Nothing changes with time, so we didn’t include a field that would specify your loan’s duration. In the following sections, we will also show you some examples of simple interest calculations. Let’s start with learning how to use this simple interest calculator. Simple interest is interest that is only calculated on the initial sum (the “principal”) borrowed or deposited.
Simple interest definition and simple interest formula
New calculations would have to be done for variable interest rates when rates change or different compounding intervals. Variable interest rates – also known as floating interest rates – are not fixed, but are dependent on market performance. If the market is volatile, interest rates also change dramatically during the entire course of the term.
- Variable interest rates – also known as floating interest rates – are not fixed, but are dependent on market performance.
- This new formula breaks out the amount borrowed/lent (PV) from the interest paid/received (PV × r × t).
- By reinvesting the dividends, you can increase your shareholdings and boost your potential for long-term capital appreciation.

- Unfortunately, even if you had such an amount, currently, there are only a few existing financial products that are based on the concept of perpetuities.
- While returns may be lower than riskier investments, fixed deposits offer guaranteed interest, making them a popular choice for those seeking stable, predictable income.

This new formula breaks out the amount borrowed/lent (PV) from the interest paid/received (PV × r × t). I hope this calculator and article has helped you with calculating the interest on your savings or loan. If you have any questions or suggestions for improvements, please do drop me a line. Simple interest is a form of interest commonly used for transactions such as auto loans, student loans or personal loans. Now you know what is simple interest and how to calculate its value. So it’s high time you become familiar with more complex concepts of financial mathematics.

This simple interest calculator can find the total principal plus interest, principal only and interest only. It can also calculate the simple interest rate, or time period in days, weeks, months, quarters and years. Input any three variables of total amount, principal, interest rate or time period and the calculator can find the missing variable. You calculate the simple interest earned in a savings account by multiplying the account balance by the interest rate by the time period the money is in the account.
For the following 4 years, the value of the house decreases in value by a simple interest rate of 0.18\% per annum. To find the final value of the investment you can now add the interest to the principal amount.

About the Simple Interest Formula Used by This Calculator
For a quick example, consider a $10,000 loan at 5% interest repaid over five years. Our calculator will compute any of these variables given the other inputs.
You can also use this tool to compute monthly payments on an interest-only loan. Just enter the interest percentage, and you’ll know how much that loan costs. By contrast, most checking and savings accounts, as well as credit cards, operate using compound interest.
Note that r and t are in the same units of time, typically years. Simple interest is used when you pay back a loan because you only pay interest on the current value of the loan, not the previous interest that has accrued. A savings account is an example of when simple interest is not used. Assuming you leave prior interest payments in the account, you will receive interest on the original value plus the prior interest payments.
You put it into a bank account with a 5% annual interest rate. No matter how much time passes, you’ll still have $1 million on that account. Interest is the cost you pay to borrow money or the compensation you receive for lending money. You might pay interest on an auto loan or credit card, or receive interest on cash deposits in interest-bearing accounts, like savings accounts or certificates of deposit (CDs). Please keep in mind that these calculations are based on a fixed annual interest rate for illustrative purposes. In reality, investment returns are not always consistent and can fluctuate from year to year due to changes in market conditions, interest rates, inflation, and various economic factors.
