How to Compare Renting and Buying With a Simple Worksheet

What a rent vs. buy worksheet does

A rent vs. buy worksheet is a side-by-side comparison of what you will actually spend each month and year under each option. It takes your local rent prices, your down payment amount, your mortgage rate, property taxes, insurance, maintenance costs, and other real numbers from your situation — not national averages — and shows you the total cost of each path. The worksheet does not tell you which choice is right for you. It tells you what each choice costs, so you can decide based on your own priorities.

The most useful worksheets separate one-time costs (down payment, closing costs, moving) from monthly costs (rent, mortgage payment, property tax, insurance, utilities, maintenance) and then add them up over a time period you choose — usually 5, 10, or 30 years. This matters because buying has high upfront costs but lower monthly costs over time, while renting has low upfront costs and higher monthly costs that rise with inflation.

Key Takeaways

• A worksheet shows your actual monthly and yearly costs for renting versus buying in your specific area, using real numbers from your situation.
• The most useful worksheets separate upfront costs (down payment, closing costs) from monthly costs (rent, mortgage, taxes, insurance, maintenance) and total them over 5, 10, or 30 years.
• You will need your local rent prices, your down payment amount, your expected mortgage rate, property tax rate for your county, homeowners insurance quotes, and an estimate of annual maintenance (usually 1 percent of home price).
• The worksheet reveals which option costs less over your time horizon, but does not account for personal factors like job stability, plans to move, or how much you value owning versus renting.

What numbers you need to gather

Before you open a worksheet, collect the actual figures for your area and situation. Start with rent: search rental listings in your target neighborhood for apartments or homes the size you want, and note the range. Do not use the lowest or highest price — use the middle. Check what utilities typically cost (your local utility company website usually shows average bills by season).

For buying, you need a down payment amount (what you can actually save, not what you wish you could save), a mortgage rate (call a lender or check current rates online — rates change weekly), and your property tax rate (your county assessor's office publishes this, usually as a percentage of home value). Get a homeowners insurance quote for a home in your price range in your county. Estimate annual maintenance at 1 percent of the home's purchase price — a $300,000 home costs roughly $3,000 per year in repairs and upkeep on average, though this varies widely by age and condition of the home.

You will also need closing costs if you buy (usually 2 to 5 percent of the loan amount, paid at signing), moving costs for either option, and property appreciation or depreciation assumptions if you want to project what the home might be worth when you sell. Many worksheets let you leave appreciation blank and just show the cost of ownership, which is fine — you can add appreciation separately if you want.

How to set up a basic worksheet

You can build a worksheet in a spreadsheet (Excel, Google Sheets) or use a template someone else has created. If you build your own, create two columns: one for renting, one for buying. Then create rows for each cost category.

For the renting column, list monthly rent, renters insurance (usually $10 to $20 per month), utilities, and any parking or pet fees. Multiply the monthly total by 12 to get the annual cost, then multiply by the number of years you plan to stay (5, 10, or 30). Add moving costs as a one-time expense at the start.

For the buying column, list down payment and closing costs as one-time expenses at the start. Then list monthly mortgage payment (a lender can calculate this for you based on loan amount, rate, and term), property tax (annual amount divided by 12), homeowners insurance (monthly), utilities, and annual maintenance. Multiply the monthly total by 12, then by the number of years. At the end, subtract what you owe on the mortgage (the remaining balance after your time horizon) to see your net cost — because you are building equity, not just spending money.

The bottom line of each column shows total cost over your time period. If renting is lower, renting costs less in pure dollars. If buying is lower, buying costs less — but only if you stay long enough to recoup your upfront costs.

Why the break-even point matters more than the total

The most important number on your worksheet is not the final total — it is the break-even point, the year when buying stops costing more than renting and starts saving you money. This is usually 5 to 10 years into ownership, depending on your down payment, mortgage rate, local property taxes, and how fast rent is rising in your area.

If you plan to stay in the home for less time than the break-even point, renting will cost you less in total dollars. If you plan to stay longer, buying will. This is why a worksheet is most useful when you already know roughly how long you will stay — if you are unsure, run the numbers for multiple time horizons (5 years, 10 years, 30 years) and see how the answer changes.

