The answer is your interest rate… Free calculator to find the interest rate as well as the total interest cost of an amortized loan with fixed monthly payback amount. Also learn more about interest cost, experiment with other interest and loan calculators, or explore many more calculators on topics such as finance, math, fitness, and health. Simple Interest Equation (Principal + Interest) A = Total Accrued Amount (principal + interest) P = Principal Amount. I = Interest Amount. r = Rate of Interest per year in decimal; r = R/100. R = Rate of Interest per year as a percent; R = r * 100. t = Time Period involved in months or years. Your interest payments will be $5 per year no matter how many years the initial sum of money stays in a bank account. This calculator can be used to solve various types of simple interest problems. The calculator will print easy to understand step-by-step explanation . Interest rate is the amount charged by lenders to borrowers for the use of money, expressed as a percentage of the principal, or original amount borrowed; it can also be described alternatively as the cost to borrow money. For instance, an 8% interest rate for borrowing $100 a year will obligate a person to pay $108 at year end.

## Find the principal. Annual rate of interest = 11 % = 11 \% = 1 1 % equals, 11, percent Period = 3 = 3 = 3 equals, 3 years Total interest = 825 = 825 = 8 2 5 equals, 825 rupees

However, with a little math and some common sense, anyone can quickly calculate an investment's interest To calculate your annual percentage rate, or APR, look at the finance charges on your most recent credit card statement. Then divide your finance charges by the total balance on the card. Multiply this result by 1200 to get your APR. Find the principal. Annual rate of interest = 11 % = 11 \% = 1 1 % equals, 11, percent Period = 3 = 3 = 3 equals, 3 years Total interest = 825 = 825 = 8 2 5 equals, 825 rupees Compound Interest is calculated on the initial payment and also on the interest of previous periods. Example: Suppose you give \$100 to a bank which pays you 10% compound interest at the end of every year. After one year you will have \$100 + 10% = \$110, and after two years you will have \$110 + 10% = \$121. Interest rate can be for any period not just a year as long as compounding is per this same time unit. For example, your stated rate is 9% per quarter compounded monthly. Enter 9% and 3 (for 3 months per quarter to get P = 3%, the effective rate per month. Side Note: the effective rate calculation tells us How to calculate annual percentage yield. The calculation of the annual percentage yield is based on the following equation: APY = (1 + r/n) n – 1. where: r - the interest rate; n - the number of times the interest is compounded per year; As you have already learned what APY is, you can use this formula to calculate the annual percentage yield by yourself.
