How is simple interest calculated in farm finance?

• A. Interest = Principal × rate
• B. Interest = Principal × rate × time
• C. Interest = Principal × time ÷ rate
• D. Interest = Principal + rate × time

Answer: (C)

Simple interest grows with three pieces: how much money you started with, the interest rate, and how long that money sits invested. The standard way to calculate it is I = P × r × t, where P is the principal, r is the annual rate (as a decimal), and t is the time in years. For example, if you invest 1,000 at 5% for 3 years, the interest earned is 1,000 × 0.05 × 3 = 150, so you’d have 1,150 after three years. The idea is that interest should rise in direct proportion to each of these factors. Using division by the rate or adding the rate to the principal doesn’t reflect how simple interest accumulates over time.
