FAQ
How does this compare renting and buying?
It totals the cost of buying (down payment plus payments, minus the home’s value at the end) against the total rent paid over the same period, then shows which is cheaper.
What does it leave out?
It is a simplified estimate. It ignores property tax, insurance, maintenance, closing and selling costs, and the investment return you might earn on a down payment.
Why does home appreciation matter?
Appreciation builds equity that offsets the cost of buying. Higher assumed appreciation makes buying look better; higher rent increases make renting look worse.
Does the Rent vs Buy Calculator send my data to a server?
No. The Rent vs Buy Calculator runs entirely in your browser — your inputs never leave your device, and nothing is uploaded or stored.
Worked example
Renting at 20,000/month is 240,000/year. Buying adds an EMI plus maintenance and taxes but builds equity — the tool compares total cost over your expected stay; longer stays usually favour buying.
