Interest is also what a bank pays you when you put money in savings account or CD. The interest rate is usually shown as a percentage, such as 4%. Car loans or auto loans use simple interest to calculate the interest. The borrower agrees to pay the money back, plus a flat percentage of the amount borrowed.
- CAGR is extensively used to calculate returns over periods for stocks, mutual funds, and investment portfolios.
- The higher the interest rate and the more times an account compounds, the higher the yield will be.
- You plan to repay the loan in 3 years in one lump sum, with profits you make after someone buys your business.
- Simple interest can be advantageous for borrowers because of its relatively lower cost of money.
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.
Our simple interest calculator calculates monthly payments on an interest-only loan. Just provide the interest percentage, and you’ll know how much that loan rate formula in simple interest costs. Simple interest is a method of interest that always applies to the original principal amount, with the same rate of interest for every time cycle.
Use this free savings calculator to understand how your money can grow over time. Simple interest affects your mortgage amortization or how your mortgage payment is allocated. At the start of your mortgage, most of your payment covers the interest charges. On the other hand, credit cards have compounded interest, often compounded daily.

It considers the costs and how it affects the yearly cost of borrowing the money, considering everything the lender charges. In general parlance, Interest refers to the additional amount paid for obtaining monetary assistance from the lender. In finance terms, when we borrow some amount from any bank or financial institution, we have to repay that amount along with some additional amount for availing of that facility. Suppose after college you want to start a business creating a cool new app. To fund all the costs involved, you borrow $500,000 for 3 years from a wealthy aunt, paying 5% simple interest.
Using The BA 2+ Plus Date Function to Calculate the Exact Number of Days
The time must be in years to apply the simple interest formula. If you are given months, use a fraction to represent it as years. If you want to assume that interest from the previous periods influences the original amount, you should apply compound interest. 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.

One should remember that when calculating simple interest, the Rate of Interest and Time Period of the loan need to be symmetrical. If the interest rate is expressed per annum, one should also express the number of periods annually. On the other hand, if the Time period is monthly or quarterly, one should convert the Interest rate accordingly to match the monthly or quarterly frequency. The Rule of 72 helps you estimate how long it will take your investment to double if you have a fixed annual interest rate. For example, if your interest rate is 4%, divide 72 by 4. It will take roughly 18 years for your investment to double in value.
Investments may also offer a simple interest return as a dividend. To take advantage of compounding you would need to reinvest the dividends as added principal. Since simple interest is calculated only on the principal, it is easier to determine than compound interest. Simple interest is based on the original principal amount of a loan or deposit. Simple interest is better for borrowers because it doesn’t account for compound interest. On the other hand, compound interest is a key to building wealth for investors.

Simple Interest (S.I) is the method of calculating the interest amount for some principal amount of money.
A perpetuity is a specific type of an annuity that has no end. In other words, we could say that perpetuity is a stream of payments that continues forever (indefinitely).

However, with our calculators, you won’t feel the difference.
Understanding these terms can help you understand how much you earn when you leave savings or investments in place over time, and how much it costs when you repay a loan over time.

Use this savings calculator to compare other contribution amounts and yields. A key difference between compound Interest and simple interest lies in the way their respective interest is calculated.

Simple Interest Formulas and Calculations:
Suppose you borrow $10,000 at a 10% annual interest rate with the principal and interest due as a lump sum in three years. Using a simple interest calculation, 10% of the principal balance gets added to your repayment amount during each of the three years. That comes out to $1,000 per year, which totals $3,000 in interest over the life of the loan. Simple interest is an interest charge that borrowers pay lenders for a loan.
The additional money we are required to pay in addition to the money borrowed is the simple interest. Mortgage rates help cover the lending cost to borrowers, but the interest isn’t compounded. You pay interest only on the remaining principal balance each month instead of paying increasing interest charges. Simple interest grows based only on the money you deposit or invest (called the principal). With compound interest, you earn based on the principal plus the interest you’ve already earned.
What is Interest Rate Formula?
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. For a short-term personal loan, a personal loan calculator can be a great way to determine in advance an interest rate that’s within your means. For longer-term loans, this calculator may also be of help. Lowering the interest rate, shortening the loan term, or prepaying principal also has a compounding effect. This type of interest usually applies to automobile loans or short-term loans, although some mortgages use this calculation method.
