Example Calculation

Suppose you have the following loan details:

Principal: $10,000
Annual Interest Rate: 6%
Term: 24 months

Step 1: Calculate Monthly Interest Rate
Monthly Rate = Annual Rate ÷ 12 ÷ 100 = 6 ÷ 12 ÷ 100 = 0.005

Step 2: Calculate Monthly Payment
Monthly Payment = P × r ÷ (1 − (1 + r)^−n)
= 10,000 × 0.005 ÷ (1 − (1 + 0.005)^−24)
≈ $443.21

Step 3: Calculate Total Payment
Total Payment = Monthly Payment × Months = 443.21 × 24 ≈ $10,637

Step 4: Calculate Total Interest
Total Interest = Total Payment − Principal = 10,637 − 10,000 = $637

So, for this loan, your monthly payment will be $443.21, with a total interest of $637 over 24 months.
