Assumptions used

What this answer assumes

Best for investment statements, revenue growth, website traffic, business metrics, classroom finance examples and board-pack notes where the period and endpoints need to stay visible.

  • Starting value must be greater than zero because CAGR divides by the starting value.
  • The calculator treats the start and end values as positive nominal values before taxes, fees, cash flows or inflation adjustments unless the user has already included them.
  • CAGR is a smoothed annual rate; it does not show volatility, drawdowns, sequence of returns or cash-flow timing inside the period.
  • The comparison annual rate compounds once per year for a simple benchmark scenario.
  • For investment, tax, accounting or legal decisions, confirm figures with the original statements and a qualified professional where needed.

Master’s Tip

How to use the result well

Master’s Tip: use CAGR to compare long-period growth rates, but do not mistake it for a year-by-year history. Print the start value, end value and years beside the CAGR so the smooth rate does not hide a bumpy path.

Direct answer

CAGR Calculator in one sentence

A CAGR calculator turns total growth over several years into one smoothed annual rate. This page keeps the starting value, ending value, years, growth multiple, annualised percentage and comparison-rate scenario visible so an investment, revenue or classroom growth record can be printed and checked later.

How to use this calculator

  1. Enter starting value, ending value, time period, comparison annual rate.
  2. Check the formula, assumptions and worked example before reusing the number.
  3. Use the result, related calculators and printable record as the next practical step.

Use this CalculationTime result as the source: CAGR Calculator. Default output: Compound annual growth rate = 12.47%. Formula/method: CAGR = (ending value ÷ starting value)^(1 ÷ years) − 1. Growth multiple = ending value ÷ starting value. Comparison ending value = starting value × (1 + comparison rate ÷ 100)^years.. Explain the result, state the assumptions, and suggest the next calculation to check.
Formula

CAGR = (ending value ÷ starting value)^(1 ÷ years) − 1. Growth multiple = ending value ÷ starting value. Comparison ending value = starting value × (1 + comparison rate ÷ 100)^years.

Worked example

If a value grows from 10,000 to 18,000 over 5 years, the growth multiple is 18,000 ÷ 10,000 = 1.8. CAGR = 1.8^(1 ÷ 5) − 1 = 12.47% per year, before any taxes, fees, inflation or cash-flow timing adjustments.

Professional note

Assumptions and limitations

Methodology & Accuracy

How this calculator is checked

CalculationTime pages are built around visible arithmetic: the formula, assumptions, worked example and practical limitations are shown so the result can be checked rather than simply trusted.

Formula used

CAGR = (ending value ÷ starting value)^(1 ÷ years) − 1. Growth multiple = ending value ÷ starting value. Comparison ending value = starting value × (1 + comparison rate ÷ 100)^years.

Standard or basis: compound annual growth rate using ordinary annual compounding arithmetic. This is a comparison and worksheet calculator, not financial advice, accounting treatment, tax guidance or a performance guarantee.

Where a calculator follows a named legal, trade or industry standard, that standard is cited visibly. Otherwise the page uses transparent general arithmetic and states its limits.

Knowledge check

Test your understanding

Use these quick checks to confirm that the result, formula and assumptions make sense before you reuse the number.

Which inputs drive the default result?

The default result starts with Starting value, Ending value, Time period. The current pre-solved output is compound annual growth rate = 12.47%.

Where is the calculation proof?

The proof is in the formula, worked example and assumptions sections. Together they show the arithmetic, the default state and the limits of the result.

What should you do after reading the answer?

Use the related calculators, printable record or source notes to check the next practical step instead of treating one output as the end of the workflow.

Questions

How do I calculate CAGR?

Divide the ending value by the starting value, raise that ratio to 1 divided by the number of years, then subtract 1. Multiply by 100 to read it as a percentage.

What does CAGR mean?

CAGR means compound annual growth rate. It is the constant annual rate that would take the starting value to the ending value over the selected period.

Is CAGR the same as average annual return?

No. CAGR is a compounded annualised rate. A simple average of yearly returns can give a different answer when returns vary from year to year.

Can CAGR be negative?

Yes. If the ending value is lower than the starting value, CAGR is negative because the value shrank over the period.

What should I print for a CAGR comparison?

Print the starting value, ending value, years, CAGR, growth multiple, comparison annual rate, benchmark ending value, formula, assumptions, date, page URL and notes about the data source.

Calculation note

CAGR is popular because it compresses multi-year growth into one comparable annual rate. That simplicity is useful, but the printed record should keep the endpoints and time period visible so the rate is not read as a promise about each individual year.

CAGR is a smoothing tool

Real growth rarely happens in identical yearly steps. CAGR answers a controlled question: what steady annual rate would connect the starting value to the ending value over the selected time?

The starting value is the denominator

Because the formula divides by the starting value, the starting figure must be positive and meaningful. Mixing net and gross figures, or adding cash flows without adjustment, can make the CAGR misleading.

Printable comparisons prevent overclaiming

A useful CAGR record keeps the formula, endpoints, years, benchmark scenario and limitations together. That makes it suitable for classroom examples, board notes or preliminary investment comparisons without implying advice.
