Rent vs Buy: How to Compare the Real Cost
Comparing rent with a mortgage payment leaves out much of the decision.
A renter pays for housing without building home equity. A buyer can build equity, but may also face mortgage interest, a down payment, purchase costs, property taxes, insurance, maintenance and eventual selling costs.
The answer can also change simply because the household stays in the property for a different number of years. A useful comparison therefore needs to follow both scenarios over time.

The short answer
Renting and buying should be compared using total financial outcomes over the same time period — not simply rent against a mortgage payment. A useful comparison can include:
Renting
- starting rent
- future rent changes
- renter costs
- money not used for a down payment
- investment return assumptions
Buying
- down payment and purchase costs
- mortgage principal and interest
- property taxes and insurance
- maintenance
- home-value assumptions
- selling costs and remaining balance
The time horizon connects all of these variables. A result is only as useful as its assumptions.
Rent is not directly comparable with a mortgage payment
A mortgage payment contains two economically different pieces: interest and principal.
Interest is a borrowing cost. Principal reduces the mortgage balance and increases the homeowner’s equity, assuming the home’s value does not fall by an offsetting amount. Treating the full mortgage payment as a housing “cost” therefore distorts the comparison.
Treating rent as the renter’s only financial effect can also be incomplete, if the renter retains and invests money that would otherwise have gone toward a down payment or higher ownership costs.
Why comparing ₹30,000 rent with a ₹30,000 mortgage doesn’t work
Two payments of the same size look equal on a bank statement. But the renter pays rent plus applicable renter costs, while the owner pays mortgage interest, property costs, maintenance and eventual transaction costs — and simultaneously builds equity through principal repayment.
The correct comparison is not which payment has the smaller number today. It is where each scenario leaves the household after the same period of time.
A rent-vs-buy example with real numbers
Every figure below comes from the Rent vs Buy engine using these assumptions, all of which you can change in the calculator:
| Assumption | Value |
|---|---|
| Home price | ₹60,00,000 |
| Down payment | ₹12,00,000 (20%) |
| Mortgage | ₹48,00,000 at 8% over 20 years |
| Starting monthly rent | ₹25,000 |
| Annual rent increase | 4% |
| Annual home-value change | 4% |
| Maintenance | 1% of home value per year |
| Selling costs | 3% of sale price |
| Renter investment return | 6% |
| Time horizon | 10 years |
Illustrative scenario — not a market forecast, and not current conditions in any country.
Where each scenario stands after 10 years
Total rent paid
₹36,01,832
Renter ending position
₹48,43,522
Buyer net equity
₹53,05,872
Buying ahead
₹4,62,350
| Buying scenario at the horizon | Amount |
|---|---|
| Estimated home value | ₹88,81,466 |
| Remaining mortgage balance | − ₹33,09,150 |
| Selling costs | − ₹2,66,444 |
| Net equity after a sale | ₹53,05,872 |
| Total ownership costs paid | ₹67,38,261 |
Under these assumptions, buying ahead by approximately ₹4,62,350 after 10 years. Change the assumptions and the result can reverse — the sections below show exactly how much.
Buying creates equity — but equity is not the same as profit
Home value minus the remaining mortgage gives gross equity; subtracting selling costs gives estimated net sale proceeds. Here that is ₹88,81,466 − ₹33,09,150 − ₹2,66,444 = ₹53,05,872.
A homeowner can hold substantial equity even when buying has not produced a better financial result than renting, because equity has to be compared against the initial cash invested, the interest paid, maintenance, taxes, insurance, transaction costs and the alternative use of that money.
What happens to the down payment if you rent instead?
The model assumes the renter keeps the ₹12,00,000 that would have gone into a down payment, plus any monthly difference, and invests it at 6%. After 10 years that account is worth ₹48,43,522, which is why the renter’s position is not simply “zero minus rent paid.”
Investment return is an illustrative assumption, not a guaranteed or forecast return.
How long you stay can completely change the answer
| Time in home | Renting position | Buying position | Difference |
|---|---|---|---|
| 3 years | ₹21,89,356 | ₹20,77,038 | −₹1,12,318 |
| 5 years | ₹28,97,095 | ₹28,79,692 | −₹17,403 |
| 7 years | ₹36,44,790 | ₹37,72,348 | +₹1,27,558 |
| 10 years | ₹48,43,522 | ₹53,05,872 | +₹4,62,350 |
| 15 years | ₹70,53,270 | ₹85,01,399 | +₹14,48,129 |
Short holding periods make purchase and selling costs proportionally more important — there are fewer years over which to spread them. Longer periods give the buyer more time to repay principal and potentially build equity, but also expose both scenarios longer to rent changes, maintenance, property-value changes and investment-return assumptions.
