Final Amount

This is the total sum you’ll have at the end of the specified period, including both your initial principal and the interest earned.

Simple vs. Compound Interest: What’s the Difference?

Simple Interest

Simple interest is calculated only on the principal amount. It’s straightforward but less common in real-world financial products.

Formula: Simple Interest = Principal × Rate × Time

Compound Interest

Compound interest is calculated on the initial principal and also on the accumulated interest of previous periods. It’s more common and can significantly impact long-term savings and investments.

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

• A = Final amount
• P = Principal balance
• r = Annual interest rate (in decimal form)
• n = Number of times interest is compounded per year
• t = Number of years

Practical Applications of the Interest Calculator
