This calculator computes your monthly loan EMI and generates a detailed, month-by-month repayment schedule (amortization table). It shows exactly how your monthly payment is split between reducing the loan principal and paying the bank interest over the entire tenure.
- 1
Loan Amount (₹): Enter the total amount you wish to borrow.
- 2
Interest Rate (%): Enter the annual interest rate offered by the lender.
- 3
Tenure (Years): Enter the loan duration in years.
- The Concept: When you take a loan, you repay it in Equated Monthly Installments (EMIs). In the early years, a larger portion of your EMI goes toward paying off the interest because the outstanding loan amount is high. As the principal reduces, the interest component decreases, and more of your EMI goes toward principal repayment.
- The Formula:
- EMI = [P × r × (1 + r)^n] / [(1 + r)^n - 1]
where P is the Loan Amount, r is the monthly interest rate (Rate / 12 / 100), and n is the tenure in months (Years × 12).
- For each month:
- Monthly Interest = Outstanding Principal × r
- Monthly Principal Repayment = EMI - Monthly Interest
- New Outstanding Principal = Outstanding Principal - Monthly Principal Repayment
For example, you take a home loan of ₹30,00,000 at an 8.5% interest rate for 20 years:
- Monthly interest rate (r) = 8.5 / 12 / 100 = 0.007083
- Total months (n) = 20 × 12 = 240
- Monthly EMI = [30,00,000 × 0.007083 × (1.007083)^240] / [(1.007083)^240 - 1] = ₹26,035
- Month 1 Breakdown:
- Interest component = ₹30,00,000 × 0.007083 = ₹21,250
- Principal component = ₹26,035 - ₹21,250 = ₹4,785
- Remaining outstanding balance = ₹30,00,000 - ₹4,785 = ₹29,95,215
- Month 2 Breakdown:
- Interest component = ₹29,95,215 × 0.007083 = ₹21,216
- Principal component = ₹26,035 - ₹21,216 = ₹4,819
- Remaining outstanding balance = ₹29,95,215 - ₹4,819 = ₹29,90,396
- Over 20 years, your total payments will equal ₹62,48,337, consisting of ₹30,00,000 principal and ₹32,48,337 in total interest.
