Formula Used

The calculation uses the compound interest formula:

A = P(1 + r/n)^(nt)

Where:

A = the future value of the investment/loan, including interest
P = the principal investment amount
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per year
t = the time the money is invested for, in years

The total interest earned is calculated as A - P.

Worked Example

Let's say you deposit $1,000 at an annual interest rate of 5%, compounded monthly for 3 years.

Using the formula:

A = 1000(1 + 0.05/12)^(12×3)

A ≈ 1000(1.004167)^36 ≈ 1161.64

Total interest earned = 1161.64 - 1000 = $161.64

This means your $1,000 deposit would grow to approximately $1,161.64 after 3 years with monthly compounding at 5% APR.

Frequently Asked Questions

What is the difference between simple and compound interest?: Simple interest is calculated only on the original principal amount, while compound interest is calculated on the initial principal and also on the accumulated interest of previous periods.
How often should interest be compounded for maximum growth?: The more frequently interest is compounded, the faster your money grows. However, the difference between daily and monthly compounding is often small for short-term deposits.
Is the interest rate before or after taxes?: The interest rate shown is typically before taxes. The actual amount you receive may be less due to withholding taxes.
Can I use this calculator for loans as well as deposits?: Yes, this calculator can be used for both deposits and loans, though the interpretation of the results will differ (gains vs. payments).
What factors can affect the actual interest rate I receive?: Several factors can affect your actual interest rate, including the bank's prime rate, your credit score, the type of account, and current market conditions.