What does “break even” mean in rent vs buy?
The break-even point is the first point in the model where one scenario’s calculated financial position catches or overtakes the other. It is not a guaranteed future date — it depends entirely on the assumptions entered.
Under these assumptions the model puts the crossover in year 6.
Home-price growth can change the result dramatically
| Assumed annual home-value change | Buyer net equity | Rent-vs-buy difference |
|---|---|---|
| 0% | ₹25,10,850 | −₹23,32,672 |
| 2% | ₹37,85,397 | −₹10,58,124 |
| 4% | ₹53,05,872 | +₹4,62,350 |
| 6% | ₹71,13,583 | +₹22,70,062 |
The 0% row matters. Property values do not always rise, and a model that quietly assumes they do can make buying look stronger than the evidence supports. Small changes in a long-term growth assumption materially change the comparison.
Illustrative assumptions — not forecasts.
Future rent matters too
| Annual rent increase | Total rent paid | Rent-vs-buy difference |
|---|---|---|
| 0% | ₹30,00,000 | −₹2,61,641 |
| 3% | ₹34,39,164 | +₹2,67,449 |
| 5% | ₹37,73,368 | +₹6,67,320 |
A rent-vs-buy result should not quietly assume rent stays unchanged forever. Over ten years the difference between flat rent and 5% annual increases is ₹7,73,368 of rent paid.
The mortgage rate can move the result
| Mortgage rate | Monthly payment | Rent-vs-buy difference |
|---|---|---|
| 7% | ₹37,214.35 | +₹10,43,187 |
| 8% | ₹40,149.12 | +₹4,62,350 |
| 9% | ₹43,186.85 | −₹1,31,292 |
Illustrative rates — not current mortgage rates.
A larger down payment changes more than the mortgage payment
| Down payment | Cash upfront | Monthly payment | Rent-vs-buy difference |
|---|---|---|---|
| 10% | ₹6,00,000 | ₹45,167.76 | +₹3,07,819 |
| 20% | ₹12,00,000 | ₹40,149.12 | +₹4,62,350 |
| 30% | ₹18,00,000 | ₹35,130.48 | +₹6,16,881 |
A larger down payment reduces borrowing but commits more cash to the property at the beginning — cash the renting scenario would otherwise keep invested. “Bigger down payment is automatically better” is therefore not a valid rent-vs-buy conclusion. The Down Payment Calculator works through the trade-off in more detail.
The renter’s assumed investment return matters too
| Assumed investment return | Renter ending position | Rent-vs-buy difference |
|---|---|---|
| 0% | ₹31,36,429 | +₹21,69,442 |
| 4% | ₹41,87,875 | +₹11,17,996 |
| 7% | ₹52,09,456 | +₹96,416 |
A model that assumes the renter invests spare capital can produce a very different result from one that assumes the renter simply spends it. This assumption should never be hidden, which is why the calculator exposes it as an editable field.
Illustrative return assumptions — not forecasts.
Which assumptions changed the result most?
The calculator’s sensitivity analysis varies one assumption at a time around the baseline and reports how the rent-vs-buy difference moves:
| Assumption varied | Lower value | Baseline | Higher value |
|---|---|---|---|
| Home-price growth | 3 → −₹3,31,079 | 4 → +₹4,62,350 | 5 → +₹13,27,495 |
| Investment return | 5 → +₹8,02,298 | 6 → +₹4,62,350 | 7 → +₹96,416 |
| Rent increase | 3 → +₹2,67,449 | 4 → +₹4,62,350 | 5 → +₹6,67,320 |
| Maintenance (% of value) | 0.5 → +₹9,40,933 | 1 → +₹4,62,350 | 1.5 → −₹16,233 |
The assumptions with the widest spread are the ones your decision actually depends on. If a small change in one of them reverses the answer, the headline number is less decisive than it looks.
