How the Calculation Works
EMI Formula (Equated Monthly Instalment):
EMI = P × r × (1 + r)^n / ((1 + r)^n − 1)Where: P = Loan principal (Property price − Down payment), r = Monthly interest rate (Annual rate ÷ 12 ÷ 100), n = Total months (Tenure × 12).
Total Cost of Renting:
Total Rent = Sum of monthly rent for each year, with rent increasing annually by the rent hike rateAdditionally, the savings from not buying (down payment + monthly difference between EMI and rent) are compounded at the investment return rate. The net rent cost = Total rent paid − Investment corpus built.
Net Cost of Buying:
Net Buy Cost = Down Payment + Total EMI Paid + Maintenance + Property Tax − Future Property ValueMaintenance is estimated at 1% of current property value per year and property tax at 0.5%, both growing with appreciation. The opportunity cost of the down payment is also factored — what it could have earned if invested.
Practical Examples
🇮🇳 Rahul from Mumbai
Rahul is considering a ₹75,00,000 flat in Navi Mumbai. He can put 20% down (₹15,00,000), get a loan at 8.5% for 20 years. His current rent is ₹25,000/month with 5% annual increases. Property appreciation: 4%. Investment returns: 10%.
EMI: ₹75L × 80% = ₹60L loan → EMI ≈ ₹52,069/month
Total EMI over 20 years: ≈ ₹1,24,96,560. Add maintenance + tax: ≈ ₹27,89,000. Total buying outflow: ≈ ₹1,67,85,560. Property value after 20 years at 4%: ≈ ₹1,64,33,417. Net buy cost: ≈ ₹18,52,143.
🇮🇳 Priya from Bengaluru
Priya looks at a ₹50,00,000 apartment. 25% down (₹12,50,000), 8.75% interest, 15-year tenure. Rent: ₹18,000/month, 6% annual hike. Appreciation: 3%. Investment returns: 12%.
Loan: ₹37,50,000 → EMI ≈ ₹37,617/month. Total EMI: ≈ ₹67,71,060.
🇬🇧 James from London
James weighs renting at £1,800/month vs buying a £450,000 flat. 15% down, 4.5% mortgage rate, 25 years. Rent increase: 3%. Appreciation: 3%. Investment: 7%.
Mortgage: £382,500 loan → Monthly ≈ £2,127.
🇮🇳 Amit from Jaipur
Amit considers a ₹30,00,000 house. 30% down (₹9,00,000), 9% interest, 15 years. Rent: ₹10,000/month, 4% annual increase. Appreciation: 6%. Investment: 9%.
Loan: ₹21,00,000 → EMI ≈ ₹21,300/month.
What Is a Rent vs Buy Calculator?
A Rent vs Buy Calculator is a financial planning tool that compares the total lifetime cost of renting a home against purchasing one. It accounts for mortgage payments, property appreciation, maintenance costs, rent escalation, and the opportunity cost of your down payment to give you a data-driven answer to one of life's biggest financial questions.
Most people make this decision emotionally — "owning feels secure" or "renting feels like wasting money." But the math tells a more nuanced story. In cities where property prices are extremely high relative to rents (like Mumbai or San Francisco), renting and investing the difference often wins. In markets with strong appreciation and affordable prices, buying tends to come out ahead.
This calculator strips away the guesswork by running the numbers on both scenarios simultaneously, helping you see exactly how each variable — interest rate, rent hike, investment returns — shifts the answer.

Is this tool free to use?
Yes, the Rent vs Buy Calculator is completely free to use with no signup or hidden charges. You can run unlimited comparisons.
How does the calculator determine EMI?
It uses the standard EMI formula: EMI = P × r × (1+r)^n / ((1+r)^n - 1), where P is the loan principal, r is the monthly interest rate, and n is the total number of monthly payments.
What is the opportunity cost of down payment?
The opportunity cost represents what your down payment could have earned if invested elsewhere. The calculator compounds it at the investment return rate you specify over the analysis period.
Does the calculator include maintenance and property tax?
Yes, the calculator estimates annual maintenance at 1% of property value and property tax at 0.5% of property value, both growing with property appreciation.
How is rent increase calculated?
Rent increases annually by the percentage you specify. For example, a 5% annual increase on ₹20,000 rent means you pay ₹21,000 in year two, ₹22,050 in year three, and so on.
What investment return rate should I use?
Use a realistic post-tax return rate. For conservative estimates, 8-10% works for Indian equity mutual funds. For fixed deposits, 6-7% is reasonable. The higher the return rate, the more favourable renting becomes.
Can this calculator be used for properties outside India?
Absolutely. While default values suit Indian users, you can enter any currency amounts and rates. The math works universally for any housing market.
Does property appreciation affect the buy calculation?
Yes. The calculator computes the future property value using your appreciation rate and subtracts it from total buying costs, since the property is an asset you retain.
What loan tenure should I choose?
Most Indian home loans range from 15 to 30 years. A longer tenure lowers EMI but increases total interest paid. The calculator shows the full impact so you can decide what suits your budget.
How accurate is this comparison?
The calculator provides a strong financial framework for comparison. However, real-world costs like stamp duty, registration fees, brokerage, and home insurance are not included. Use results as directional guidance alongside professional advice.
Why does the calculator show net cost of buying as negative sometimes?
A negative net buying cost means the property appreciation and equity gained exceed the total costs paid. This happens when property appreciation rates are high relative to interest rates and maintenance costs.
