At 6% simple interest, $1,000 earns $60 per year. Over 2 years, you'd earn a total of $120, bringing your balance to $1,120. Simple interest is calculated only on the original $1,000 principal, so the interest earned each year remains the same $60 regardless of how long you hold the investment.

Yes, many personal loans, auto loans, and short-term lending agreements use simple interest calculations. This is actually advantageous for borrowers because you only pay interest on the original amount borrowed, not on accumulated interest. Making extra payments on a simple interest loan directly reduces the principal and future interest charges.

The formula is I = P × R × T, where P is the principal ($1,000), R is the annual interest rate as a decimal (0.06 for 6%), and T is time in years (2). So I = 1000 × 0.06 × 2 = $120. The total amount after 2 years would be the original $1,000 plus $120 interest, equaling $1,120.
