What is Compound Interest?
Compound interest is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods. It differs from simple interest, where interest is calculated solely on the principal amount.
How Does Compound Interest Work?
Compound interest grows at a faster rate than simple interest because it calculates interest on the accumulated interest over time. This means the amount of interest earned increases each period.
There are many different places you can save your money with various compounding periods. For example, you could save it in a savings account, a Roth IRA, or a traditional IRA. You could also save it in a certificate of deposit (CD) or annuity.
Example of Compound Interest Calculation:
For instance, if you invest $1,000 at an annual interest rate of 5%, compounded annually for 5 years, the calculation would be:
- Year 1: $1,000 x 5% = $50 (Interest)
- Year 2: ($1,000 + $50) x 5% = $52.50 (Interest)
- And so on…
How To Calculate Daily Compound Interest
To calculate daily compound interest, use the formula A = P(1 + r/n)^(nt), where A is the final amount, P is the principal, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the number of years. Plug in the values and solve for A.
How To Calculate Interest Rate Per Month
To calculate the interest rate per month, divide the annual interest rate by 12. For example, if the annual interest rate is 6%, the monthly interest rate would be 0.5%.

How To Calculate Annual Interest Rate
To calculate the annual interest rate, divide the total interest paid by the principal amount and multiply it by the number of periods within a year. This formula is commonly used for loans and investments, providing an accurate measure of the annual interest rate.
Examples Of Interest Compounding
Compound interest means you earn money on the amount you saved or invested, plus on any interest you’ve already gotten. The more often your interest is calculated and added to your account, the more money you make. Here’s how it works in different situations:
- Savings Accounts: You put money in the bank, and the bank gives you interest. If they calculate interest once a year, you’ll get interest on your first year’s interest during the second year. So, your money grows more each year because you’re earning interest on a bigger amount.
- Certificates of Deposit (CDs): This is money you leave in the bank for a set time, and the bank pays you more interest. They might calculate your interest in different ways, affecting how much you get in the end.
- Loans: When you borrow money, you have to pay interest. The way they calculate your interest can make a big difference in how much you end up paying back in total.
In all these cases, you’re making money not just on your original amount but also on the interest that keeps getting added to it. This cycle continues, and over time, it can lead to you earning or owing much more.
Why Use A Compound Interest Calculator
A compounding calculator is a handy tool for several reasons:
- No Hard Math: Calculating compound interest by hand is complicated. This tool does the math for you accurately and quickly, so you don’t have to worry about making mistakes.
- Planning Your Money: Knowing how compound interest will affect your savings, investments, or loans is essential. This calculator shows how your money will grow or how much a loan will cost you over time, helping you with your financial plans.
- Choosing Between Options: If you’re considering different ways to invest your money, this tool can show you which might make you the most. It uses your starting amount, interest rate, and time to show you the future balance.
- Setting Goals: When you have financial targets, like buying a house or retiring comfortably, the calculator helps you figure out how much you need to save or invest regularly to reach your goal on time.
- Smart Decisions: This tool helps you see the long-term effects of your financial choices. You can check whether it’s better to start saving now or later or how different loan terms will affect your repayments.
- Learning Tool: It’s also great for learning more about money matters. By trying out different scenarios, you can see how saving a little bit now can lead to big returns later because of compound interest.
Compound Interest Formula
The compound interest formula calculates the interest earned on an investment or loan that is compounded over time. The formula considers the principal amount, the interest rate, the number of compounding periods per year, and the period of the investment or loan.
The formula is:
A = P(1 + r/n)^(nt)
Where:
A = the future value of the investment or loan, including interest P = the principal amount (the initial investment or loan amount), r = the interest rate (expressed as a decimal), n = the number of times the interest is compounded per year t = the period (in years) of the investment or loan
To use the formula, you would plug in the values for P, r, n, and t and solve for A. For example, if you invest $1,000 at an annual interest rate of 5%, compounded quarterly for five years, the formula would be:
A = 1000(1 + 0.05/4)^(4*5) A = $1,283.35
Your investment would be worth $1,283.35 after five years, with $283.35 in interest earned.

Who Benefits From Compound Interest?
Compound interest benefits lenders, borrowers, and investors by accruing on both the initial principal and accumulated interest. Lenders, like banks, earn more compared to simple interest. Borrowers gain if they invest borrowed money at higher rates. Investors enhance returns through reinvestment in avenues like stocks or mutual funds, leveraging the compounding effect. Overall, it empowers individuals to increase wealth over time.

Triple Compounding: The Power of Tax-Deferral
Now that you understand how compound interest grows, learn how to speed up your savings account’s compound annual growth rate. Here’s how triple compounding with tax-deferred growth works with savings accounts:
- First, the initial investment earns compounding interest on your principal.
- Second, the principal amount then earns compounded interest on your interest earned.
- Finally, the initial principal earns interest on the money you usually lose to taxes.
Your annual interest rate compounds faster than any bank account, including savings, money market accounts, and CDs.
