Simple interest is of two types ordinary simple interest and exact simple interest. In ordinary simple interest, a year is considered of 365 days while calculating the interest while in exact simple interest, a year is considered 366 days if it is a leap year.

The formula for simple interest helps you find the interest amount if the principal amount, rate of interest and time periods are given. Multiply the account balance by the interest rate for a select time period. The result is rate formula in simple interest the amount of simple interest the account earns in that time period. On the other hand, the compound interest is the interest which is calculated on the principal and the interest that is accumulated over the previous tenure.

Compound interest is often a factor in business transactions, investments, and financial products intended to extend for multiple periods or years. Typically, simple interest is used for loans of a single period or less than a year. If you don’t let the principal payments vary, as in an interest-only loan (zero principal payment), or by equalizing the principal payments, the loan interest itself doesn’t compound. If you make partial payments to a simple interest loan, the payment will be applied to interest first, and any remainder will be used to reduce the principal. For example, let’s say that a student obtains a simple interest loan to pay for one year of college tuition. Along with entering the interest rate, adjust the compound frequency to daily, monthly or annually to see how each period affects the yield.

If you hadn’t converted here, you would have found the interest for 4 years, which would be much higher. So, always make sure to check that the time is in years before applying the formula. Simple interest is the interest paid only on the principal, whereas, compound interest is the interest paid on both principal and interest compounded in regular intervals.

Compound Annual Growth Rate (CAGR)

While you may not consider $310 a huge difference, this example is only a three-year loan; compound interest piles up and becomes oppressive with longer loan terms.

Generally, the higher the number of compounding periods, the greater the amount of compound interest. There can be a big difference in the amount of interest payable on a loan if interest is calculated on a compound basis rather than on a simple basis. On the positive side, the magic of compounding can work to your advantage when it comes to your investments and can be a potent factor in wealth creation. The interest rate is the rate of interest that is charged or earned during a specified time period. If you want to compute the sum of the interest paid over a specified period, all you need to do is multiply the monthly interest by the adequate number of months or years.
