Rent vs Buy Calculator

Getting started is pretty straightforward. You'll enter a few key numbers about your current situation or the scenario you're considering, and the calculator will generate a side-by-side comparison.

• Monthly rent: What you currently pay, or what you'd expect to pay for a comparable rental.
• Home purchase price: The price of the home you're thinking about buying.
• Down payment: The amount you plan to put down upfront, either as a dollar figure or a percentage.
• Mortgage interest rate: Use your best estimate based on current rates or a quote from a lender.
• Loan term: Most people choose a 30-year mortgage, but 15-year is also common.
• Annual home appreciation rate: How much you expect the home's value to increase per year.
• Investment return rate: If you were renting, what return might you earn by investing the down payment instead?
• How long you plan to stay: This one matters a lot. The longer you stay, the more buying tends to make sense.

Once you fill in those fields, the calculator will estimate your total costs for both renting and buying over the time period you choose. It'll also show your break-even point, which is when buying officially becomes the cheaper option.

This question has been argued at dinner tables and in financial advice columns for decades, and there's a reason it keeps coming up: it genuinely depends.

Buying a home builds equity over time. Every mortgage payment you make puts a little more ownership in your pocket rather than your landlord's. If home values rise, that equity grows even faster. There's also a stability factor that renting simply can't match. You're not subject to a landlord raising your rent or deciding not to renew your lease.

But renting has real advantages too. You're not on the hook for a busted water heater or a roof that needs replacing. You have flexibility to move without the friction of selling a property. And if you're in an expensive housing market, renting might free up cash that you can put to work in other investments.

A few questions worth asking yourself before deciding:

• How long do I plan to stay in this area? (Less than two or three years usually favors renting.)
• Do I have enough saved for a down payment and closing costs without draining my emergency fund?
• Is my income stable enough to handle a mortgage plus unexpected home repairs?
• How does the local housing market look? Are home prices already stretched, or is there room for appreciation?

Neither choice is inherently smarter. The right answer is the one that fits your finances, your timeline, and your life right now.

At first glance, comparing monthly rent to a mortgage payment seems simple. But the real comparison is a lot more layered than that.

When you rent, your monthly cost is pretty much what it is. Rent, maybe renters insurance, and utilities. Simple.

When you buy, your monthly outlay includes more moving parts:

• Principal and interest: The core of your mortgage payment.
• Property taxes: Varies widely by location, but typically 1 to 2 percent of the home's value per year.
• Homeowner's insurance: Usually a few hundred dollars a month depending on your home and location.
• Private mortgage insurance (PMI): Required if your down payment is under 20 percent.
• HOA fees: If you're buying a condo or home in a managed community, these can add hundreds per month.
• Maintenance and repairs: The general rule of thumb is to budget 1 percent of your home's value per year.

It's common for buyers to underestimate those last three categories, which is why their monthly budget gets tighter than expected after closing. A fair comparison accounts for all of these costs, not just principal and interest versus rent.

Your mortgage is the biggest lever in the buy scenario, so it's worth understanding how the numbers actually work.

The down payment is what you pay upfront. A conventional loan typically requires anywhere from 3 to 20 percent down. A higher down payment means a smaller loan, a lower monthly payment, and you avoid PMI. But it also means a lot more cash tied up in a single asset on day one.

The interest rate has an enormous effect on total cost. Even a half-point difference in your rate can add or subtract tens of thousands of dollars over the life of a 30-year loan. That's not an exaggeration. On a $400,000 loan, the difference between a 6.5% and a 7% rate works out to roughly $130 more per month and over $46,000 more in total interest paid.

Here's a simplified look at how different down payments affect a $400,000 home purchase at a 7% rate over 30 years:

Keep in mind these figures are principal and interest only. Add taxes, insurance, and maintenance and your real monthly cost climbs from there. The calculator above factors all of this in so you're comparing apples to apples.

Nobody loves talking about this part, but ignoring it leads to real financial stress. Owning a home comes with costs that renters simply don't deal with.

Closing costs are the first surprise. When you buy, you'll typically pay 2 to 5 percent of the purchase price in closing costs before you even get the keys. On a $350,000 home, that's $7,000 to $17,500 out of pocket, on top of your down payment.

