return to compare it against her other investments.

Beginning value:$50,000

Ending value:$92,000

Years (n):5

Calculation

CAGR = (92,000 / 50,000)^(1/5) − 1 = (1.84)^0.2 − 1 = 1.12970 − 1

Result

CAGR = 12.97%. Priya's investment grew at a steady equivalent rate of about 13% per year — a figure she can now directly compare to index fund returns or other holdings.

Startup Revenue Growth for a Pitch Deck

A SaaS startup had $2,000,000 in annual revenue four years ago and now generates $5,000,000 per year. The founders want to state their revenue CAGR in an investor pitch.

Beginning value:$2,000,000

Ending value:$5,000,000

Years (n):4

Calculation

CAGR = (5,000,000 / 2,000,000)^(1/4) − 1 = (2.5)^0.25 − 1 = 1.25743 − 1

Result

CAGR = 25.74%. The company can accurately state it has grown revenue at a 25.7% compound annual rate — a strong, comparable growth figure for investors evaluating multiple deals.

Spotting a Declining Business Line

A retailer's brick-and-mortar division had $1,200,000 in sales three years ago, and sales have fallen to $800,000 today. Management wants a precise decline rate for planning.

Beginning value:$1,200,000

Ending value:$800,000

Years (n):3

Calculation

CAGR = (800,000 / 1,200,000)^(1/3) − 1 = (0.6667)^0.3333 − 1 = 0.87358 − 1

Result

CAGR = −12.64%. Sales are shrinking at a compound rate of about 12.6% per year, a clear, quantified signal that this division needs intervention.

Common Mistakes to Avoid

Treating CAGR as a real, smooth year-by-year growth path — CAGR only describes the start and end points. Actual annual results can swing wildly above and below the CAGR figure while still producing the same overall growth.
Confusing CAGR with the simple average of annual percentage returns. A sequence of +50% and −50% averages to 0%, but the actual CAGR is negative because the losses compound on a smaller base.
Using CAGR over very short periods (under 1 year) or with negative/zero beginning values, where the formula produces misleading or undefined results.
Extrapolating CAGR far into the future as a guaranteed forecast. Historical compound growth rates, especially high ones, rarely persist indefinitely — markets and businesses mature and growth typically slows.

Tips & Tricks

Use CAGR to compare investments or business metrics over the same time period — comparing a 3-year CAGR to a 10-year CAGR can be misleading since longer periods tend to smooth out short-term volatility.
When presenting CAGR to investors or stakeholders, pair it with the actual beginning and ending values so readers can judge the real dollar magnitude, not just the rate.
For volatile metrics (like a single stock), also check the standard deviation or year-by-year figures — CAGR alone can mask large swings and risk along the way.

CAGR turns a messy multi-year growth story into one clean, comparable number — essential for evaluating investments, benchmarking business performance, and building credible forecasts. Just remember it describes the destination, not the journey: two investments with identical CAGRs can have very different risk profiles along the way.
