Compound annual growth rate (CAGR) is a business, economics and investing term representing the mean annualized growth rate for compounding values over a given time period. CAGR smoothes the effect of volatility of periodic values that can render arithmetic means less meaningful. It is particularly useful to compare growth rates of various data ...
Compound interest. Compound interest is interest accumulated from a principal sum and previously accumulated interest. It is the result of reinvesting or retaining interest that would otherwise be paid out, or of the accumulation of debts from a borrower.
The effective interest rate ( EIR ), effective annual interest rate, annual equivalent rate ( AER) or simply effective rate is the percentage of interest on a loan or financial product if compound interest accumulates in periods different than a year. [1] It is the compound interest payable annually in arrears, based on the nominal interest rate.

If you put $1,000 into a compound interest savings account offering 6% interest compounded daily, after two years you would have earned $127.49. This would bring your account total to $1,127.49.
The formula for the annual equivalent compound interest rate is: (+) where r is the simple annual rate of interest n is the frequency of applying interest. For example, in the case of a 6% simple annual rate, the annual equivalent compound rate is:
Exponential growth is a process that increases quantity over time at an ever-increasing rate. It occurs when the instantaneous rate of change (that is, the derivative) of a quantity with respect to time is proportional to the quantity itself.
