Comparing rent with a mortgage payment alone is misleading. Buying carries property tax, insurance, maintenance, and the transaction costs of purchase and eventual sale, while only the principal portion of a payment builds equity. The honest comparison is total annual cost of owning, minus equity built, against annual rent.

Deciding whether to rent or buy a home is partly emotional, but the financial side can be modeled. The key question is not only which monthly payment is lower. A good rent vs buy comparison asks whether home equity, appreciation, and payment stability are strong enough to overcome closing costs, taxes, insurance, maintenance, and the opportunity cost of using cash for a down payment.
Buying is usually cheaper when you plan to stay long enough for equity and appreciation to offset the high upfront and ongoing costs of ownership. Renting is often cheaper when your timeline is short, local home prices are stretched compared with rent, or you can invest the down payment and monthly savings elsewhere.
The practical test is simple: compare the net cost of buying with the total cost of renting over the same number of years. If buying has the lower net cost, buying wins financially. If renting has the lower total cost, renting wins financially.
Total cost of renting equals the sum of rent payments over your time horizon, adjusted for expected rent increases.
Net cost of buying equals down payment, mortgage payments, taxes, insurance, and ownership costs minus home equity at the end of the period.
This is why two people with the same rent and mortgage payment can reach different decisions. A buyer staying 10 years in a rising market may build enough equity to win. A buyer moving after two years may not overcome closing costs and selling costs.
Use the calculator when you want to compare your exact home price, rent, mortgage rate, taxes, insurance, appreciation, rent increases, and time horizon.

It depends mostly on how long you stay. Buying carries large one-off costs at both ends, often 2% to 5% to purchase and around 5% to 7% to sell. Those have to be spread over your years in the property before ownership starts to win.
Principal and interest, property tax, insurance, any mortgage insurance, maintenance, and service or association charges. Maintenance is commonly estimated at roughly 1% of the property value a year and is the cost most often left out.
Only the principal portion of a payment is saving; the interest portion is a cost, like rent. Early in a mortgage most of the payment is interest, which is why buying and selling within a few years usually loses money.
The break-even period commonly falls somewhere around five years, but it varies widely with prices, rates and local rents. Calculate it for your own situation rather than trusting a rule of thumb.
A deposit sitting in a property is money not invested elsewhere. A fair comparison credits the renter with the return that deposit could have earned, otherwise the buying case is flattered.
No more than mortgage interest, property tax, insurance and maintenance do, none of which build equity either. Renting also buys flexibility and transfers the cost of major repairs to the landlord, which has real value.
The better choice depends on how long you will stay, what you would pay to rent, what you would pay to buy, and what return you could earn on cash not used for a down payment. For a fast answer, open the rent vs buy calculator and test the decision with your own assumptions.
