Buying a house is a big financial decision, and planning the right budget is crucial to avoid future financial stress. Whether you're a first-time homebuyer or looking for an upgrade, knowing how much you can afford helps in making a well-informed decision. This guide will help you calculate the right budget for buying a house in a simple and practical way.
1. Assess Your Income and Monthly Expenses
Before deciding on a house budget, you must analyze your financial situation:
- Total monthly income – Include salary, rental income, business profits, or any other earnings.
- Fixed expenses – Rent, groceries, transportation, education fees, and medical expenses.
- Savings and investments – Emergency funds, mutual funds, fixed deposits, and other savings.
- Debt obligations – Existing home loans, personal loans, car loans, or credit card EMIs.
- Lifestyle expenses – Travel, entertainment, dining out, and shopping.
Rule of Thumb: The 28/36 Rule
- House expenses (EMI, property tax, insurance) should not exceed 28% of your monthly income.
- Total debts (including the home loan) should not exceed 36% of your monthly income.
For example, if your monthly income is ₹1,00,000, then:
- Maximum home-related expenses = ₹28,000
- Maximum total debt obligations = ₹36,000
2. Check Your Home Loan Eligibility
Most buyers rely on home loans to purchase a house. Banks decide loan eligibility based on:
- Income stability – A steady income from a job or business.
- Credit score – A score above 750 increases approval chances.
- Existing liabilities – More loans reduce your eligibility.
- Down payment capability – Most banks offer up to 80% of the property value as a loan. You must pay at least 20% as a down payment.
- Age of the applicant – Younger applicants get longer loan tenure, while older applicants may have limited tenure options.
- Co-applicant option – Adding a spouse or family member as a co-applicant can increase loan eligibility.
Loan Eligibility Calculation
If your monthly salary is ₹80,000, banks may approve a loan where EMI is up to ₹32,000 (considering the 40% EMI rule). Based on a 7% interest rate for 20 years, you may get a loan of around ₹40-45 lakh.
3. Consider the Down Payment and Additional Costs
Apart from the loan, you need funds for:
- Down payment (usually 20% of property cost)
- Stamp duty & registration charges (5-7% of property value)
- Interior & furniture setup
- Maintenance charges (in case of apartments or gated communities)
- Legal fees & documentation charges
- Brokerage fees (if applicable)
- Home insurance (recommended for protection)
- Parking and clubhouse charges (for apartments)
For example, if the property costs ₹60 lakh:
- Down payment = ₹12 lakh (20%)
- Registration & stamp duty = ₹3-4 lakh
- Additional costs (interiors, legal, etc.) = ₹3-5 lakh
- Total upfront cost = ₹18-21 lakh
4. Select the Right Loan Tenure & EMI Plan
Choosing the right loan tenure impacts your monthly EMI and interest paid:
- Shorter tenure = Higher EMI, lower interest paid
- Longer tenure = Lower EMI, higher total interest paid
- Balance EMI with your income & future expenses.
5. Factor in Future Financial Stability
Your budget should consider:
- Job stability and expected salary growth.
- Family expenses (education, medical, lifestyle costs).
- Emergency savings (3-6 months' expenses in reserve).
- Possible prepayment of loan (to reduce interest burden).
- Retirement planning – Ensure home purchase does not impact future savings.
6. Compare Locations & Property Prices
Property rates vary based on location, facilities, and future development plans. Before finalizing:
- Compare per sq. ft. price in different areas.
- Check infrastructure development like metro, highways, hospitals, schools.
- Consider resale value and rental income potential.
- Avoid over-budgeting for luxury amenities unless necessary.
- Research government subsidies or tax benefits for first-time homebuyers.
7. Hidden Costs to Consider Before Buying
Many buyers overlook additional costs that impact their budget:
- Society maintenance charges – Monthly or yearly fees for security, amenities, etc.
- Home renovation and furnishing – Painting, modular kitchen, lighting, etc.
- Moving costs – Shifting expenses, packers & movers.
- Property tax – Annual payments depending on the area and property size.
- Utility deposits – Electricity, water, gas connection charges.
- GST on under-construction properties – Applicable for new projects.
8. Make a Smart Buying Decision
- Use online EMI calculators to finalize your budget.
- Check offers from multiple banks and negotiate interest rates.
- Consider ready-to-move vs. under-construction properties.
- If required, opt for joint loans with spouse to increase loan eligibility.
- Plan for home maintenance expenses to avoid financial burden after purchase.
