In this scenario, understanding how the simple interest formula and compound interest formula calculate interest will help you program the feature correctly. In simple words, the interest rate is the rate at which the amount is charged by the lender over principle landed by the lender. The interest rate is directly proportional to risk as there is risk involved when a lender lends an amount to the borrower. If the length of the loan is five months and he’s paying you simple interest of 3.5 percent per month to borrow the additional $3,000, your interest income equals $525. Simple interest is used only for loans and investments of less than one year. If the time is longer than one year, compound interest applies instead. The formula for compound interest, including principal sum, is: A = P (1 + r/n) (nt) Compound Interest = Total amount of Principal and Interest in future (or Future Value) less the Principal amount at present called Present Value (PV). PV is the current worth of a future sum of money or stream of cash flows given a specified rate of return . Continuing with the simple interest example, Interest Compounded Annually Amount = P (1+r/100) t. Compound Interest = Total amount – Principal. Rate of interest (R) = [ (A/P) 1/ t − 1] %.
