About the Loan Calculator

The CalcNest Loan Calculator gives borrowers a complete picture of their loan commitments, monthly cash outflows, and cumulative finance costs. Explore yearly amortization tables to understand how your loan balance decreases over time.

Mathematical Formula

EMI = P × r × (1 + r)^n / ((1 + r)^n - 1) | Balance = Balance - Principal Paid

Calculates monthly debt obligations and models how repayments are allocated between principal reduction and interest fees over the loan tenure.

Variables & Components

P Loan Principal: Total capital borrowed from the financial institution.
r Monthly Interest: Annual interest percentage divided by 1200.
n Tenure (Months): Total agreed repayment months.

Worked Example: ₹5,00,000 Auto Loan at 9% p.a. for 5 Years

Financing a vehicle purchase with a 5-year loan of ₹5,00,000 at 9.0% reducing balance interest rate.

Step-by-Step Calculation

  1. Convert tenure: 5 years = 60 monthly payments
  2. Monthly interest rate: r = 9 / 1200 = 0.0075
  3. Calculate Monthly Installment: EMI = ₹10,379.18 per month
  4. Total Payment = 60 × ₹10,379.18 = ₹6,22,751
  5. Total Finance Charge / Interest = ₹1,22,751
Final Result: Monthly EMI: ₹10,379 | Total Interest: ₹1,22,751 | Total Cost: ₹6,22,751
