Using the Compound Interest Calculator:

Now, let’s get down to business and understand the variables within the Compound Interest Calculator.

Initial Investment: The starting amount you invest or deposit.
Interest Rate: The annual interest rate on your investment.
Compound Interval: annually, semi-annually, quarterly, monthly, bi-weekly, weekly, daily, or continuously.
Investment Duration: The number of years you plan to keep your money invested.
Inflation Rate: An optional parameter accounting for the impact of inflation on your investment.

Formula for Final Balance:

The compound interest formula that calculates your final balance is a mathematical marvel:

Where:

A is the future value of the investment/loan, including interest.
P is the principal investment amount (initial deposit or loan amount).
r is the annual interest rate (as a decimal).
n is the number of times that interest is compounded per unit t. For Annually compounding n=1, monthly compounding n=12, Daily compounding n= 365.
t is the time the money is invested or borrowed for, in years.

Formula for Buying Power After Adjusting for Inflation:

To account for the impact of inflation, the adjusted formula for buying power is:

Where:

BP is the buying power of the final balance after adjusting for inflation.
A is the future value of the investment/loan.
i is the annual inflation rate (as a decimal).
t is the time the money is invested or borrowed for, in years.

Example:

Let’s consider an example:

Initial Investment: $10,000
Interest Rate: 5%
Compound Interval: Monthly
Investment Duration: 15 years
Inflation Rate: 2%

Using the compound interest formula, the final balance would be:

Final Balance: A= $21137.04

And the buying power after adjusting for inflation would be:

Buying Power of Final Balance after Adjusting for Inflation: BP = $15705.13

This example demonstrates how the Compound Interest Calculator can project your investment growth and buying power over time, considering both compound interest and inflation.
