Housing

Price-to-income versus price-to-rent

Two ways to read housing value: affordability against incomes for buyers, and yield against rents for investors. What each ratio measures and when they disagree.

Two ratios are used to judge whether housing is expensive, and they answer different questions. The price-to-income ratio asks whether a household earning a typical income can afford a typical home. The price-to-rent ratio asks whether buying beats renting for the same property. This note explains both, how the OECD analytical series behind them is built, and why a market can look stretched on one measure and less stretched on the other.

Two reads on value

Price-to-income divides a house price by household income. A high reading means homes cost many years of income, which is the affordability question that matters to a buyer who intends to live in the property. Price-to-rent divides the same house price by the rent the property could earn. A high reading means the purchase price is large relative to the income it generates, which is the yield question that matters to an investor comparing housing with other assets.

Both are indices rather than currency amounts in the series Younivi republishes: each is set to 100 in 2015, so a value of 120 means the ratio has risen about a fifth since 2015. That convention makes countries comparable without pretending their currencies are. A ratio index is a comparison of two things within one economy, which is why it survives a currency translation that a raw price does not.

What the latest readings show

The two measures do not have to move together. Using the latest observations in the republished file, New Zealand's price-to-income index was 101.3 at December 2025 while its price-to-rent index was 121.4 — prices modestly above their 2015 relationship with incomes, but noticeably higher against rents. Spain sat well above 2015 on both, at 132.5 on price-to-income and 168.9 on price-to-rent in March 2026. Australia recorded 125.1 and 133.9, and the United States 125.1 and 133.2.

The pair is most informative when the two columns disagree. Canada at June 2026 shows a price-to-income index of 122.7 but a price-to-rent index of 119.5: expensive against incomes, less so against rents. Japan shows the reverse emphasis, with 114.1 on price-to-income but 139.8 on price-to-rent — a market that looks moderate against incomes and expensive against the income a property produces. Germany pairs 104.5 on price-to-income with 129.5 on price-to-rent, and the United Kingdom 104.5 with 110.1. No single ranking of "expensive" survives both columns.

How each ratio is derived

The two indices come from the same analytical house-price collection, and their denominators are what separate them. The income denominator is a flow accruing to households over a period; the rent denominator is a market price for housing services over the same kind of period. Both are then divided into a nominal house-price measure and rebased to 2015. Because the numerators share a source, much of the difference between the two series is about the denominator: incomes grow with the labour market over years, while rents respond to the housing market and can move faster in a shortage.

Younivi republishes both as levels with the source citation on each desk page. The desk does not compute them; the OECD compiles the underlying ratios, and the numbers should be read as that producer's construction, on that producer's schedule.

How to use them — and how not to

Used well, the ratios are stress gauges and comparisons: how far has this economy moved from a common reference, and does its housing look more stretched against income or against rent? Used badly, they become valuations. Neither says what a specific property is worth, and neither includes borrowing costs, which means a market can look expensive on both ratios while cheap finance keeps monthly payments manageable, or look moderate while high rates bite.

Three cautions follow. The ratios use averages, so they are blind to distribution: a market can be affordable for top earners and unaffordable for median ones. They are not forecasts, and a high reading has no built-in signal that prices will fall. And cross-country levels should be compared through the change since 2015 rather than as a league table, because tax rules, tenure patterns and rental regulation differ enough to shift what a given index value means.

Where this fits in the wider picture

Housing is simultaneously a consumption good and an asset, and the two ratios are the two sides of that duality. A household buying a home to live in is mostly asking the affordability question; an investor weighing a rental property is mostly asking the yield question. Public debate tends to blend the two, which is how the same market can be described as unaffordable and as a poor investment at the same time without contradiction.

Keeping the measures separate also clarifies what policy can and cannot do. Policies that raise incomes improve price-to-income without touching prices; policies that raise rents worsen price-to-rent without touching prices. Neither ratio is a target, and neither is a forecast. They are two lenses on the same object, and the honest reading is the one that says which lens is being used. Read side by side, they also show that a market can be expensive for one audience and reasonable for another, which is why a single verdict on "expensive" rarely settles an argument about housing.

How to read this on Younivi

The price-to-income page and the price-to-rent page on the House Price desk each show every licensed economy, ranked by its latest quarter, with the OECD citation. Companion notes cover the index base and the real series. Figures are republished official data, may lag the producer, and are not financial advice about any property decision.
