📝 Step-by-Step Instructions

• Choose between 1 to 30 years.

4. Click “Calculate EMI”

• The calculator instantly computes:

  • ✅ Monthly EMI (the amount you’ll pay every month)

  • ✅ Total Interest (extra amount paid to the lender)

  • ✅ Principal (original loan amount)

  • ✅ Total Payment (principal + interest)

5. Understand the Visuals

• A donut chart shows a clear breakdown:

  • Pink: Principal

  • White: Interest

• Hover over the chart for percentage-based details.

💡 Tips & Notes

• Lower interest rates reduce your monthly burden.

• Longer tenure reduces EMI but increases total interest paid.

• The tool uses the standard EMI formula:

  EMI=P×r×(1+r)n(1+r)n−1EMI = P \times r \times \frac{(1 + r)^n}{(1 + r)^n – 1}EMI=P×r×(1+r)n−1(1+r)n​

  • P = Principal

  • r = Monthly Interest Rate

  • n = Number of Monthly Installments

📊 Chart Features

• Interactive tooltips: Shows dollar amount and percentage on hover.

• Dynamic legend: Matches color coding for interest and principal.

• Automatically updates with every calculation.
