Example Calculation

Let’s walk through a practical example:

  • Principal Amount: $10,000
  • Annual Interest Rate: 6%
  • Number of Months: 24

Step 1: Calculate Monthly Interest Rate
= 6% ÷ 12 = 0.5% = 0.005 (as decimal)

Step 2: Calculate Monthly Payment
Using the annuity formula:Monthly Payment=P×r1−(1+r)−n\text{Monthly Payment} = P \times \frac{r}{1 - (1+r)^{-n}}Monthly Payment=P×1−(1+r)−nr​

= 10,000 × [0.005 ÷ (1 − (1 + 0.005)^-24)]
≈ $443.21

Step 3: Calculate Total Payment
= Monthly Payment × Number of Months
= 443.21 × 24
≈ $10,637.04

Step 4: Calculate Total Interest
= Total Payment − Principal
= 10,637.04 − 10,000
≈ $637.04

So, using this calculator, you’ll know that for a $10,000 loan at 6% interest over 24 months, your monthly payment is $443.21, total payment is $10,637.04, and total interest is $637.04.
