How to use
- 01
Enter what you paid for the house, the closing costs you paid when you bought, and what it sold for or would sell for today.
- 02
Enter the years you owned it and the average yearly inflation over those years. CPI-U averaged 3.35% a year from August 2016 to August 2026; the CPI Inflation Calculator gives the figure for your own dates.
- 03
Enter the total spent on improvements, such as a new roof or a remodel, and your yearly maintenance as a percentage of the home's value.
- 04
Enter the average yearly property tax and insurance, and the selling costs as a percentage of the sale price.
- 05
Read the real return after every cost, then the price appreciation before and after inflation, the break-even sale price and the year-by-year table.
Formula
Price appreciation a year = (sale price ÷ purchase price)^(1 ÷ years) − 1. After inflation = ((sale price ÷ purchase price) ÷ (1 + inflation)^years)^(1 ÷ years) − 1. The estimated value moves from the purchase price to the sale price at the appreciation rate; each year's maintenance = the value at the start of that year × the maintenance percentage. Money paid in = purchase price + closing costs at the start, then maintenance + property tax + insurance + (improvements ÷ years) each year. Net proceeds = sale price × (1 − selling costs %). The real return is the yearly rate at which the purchase outlay equals the present value of every later cash flow restated in purchase-year dollars (each divided by (1 + inflation)^year). Break-even sale price = (every payment grown by inflation to the sale year) ÷ (1 − selling costs %).
Example
A house bought for $300,000 with $6,000 of closing costs sells for $480,000 after 10 years, while inflation averaged 3.35% a year. The price rose 4.81% a year, or 1.41% after inflation. Over the decade the owner spent $25,000 on improvements, $37,405 on maintenance at 1% of the home's value, rising from $3,000 in year 1 to $4,580 in year 10, and $4,500 a year of property tax and $1,800 a year of insurance: $100,405 of carrying costs in all. Selling costs at 6% take $28,800. Counting everything, the house returned 0.54% a year before inflation and −2.72% a year after it, leaving the owner $119,777 behind in today's dollars. The purchase price alone is $417,086 in today's dollars, and the sale price needed to break even in real terms is $607,422. With no selling costs at all, the real return would still be −2.01%.
Definitions
- Nominal appreciation
- The yearly rate at which a home's price rose in dollars, from purchase price to sale price, before inflation or costs.
- Real appreciation
- The yearly rise in a home's price after removing inflation over the same years.
- Carrying costs
- The recurring costs of owning a home: maintenance and repairs, property tax and insurance.
- Unlevered return
- The return on a property as if it had been bought entirely with cash, leaving out the effect of a mortgage.
- Break-even sale price
- The sale price at which the proceeds after selling costs return everything paid in, restated for inflation, so the real return is zero.
Good to know
Price appreciation is not the return on a house
When people say a house was a good investment, they usually mean its price went up. That number is real, but it is not the return. A house bought for $300,000 and sold for $480,000 ten years later, this page's example, rose 60% in price, or 4.81% a year compounded. Two things stand between that figure and what the owner actually earned. The first is inflation. Over the same years prices in general rose too: CPI-U went from 240.849 in August 2016 to 334.980 in August 2026, according to the Bureau of Labor Statistics, a rise of 39.08%, or 3.35% a year. In today's dollars the $300,000 purchase price is $417,086, so a sale at $480,000 is a much smaller real gain than it looks. Dividing properly, real appreciation is 1.41% a year. The second is the cost of owning. A portfolio of funds can be held for little beyond small fees; a house demands closing costs to buy, property tax and insurance every year, maintenance and repairs, occasional improvements and selling costs at the end. In the example those come to $6,000 to buy, $25,000 of improvements, $100,405 of maintenance, property tax and insurance, and $28,800 to sell. Counting every one of those cash flows, the house returned 0.54% a year in nominal terms and −2.72% a year after inflation. The owner is $119,777 behind in today's dollars compared with money that merely kept its buying power. That does not make the purchase a mistake; the third section explains what the figure leaves out. It does mean the price chart and the return are different things, and that a house needs real appreciation just to stand still once its costs are counted. On these figures, the break-even sale price in real terms is $607,422, about 27% above the actual sale.
The costs a price chart leaves out
Each cost of owning works on the return differently, and it helps to know which ones dominate. Carrying costs are usually the largest because they recur every year. In the example, property tax of $4,500 and insurance of $1,800 a year come to $63,000 over ten years, and maintenance at 1% of the home's value adds $37,405, rising from $3,000 in the first year to $4,580 in the last as the value climbs. Together, $100,405 is a third of the purchase price. Property tax and insurance vary widely from place to place and change over time, so enter averages over your years of ownership rather than this year's bill alone. Maintenance is the hardest to know; 1% of value is a placeholder, and the Home Maintenance Budget Calculator builds a figure from the home itself. Improvements are the second group: a new roof, an addition, a remodeled kitchen. They help the sale price, which the sale price field already captures, but they are also money in, so they belong on the cost side. The example spreads $25,000 evenly across the ten years, and the Renovation ROI Calculator estimates how much of a given project tends to come back. Transaction costs come first and last: closing costs at purchase and selling costs at sale. Each is paid once, but they are large, and over a short ownership they can swamp the appreciation. At 6% of a $480,000 sale, selling costs are $28,800; removing them entirely would lift the example's real return only from −2.72% to −2.01%, which shows how much the recurring costs matter. Commissions, seller-paid closing costs, concessions and transfer taxes all count, and the Home Sale Proceeds Calculator itemizes them. Put together, the example's carrying costs and improvements equal 42% of the purchase price over a decade, which is why the real return after costs falls so far below the real appreciation.
