You had to flip through dozens of pages to find the appropriate value of the compound amount factor or present worth factor. It is also worth knowing that exactly the same calculations may be used to compute when the investment would triple (or multiply by any number, in fact). All you need to do is just use a different multiple of P in the second step of the above example.
How Compound Interest Grows Over Time
For instance, we wanted to find the maximum amount of interest that we could earn on a $1,000 savings account in two years. With your new knowledge of how the world of financial calculations looked before Omni Calculator, do you enjoy our tool?

How to use the compound interest calculator?
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.

It’s designed to help users plan their financial future, whether for retirement, saving for a home, or understanding the potential growth of their investments. To compare bank offers that have different compounding periods, we need to calculate the Annual Percentage Yield, also called Effective Annual Rate (EAR). The most comfortable way to figure it out is using the APY calculator, which estimates the EAR from the interest rate and compounding frequency. If you want to roughly calculate compound interest on a savings figure, without using a calculator, you can use a formula calledthe rule of 72.
Interest rate definition
So, for the borrower, the interest rate is the cost of the debt, while for the lender, it is the rate of return. Enter the principal amount, interest rate, time period, and click ‘Calculate’ to retrieve the interest.

Compound Interest Formula
It’ll tell you how much you might earn on your savings,investment or 401k over a period of years and months based upon a chosen number of compounds per year. Calculate compound interest on an investment, 401K or savings account with annual, quarterly, daily or continuous compounding. This variation of the formula works for calculating time (t), by using natural logarithms.
- 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.
- If you plan to get $15,000 in 10 years, you need to know how much interest you will need to earn if you invest $5,000.
- Don’t worry if you just want to find the time in which the given interest rate would double your investment; just type in any numbers (for example, 111 and 222).
- Calculate compound interest on an investment, 401K or savings account with annual, quarterly, daily or continuous compounding.
- However, even when the frequency is unusually high, the final value can’t rise above a particular limit.

Interest can be compounded on any given frequency schedule, from continuous to daily, monthly, quarterly to annually. When calculating compound interest, the number of compounding periods makes a significant difference for future earnings. 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. Don’t worry if you just want to find the time in which the given interest rate would double your investment; just type in any numbers (for example, 111 and 222).
To understand how it does it, let’s take a look at the following example. Within our compound interest calculator results section, you will see either a RoR or TWR figure appear for your calculation. sale of a business Use the tables below to copy and paste compound interest formulas you need to make these calculations in a spreadsheet such as Microsoft Excel, Google Sheets and Apple Numbers.

To see how compound interest differs from simple interest, use our simple interest vs compound interest calculator.
Our calculator allows the accurate calculation of simple or compound interest accumulated over a period of time. Looking back at our example, with simple interest (no compounding), your investment balanceat the end of the term would be $13,000, with $3,000 interest. With regular interest compounding, however, you would stand to gain an additional $493.54 on top.
If you include regular deposits or withdrawals in your calculation, we switch to provide you with a Time-Weighted Return (TWR) figure.

The calculations results given by the compound interest calculator serve only as guide for potential future value.
Below you can find information on how the compound interest calculator works, what user input it accepts and how to interpret the results and future value growth chart. This calculation is valuable if you have the desired outcome in mind. For example, suppose you want to get $10,000 and have an investment opportunity that returns 5% interest. In that case, this calculation will help you determine how much you need to invest initially. As you can see, the interest earned in the example above will continue to grow each year.
$10,000 invested at a fixed 5% yearly interest rate, compounded yearly, will grow to $26,532.98 after 20 years. This means total interest of $16,532.98 anda return on investment of 165%. So, let’s now break down interest compounding https://www.online-accounting.net/ by year,using a more realistic example scenario.

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. The interest rate is commonly expressed as a percentage of the principal amount (outstanding loan or value of deposit). Usually, it is presented on an annual basis, which is known as the annual percentage yield (APY) or effective annual rate (EAR). Compound Daily Interest is a powerful force in the world of finance. It calculates interest on your principal amount, including previously earned interest, on a daily basis.
