Formula
How the calculation works
Keep the assumptions consistent and review the result together with the practical context below.
Formula
CAGR = (Ending value ÷ Beginning value)^(1 ÷ years) − 1
The calculator applies the standard mathematical relationship to the values entered. The result is a planning estimate and should be checked against any official terms that apply.
- Beginning value: starting amount
- Ending value: final amount
- Years: complete measurement period

Decision support
A practical four-step review
1. Start with a realistic base case
Enter values from an actual quote, statement, offer or business record rather than an ideal assumption.
2. Change one input
Create a second scenario by changing only one variable so its effect is easy to understand.
3. Review the trade-off
Look beyond the headline result and consider cost, time, risk, affordability or purchasing power.
4. Verify before committing
Confirm official rates, fees, eligibility conditions and definitions with the relevant provider or professional.
Avoid errors
Common mistakes
Treating CAGR as each year’s return
CAGR is a smoothed rate between endpoints.
Using zero or negative starting value
The standard formula requires a positive beginning value.
Counting periods incorrectly
Use the actual number of years between the two values.
Ignoring cash flows
Additional deposits or withdrawals can make CAGR misleading for investments.

Frequently asked questions
Is this cagr calculator free?
Yes. It runs in your browser and provides an immediate planning result without requiring an account.
Can I use the result for a final financial decision?
Use it as a planning estimate. Verify lender, employer, tax, investment or accounting rules that apply to your exact situation.
Are my values uploaded?
The calculation is performed in your browser for this tool.
Why should I compare more than one scenario?
A single result can hide trade-offs. Changing one input at a time helps reveal the effect of rate, cost, value or time assumptions.
Can I use decimal values?
Yes. Decimal rates and amounts can be entered where the calculator field allows them.
What should I verify before acting on the result?
Check the definition of every input, the time period used, applicable fees or deductions, and any official terms that are not represented by a general calculator.

A practical guide to using CAGR without hiding volatility or cash flows
Compound annual growth rate converts a beginning value, ending value and period into one smoothed annual rate. It is useful for comparing growth over equal or different durations, but it describes the path as if growth had occurred steadily.
CAGR does not reveal interim losses, volatility, contributions, withdrawals or the risk required to achieve the ending value. Two investments with the same CAGR can deliver very different experiences.
Use CAGR with cash-flow-aware measures when money was added or removed, and pair it with drawdown, volatility, fees and inflation for a fuller performance review.
Use this calculator when
- ✓ Annualising growth between two values
- ✓ Comparing investments over different periods
- ✓ Reviewing revenue, users or portfolio growth
- ✓ Testing the rate needed to reach a target
Before trusting the result
Use several scenarios and verify fund, tax, fee, risk and cash-flow assumptions from current product documents.
Prepare reliable inputs
Include and verify
- Correct beginning value
- Correct ending value
- Exact period length
- Dividends or distributions where relevant
- Fees and taxes for net performance
- Cash flows that may require another measure
Avoid these shortcuts
- Using CAGR when the starting value is zero or negative
- Ignoring deposits and withdrawals
- Calling CAGR an average of yearly returns
- Comparing nominal and inflation-adjusted figures
- Hiding a large drawdown behind a smooth rate
- Using different data definitions across companies
A step-by-step way to use the result
STEP 1
Verify both endpoint values
Use comparable definitions and valuation dates.
STEP 2
Measure the period accurately
Use years or fractional years consistently.
STEP 3
Adjust the data if needed
Decide whether values include dividends, fees, tax and inflation.
STEP 4
Check for external cash flows
Use XIRR or another money-weighted method when cash moved in or out.
STEP 5
Compare risk and path
Review volatility and drawdowns alongside CAGR.
STEP 6
Document assumptions
Record the dates, values and whether the result is gross, net, nominal or real.
Realistic scenarios to test
Investment comparison
- Fund A doubles in 8 years
- Fund B doubles in 5 years
CAGR makes the different holding periods comparable.
Business revenue
- Start: £2 million
- End: £3 million after four years
The result summarises annualised growth but not yearly volatility.
Interim contribution
- Portfolio receives a large deposit
- Ending value rises
Simple CAGR overstates investment performance because the cash flow is ignored.
Inflation adjustment
- Nominal CAGR
- Consumer inflation over the same period
Real growth can be materially lower than nominal growth.
CAGR and simple average answer different questions
| Comparison | CAGR | Arithmetic average |
|---|---|---|
| What it measures | Compounded endpoint growth | Average of listed period returns |
| Uses beginning and ending value | Yes | Not necessarily |
| Reflects volatility drag | Through endpoints | No |
| Handles cash flows | No | No |
| Best use | Long-term annualised comparison | Average observation or expected value |
Common mistakes
- Using the wrong number of years
- Ignoring distributions
- Applying CAGR to zero or negative starting values
- Comparing gross with net results
- Assuming smooth yearly performance
- Using it for portfolios with material cash flows
Improve the decision
- Use exact dates
- State whether returns are nominal or real
- Include reinvested distributions where appropriate
- Pair CAGR with drawdown and volatility
- Use XIRR for irregular cash flows
- Compare like-for-like periods and definitions
Country and product context
India
For investment comparison, check whether NAV values include distributions and whether tax or exit loads are excluded.
United Kingdom
Distinguish fund performance from personal return after platform fees and tax wrappers.
United States
Use total-return data where appropriate and distinguish pre-tax from after-tax performance.
European Union
Use consistent currency and fund share class; cross-border comparisons may be affected by exchange rates and costs.
Frequently asked questions (20)
What is CAGR? +
It is the annual compounded rate linking a beginning value and ending value over a period.
Is CAGR the same as average return? +
No. It is a geometric annualised rate, not the arithmetic average of yearly returns.
Does CAGR show volatility? +
No. It smooths the path between endpoints.
Can CAGR be negative? +
Yes, when the ending value is below the beginning value and inputs are valid.
Can the starting value be zero? +
No. CAGR is undefined when the beginning value is zero.
Does CAGR include deposits? +
No. Material cash flows require a money-weighted measure such as XIRR.
Should dividends be included? +
Include reinvested distributions when measuring total return.
Does it include fees and tax? +
Only if the values entered are already net of them.
Can I use months instead of years? +
Convert the period accurately into years or use a calculator that accepts exact dates.
Why can CAGR differ from yearly returns? +
It reflects the compounded endpoint result rather than each yearly observation.
Can two investments have the same CAGR? +
Yes, even with very different volatility and drawdowns.
What is real CAGR? +
It is growth after adjusting for inflation.
Can I use CAGR for business revenue? +
Yes, if start and end values use consistent definitions.
Can I use it for profit? +
Yes, when profit remains positive and consistently measured.
What is XIRR? +
It is an annualised return measure for irregular dated cash flows.
Is a higher CAGR always better? +
Not without considering risk, cost, liquidity and reliability.
Are values stored? +
Only enter non-confidential performance values.
Is CAGR a forecast? +
No. Historical CAGR describes the past; required CAGR is only a scenario.
How many decimal places are useful? +
Usually one or two are enough for planning; excess precision can mislead.
What is the main limitation? +
CAGR hides the path, volatility and intermediate cash flows.

Important limitation
CAGR is a smoothed endpoint measure. It does not show volatility, risk or the effect of intermediate cash flows and should not be used alone to evaluate performance.
