Example Calculation

Let’s look at a practical example:

Principal Amount: $15,000
Annual Interest Rate: 5%
Number of Periods: 36 months

Step 1: Convert annual interest rate to monthly:
Monthly Rate = 5% ÷ 12 = 0.004167

Step 2: Calculate Monthly Payment using annuity formula:
Monthly Payment = (P × r) ÷ (1 − (1 + r)^−n)
= (15,000 × 0.004167) ÷ (1 − (1 + 0.004167)^−36)
≈ $449.22

Step 3: Calculate Total Payment:
Total Payment = Monthly Payment × Number of Months
= $449.22 × 36 ≈ $16,171.92

Step 4: Calculate Total Interest:
Total Interest = Total Payment − Principal
= $16,171.92 − $15,000 ≈ $1,171.92

By using the calculator, you instantly know your monthly obligation, total repayment, and the total interest you’ll pay over 3 years.
