- Total Payment (Principal + Interest)
- Total Interest Payable
🧮 Steps to Use:
- Enter your Loan Amount (e.g., $20,000).
- Provide the Annual Interest Rate (e.g., 6%).
- Enter the Loan Term in years (e.g., 5).
- Click Calculate.
- Instantly view the monthly EMI and total loan cost.
📊 Loan Calculation Formula
The core of the loan calculator is the PMT formula, which is the same one used in Excel:
🔢 EMI Formula:
EMI = [P × r × (1 + r)^n] / [(1 + r)^n – 1]
Where:
- P = Principal loan amount
- r = Monthly interest rate (Annual Rate / 12 / 100)
- n = Loan term in months (Years × 12)
This formula accurately calculates the fixed monthly payment required to pay off a loan.
💡 Example Calculation
Let’s say you’re planning to take a loan with the following parameters:
- Loan Amount: $20,000
- Annual Interest Rate: 6%
- Loan Term: 5 Years
Step-by-step:
- Monthly interest rate = 6 / 12 / 100 = 0.005
- Number of payments = 5 × 12 = 60 months
- EMI =
20000×0.005×(1+0.005)6020000 × 0.005 × (1 + 0.005)^6020000×0.005×(1+0.005)60 / (1+0.005)60–1(1 + 0.005)^60 – 1(1+0.005)60–1
≈ $386.66
- Total Payment: $386.66 × 60 = $23,199.60
- Total Interest: $23,199.60 – $20,000 = $3,199.60
This helps you understand the cost of borrowing and plan accordingly.
