This is different from compound interest, where interest is calculated on on the initial amount and on any interest earned. As you will see in the examples below, the simple interest formula can be used to calculate the interest earned, the total amount, and other values depending on the problem. Compound interest formula. A simpler version of the compound interest formula is B = P( 1 + r) n where B is the final balance, P is the principal, r is the interest rate for 1 or each interest period, and n is the number of payment periods. The principal is the amount of money you deposit that you expect will grow over time.

18 Jun 2018 For example, assume the principal is $100,000, the interest rate is 11 percent and the term is 2 years. The simple interest formula is I = P x R x T  is the compound interest formula where. P = Initial deposit = 5000. r = Interest rate = 0.12. n = Number of times interest is compounded per year = 1. t = Number of years that have passed = 5 Round to the nearest cent or hundredth is . When you know the principal amount, the rate, and the time, the amount of interest can be calculated by using the formula: I = Prt. For the above calculation, you have $4,500.00 to invest (or borrow) with a rate of 9.5 percent for a six-year period of time. Compound interest is the money charged by the lender on the principal and the interests which is accumulated till that time period.

Step 2-Substitute this stuff into the compound interest formula. Step 3-Solve! Divide both sides by 16,000 Take the 120th root of both sides (that means finding ) Subtract 1 from both sides Multiply both sides by 12 The annual interest rate you need is 2.23% By Formula: Interest = Principal * Rate * Time => P = P * R * 5 => R = 1/5 = 0.2 = 20% p.a. Thus for amount to become 4 times, we would need interest = 3 times principal 3*P = P* 0.2 * T => T = 3/0.2 = 15 yrs Also see: Lessons: Basics of Interest Rates and its uses Compound Interest Solvers:
