Compound Interest Meaning
Compound interest means that the interest you earn in each compounding period is added to your principal, so that the balance doesn't merely grow, it grows at an increasing rate.
Compound Interest Formula
- A = the future value (or FV) of the investment/loan, including interest
- P = the principal investment amount (the initial deposit or loan amount also known as present value or PV)
- r = the annual interest rate expressed in decimal form (decimal = %/100). r is also known as rate of return.
- n = the number compounding periods per year (n = 1 for annually, n = 12 for monthly, etc.)
- t = the time in years or fraction of years (multiples of 1/n. Ex.: 2/n, 3/n, etc.)
