Home Down Payment Calculator

RBI loan-to-value (LTV) bands determine the maximum loan and therefore the minimum down payment. Properties up to ₹30 lakh: LTV up to 90%, so 10% minimum down payment. Properties ₹30–75 lakh: LTV up to 80%, so 20% minimum. Properties above ₹75 lakh: LTV up to 75%, so 25% minimum. These are statutory ceilings — your actual offer depends on credit profile and income, and is often 5 percentage points below the LTV cap. On top of this, you need to fund 6–10% of the property value as non-loanable costs (stamp duty + registration + GST on under-construction + brokerage + interiors). So a ₹60 lakh property typically needs ₹15–18 lakh in liquid funds at sanction.

Five line items that the home loan doesn't cover, totalling 6–10% of property value: (1) Stamp duty — 4–7% varying by state, with concessions for women buyers in Maharashtra / Karnataka / Rajasthan / UP. (2) Registration — 1% in most states, capped or fixed at ₹30k in a few. (3) GST — 1% on affordable (under ₹45L) / 5% on other under-construction; ready-to-move is GST-free. (4) Brokerage — typically 1–2% of deal value if you transact via an agent. (5) Interiors / move-in costs — 5–15% of property value if you plan to renovate or fully furnish from scratch. The down payment alone funds only the loan-to-value gap; budget for these on top, or use the home loan eligibility calculator to see the full upfront cheque size.

Three considerations point both ways. Arguments for going above minimum LTV: (1) Lower EMI for the loan tenure, which improves cashflow. (2) Lower total interest paid. (3) Banks often offer a 5–25 bps rate concession for loans with LTV below 70%, which compounds across the tenure. Arguments against: (1) Locking up cash in an illiquid asset that returns ~5–7% (rental yield + capital appreciation, in nominal INR terms) when equity SIPs return 10–14% over comparable horizons. (2) Lost emergency liquidity. (3) Tax deductions under Section 24(b) on home loan interest are valuable for higher-income borrowers in the old regime. Pragmatic rule: pay the minimum to clear the LTV band, deploy the rest in equity SIPs, prepay later when the equity portfolio has compounded.

Depends on the target year. For a 5-year horizon (typical for first-time buyers in their late 20s / early 30s), start the SIP today regardless of where rate cycles or property prices sit — neither is reliably predictable, and 5 years of compounding at 10–12% closes most of the gap between a borrower's starting position and the required down-payment + fees corpus. For longer horizons (7–10 years), equity-heavy allocations are appropriate; for shorter (under 3 years), shift toward hybrid / debt funds to protect against equity drawdown in the goal year.

Goal horizon dictates allocation. For 5+ years out: 70–80% in flexi-cap or large-cap mutual funds + 20–30% in short-duration debt or arbitrage funds. For 3–5 years: 40–60% equity, balance in debt — sequence-of-returns risk in the goal year is real. For under 3 years: predominantly debt funds, FDs, or arbitrage funds — capital protection beats expected return when the horizon is short. A separate consideration: PPF for the secure base if you have unused 80C room (7.10% tax-free, 15-year lock-in — only useful if your purchase timing is beyond the lock-in or you can use the loan/partial-withdrawal facility).

Rough math: every additional year you wait adds 6–8% to the property price (CPI + real-estate-specific inflation) but lets you save more. If your additional annual saving rate is below 6–8% of the target property price, you're falling behind — buy with the smaller down payment now. If your savings rate is above 10% of property price, you're catching up — waiting genuinely shrinks the loan you'll need. Most first-time buyers in major Indian metros find prices outrun their savings rate, which is why buying sooner with a higher LTV usually works out better than waiting. The exception: if a rate cycle peak is imminent and you can wait 6–12 months, locking the loan at a lower rate can swap a few months of price appreciation for years of EMI savings.

It uses the goal-SIP engine — given a target corpus (your down-payment + fees + buffer figure), expected return rate, and years to goal, it solves for the monthly SIP needed. Plug in the down-payment+fees as the target. The "inflation adjust target" toggle, when on, inflates the target to future rupees — useful if your target reflects today's property prices but the actual purchase is years out. Real-estate inflation in major Indian metros has historically run 6–9% per year; use that range as the inflation rate when adjusting.

Four levers. (1) Step-up SIP — start lower and grow 10% annually as salary rises; use the step-up SIP calculator to size this. (2) Stretch the goal year — moving from 5 years to 7 cuts the required monthly SIP by roughly 30%, at the cost of waiting longer to buy. (3) Smaller property — drop to a tier-2 city or smaller area; reduces target proportionally. (4) Higher LTV — use a 90% LTV product on a sub-₹30 lakh property to need only 10% as down payment, plus the 6–10% non-loanable costs. The down-payment-affordability math is genuinely binding for many first-time buyers; an honest trade-off across these levers is more useful than aspirational targets.
