Frequently Asked Questions
How is EMI calculated?
EMI = P × r × (1+r)^n / ((1+r)^n - 1), where P = Principal loan amount, r = monthly interest rate (annual rate ÷ 12 ÷ 100), n = total number of months. For example, ₹10 lakh at 8.5% for 20 years gives EMI ≈ ₹8,678 per month.
What is an amortization schedule?
An amortization schedule shows each loan payment split into principal and interest components. In early months, most of the EMI goes toward interest. As the loan progresses, more goes toward reducing the principal. The schedule shows exactly how your loan balance reduces each month.
How can I reduce my home loan interest?
1) Make prepayments whenever possible — even small amounts save significant interest. 2) Choose shorter tenure to reduce total interest (though EMI increases). 3) Negotiate a lower rate after 2-3 years of good repayment history. 4) Balance transfer to a bank offering lower rates. 5) Make an extra EMI payment annually.
What is the 40% EMI rule?
The 40% rule says your total EMI obligations (all loans combined) should not exceed 40% of your monthly take-home income. This ensures you have enough for expenses, savings and emergencies. Banks may approve up to 50-60% of gross income, but 40% is a safer personal finance guideline.
Should I choose shorter or longer loan tenure?
Shorter tenure: Higher EMI but much less total interest paid. Better if you can afford higher monthly payments. Longer tenure: Lower EMI but significantly more total interest. Better for cash flow management. As a rule, try the shortest tenure where EMI stays within 40% of your income.
