Your real growth rate,not the lumpy one.
A business that goes 0%, then 80%, then 10% didn't grow 30% a year — that's the average, and the average lies. CAGR gives you the single smooth rate that actually got you from start to finish, so you can compare years, benchmark periods, and project forward without fooling yourself.
Your numbers
Where you started: revenue, users, AUM, anything you measure at the start of the period.
Where you ended up after the full period — the same metric, measured at the end.
The length of the period. Decimals are fine — 2.5 years works.

Where your rate lands
Rule-of-thumb bands, not a published dataset. A 15% rate is excellent for a mature business and ordinary for an early-stage one — judge it against your cost of capital.
Project forward · same rate, more years
What this CAGR buys you next
| From today | Projected value | Gain vs. now |
|---|---|---|
| +1 year | $339,302 | $89,302 |
| +3 years | $625,000 | $375,000 |
| +5 years | $1,151,260 | $901,260 |
If your 35.7% CAGR held, $250,000 becomes $1,151,260 in five years. The longer the runway, the more the compounding does the heavy lifting — but a rate off a small base rarely survives scale.
The average lie · why CAGR is the honest number
Same endpoints, two different stories
CAGR (compounding-aware)
35.7%
Average yearly growth
50.0%
Your numbers grew at a true 35.7% a year. The simple average says 50.0% — 14.3% too high, because dividing total growth by years ignores compounding. CAGR is the rate to quote, compare, and forecast from.
Your move
A clean growth rate is step one. Compounding it on purpose is the work.
CAGR 35.7% a year — $100,000 → $250,000 over 3 years (2.50×).

Plain English
CAGR is the rate that tells the truth.
Compound annual growth rate (CAGR) is the single constant rate that would have taken you from your beginning value to your ending value over the period, as if you grew by exactly that percentage every year. It's the geometric mean of your growth — the honest version, because it accounts for compounding.
Why not just average the yearly growth rates? Because the simple average overstates almost everything. Go from $100 to $200 to $100 over two years and your average annual growth is +25% — you're flat. CAGR over that same period is 0%, which is the truth. Volatility inflates the average; CAGR strips it out.
This calculator gives you the real rate from three numbers — where you started, where you ended, and how long it took — plus the total growth across the whole period, the growth multiple, and the absolute gain in dollars. Then it projects that same rate forward, so you can see what another one, three, or five years of compounding actually buys.
The formula
CAGR = (Ending ÷ Beginning) ^ (1 ÷ Years) − 1
Grow from $100,000 to $250,000 over 3 years: 250,000 ÷ 100,000 = 2.5× total. Raise 2.5 to the power of 1/3 ≈ 1.357, subtract 1 → CAGR ≈ 35.7% a year. Total growth is +150%, but you didn't grow 50% a year (150 ÷ 3) — the compounding means the true annual rate is lower.
What counts as a good CAGR
A good CAGR is the one that beats your cost of capital, clears inflation, and holds up as your base gets bigger. There's no universal number — a 15% CAGR is excellent for a mature company and unremarkable for an early-stage one. These are operator rule-of-thumb bands, not a published dataset:
| CAGR band | What it typically signals |
|---|---|
| Below 0% | Shrinking. The compounding is working against you — find the leak before you model anything forward. |
| 0–10% | Steady but slow. Fine for a mature, cash-generating business; thin for anything calling itself growth-stage. |
| 10–25% | Solid, durable growth. The zone most healthy small-and-mid businesses live in and can sustain for years. |
| 25–50% | Fast. Strong for a scaling company — the real question becomes whether it holds as the base gets bigger. |
| 50%+ | Hypergrowth. Impressive, but check the base: huge percentages off a tiny start rarely survive contact with scale. |
Rule-of-thumb operator bands — not a published dataset. Context decides everything: stage, sector, and starting size. Your real bar is beating your cost of capital and clearing inflation.
Read your CAGR
CAGR is negative.
You're compounding downward. Stop projecting forward and find the cause — pricing, churn, a one-off bad year dragging the period. A single number is hiding the story; pull the year-by-year.
High CAGR off a tiny base.
200% growth from $1k to $3k is real but fragile. The same rate is almost impossible to hold as the base scales. Judge the absolute gain and the trajectory, not just the headline percentage.
Solid CAGR but one year carried it.
CAGR smooths a lumpy reality. If one breakout year is doing all the work, the rate isn't repeatable. Look at the path, not just the endpoints, before you forecast off it.
CAGR below inflation.
In real terms you shrank. Nominal growth that trails inflation is treading water at best. Benchmark against your cost of capital, not against zero.
How to lift your CAGR
01Protect the base
Compounding only works on what you keep. Cutting churn lifts CAGR more reliably than chasing new logos, because retained growth stacks every year.
02Grow what compounds
Recurring revenue, repeat purchase, and referral loops compound; one-off spikes don't. Prioritize the lines that carry into next year's base.
03Raise prices deliberately
A small annual price increase compounds straight into CAGR with near-zero cost. Most businesses under-price and leave years of growth on the table.
04Reinvest the gain
CAGR rewards plowing returns back in rather than pulling them out. The earlier you reinvest, the more years that capital has to compound.
05Shorten the cycle
Faster sales cycles and quicker onboarding mean more compounding periods inside the same calendar. Velocity is a growth-rate lever, not just an ops one.
06Stack growth channels
One channel plateaus; a portfolio compounds. Layer a second and third acquisition source before the first one taps out.
The vocabulary
- CAGR
- Compound annual growth rate: the constant yearly rate that links your beginning and ending value over a period. The geometric, compounding-aware growth rate.
- Average annual growth
- The arithmetic mean of yearly growth rates. Almost always higher than CAGR because volatility inflates it; useful for almost nothing.
- Total growth
- The full percentage change from start to end across the whole period: (ending ÷ beginning − 1) × 100. Not annualized.
- Growth multiple
- Ending value ÷ beginning value, expressed as a multiple. 2.5× means you ended at two and a half times where you started.
- Geometric mean
- The averaging method CAGR uses. It multiplies the growth factors and takes the nth root, which correctly accounts for compounding.
CAGR questions, straight answers
CAGR is the compound annual growth rate — the single constant rate that would take you from your starting value to your ending value over the period, as if you grew by exactly that percentage every year. It's calculated as (ending ÷ beginning) ^ (1 ÷ years) − 1, and it's the honest measure of growth because it accounts for compounding.
