Compound interest is the interest calculated based on both the initial and the accumulated interest from previous periods. Visit BYJU'S to completely learn about compound interest formulas and computations.
The basic formula for Compound Interest is: FV = PV (1+r) n. Finds the Future Value, where: FV = Future Value, PV = Present Value, r = Interest Rate (as a decimal value), and; n = Number of Periods; And by rearranging that formula (see Compound Interest Formula Derivation) we can find any value when we know the other three:
Compound Interest Formula. What is Compound Interest? Let us first understand the meaning and concept of compound interest and then move onto the compound interest formula. Now interest is the amount we calculate on the principal amount.
Compound Interest Formula. The formula for the Compound Interest is, \ (\begin {array} {l}Compound\;Interest\,=\,P (1+\frac {r} {n})^ {nt}\,-\,P\end {array} \) This is the total compound interest which is just the interest generated minus the principal amount.
The compound interest formula is: Where: A represents the final amount. P represents the original principal amount. r is the interest rate over a given period. n represents the number of times the interest rate is applied. E.g. Let’s calculate a 3% increase (per year) on an amount P using compound interest over 4 years.
Compound interest, or 'interest on interest', is calculated using the compound interest formula A = P*(1+r/n)^(nt), where P is the principal balance, r is the interest rate (as a decimal), n represents the number of times interest is compounded per year and t is the number of years.
