Simple Interest Formula With Examples Access Calculator Educba Alternatively, you can use the simple interest formula i=prn if you have the interest rate per month. if you had a monthly rate of 5% and you'd like to calculate the interest for one year, your total interest would be $10,000 × 0.05 × 12 = $6,000. the total loan repayment required would be $10,000 $6,000 = $16,000. First of all, take the interest rate and divide it by one hundred. 5% = 0.05. then multiply the original amount by the interest rate. $1,000 × 0.05 = $50. that's it. you have just calculated your annual interest! to get a monthly interest, divide this value by the number of months in a year (12). $50 12 = $4.17.
Simple Interest Definition Formula Examples Cuemath This calculator for simple interest only finds i, the simple interest where p is the principal amount of money to be invested at an interest rate r% per period for t number of time periods. where r is in decimal form; r=r 100. r and t are in the same units of time. calculate interest, solve for i. i = prt. calculate principal amount, solve for p. Simple interest calculations. the following examples will show you how to solve different variables involved in simple interest calculation. example 1. what is the simple interest on a loan of $300 for 4 months at 12% per year? ans. si = p×r×t = 300×(12 100 12)×4 = $12. example 2. Examples of finding the interest earned with the simple interest formula. in many simple interest problems, you will be finding the total interest earned over a set period, which is represented as \(i\). the formula for this is: let’s use an example to see how this formula works. remember that in the formula, the principal \(p\) is the. Simple interest means earning or paying interest only the principal [1]. the principal is the amount borrowed, the original amount invested, or the face value of a bond [2]. on this page, i explain the simple interest formula and provide a simple interest calculator that you can use to solve some basic problems.
