Now, let’s try a different type of question that can be answered using the compound interest formula. In this example, we will consider a situation in which we know the initial balance, final balance, number of years, and compounding frequency, but we are asked to calculate the interest rate. This type of calculation may be applied in a situation where you want to determine the rate earned when buying and selling an asset (e.g., property) that you are using as an investment.
After setting the above parameters, you will immediately receive your exact compound interest rate. Our investment balance after 10 years therefore works out at $20,720.91. Let’s plug those figures into our formulae and use our PEMDAS order of operations to create our calculation…

For the remainder of the article, we’ll look at how compound interest provides positive benefits for savings and investments. Any interest awarded to your savings account is typically available for use on the same day it’s credited.
Compound interest is calculated by multiplying the initial principal amount by one plus the annual interest rate raised to the number of compound periods minus one. Long-term investing can be a great way to save for your future.Use our compound interest calculator to see how your investments will grow over time. Compound interest is a type of interest that’s calculated from both the initial balance and the interest accumulated from prior periods. If you want to find out how long it would take for something to increase by n%, you can use our rule of 72 calculator. This tool enables you to check how much time you need to double your investment even quicker than the compound interest rate calculator.
Example 1 – basic calculation of the value of an investment
Banks generally provide saving accounts with yearly capitalization of the interest while investments in stocks that pay a dividend have yearly, quarterly or monthly payments. The Rule of 72 is a simpler way to determine how long it’ll take for a specific amount of money to double, given a fixed return rate of return that is compounded annually. It can be used for any investment, as long as there is a fixed rate that involves compound interest. Simply divide the number 72 by the annual rate of return and the result of this is how many years it’ll take.
- With savings and investments, interest can be compounded at either the start or the end of the compounding period.

In other words, current and noncurrent assets compounding interest means reinvesting the interest rather than paying it out, so that in the following period you earn interest on the principal sum plus the previously accumulated interest. Therefore, the more often the interest is added to (capitalized on) the principal amount, the faster your balance grows. The final value after 5 years is $11,041 whereas with simple interest it would have been just $11,000.
How is compound interest calculated?
Note that youshould multiply your result by 100 to get a percentage figure (%). Start by multiply your initial balance by one plus the annual interest rate (expressed as a decimal) divided by the number of compounds per year. Next, raise the result to the power of the number of compounds per year multiplied by the number of years. Subtract the initial balancefrom the result if you want to see only the interest earned. You can use the compound interest equation to find the value of an investment after a specified period or estimate the rate you have earned when buying and selling some investments.
Or, you can compare some of our top-rated options to find out about other popular savings accounts on the market. With most savings accounts, interest is calculated every day on your daily closing balance. The effective interest rate (or effective annual rate) is the rate that gets paid after all the compounding. When compounding of interest takes place, the effective annual rate becomes higher than the overall interest rate.
This is why one can also describe compound interest as a double-edged sword. Putting off or prolonging outstanding debt can dramatically increase the total interest owed. Interest is the cost of using borrowed money, or more specifically, the amount a lender receives for advancing money to a borrower. When paying interest, the borrower will mostly pay a percentage of the principal (the borrowed amount). The concept of interest can be categorized into simple interest or compound interest.
There will be no contributions (monthly or yearly deposits) to keep the calculation simpler. If an amount of $10,000 is deposited into a savings account at an annual interest rate of 3%, compounded monthly, the value of the investment after 10 years can be calculated as follows… Most financial advisors will tell you that compound frequency is the number of compounding periods in a https://accountingcoaching.online/ year. In other words, compounding frequency is the time period after which the interest will be calculated on top of the initial amount. Making regular, additional deposits to your account has the potential to grow your balance much faster thanks to the power of compounding. Ourdaily compounding calculator allows you to include either daily or monthly deposits to your calculation.
Example 2 – complex calculation of the value of an investment
This is because rate at which compound interest grows depends on the compounding frequency, such that the higher the compounding frequency, the greater the compound interest. At year five the gap in return is more than $2,500 while at year ten it is over $15,000 on that same $10,000 initial investment. For a deeper exploration of the topic, consider reading our article on how compounding works with investments. This formula can help you work out the yearly interest rate you’re getting on your savings, investment or loan.

The compounding frequency, which is the time period at which interest is added to the principal, can have a slight positive effect on the effective interest rate versus the nominal annual interest rate. Using shorter compounding periods in our compound interest calculator will easily show you how big that effect is. You get the best effective rate when you have daily compounding (also called continuous compounding) and slightly worse with monthly or yearly compounding.
The Compound Interest Formula
The Rule of 72 is a shortcut to determine how long it will take for a specific amount of money to double given a fixed return rate that compounds annually. One can use it for any investment as long as it involves a fixed rate with compound interest in a reasonable range. Simply divide the number 72 by the annual rate of return to determine how many years it will take to double. These example calculations assume a fixed percentage yearly interest rate. If you are investing your money, rather than saving it in fixed rate accounts,the reality is that returns on investments will vary year on year due to fluctuations caused by economic factors. More frequent compounding periods means greater compounding interest, but the frequency has diminishing returns.

The depreciation calculator enables you to use three different methods to estimate how fast the value of your asset decreases over time.
In an account that pays compound interest, such as a standard savings account, the return gets added to the original principal at the end of every compounding period, typically daily or monthly. Each time interest is calculated and added to the account, it results in a larger balance. With the compound interest formula, the account earns more interest in the next compounding period. If an amount of $5,000 is deposited into a savings account at an annual interest rate of 3%, compounded monthly, with additional deposits of $100 per month(made at the end of each month). The value of the investment after 10 years can be calculated as follows…
