Many finance websites, including Investopedia, CalculatorEdge and NCalculators.com, offer compounded annual growth rate calculators for their users. All of these sites require the user to input information essential for calculation of the compound annual growth rate.
On all these sites, the user has to provide the initial value of the investment, the ending value and the number of periods in years. The user then clicks a button to compute the compound annual growth rate. These sites display the result immediately.
CalculatorEdge and NCalculators.com allow the user to select the currency to use in the calculation. NCalculators.com also gives users the chance to calculate the ending amount by using the state value, compound annual growth rate and the number of years.
