CAGR Calculator
Calculate compounded annual growth rate and implied annual value progression with the WealthCalcLab CAGR calculator.
Updated April 10, 2026
What this calculator does
This CAGR calculator measures the constant annual growth rate that would turn a starting value into an ending value over a given period.
CAGR is useful because it turns irregular real-world performance into a standardized annual rate that is easier to compare across funds, businesses, portfolios, or revenue series.
It does not describe the path actually taken year to year. It describes the equivalent smooth annual rate.
This page is built for users who need a defensible planning answer, not just quick arithmetic. It translates "Start value", "End value", and "Years" into "CAGR", "Absolute growth", and "Ending value" so the trade-off is visible in one place instead of being hidden behind a single number.
How to use it
Enter the starting value, ending value, and number of years between them.
Use the result to compare performance across investments or business metrics with different time spans.
Check the implied growth path if you want to visualize what a constant annual growth rate would look like.
Start with "Start value", "End value", and "Years". Once the base case makes sense, compare one assumption at a time so you can see exactly what changes the outcome.
Formula
CAGR = (Ending value ÷ Starting value)^(1 ÷ years) - 1The formula returns the constant annual rate that links the start and end value over the chosen time horizon.
Methodology
The calculator divides the ending value by the starting value, raises the result to the inverse of the holding period, and subtracts one.
The table and chart then rebuild a smooth annual path using the calculated CAGR.
This makes the output easier to interpret without pretending that actual year-to-year performance was smooth.
The model maps "Start value", "End value", and "Years" into "CAGR", "Absolute growth", and "Ending value" using the formulas shown on the page. Keeping those relationships visible makes it easier to separate the core economics from the optional adjustments and to understand which assumption is actually moving the answer.
Worked example
If an investment grows from 10,000 to 18,000 over five years, CAGR tells you the single annualized growth rate that would produce the same result.
That makes it easier to compare with another investment that may have run for seven years rather than five.
How to interpret the results
Use CAGR for normalized comparison, not for forecasting certainty. Actual returns will almost never arrive in a perfectly smooth sequence.
A higher CAGR is generally better, but only when the risk profile and cash-flow pattern are also comparable.
Read "CAGR" first, then use the other summary cards, the chart, and the detailed table to judge contributions, growth, and future purchasing power. In most finance decisions, the best option is the one that stays strong across the full picture, not just the one with the most attractive first number.
Common mistakes
- Confusing CAGR with average arithmetic return.
- Using CAGR when there are major interim cash flows that should be handled with IRR or XIRR instead.
- Treating CAGR as a guarantee of future growth.
Key terms
Quick definitions for the finance terms that matter on this page.
CAGR
The constant annual growth rate that would produce the same start and end value over time.
Annualized growth
A standardized yearly rate used to compare performance across different time spans.
Frequently asked questions
Clear answers on assumptions, interpretation, and the limits of each estimate.
Is CAGR the same as average yearly return?
No. CAGR is a compounded rate, while a simple average does not capture compounding properly.
Can CAGR handle deposits and withdrawals?
Not well. If there are significant cash flows in between, IRR or XIRR is usually more appropriate.
Why does the chart look smooth?
Because CAGR represents a hypothetical smooth annual path, not the exact path the asset actually took.
Can CAGR be negative?
Yes. If the ending value is below the starting value, CAGR will show an annualized loss.
Which inputs change "CAGR" the most?
Start with "Start value", "End value", and "Years". Those assumptions usually drive "CAGR" far more than any optional adjustment. Once the base case is right, use advanced inputs only to reflect real fees, taxes, or timing differences.
What does "CAGR" tell me in practical terms?
"CAGR" is the fastest read on the outcome, but it should not be treated as the whole decision by itself. Use it as the headline number, then read the chart, table, and other summary cards to understand what is happening underneath.
Why should I look at "Absolute growth" as well as "CAGR"?
Because "CAGR", "Absolute growth", and "Ending value" answer different parts of the same decision. A scenario can look good on the first number and still be weak once timing, total cost, or long-run value is included.
Is the calculator still useful if I only have the main inputs?
Yes. This page is designed to produce a practical first estimate from the core inputs alone. You can refine the result later if you get better information about fees, taxes, or timing.
Does the chart add anything beyond the summary cards?
Yes. The chart shows how the result develops over time, which is often the real decision point. It is especially useful when two scenarios have a similar headline result but very different timing or cost patterns.
What is the detailed table useful for?
Use the table when you need the period-by-period breakdown behind the summary. That is usually where users spot front-loaded interest, a slow payoff path, a contribution gap, or the exact point where one scenario becomes better than another.
Should I compare more than one cagr scenario?
Yes. A base case and one stressed case usually give a much better planning view than a single run. Change one major assumption at a time so you can see what is actually responsible for the difference.
How should Turkey users validate this result before acting?
Use the calculator as a planning tool, then confirm product fees, tax treatment, contribution timing, and inflation assumptions. Final product disclosures, local tax rules, and official documentation can move the real outcome away from the estimate.