Rent saved, the mortgage, and what this return leaves out
This page answers a narrow question on purpose: how did the house do as an investment, as if it had been bought with cash? Two large things sit outside that question, and either can change the verdict on buying. The first is the rent you did not pay. An owner who lives in the house gets the use of it every month, and that housing has a market value, roughly what it would cost to rent the same home. That is a return from owning just as surely as price appreciation, and over a decade it adds up to a large sum. A house whose price lags inflation once costs count can still have been a better deal than renting, because the owner avoided rent the whole time. Whether it was is a different calculation, which the Rent vs Buy Calculator makes by setting the full cost of owning against the full cost of renting. The second is the mortgage. Most homes are bought with a loan, which changes the return on the owner's own money even though it does not change the house's price. With a 20% down payment, a 10% rise in the home's price is a 50% gain on the cash put in, before interest and costs, and a 10% fall is a 50% loss. Borrowing adds interest as a cost but lets a smaller amount of cash capture the whole house's appreciation. That leverage can turn a modest real price gain into a strong return on equity, or a price fall into a painful loss. This page leaves leverage out so that the house itself can be judged. Taxes are outside the figures too. Gain on a main home is often tax-free: after owning and living in it for two of the last five years, an owner can exclude up to $250,000 of gain, or $500,000 on a joint return, according to IRS Topic 701. The Home Sale Capital Gains Calculator applies the rules. Read the real return here as one input among several, not as a verdict on buying.
Getting the inputs right for your own house
The result is only as good as the figures entered, and a few are easy to get wrong. Start with inflation. Use the average yearly change in the Consumer Price Index over the years you owned the home, not this year's figure. For the ten years to August 2026 it was 3.35% a year compounded, from the Bureau of Labor Statistics' CPI-U index levels of 240.849 and 334.980. For other dates, the CPI Inflation Calculator gives the total change between two years; the yearly average is one plus that change, raised to the power of one divided by the years, minus one. Enter the sale price you actually received, or a realistic estimate of what the home would sell for now, not a hopeful listing price. For purchase costs, use the closing costs on your settlement statement. For improvements, add up the larger projects over the years; receipts, permits and contractor invoices are the best guide. Keep ordinary repairs out of that figure and in maintenance, so nothing is counted twice. Property tax and insurance should be averages over your ownership, since both change over time. If you have the old bills, average them; if not, a figure between the first and last years is a reasonable estimate. Maintenance is the least certain input, which is why it is a percentage you can vary. Try the page at a lower and a higher rate and see whether the conclusion changes. For selling costs, include commissions, seller-paid closing costs or concessions, and transfer taxes, as a share of the sale price; the example's 6% is an assumption, not a benchmark. Finally, mind the years. A short ownership squeezes the buying and selling costs into few years and drags the yearly return down hard, while a long one spreads them thin. Running the same house at five and fifteen years shows how much the holding period alone matters.
Frequently asked questions
Did my house beat inflation?
Compare the price gain with inflation first, then count what owning cost. On this page's example, a house bought for $300,000 and sold for $480,000 ten years later rose 4.81% a year, or 1.41% a year after 3.35% inflation. Once $6,000 of closing costs, $25,000 of improvements, $100,405 of maintenance, property tax and insurance, and $28,800 of selling costs count, it returned −2.72% a year after inflation. It would have had to sell for $607,422 to break even in real terms.
Why does this leave out the rent I saved?
Because it measures the house as an investment, and rent saved is a return from living in it. That return is real, which is why a house that loses to inflation on this page can still have been a better choice than renting. The Rent vs Buy Calculator weighs both sides.
What about my mortgage?
This page treats the house as if it had been bought with cash. A mortgage adds interest to the costs but lets a smaller down payment control the whole house, which magnifies the return on your own money in both directions. The price appreciation here does not change with a loan; the return on your cash does.
What counts as an improvement rather than maintenance?
Improvements add to the home or extend its life, such as a new roof, an addition or a remodeled kitchen. Maintenance and repairs keep it in working order. Improvements go in as one total and are spread evenly across the years; maintenance is a yearly percentage of the home's value. Keep the two apart so nothing is counted twice.
What inflation rate should I use?
The average yearly change in the Consumer Price Index over the years you owned the house. CPI-U went from 240.849 in August 2016 to 334.980 in August 2026 (BLS), 39.08% in total, or 3.35% a year compounded. For other dates, the CPI Inflation Calculator gives the change between any two years.
How is the break-even sale price figured?
It is the sale price that, after selling costs, returns everything you paid in, with each payment grown by inflation to the year of sale. In the example the purchase price alone is $417,086 in today's dollars. Adding the closing costs, improvements, maintenance, tax and insurance restated the same way, and covering 6% selling costs, gives $607,422.
Do I owe tax on the gain?
Often not. After owning and living in the home for two of the last five years, you can exclude up to $250,000 of gain, or $500,000 on a joint return (IRS Topic 701). This page is before tax; the Home Sale Capital Gains Calculator checks the rules for your sale.
