How this is calculated

Formula

EMI = P × i × (1 + i)ⁿ ÷ ((1 + i)ⁿ − 1)

P
= loan amount
i
= monthly rate = annual rate ÷ 12 ÷ 100
n
= number of instalments = years × 12

With your numbers

  1. 1Monthly ratei = r ÷ 12 ÷ 1008.50% ÷ 12 ÷ 100 = 0.007083
  2. 2Instalmentsn = years × 1220 × 12 = 240
  3. 3EMIP × i × (1 + i)ⁿ ÷ ((1 + i)ⁿ − 1)₹50,00,000 → ₹43,391 a month
  4. 4Each monthinterest = balance × i; principal = EMI − interestMonth 1: interest ₹35,417, principal ₹7,974
Monthly EMI₹43,391
  • Early instalments are mostly interest, because interest is charged on the whole outstanding balance. That is also why a prepayment early in the loan saves the most.
  • A prepayment that keeps the EMI and shortens the tenure always saves more interest than one that keeps the tenure and lowers the EMI: the larger instalment keeps paying down principal faster.
  • The rate is held constant for the whole tenure, and no prepayment fee is deducted. Check your loan agreement for either.

₹50 lakh over 30 years instead of 20

The EMI falls from ₹43,391 to ₹38,446, ₹4,945 a month less. Total interest rises from ₹54,13,879 to ₹88,40,443: ₹34,26,564 more for the lower instalment.

₹5 lakh prepaid after instalment 24

Keeping the EMI and shortening the loan saves ₹14,57,301 of interest and closes it 45 months early. Asking the lender to lower the EMI instead (to ₹38,864) saves ₹4,77,894.

Common mistakes

  • Comparing a flat rate with a reducing-balance rate

    On the table's loan, 8.5% charged on the reducing balance costs ₹54,13,879 of interest. The same 8.5% quoted flat, on the original amount for all 20 years, costs ₹85,00,000. Home loans are quoted reducing; some other loans are not.

    Loan conventions
  • Assuming a prepayment saves the same either way

    Lenders can apply a prepayment by shortening the tenure or by lowering the EMI, and the saving differs: in the example above, ₹9,79,407 more by keeping the EMI. Ask which one your lender will do.

    Prepayment calculator
  • Counting all the interest as a tax deduction

    For a self-occupied home, Section 22 (formerly 24(b)) allows at most ₹2,00,000 of interest a year, under the old regime only. On the table's loan, interest exceeds that in 14 years of 20; the excess is not deductible. Principal repaid falls inside the shared ₹1,50,000 Section 123 (formerly 80C) limit.
