CAGR and Annualized Return Calculator
Calculate compound annual growth rate, ending value, or required years, then compare total return, real return, linear average, and a benchmark.
CAGR and Annualized Return Calculator inputs
Choose the unknown, then enter beginning value, ending value, years, annual rate, inflation, and benchmark assumptions.
CAGR assumes no external deposits or withdrawals between the beginning and ending values. Use a cash-flow return method when timing of contributions matters.

How the annual return calculator works
This page answers the exact search intent represented by annual return calculator. The calculator keeps definitions, assumptions, intermediate values, and warnings visible so the result can be checked rather than accepted as an unexplained number.
CAGR versus total return
Total return measures the entire percentage change from beginning to ending value. CAGR converts that change into the constant compounded annual rate that would connect the two values over the entered period. It is geometric, not a simple division of total return by years.
When annualized return is valid
CAGR is appropriate for one beginning value and one ending value when no external deposits or withdrawals occur between them. If cash moves in or out, money-weighted return such as IRR or a properly timed performance method is needed because contribution timing affects the result.
Real return and benchmark comparison
The inflation-adjusted result removes the entered inflation rate through a compound ratio rather than simple subtraction. The benchmark comparison shows annualized excess return. Neither measure includes taxes, fees, risk, volatility, or sequence of returns unless those effects are already reflected in the values entered.
Reliable-use checklist
Confirm that every endpoint, unit, date, rate, period, inclusion rule, and sign matches the original problem. Save the detailed output with the input values so the calculation can be reproduced. Compare a known example before using a custom case, and consult current professional guidance when the output affects taxes, contracts, regulated benefits, or investment decisions.
The annual return calculator runs locally in the browser. It does not transmit entered values, create an account, or retain a calculation history. Full internal precision is used for the calculation, while display rounding is applied only to readable result cards and graphics.
CAGR and Annualized Return Calculator questions
Is CAGR the same as average annual return?
No. CAGR is a geometric annual rate; a simple arithmetic average can differ materially.
Can I use CAGR with monthly contributions?
Not reliably. Use a cash-flow method because the timing of contributions changes the return.
Why is real CAGR not exactly nominal minus inflation?
Compound rates combine multiplicatively, so the exact real rate uses (1+nominal)/(1+inflation)-1.
