Enter your principal amount, annual interest rate, times compounded per year, and the number of years into the calculator to determine the future value of your investment.

Compound Interest Calculation Formula

The following formula is used to calculate the future value of an investment with compound interest:

Future Value = Principal * (1 + Rate /

 Times Compounded)^(Times Compounded * Years)

Variables:

  • Future Value is the amount of money accumulated after interest ($)
  • Principal is the initial amount of money invested ($)
  • Rate is the annual interest rate (%)
  • Times Compounded is the number of times interest is compounded per year
  • Years is the number of years the money is invested

To calculate the future value, multiply the principal by one plus the rate divided by the number of times compounded, raised to the power of the number of times compounded multiplied by the number of years.

What is Compound Interest?

Compound interest refers to the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods. This effect can cause wealth to grow exponentially over time, making it a powerful tool for investors.

How to Calculate Compound Interest?

The following steps outline how to calculate the future value using the given formula:


  1. First, determine the principal amount you are investing.
  2. Next, determine the annual interest rate and convert it to a decimal.
  3. Identify how many times the interest will be compounded per year.
  4. Determine the number of years the investment will grow.
  5. Use the formula: Future Value = Principal * (1 + Rate / Times Compounded)^(Times Compounded * Years).
  6. Calculate the future value by plugging in the values.
  7. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge:

Principal Amount = $10,000

Annual Interest Rate = 5%

Times Compounded Per Year = 4

Number of Years = 10

FAQ

1. What is principal amount?

The principal amount is the initial sum of money invested or loaned, on which interest is calculated.

2. How does compound interest differ from simple interest?

Simple interest is calculated on the principal only, while compound interest is calculated on the principal plus any interest that has been added to it over time.

3. How often should I use the compound interest calculator?

It's helpful to use the compound interest calculator whenever you are planning to make an investment or if you want to track the growth of your current investments.

4. Can this calculator be used for different compounding frequencies?

Yes, you can adjust the times compounded per year field to match any compounding frequency to calculate the future value accordingly.

5. Is the calculator accurate?

The calculator provides an estimate of your investment's future value based on the inputs provided. For exact figures, it’s best to consult with a financial advisor or use professional financial software.
