Simple Interest vs Compound Interest: Understanding the Differences

When it comes to financial dealings, such as investments or loans, understanding how interest is calculated can significantly impact your outcomes. will dive deep into the concepts of simple interest and compound interest, illustrating their distinctions with practical examples.

What's Common?

Interest payments serve as a fee for borrowing funds from lers in financial markets. These fees are pd by borrowers to lers at the of loan terms, typically expressed as percentages based on the principal amount borrowed.

Simple Interest: A Fixed Amount

Simple interest is calculated using a static principal amount; it does not adjust over time. The total interest accrued does not get added back into the principal sum.

Example:

Imagine an investor deposits $2,000 in a four-year term deposit with a simple interest rate of 12 annually:

Compound Interest: Growing Amounts

Compound interest involves a variable principal amount that grows over time as the added interest is reinvested. The annual interest earned is then compounded into the principal sum for subsequent calculations.

Example:

Consider investing $2,000 at an annual 12 rate with annual compounding:

Simple vs Compound Interest: Highlighting the Difference

To visually illustrate these differences, we've created an interactive Excel spreadsheet that you can access to compare simple and compound interest outcomes in various scenarios.

Continuous Compounding: An Infinite Process

Continuous compounding takes interest calculation to the next level by recalculating it continuously throughout the year. This method uses Euler’s number e ≈ 2.7183 to represent the rate at which interest accumulates:

Formula:

A = P times e^r times t

Where A is the future value, P is the principal amount, r is the annual interest rate, and t is time in years.

: A Comparative Look

In our example with continuous compounding at a 12 annual rate over four years for $2,000:

Setting the number of compound periods to an extremely high value e.g., 100,000 in the Excel model validates this figure.
