Price to Income Ratio Calculator

What the price to income ratio measures

The price to income ratio is one division: the price of a home divided by the gross annual income of the household buying it. Planners use medians, so the national version divides the median home price by the median household income. That version is called the median multiple, and it is the number behind most housing affordability headlines.

The arithmetic takes one line. The median existing home in the United States sold for $417,500 in September 2026, and median household income was $83,730 in 2024, so the national ratio is 417,500 / 83,730 = 4.99, about five years of income for the median house. A buyer earning exactly the median who pays exactly the median price is handing over five full years of pay before tax for the house.

Run your own two numbers through the calculator above and the same division happens instantly, with the band and the payment math added underneath. The ratio is a screening tool, not a decision, and the sections below show what it misses.

The Demographia bands: what counts as affordable

The rating scale most housing reports use comes from the Demographia International Housing Affordability report, which has rated major markets every year since 2005. The 2026 edition divides the bands into five tiers, and the thresholds are worth memorizing because reporters quote them without explaining.

The United States as a whole scored 4.5 in the 2024 data, which means the median house cost four and a half years of median income. That is down from 4.8 in 2023 but up from 3.9 in 2019, so the country lost more than half a year of affordability during the pandemic run up and has clawed back only a slice of it. The historic norm in the report's early editions was at or under 3.0, and markets that still hit that line today are rare enough to make the news.

The bands matter because they strip out interest rates, down payments and taxes and leave one blunt question: how many years of work does this house cost? A market can move from affordable to severely unaffordable without a single dollar of construction happening, when incomes stall and prices drift up.

Worked example: two buyers, two markets

Buyer A is shopping in a mid priced market: a $340,000 house on a $95,000 household income. The ratio is 340,000 / 95,000 = 3.58, which lands in the moderately unaffordable band. Now check the payment behind that number. Twenty percent down leaves a $272,000 loan, and at 6.5 percent over 30 years the principal and interest is $1,719.23 a month. Property tax and insurance at about 1.2 percent of the price adds $340.00, for total housing of $2,059.23. Monthly gross income is 95,000 / 12 = 7,916.67, so housing eats 26.0 percent of gross pay, which most lenders treat as comfortable.

Buyer B finds a $250,000 house on a $100,000 income. The ratio is 2.50, inside the affordable band, and the payment math confirms it: the same 20 percent down and 6.5 percent rate puts housing near 18 percent of gross income, with room to absorb a rate rise or a job gap.

The two numbers answer different questions and both are useful. The ratio says how a market prices itself against its own paychecks, which is what makes cities comparable. The payment share says whether one specific household can carry one specific house. A ratio of 3.58 reads as a yellow flag in the headlines, yet for Buyer A the actual monthly budget is fine; the band describes the market, not the buyer.

Why the ratio ignores your mortgage rate

The ratio divides price by income and stops there, so two identical ratios can carry sharply different monthly bills depending on when they were measured. Interest rates decide that bill, and the difference is not subtle. Take the median home at $417,500 with 20 percent down, a $334,000 loan over 30 years, and watch the payment move with the rate alone.

A point and a half of rate adds $333 a month, which is $11,988 over the first three years, without the house changing by a dollar. Against median gross monthly income of 83,730 / 12 = 6,977.50, the 6.5 percent total of $2,528.61 is a 36.2 percent payment share. The ratio read 5.0 and said seriously unaffordable; the payment share says the same thing with more precision, because the household is left with under $4,450 a month for everything else.

This is also why the same ratio meant less in 2019, when rates sat near 4 percent, than it does at 2026 rates. For the new construction side of the market, the Census Bureau put the median sales price of new houses at $410,700 in the second quarter of 2026, per the series it publishes with HUD (FRED, MSPUS series), and the same payment logic applies.

How to use the ratio when you shop

Flip the formula and the ratio becomes a price ceiling you can write on a notepad. Multiply your gross annual household income by 3.0 and you have the price of a home that scores affordable by the Demographia line. Median income of $83,730 clears 3 x 83,730 = 251,190, so an affordable median house costs about $251,000 today. Run the same multiplication on your own pay: $95,000 supports $285,000, and $140,000 supports $420,000.

The reverse direction is just as handy. Divide the price you are eyeing by 3.0 and you get the income the affordable line demands: a $417,500 house needs 417,500 / 3 = 139,167. If your income sits below that, the choice is a smaller house, a bigger down payment, a longer commute or a stretch on the payment share, and the ratio has told you which lever is doing the work.

Keep two companions next to it. The 28 percent rule caps housing at 28 percent of gross monthly income, which is a payment test the ratio cannot run; the mortgage calculator handles it. And a full affordability check folds in debts, taxes and closing costs, which the how much house can I afford calculator stacks up line by line. Use the ratio to pick the market and the price band, then use the payment tools to pick the actual house.

What the numbers say right now

Three sources anchor the 2026 picture. The National Association of Realtors reported the median existing home price at $417,500 in September 2026, up 1.3 percent from $412,300 a year earlier and the 39th straight month of year over year gains (NAR newsroom). The Census Bureau reported median household income of $83,730 for 2024 (Census, Income in the United States: 2024). And Demographia scored the national median multiple at 4.5 on 2024 data (Demographia 2026 edition). Divide the first two and you get 4.99, which sits at the top of the seriously unaffordable band; Demographia's own 4.5 uses metro level medians and a slightly older price vintage.

Regional medians from the same NAR release show how wide the spread is under the national number.

The Midwest sits at 3.9, a hair inside the moderately unaffordable band and close enough to 3.0 that a modest income premium buys affordability. The West at 7.3 is deep into severe territory. Same country, same month, and the difference between the two regions is roughly 2.9 million dollars of house for the same national median paycheck.

Where the ratio misleads

The ratio is a screening number, and four blind spots cause most of the bad conclusions drawn from it.

• Medians vs your market. A national or metro median says nothing about the street you are bidding on. A condo two blocks away can carry a ratio of 2.5 against the same metro that averages 6.0.
• Gross vs net. The standard ratio divides by gross income. Your budget lives on net pay, and after taxes, health premiums and retirement withholding, net is often 25 percent smaller. A ratio of 4.5 on gross can be 6.0 on what lands in the account.
• It is blind to rates and debts. As the table above showed, rate moves alone shift the payment by hundreds of dollars. Student loans and car payments do the same on the other side, and neither appears in the ratio.
• Income data lag. The freshest official income figure is 2024, while prices quote the current month, so a ratio built from published figures mixes vintages. That is worth a point or two of drift in fast moving markets.

The honest workflow is to let the ratio rank markets, then replace every median with your real numbers before deciding. Price from the listing, income from your pay stub, rate from a same day quote, taxes from the county assessor. The ratio gets you to the right city and the right price band; the payment math on your own figures closes the deal.
