That’s why it’s worth knowing how to calculate compound interest. The most common real-life application of the compound interest formula is a regular savings calculation. Making regular, additional deposits to your account has the potential to grow your balance much faster thanks to the power of compounding.
One Grain of Rice, the folktale by Demi, is centered around a reward where a single grain of rice is awarded on the first day and the number of grains of rice awarded each day is doubled over 30 days. At the end of the month, over 536 million grains of rice would be awarded on the last day. This formula assumes that no additional changes outside of interest are made to the original principal balance.
Putting off or prolonging outstanding debt can dramatically increase the total interest owed. From abacus to iPhones, learn how calculators developed over time. This article about the compound interest formula has expanded and evolved based upon your requests for adapted formulae and

On the other hand, compound interest is the interest on the initial principal plus the interest which has been accumulated. We provide answers to your compound interest calculations and show you the steps to find the answer. You can also experiment with the calculator to see how different interest rates or loan lengths can affect how much you’ll pay in compounded interest on a loan. Let us take the example of a sum of $5,000 that has been deposited for 5 years at an interest rate of 5% to be compounded annually. I hope you found our daily compounding calculator and article useful. At The Calculator Site we love to receive feedback from our users, so please get in contact if you have any suggestions or comments.
- The depreciation calculator enables you to use three different methods to estimate how fast the value of your asset decreases over time.
- On the other hand, compound interest is the interest on the initial principal plus the interest which has been accumulated.
- However, even when the frequency is unusually high, the final value can’t rise above a particular limit.
Assuming that the interest rate is equal to 4% and it is compounded yearly. Find the number of years after which the initial balance will double. As you can see this time, the formula is not very simple and requires a lot of calculations. That’s why it’s worth testing our compound interest calculator, which solves the same equations in an instant, saving you time and effort. In this example you earned $1,000 out of the initial investment of $2,000 within the six years, meaning that your annual rate was equal to 6.9913%.

What is daily compound interest?
The effects of compounding may work in favor of or against an investor depending on their specific financial situation. Hence, if a two-year savings account containing $1,000 pays a 6% interest rate compounded daily, it will grow to $1,127.49 at the end 3 types of financial statements and how to use them of two years. When interest compounding takes place, the effective annual rate becomes higher than the nominal annual interest rate. The more times the
interest is compounded within the year, the higher the effective annual interest rate will be.
Frequently Asked Questions on Compound Interest Calculator
Compound interest has dramatic positive effects on savings and investments. Ancient texts provide evidence that two of the earliest civilizations in human history, the Babylonians and Sumerians, first used compound interest about 4400 years ago. However, their application of compound interest differed significantly from the methods used widely today. In their application, 20% of the principal amount was accumulated until the interest equaled the principal, and they would then add it to the principal. While compound interest grows wealth effectively, it can also work against debtholders. This is why one can also describe compound interest as a double-edged sword.
Will my final balance compounded continuously be higher with daily compounding?
I think pictures really help with understanding concepts, and this situation is no different. The power of compound interest becomes
obvious when you look at a graph of long-term growth. In our article about the compound interest formula, we go through the process of
how to use the formula step-by-step, and give some real-world examples of how to use it. The investing information provided on this page is for educational purposes only.

For example, if you put $10,000 into a savings account with a 4% annual yield, compounded daily, you’d earn $408 in interest the first year, $425 the second year, an extra $442 the third year and so on. After 10 years of compounding, you would have earned a total of $4,918 in interest. Have you noticed that in the above solution, we didn’t even need to know the initial and final balances of the investment? It is thanks to the simplification we made in the third step (Divide both sides by PPP). However, when using our compound interest rate calculator, you will need to provide this information in the appropriate fields.
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 balance
from the result if you want to see only the interest earned. 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 after compounding has been factored in. Calculate compound interest on an investment, 401K or savings account with annual, quarterly, daily or continuous compounding. 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.
