📌 What is a Loan Calculator?

A Loan Calculator is an online tool that helps you calculate your loan repayment details in just a few seconds. It provides:

• EMI (monthly installment amount)
• Total interest payable
• Total repayment amount (Principal + Interest)

By entering just three values:

1. Loan Amount
2. Interest Rate (%)
3. Loan Tenure (months/years)

👉 Example: If you take a loan of ₹5,00,000 at 10% interest rate for 5 years, the loan calculator will show you:

• EMI = ₹10,624
• Total Interest = ₹1,37,467
• Total Payment = ₹6,37,467

📌 Why Loan Calculation is Important?

1. Financial Planning – Helps you decide if you can afford the EMI.
2. Comparing Loans – Check which bank or lender gives better terms.
3. Avoid Over-Borrowing – Prevents you from taking a loan beyond your budget.
4. Transparency – Know exactly how much interest you are paying.
5. Time-Saving – No need to do manual calculations.

🛠️ Manual Method: Loan Calculation Formula

The formula for calculating EMI is: EMI=P×r×(1+r)n(1+r)n−1EMI = \frac{P \times r \times (1+r)^n}{(1+r)^n – 1}EMI=(1+r)n−1P×r×(1+r)n​

Where:

• P = Loan Amount (Principal)
• r = Interest Rate per month (Annual Rate ÷ 12 ÷ 100)
• n = Loan Tenure in months

Example:

Loan Amount (P) = ₹5,00,000
Interest Rate = 10% per annum = 0.10/12 = 0.0083
Tenure = 5 years = 60 months EMI=500000×0.0083×(1+0.0083)60(1+0.0083)60−1EMI = \frac{500000 \times 0.0083 \times (1+0.0083)^{60}}{(1+0.0083)^{60} – 1}EMI=(1+0.0083)60−1500000×0.0083×(1+0.0083)60​

👉 Final Answer: EMI = ₹10,624

✅ This matches the online calculator result.
