How down payment & EMI work together

Down payment is the % you pay upfront. The rest is financed via home loan. Lower DP = higher loan = higher EMI + more total interest.

  1. 01

    Down payment

    Typically 10-20% of property value. RBI caps loan-to-value (LTV) at 90% for ≤ ₹30L; 80% for ₹30-75L; 75% above.

    dp = price × dp_pct ÷ 100
  2. 02

    Loan amount

    Whatever the down payment doesn't cover.

    loan = price − dp
  3. 03

    EMI

    Standard EMI formula on the loan amount.

    EMI = loan × r × (1+r)^n ÷ ((1+r)^n − 1)
FormulaDP = Price × DP% ÷ 100; Loan = Price − DP; EMI = Loan × r × (1+r)^n ÷ ((1+r)^n − 1)Higher DP reduces EMI and total interest but ties up cash that could be invested.

FAQs about down payment & home loans

Common questions about home loan structure, LTV, and EMI strategy.

For properties under ₹30L: minimum 10% down (banks can lend 90%). ₹30L-75L: minimum 20% (80% LTV). Above ₹75L: minimum 25% (75% LTV). These are RBI mandates.

Higher DP wins on total interest. Longer tenure helps cash flow but costs much more. Example on ₹40L loan @ 8.5%: 15y = ₹34L interest; 20y = ₹43L; 30y = ₹70L. Big difference.

Add 7-10% of property value for: stamp duty (5-7%), registration (1%), GST on under-construction (5%), legal fees (₹10K-50K), and home loan processing fee (0.5-1% of loan).

Yes. Section 24: up to ₹2L per year interest deductible (self-occupied). Section 80C: up to ₹1.5L principal repaid is deductible. First-time buyers: extra ₹50K under 80EE.

Generally no for purchase loans (RBI rules limit LTV). However, top-up loans on existing home loans can effectively give you 100% in some cases. Loan-against-property allows up to 80% of property value.

Math: if your post-tax investment return exceeds the post-tax home loan rate, invest. Home loan rate ~8.5% post-tax = ~6%. SIPs returning 12% beat this. But prepayment has psychological benefit (debt-free).

Banks allow up to 40-50% of net income going to EMI. Smart limit: 30-35% for sustainability. Above 45% leaves no buffer for emergencies or other goals.

Yes. Most home loans allow part-prepayments and EMI step-up without penalty (RBI rule for floating-rate). Use bonuses to make annual prepayments — knocks years off tenure.
