Compound Interest Formula P = principal amount (the initial amount you borrow or deposit) r = annual rate of interest (as a decimal) Compound interest formulas to find principal, interest rates or final investment value including continuous compounding A = Pe^rt. Calculates principal, principal plus interest, rate or time using the standard compound interest formula A = P(1 + r/n)^nt. The compound interest formula is ((P*(1+i)^n) - P), where P is the principal, i is the annual interest rate, and n is the number of periods. Using the same information above, enter "Principal To calculate continuously compounded interest use the formula below. In the formula, A represents the final amount in the account that starts with an initial P using interest rate r for t years. This formula makes use of the mathemetical constant e .
