Rent vs. Buy Calculator

How to Use This Calculator

Enter your monthly rent, the home price you’re considering, your down payment percentage, and how long you plan to stay. The calculator handles the rest: mortgage math, property taxes, opportunity cost, and the break-even point where buying starts to win.

Move the sliders and watch the verdict update in real time. Use the “Show more options” toggle to fine-tune home appreciation, rent increases, and investment return assumptions.

The 5 to 7 Year Rule

A well-known rule of thumb: if you plan to stay fewer than 5 years, renting usually wins. Beyond 7 years, buying typically builds more wealth. The 5 to 7 year range is the toss-up zone where it really depends on your local market and what you’d do with the down payment money instead.

This calculator shows you your specific break-even point: not the rule of thumb, but the actual math for your numbers.

What Is the Break-Even Point?

The break-even point is the year when the total net cost of buying becomes less than the total cost of renting. Before that year, renting is cheaper. After it, buying pulls ahead.

It depends heavily on how much you put down, your mortgage rate, how fast the home appreciates, and what you’d earn if you invested the down payment in the stock market instead.

What Is Opportunity Cost?

Your down payment is a large chunk of cash, often $40,000 to $120,000. If you didn’t put it into a house, you could invest it in a low-cost index fund.

Opportunity cost is what that money could have earned in the market instead. This calculator factors that in, because most calculators don’t, and it makes a meaningful difference especially in the first 5 to 10 years.

Why Renting Isn’t “Throwing Money Away”

You’re paying for a place to live. Homeowners also “throw away” money: on mortgage interest (sometimes 70 to 80% of early payments), property taxes, insurance, and repairs. For the first several years, total housing costs often exceed comparable rent.

The real question isn’t whether renting wastes money. It’s when buying starts to make more financial sense. This calculator tells you exactly that.

What This Calculator Doesn’t Cover

This tool focuses on the financial math. It doesn’t weigh personal factors like job stability, desire to renovate, pets, schools, or the emotional value of owning your own place, all of which are real and valid reasons to buy even when the numbers slightly favor renting.

It also assumes a 30-year fixed mortgage and uses a flat 22% federal tax bracket for mortgage interest deductions. Your situation may differ.

Frequently Asked Questions

Is it better to rent or buy a home?

It depends on your timeline, local market, and what you’d do with your down payment if you didn’t buy. As a starting point, buying usually wins if you plan to stay for 7 or more years. Renting often wins for shorter timelines because the upfront costs of buying, including down payment, closing costs, and early mortgage interest, take years to recoup. This calculator shows your specific break-even point based on your actual numbers rather than a general rule.

How long do you need to stay in a home before buying makes financial sense?

For most people, the break-even point falls between 5 and 8 years, though it varies significantly based on your down payment size, mortgage rate, local home appreciation, and what your down payment would earn if invested instead. In high-appreciation markets, buying can make sense sooner. In flat or declining markets, the break-even can stretch past 10 years. Enter your numbers in this calculator to see your specific break-even year.

What is the opportunity cost of a down payment?

When you put $80,000 into a house as a down payment, that money stops being available to invest elsewhere. Opportunity cost is what that $80,000 could have earned in the stock market over the same period. At a 7% annual return, $80,000 grows to about $157,000 in 10 years. This calculator includes opportunity cost in its comparison, which most rent vs. buy tools skip. It’s one of the most important factors in the first 5 to 10 years after buying.

Why do people say renting is throwing money away?

This is a common oversimplification. When you rent, your payment covers housing. When you own, a significant portion of early mortgage payments also covers interest rather than equity, plus you pay property taxes, homeowner’s insurance, and maintenance on top. In the first few years of a mortgage, the “wasted” money in interest and fees can actually exceed what you’d spend in rent for a comparable home. Renting isn’t wasteful. It’s often the financially rational choice for shorter time horizons.

What is included in the total cost of owning a home?

The full cost of homeownership includes the mortgage payment (principal plus interest), property taxes, homeowner’s insurance, HOA fees if applicable, and maintenance costs. Many estimates put maintenance at roughly 1% of the home’s value per year, so a $400,000 home costs about $4,000 per year in average upkeep. This calculator includes property taxes and lets you model your own maintenance assumptions in the advanced settings.

Does home appreciation affect the rent vs. buy decision?

Yes, significantly. In a market where home prices rise 4 to 5% per year, buying builds equity faster and the break-even point comes sooner. In a flat or declining market, the break-even stretches further out and renting may win even over long timelines. This calculator uses a default 3% annual appreciation rate but lets you adjust it to match your local market.

Should I buy if I have a large down payment?

A larger down payment lowers your monthly mortgage payment and reduces the interest you pay over the life of the loan, which shortens your break-even point. But it also increases your opportunity cost, because a larger sum of money goes into an illiquid asset instead of the market. The relationship isn’t simple. This calculator lets you model different down payment percentages to see exactly how they shift your break-even year.

What mortgage rate should I use in the calculator?

Use the current rate you’ve been quoted by lenders, or check a current mortgage rate aggregator for today’s national averages. Even a 0.5% difference in mortgage rate can shift your break-even point by one to two years. Higher rates make renting more attractive relative to buying for longer. Lower rates accelerate the break-even.
