To calculate simple interest in Excel, you need to use a simple formula. In this formula, you need to have the principal amount, interest rate, and term period of the interest and then you need to multiply all of these with each other to get the final interest amount in the result.
Although it is very easy to understand and calculate simple interest, real-life scenarios are usually based on compound interest. Compound interest is an interest calculation approach with a significant difference. You assume that the interest amount is added to the principal balance after each period. Thus, the interest amount will be higher due to that increase at the end of every compounding period.
It can be beneficial when comparing different loan or investment options. For example, you can use the formula to compare the total cost of borrowing between different lenders or the interest earned on other savings accounts. A simple interest formula is a valuable tool for making wise financial decisions.
By understanding the concepts of simple interest, compound interest, and interest rate, you can accurately calculate the amount of interest you will need to pay back on a loan or the amount of money you will earn on an investment over time.
In this scenario, Steve has borrowed $10,000 from a bank at an interest rate of 5% annually for five years. We can use the simple interest formula to calculate the total interest that he will need to pay. Additionally, we can determine the outstanding amount due after five years by adding the Principal amount to the total interest accrued.
Given that Sam has applied for a home loan of $20,000 with an interest rate of 6% for 12 months, and is required to make monthly installments to repay the loan, we can use the amortization method to calculate the simple interest that Sam will need to pay.
Given that Maryland Industries Ltd. borrowed $15,000 long-term from a corporate bank with an annual interest rate of 10%, we can calculate the total amount (including simple interest) that they must pay at the end of the tenure. To solve this problem, we need to use the standard simple interest formula.
The standard simple interest formula uses 360 days as the value of a year, while the exact simple interest formula uses the precise number of days in a year (365 or 366 for leap years).
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.

Our Savings Calculator is a free spreadsheet that is simple to use and much more powerful than most online calculators that you'll find. It will estimate the future value of your savings account with optional periodic deposits. It also includes a yearly table that lets you add specific annual deposits that may be different from year to year. You can also choose to randomize the annual interest rates within the Min/Max values you specify so you can get an idea of what a fluctuating market might do to your savings.
Estimate the interest earned in your savings account. Include regular monthly deposits and/or an annual deposit. This simple to use Excel spreadsheet includes a table showing the interest earned each year.
The versions for OpenOffice and Google Spreadsheets were created using the simpler version of the calculator shown on the left. It doesn't include the random interest rate feature, but you can manually enter different rates for each year in the interest rate column.
Some loan calculations can be very simple, and the purpose of the simple loan calculator spreadsheet below is to demonstrate this with Excel. Unlike many of our other mortgage and loan calculators, our Simple Loan Calculator uses just the basic built-in financial formulas to calculate either the payment (using the PMT formula), the interest rate (using the RATE formula), the loan amount (using the PV formula), or the number of payments (using the NPER formula).
What is displayed above shows that for a given amount of money (principal), say $5000, invested at the interest rate of 5 percent per year for 15 years, using the COUNTA function to calculate the interest generated, that is, =C2*C3*C4 the answer is $3,750. It is possible to verify this formula by manually doing the calculation as shown below:
Alternatively, you can still calculate the simple interest by simply typing the formula above into the cell on the right of the row you are interested in. Hit the enter key when you finish typing, and the result will show.
Unless you are an accounting graduate, financial analyst or an experienced investor, it might be a bit difficult to grasp the concept from specialized financial books and manuals. The aim of this article is to make it easy : ) You will also learn how to use a compound interest formula in Excel and create a universal compound interest calculator for your own worksheets.
In very simple terms, compound interest is the interest earned on interest. More precisely, compound interest is earned on both the initial deposit (principal) and the interest accumulated from previous periods.
Perhaps, it might be easier to start with simple interest that is calculated only on the principal amount. For example, you put $10 into a bank account. How much will your deposit be worth after one year at an annual interest rate of 7%? The answer is $10.70 (10 + 10*0.07 = 10.70), and your earned interest is $0.70.
To understand the idea of compound interest better, let's begin with a very simple example discussed at the beginning of this tutorial and write a formula to calculate annual compound interest in Excel. As you remember, you are investing $10 at the annual interest rate of 7% and want to know how yearly compounding increases your savings.
As you remember, 1% is one part of a hundred, i.e. 0.01, so 7% is 0.07, and this is how percentages are actually stored in Excel. Keeping this in mind, you can verify the result returned by the formula by performing a simple calculation of 10*(1+0.07) or 10*1.07 and make sure that your balance after 1 year will be $10.70 indeed.
To find the amount of earned interest, simply compute the different between the future value (balance) and the present value (initial investment). In our case, the formula in B9 is as simple as:
Enter the above formula in an empty cell, and it will output $2,979.69 as the result (which is perfectly inline with the result of the math calculation performed in the monthly compound interest example).
Clicking the View Report button generates a "Summary Report" as well as "Savings Balance" that provides the detailed info on the amount of additional contributions, earned interest and balance for each year.
Compound interest calculator by Money-ZineThe online calculator from Money-Zine is much simpler compared to Bankrate's one. It asks you to specify only 3 values: the principal investment, interest rate and duration. As soon as you supply these numbers and click the Calculate button, it will show you all types of compound interest rate (daily, weekly, monthly, annual, etc.) as well as the future values with a corresponding compounding.
Compound interest calculator by MoneySmartThis is a really nice online compound interest calculator run by Australian Securities and Investments Commission. It lets you input all relevant factors that determine the future value of your investment and outputs the result as a graph. By hovering over a certain bar in the graph, you can see the summary info for that particular year.
This is how you calculate compound interest in Excel and outside it :) I hope at least one compound interest formula discussed in this article has proved helpful to you. Anyway, I thank you for reading and hope to see you on our blog next week!

I'm looking for one formula in an Excel spreadsheet that calculates and shows the daily compounded interest and shows the daily balance of principal plus accumulated interest. I've done a spreadsheet to calculate each day's interest, but I had to use a second formula to add that daily interest to the principal to calculate the next day's interest. So, I can only drag down the interest column one row and then drag down the principal column one row and keep alternating between them all the way down. I don't know if it's possible to drag downward the daily interest column to see the interest calculated each day, because the day's interest has to be added to the previous day's principal before calculating the new day's interest. I'm sorry I'm not explaining this very well. Perhaps it would be better to show what I have, and somebody can show me how to get daily interest and principal columns in one formula.
A B C D E
1 Date Rate n Daily Interest Principal
2 11/20/2023 0.0585 365 $300,000.00
3 11/21/2023 0.0585 365 48.08 [E2*B3/C3] $300,048.08 [E2 + D3]
4 11/22/2023 0.0585 365 48.09 [E3*B4/C4] $300,096.17 [E3 + D4]
I can of course drag all the way down columns A, B, & C, but to calculate the daily interest in column D, I can only drag it down to row 5, then before I can calculate the next day's compounded interest, I have drag down column E to row 5; and then alternate dragging columns D and E down one row at a time. Is it possible to calculate the daily compounded interest for a certain future date and also know the principal and compounded interest total on that date--without having to calculate two formulas and alternate between the two one row at a time?
Thanks so much for taking the time to help me!