The break-even point also shifts if your assumptions change. If mortgage rates drop, buying becomes cheaper sooner. If rent rises faster than you expected, buying becomes cheaper sooner. If you need a larger down payment than you thought, buying becomes more expensive. A worksheet lets you test these "what if" scenarios by changing one number at a time and seeing how the answer shifts.

Common costs people forget to include

Renters often forget that rent usually rises each year when the lease renews — typically 3 to 5 percent per year, though this varies by market and by lease. A worksheet that assumes rent stays flat will underestimate the cost of renting over 10 or 30 years. If your worksheet has a line for "annual rent increase," use a realistic number for your area.

Buyers often underestimate maintenance and repairs. A new roof, a failed water heater, foundation cracks, or a broken HVAC system can cost thousands in a single year. The 1 percent rule (1 percent of home price per year) is a rough average — older homes often cost more, newer homes less. If you are buying an older home, increase this estimate.

Both renters and buyers forget about property tax increases (for buyers) and utility inflation (for both). If your worksheet lets you set an annual increase rate for these costs, use 2 to 3 percent per year as a conservative estimate. Some worksheets calculate this automatically; others require you to enter it manually.

What the worksheet does not tell you

A worksheet shows dollars, not life. It does not account for the fact that you cannot move a house if you get a job offer in another city, or that a landlord can raise your rent 30 percent when your lease ends, or that you might lose your job and need the flexibility to move quickly. It does not measure the satisfaction of owning your own space, or the stress of a mortgage payment, or the freedom of renting without responsibility for repairs.

A worksheet also assumes you will stay in the home (or apartment) for the full time period you entered. If you buy and sell after 3 years, you will pay realtor fees (usually 5 to 6 percent of the sale price) and closing costs again, which can wipe out any equity you built. A worksheet can show you this if you change the time horizon to 3 years, but it does not predict whether you will actually stay or need to move.

Finally, a worksheet does not account for your personal financial situation. If you have unstable income, a large emergency fund matters more than a lower monthly cost. If you have high-interest debt, paying that off might be more important than buying a home. If you are saving for other goals (education, starting a business, travel), the money tied up in a down payment might have a higher value to you elsewhere.

Where to find a ready-made worksheet

The New York Times has a rent vs. buy calculator that lets you enter your numbers and see the break-even point. The Consumer Financial Protection Bureau (CFPB) publishes a worksheet template you can download and fill in yourself. Zillow and Trulia both have online calculators that use their own rent and home price data for your area, though you should verify the numbers with local listings before trusting them.

If you work with a mortgage lender or real estate agent, they often have worksheets they use with clients — ask to see one. Keep in mind that a lender's worksheet may be designed to show buying in the best light, and a real estate agent's worksheet may do the same. The most useful worksheet is one you build yourself or one from a neutral source like the CFPB, because you control every number and can see exactly what assumptions are built in.

Frequently Asked Questions

Should I include home appreciation in my worksheet?

Only if you want to. Home appreciation is unpredictable and varies widely by location and time period. A worksheet that shows only the cost of ownership (what you spend) is clearer than one that tries to predict what your home will be worth. You can always add appreciation separately as a "what if" scenario after you see the base numbers.

What if I do not know my mortgage rate yet?

Use the current average rate for your area and loan type (30-year fixed, 15-year fixed, adjustable-rate). Rates change weekly, so check a lender's website or Freddie Mac's weekly survey. Run the worksheet at two or three different rates (one higher, one lower) to see how sensitive your break-even point is to rate changes.

Can a worksheet tell me whether to rent or buy?

No. A worksheet tells you which option costs less in dollars over a specific time period. Whether that matters depends on your job stability, your plans to move, your comfort with debt, and what you value. If the worksheet shows buying costs $50,000 less over 10 years but you might get a job offer in another city in 3 years, renting might still be the better choice for you.

How do I account for rent increases in my worksheet?

Most spreadsheet-based worksheets let you enter an annual rent increase percentage (usually 3 to 5 percent). Some online calculators do this automatically. If your worksheet does not have this feature, you can calculate it manually: multiply your monthly rent by 12, then increase it by your expected percentage each year before adding it to the total.

What if my down payment is smaller than I want?

Run the worksheet twice — once with your actual down payment, and once with a larger down payment. You will see how much the break-even point shifts. This shows you whether saving an extra $20,000 or $50,000 for a down payment is worth delaying your purchase, or whether buying sooner with a smaller down payment (and paying mortgage insurance) makes more sense for your situation.
