Rent vs Buy Calculator
Not rent against instalment — net worth against net worth. The buyer builds equity and pays interest and upkeep; the renter invests the down payment and the monthly difference. See who is ahead, and when.

Buying usually loses over a short stay and wins over a long one, because the costs of getting in and out are paid once but the equity keeps building. Where your own crossover falls is the whole question.
Step by step
How the comparison is built
The buyer's side
Down payment and buying costs up front, then instalments and upkeep. At the end: property value less selling costs, less the loan still outstanding.
The renter's side
The same money that would have gone into the down payment and buying costs is invested, and so is any monthly difference.
Rent rises, instalments do not
Rent is grown each year; a fixed-rate instalment stays put, which is where the buyer gains over time.
Compare at your horizon
The answer depends more on how long you stay than on any other input.
Reading the result
The renter has to actually invest the difference
The comparison assumes the renter puts the money they did not spend on a down payment, and the gap between rent and instalment, into something that earns a return. That assumption carries the entire renting side of the model.
A renter who spends the difference ends up with neither the property nor the savings. In that case buying wins easily, and no calculator is needed to see it.
Transaction costs are why short horizons favour renting
Buying carries substantial one-off costs — stamp duty, registration, advance tax, agent commission — and selling carries more. Those are sunk at both ends, so a purchase held only a few years has to appreciate meaningfully just to break even against renting.
Appreciation is an assumption, not a fact
The result is highly sensitive to the growth rate you enter, and property in Pakistan has had long flat periods as well as sharp runs. Run the comparison with a conservative figure as well as an optimistic one; if the answer flips between them, the honest conclusion is that it is close.
Where this stops
This models money. It does not price security of tenure, the freedom to modify a home you own, or the flexibility to move at short notice — and for most households at least one of those matters more than the arithmetic.
FAQs
Rent vs buy FAQs
Why compare net worth instead of monthly cost?
Because comparing an instalment with a rent is not a comparison at all — part of an instalment buys you equity, and all of a rent is gone. The only fair question is what each path leaves you owning at the end of the period you actually stay. That is what this page computes: the buyer's equity after selling costs, against the renter's investment portfolio.
What is the renter assumed to do with the money?
Invest it, consistently. The down payment and the buying costs go in at the start, and in any month where the buyer's outgoings exceed the rent, the difference goes in too. A renter who spends that difference instead ends up worse off than this calculator shows — the discipline is doing the work, not the renting.
Why do transaction costs matter so much?
Because they are paid on the way in and again on the way out, and they do not come back. Stamp duty, registration, agent commission and the advance tax on the transfer make a short stay expensive: buy and sell within a couple of years and those costs can swallow whatever appreciation you earned. Length of stay is usually the single biggest factor in this decision.
Is property appreciation a safe assumption?
No, and it is the input people are most confident about and most wrong about. Pakistani property has had long flat stretches and sharp runs, and averages hide both. Try the calculation with a low appreciation figure as well as a hopeful one — if the answer flips, you have learned the real answer, which is that the decision rests on a forecast nobody can make.
What about rent inflation?
It matters as much as appreciation and is often overlooked. A tenancy is repriced regularly, so renting gets more expensive over time while a fixed-rate instalment does not. That is a genuine advantage of buying, and it is why the rent growth rate is a separate input here.
Are taxes included?
Ownership costs are entered as a yearly percentage of value, which is where property tax, insurance and maintenance belong. Purchase and sale taxes belong in the buying and selling cost percentages — advance tax on the purchase, on the sale, stamp duty and registration are all real and all substantial. The site has separate calculators for each of those if you want exact figures rather than a percentage.
Does it account for the security of owning?
No calculator can. Not being asked to vacate, being able to alter the place, and what a home means to a family are real and are not in these numbers. Treat the output as one input to the decision, not the decision.
What if I would not invest the difference anyway?
Then be honest and set the investment return low or to zero, and see what happens. For many people the forced saving of an instalment is precisely the point — a mediocre asset you actually pay into beats a better one you never fund.
