Rent vs. Buy Calculator

The rent-versus-buy decision is one of the biggest financial choices most people make, and the right answer depends heavily on your circumstances — especially how long you plan to stay. Renting is often portrayed as 'throwing money away,' but buying carries large costs that renters avoid, so the honest comparison requires looking at the full picture over time, not just comparing rent to a mortgage payment.

Buying a home involves far more than the mortgage. Upfront, there's the down payment and closing costs. Ongoing, owners pay property taxes, homeowners insurance, maintenance (often estimated at around 1% of the home's value per year), and sometimes HOA fees — none of which build equity. Against these costs, owners gain two things renters don't: equity, as each payment reduces the loan balance, and appreciation, if the home rises in value. Over a long enough period, equity and appreciation can outweigh the carrying costs, tipping the math in favor of buying.

Renting is simpler and more flexible. A renter pays rent (which typically rises over time) plus renters insurance, with no maintenance, property tax or transaction costs, and the freedom to move easily. Crucially, a renter can invest the money a buyer ties up in a down payment and higher monthly costs, and those investments can grow — an opportunity cost that a fair comparison should consider.

The single most important variable is time horizon. Buying has high transaction costs (closing costs to buy, agent fees to sell), so it usually takes several years of ownership for appreciation and equity to overcome them. The widely cited 'five-year rule' suggests that if you'll stay fewer than about five years, renting often wins; stay longer, and buying tends to pull ahead. Local factors matter too: high-price, high-tax markets favor renting longer, while affordable markets with strong appreciation favor buying sooner.

There's also a lifestyle dimension money can't fully capture — stability, freedom to renovate, and pride of ownership versus flexibility and lower responsibility. This calculator focuses on the financial comparison, estimating the net cost of each path over your chosen time frame so you can fold the numbers into a decision that's ultimately about your life as much as your spreadsheet.
