So, if you have any comments or suggestions, I would love to hear from you. The concept of compound interest, or ‘interest on interest’, is that accumulated interest is added back onto your principal sum, withfuture interest being calculated on both the original principal and the already-accrued interest. Here you can set how often the interest is added to (capitalized on) your balance (principal). Interest Earned – How much interest was earned over the number of years to grow. Beginning Account Balance – The money you already have saved that will be applied toward your savings goal.
As you compare the compound interest line tothose for standard interest and no interest at all, you can see how compounding boosts the investment value. Use the compound interest rate calculator to compute the precise interest rate that is applied to an initial balance that reaches a certain surplus with a given compound frequency over a certain period.

The effective annual rate (also known as the annual percentage yield) is the rate of interest that you actually receive on your savings or investment aftercompounding has been factored in. Now that you understand how powerful compound interest can be, let’s break down how it’s calculated. Compound interest works by adding earned interest back to the principal. This generates additionalinterest in the periods that follow, which accelerates your investment growth. We’ve discussed what compound interest is and how it is calculated.
What is the effective annual interest rate?
Future Value (FV), equal to the sum of the initial balance and the surplus. After setting the above parameters, you will immediately receive your exact compound interest rate. You may choose to set the frequency as continuous, which is a theoretical limit of recurrence of interest capitalization. In this case, interest compounds every moment, so the accumulated interest reaches its maximum value. To understand the math behind this, check out our natural logarithm calculator, in particular the The natural logarithm and the common logarithm section. Compound interest is the addition of interest to the existing balance (principal) of a loan or saving, which, together with the principal, becomes the base of the interest computation in the next period.
How does the compound interest rate calculator work?

- This compounding effect causes investments to grow faster over time, much like a snowball gaining size as it rolls downhill.
- Compound interest occurs when interest is added to the original deposit – or principal – which results in interest earning interest.
- Looking back at our example from above, if we were to contribute an additional $100 per month into our investment,our balance after 20 years would hit the heights of $67,121, with interest of $33,121 on total deposits of $34,000.
- You may choose to set the frequency as continuous, which is a theoretical limit of recurrence of interest capitalization.
- Just enter your beginning balance, the regular deposit amount at any specified interval, the interest rate, compounding interval, and the number of years you expect to allow your investment to grow.
When interest compounding takes place, the effective annual rate becomes higher than the nominal annual interest rate. The more times theinterest is compounded within the year, the higher the effective annual interest rate will be. You can include regular withdrawals within your compound interest calculation as either a monetary withdrawal or as a percentage of interest/earnings.

Annual Interest Rate (ROI) – The annual percentage interest rate your money earns if deposited. ______ Addition ($) – How much money you’re planning on depositing daily, weekly, bi-weekly, half-monthly, monthly, bi-monthly, quarterly, semi-annually, or annually over the number of years to grow. When you invest in the stock market, you don’t earn a set interest rate, but rather a return based economic profit vs accounting on the change in the value of your investment. If you left your money in that account for another year, you’ll earn $538.96 in interest in year two, for a total of $1,051.63 in interest over two years. You earn more in the second year because interest is calculated on the initial deposit plus the interest you earned in the first year.