Maintenance is ongoing and unpredictable. The 1 percent annual rule is a decent estimate on average, but some years you'll spend nothing significant and other years the HVAC dies, the roof needs patching, and a pipe bursts in the same month. You need a reserve fund for this.

Other costs that tend to sneak up on homeowners:

• Landscaping and lawn care if you don't want to do it yourself.
• Pest control, particularly in warmer climates.
• Appliance replacement over time. Dishwashers, refrigerators, water heaters all eventually give out.
• HOA fees and special assessments, which can increase without much warning.
• Selling costs when you eventually move. Real estate agent commissions alone often run 5 to 6 percent of the sale price.

These costs don't make buying a bad choice, but they do need to be part of your math. A rent vs buy comparison that ignores them is going to paint an unrealistically rosy picture of homeownership.

Two variables that often get overlooked in rent vs buy comparisons are how much rent will increase over time and what happens to the money you don't tie up in a down payment.

Rent isn't fixed. Historically, rents in the U.S. have increased at roughly 3 to 5 percent per year on average, though that varies a lot by market. When you lock in a fixed-rate mortgage, your principal and interest payment stays exactly the same for 30 years. That's a real advantage. As rents climb around you, your housing cost stays predictable. Over 20 or 30 years, that stability adds up to significant savings compared to renting.

On the flip side, if you rent instead of buy, you're not tying up $60,000 or $80,000 in a down payment. If you invest that money instead, it could grow meaningfully over time. A common assumption is a 6 to 8 percent average annual return in a diversified stock portfolio, though of course returns vary and there's no guarantee.

This creates an interesting tradeoff. Buying builds equity in an appreciating asset. Renting keeps your capital liquid and potentially growing in other investments. Which path comes out ahead depends on local home appreciation, your actual investment behavior, how long you stay, and market conditions during your specific window of time.

The honest answer is that both paths can build wealth. The calculator models both scenarios so you can see how different assumptions about rent inflation and investment returns affect the comparison over your chosen time horizon.

The break-even point is the moment when the total cost of buying a home drops below what you would have spent renting over the same period. Before that point, renting is often cheaper. After it, buying tends to win.

Why does it take time for buying to break even? Because the upfront costs of purchasing are steep. Closing costs, down payment opportunity cost, and the early years of a mortgage where you're paying mostly interest rather than building equity all work against you initially.

The break-even timeline varies a lot depending on:

• How high your closing costs were
• How fast home values are appreciating in your area
• How much rent would have increased if you'd stayed a renter
• Your mortgage rate and down payment size
• Whether you're investing the difference if you rent

In many markets, the break-even point falls somewhere between 4 and 7 years. In expensive cities with slow appreciation, it can stretch to 10 years or longer. In more affordable markets with strong appreciation, it might come in under 3 years.

This is why the question "how long do you plan to stay?" matters so much. If you're likely to move in two years, buying almost never makes financial sense. If you're putting down roots for a decade or more, the math usually swings toward buying, sometimes substantially.

Beyond the numbers in the calculator, a handful of real-world factors shape which choice makes sense for you specifically.

Your local housing market is huge. In some cities, home prices are so elevated relative to rents that buying just doesn't pencil out for most people. In other markets, buying is clearly the smarter financial move because prices are reasonable and rents are high. There's no universal answer.

Job stability and income flexibility matter a lot. A mortgage is a long-term commitment. If your income fluctuates or your industry is unpredictable, carrying a mortgage adds financial risk that renting doesn't.

Life stage and personal plans factor in too. Are you single and likely to move for work or relationships? Renting gives you freedom. Do you have a growing family and want to stay put? Buying starts to make a lot more sense.

Credit score and financing access affect what mortgage rate you qualify for, which in turn affects how competitive buying is against renting.

A few more things worth weighing:

• Tax considerations: The mortgage interest deduction exists, but with standard deductions being higher now, it benefits fewer buyers than it used to.
• Emotional value: Stability, the ability to renovate, having a space that's truly yours. These are real, even if they don't show up in a spreadsheet.
• Rental market tightness: In areas where rental inventory is low and landlords raise rents aggressively, buying starts to look a lot more attractive.

Run the numbers, but also be honest with yourself about where you are in life. The best financial decision is one you can actually stick with and that fits how you actually live.
