Lenders will usually tell you the maximum home loan you're eligible for. That number is built around their risk appetite, not your monthly comfort — and the two are often quite different. Before you fix a budget or start house-hunting, it helps to work out what you can afford, not just what you qualify for.
Start with the 40% rule, then stress-test it
A common starting point: keep your total EMIs (home loan plus any existing personal loan, car loan or credit-card EMI) under roughly 40% of your monthly take-home pay. Many lenders use a similar band when calculating eligibility. But "the bank will approve it" and "I'll sleep well paying it" aren't the same test — a 40% EMI load leaves little room if your income dips or a large expense shows up.
A more conservative approach many financial planners suggest: model your EMI at 30–35% of take-home pay if you can, and separately check that you can still save at least 15–20% of your income after the EMI and essential expenses.
The down payment trade-off
A larger down payment reduces your loan amount, your EMI and your total interest — but only if it doesn't drain your emergency fund. As a rule of thumb, keep at least 6 months of essential expenses in reserve after making your down payment. If reaching 20% down means emptying your safety net, consider a smaller down payment and building the fund back up over the following year instead.
Tenure: the lever most people get wrong
A longer tenure lowers your EMI but increases total interest paid — sometimes substantially. A useful middle path: choose the longest tenure that keeps your EMI comfortable, but make voluntary part-prepayments whenever you have a bonus or windfall. This gives you a lower mandatory EMI (useful in a lean year) while still letting you close the loan faster when you're flush.
- Prepaying early in the loan term saves more interest than prepaying later, because interest is front-loaded in EMI schedules.
- Check whether your lender charges a prepayment penalty — for floating-rate home loans to individual borrowers, Indian regulations generally prohibit this, but it's worth confirming for your specific loan.
- Even small, regular part-prepayments (once or twice a year) can shave years off a 20-year loan.
Don't forget the costs outside the EMI
Budget separately for: stamp duty and registration (varies by state, often 5–7% of property value), processing fees, home insurance, society maintenance, and a furnishing/move-in buffer. These are one-time or recurring costs that don't show up in an EMI calculator but absolutely show up in your bank balance.
A simple pre-application checklist
- Total EMI (existing + new) stays under ~35–40% of take-home pay.
- Down payment funded without touching your 6-month emergency reserve.
- Budget set aside for stamp duty, registration and move-in costs.
- Tenure chosen for comfort, with a plan to part-prepay opportunistically.
- Rates and offers compared across at least 2–3 lenders before committing.
