How to Calculate Simple Interest

Calculating simple interest is as straightforward as it gets. Multiply the principal amount by the interest rate (as a decimal) and then again by the time period. Here’s the formula: P×r×t.

Example Calculation

Suppose you want to calculate the simple interest on a $3,000 loan at a 4% annual interest rate for 3 years. Here’s the math: 3000×0.04×3 = $360.

Or, if you’re lending $1,200 at a 2% monthly interest rate for 5 months, the calculation would be: 1200×0.02×5 = $120.

Simple Interest Formula

The simple interest formula is your ticket to understanding your financial gains or obligations. Here it is: A = P(1 + rt).

Where:

• A is the total accumulated amount (principal + interest).
• P is the principal amount (your initial investment or loan amount).
• r is the annual interest rate (decimal).
• t is the time period in years.

Practical Examples

Let’s walk through a practical example. Imagine you lend a friend $2,000 at a 6% yearly interest rate for 2 years. Here’s how it works: A = 2000 × (1 + (0.06 × 2)) = 2240.

Your friend will owe you $2,240 in 2 years, with $240 being the interest. For more examples and practice problems, check out MathIsFun.