Don’t rely on one forecast
| Scenario | Renting position | Buying position | Difference |
|---|---|---|---|
| Scenario A — cautious | ₹53,22,104 | ₹25,10,850 | −₹28,11,255 |
| Scenario B — baseline | ₹48,43,522 | ₹53,05,872 | +₹4,62,350 |
| Scenario C — stronger growth | ₹48,43,522 | ₹71,13,583 | +₹22,70,062 |
The purpose is sensitivity testing, not picking the scenario you prefer. If the conclusion survives the cautious scenario, it is more robust than one that only holds under optimistic growth.
Maintenance is easy to underestimate
Home maintenance is irregular — one year may be inexpensive, another may contain a major repair. For long-term comparisons this model uses an annual assumption expressed as a percentage of home value (1% here) rather than trying to predict specific repairs. That percentage is an editable assumption, not a rule.
Buying and selling are not free transactions
Depending on country and transaction, costs can include purchase taxes or duties, legal and conveyancing costs, lender fees, inspections, registration, agent or brokerage costs and selling costs. Transaction costs matter most when comparing shorter ownership periods, because there are fewer years over which to spread them — visible in the 3-year row of the time-horizon table above.
Ownership costs continue after the purchase
A mortgage is not the entire cost of owning a home. Depending on jurisdiction and property, ongoing costs may include property tax, home insurance, association or service fees and maintenance. The calculator has fields for each so they enter the comparison rather than being assumed away.
Some parts of the decision cannot be reduced to money
Financial calculations cannot measure flexibility, the desire to relocate, job uncertainty, control over the property, renovation freedom, commute preferences, family plans, tolerance for maintenance responsibility, or the value placed on housing stability.
A financially stronger scenario is not automatically the personally better housing choice.
Six rent-vs-buy comparisons that can mislead you
- Rent vs the full mortgage payment — mortgage principal builds equity.
- Rent vs mortgage interest only — ownership has other costs.
- Assuming home prices always rise — property values can stagnate or fall.
- Assuming rent never rises — long-term rent may change.
- Ignoring the down payment's alternative use — committed cash could otherwise stay invested.
- Ignoring selling costs — a future sale can materially change net proceeds.
How to run a useful rent-vs-buy comparison
- Use the actual home price and rent for comparable properties.
- Enter realistic mortgage terms.
- Include ownership costs rather than comparing only payments.
- Choose a realistic time horizon.
- Make appreciation, rent growth and investment-return assumptions visible.
- Run cautious, middle and optimistic scenarios.
- Check whether the conclusion survives reasonable assumption changes.
If a small change in one assumption reverses the answer, the result is less decisive than a single headline number suggests.

Questions about renting vs buying
Is renting cheaper than buying?
Not universally. The result depends on property price, rent, mortgage terms, ownership costs, transaction costs, time horizon and assumptions about future prices and rent. Comparing the full financial position of both scenarios is more useful than comparing monthly payments alone.
Is rent wasted money?
Rent pays for the use of a home. Mortgage interest, property costs, maintenance and transaction costs are also costs of housing. Mortgage principal differs because it reduces debt and can build equity. A useful comparison accounts for all of these rather than labelling one payment wasted.
Does buying always become better if I stay long enough?
No universal break-even period exists. Staying longer can spread transaction costs and allow more principal repayment, but the result still depends on mortgage rates, home values, rent, maintenance and other assumptions.
Should mortgage principal count as a cost?
Principal repayment reduces the mortgage balance and therefore contributes to homeowner equity. It affects cash flow, but it is economically different from mortgage interest or maintenance expenses.
How does a down payment affect rent vs buy?
A larger down payment reduces the mortgage amount and usually reduces interest, but it also commits more cash to the property. Because this model includes opportunity cost, the alternative use of that cash also affects the comparison.
What is the rent-vs-buy break-even point?
In a financial model, the break-even point is where the calculated financial position of one scenario catches or overtakes the other. It depends on the assumptions entered and is not a guaranteed future date.
Does home appreciation make buying better?
Higher home-value growth generally improves the homeowner's projected equity, but future property prices are uncertain. Appreciation should be treated as an assumption and tested across multiple scenarios rather than as a guaranteed return.
How these examples were calculated
The examples on this page use the same calculation logic as the FinanceCalcWorks Rent vs Buy Calculator. Calculations use full precision internally and values shown here are rounded for readability.
The model accounts for mortgage amortisation, rent and rent growth, ownership costs, property-value assumptions, transaction costs and the alternative use of capital. Future rent, home prices and investment returns are assumptions, not forecasts.
