# Simple Interest Calculator, Calculate SI over days, months, years

In real life, most interest calculations involve compound Interest. It is better for savers/investors to have a higher EAR, though it is worse for borrowers to have a higher EAR. A nominal interest rate does not take into account any fees or compounding of interest. That’s why the effective annual interest rate is an important financial concept to understand. You can compare various offers accurately only if you know the effective annual interest rate of each one.

When there is less demand for credit or money, they lower rates in order to entice more borrowers. With that said, banks and credit unions still have to adhere to their reserve requirements, and there is a maximum amount that they can lend out at any time. It’s worth noting that we also have other options for investments involving calculation of future values and returns. Should you wish to work out the rate of interest you’ve
received on an investment based upon a current and future value, you can use our calculator for compound annual growth rate. If you’re
wondering how much money you might stand to make from a future investment, try calculating the internal rate of return.

However, the annual effective interest rate, calculated
under the assumption that interest payments are reinvested, would be 10.38%. This is because the interest paid at every quarter is also subject multi-step income statement vs single step to the
interest rate of 2.5% for every quarter. Before you use the formulas or the
calculator, you should determine whether the interest rate in question is a
simple or a compound interest rate.

For example, if you were considering a mortgage loan for \$200,000 with a 6% interest rate, your annual interest expense would amount to \$12,000, or a monthly payment of \$1,000. The interest rate of a loan or savings can be “fixed” or “floating.” Floating rate loans or savings are normally based on some reference rate, such as the U.S. Federal Reserve (Fed) funds rate or the LIBOR (London Interbank Offered Rate). Normally, the loan rate is a little higher, and the savings rate is a little lower than the reference rate.

For instance, administrative fees that are usually due when buying new cars are typically rolled into the financing of the loan instead of paid upfront. APR is a more accurate representation than the interest rate when shopping and comparing similar competing. On the other hand, annual percentage yield (APY) is the interest rate that is earned at a financial institution, usually from a savings account or Certificate of Deposit (in the U.S.). For more information or to do calculations involving APR, please visit the APR Calculator. Simple interest is calculated as a percentage of principal only, while compound interest is calculated as a percentage of the principal along with any accrued interest. As a result of this compounding behavior, interest earned by lenders subsequently earns interest over time.

• Use our calculator or the formulas
introduced in this article to determine the type of rate that you need.
• The more frequently interest is compounded within a time period, the higher the interest will be earned on an original principal.
• Though broadly used across the financial sector, there are several downsides of EAR.
• This is useful for those who have the habit of saving a certain amount periodically.
• For this reason, it’s sometimes also called the “quoted” or “advertised” interest rate.

As established above, a loan this size would total \$12,500 after five years. That’s \$10,000 on the original principal plus \$2,500 in interest payments. Compound interest calculations can get complex quickly because it requires recalculating the starting balance every compounding period. Simple interest works in your favor as a borrower, since you’re only paying interest on the original balance. That contrasts with compound interest, where you also pay interest on any accumulated interest. For example, let’s say you take out a \$10,000 loan at 5% annual simple interest to repay over five years.

Payments are applied to both principal and interest, extending the length of the loan and increasing the interest paid over time.

For instance, an 8% interest rate for borrowing \$100 a year will obligate a person to pay \$108 at year-end. As can be seen in this brief example, the interest rate directly affects the total interest paid on any loan. Generally, borrowers want the lowest possible interest rates because it will cost less to borrow; conversely, lenders (or investors) seek high interest rates for larger profits. Interest rates are usually expressed annually, but rates can also be expressed as monthly, daily, or any other period.

## Effective Annual Interest Rate: Definition, Formula, and Example

Usually, it is presented on an annual basis, which is known as the annual percentage yield (APY) or effective annual rate (EAR). In the U.S., credit scores and credit reports exist to provide information about each borrower so that lenders can assess risk. A credit score is a number between 300 and 850 that represents a borrower’s creditworthiness; the higher, the better. Good credit scores are built over time through timely payments, low credit utilization, and many other factors.

The 6% interest rate is then used to calculate a new annual payment of \$12,300. To calculate the APR, simply divide the annual payment of \$12,300 by the original loan amount of \$200,000 to get 6.15%. Interest is the cost you pay to borrow money or the compensation you receive for lending money.

## Everyday Calculation

You will need your principal loan amount, interest rate and your loan term in order to calculate the overall interest costs. The simple interest rate is an annual rate
that is simply divided by its payment frequency without adjustment for compound
interest. Compound interest is a type of interest that’s calculated from both the initial balance and the interest accumulated from prior periods. Generally, compound interest is defined as interest that is earned not solely on the initial amount invested but also on any further interest. In other words, compound interest is the interest on both the initial principal and the interest which has been accumulated on this principle so far.

The per annum interest rate refers to the interest rate over a period of one year with the assumption that the interest is compounded every year. For instance, a 5% per annum interest rate on a loan worth \$10,000 would cost \$500. A per annum interest rate can be applied only to a principal loan amount. The average consumer pays the prime rate plus another rate based on their riskiness as a borrower. Be sure to use the interest rate in your calculations—not the annual percentage yield. For example, on auto, home, and personal loans, you gradually pay down your balance over time, and you usually end up with a lower balance each month.

As you pay back your principal balance each month, you also have to pay back interest, which does add to the overall cost of your loan. There are two primary types of interest, and it’s important to know the difference between the two when it comes to calculating your rate. The Bankrate loan interest calculator only applies to loans with fixed or simple interest. When used correctly, it can help you determine the total interest over the life of your loan, as well as the average monthly interest payments. Similar to the market for goods and services, the market for credit is determined by supply and demand, albeit to a lesser extent. When there exists a surplus of demand for money or credit, lenders react by raising interest rates.

For industries that want to downplay costs, nominal rates are best. Suppose, for instance, you have two loans, and each has a stated interest rate of 10%, in which one compounds annually and the other compounds twice per year. Even though they both have a stated interest rate of 10%, the effective annual interest rate of the loan that compounds twice per year will be higher. Credit card interest rates may be negotiable, but it’s up to the card issuer.

However, some assets use simple interest for simplicity — for example bonds that pay an interest coupon. To take advantage of compounding you would need to reinvest the dividends as added principal. Under this formula, you can manipulate “t” to calculate interest according to the actual period. For instance, if you wanted to calculate interest over six months, your “t” value would equal 0.5.

In our article about the compound interest formula, we go through the process of
how to use the formula step-by-step, and give some real-world examples of how to use it. However, if Derek has a marginal tax rate of 25%, he will end up with \$239.78 only because the tax rate of 25% applies to each compounding period. It will take 9 years for the \$1,000 to become \$2,000 at 8% interest. This formula works best for interest rates between 6 and 10%, but it should also work reasonably well for anything below 20%. That process is called amortization, and an amortization table helps you calculate (and shows you) exactly how much interest you pay every month.
