What the price-to-rent ratio shows
The price-to-rent ratio divides the price to buy a home by the annual rent for a comparable one. A $400,000 home that would rent for $2,200 a month ($26,400 a year) has a ratio of about 15. The ratio is a quick way to gauge whether housing in an area is expensive relative to what it earns in rent. A low ratio means homes are cheap compared with rents, which tends to favour buying; a high ratio means prices are steep relative to rents, which tends to favour renting and investing the difference. It is a housing-market temperature check in a single figure.
Reading the interpretation bands
A widely used rule of thumb splits the ratio into three bands. A ratio of 15 or below generally favours buying — prices are modest relative to rents, so ownership often costs less over time than renting. From 16 to 20 is a borderline zone where the decision depends heavily on your circumstances, how long you'll stay and local costs. A ratio of 21 or above tends to favour renting, because prices are high relative to rents and your money may work harder invested elsewhere. This calculator places your figure in the right band automatically.
What the ratio leaves out
The price-to-rent ratio is a starting point, not a verdict. It ignores mortgage rates, which hugely affect the true cost of buying; property taxes, insurance and maintenance, which owners pay and renters don't; transaction costs and how long you plan to stay; and expected price growth. Two cities with the same ratio can favour buying versus renting very differently once rates and taxes are layered in. Use the ratio to frame the question — is this a buy-friendly or rent-friendly market — then run a full rent-versus-buy comparison for your own numbers before deciding.
Using it as an investor
For investors, the price-to-rent ratio doubles as a valuation and yield signal: it is essentially the inverse of gross rental yield. A low ratio implies a higher yield and cheaper income, which is what buy-and-hold investors hunt for; a high ratio implies a low yield, more common in appreciation-driven markets. Read it alongside the gross rent multiplier and cap rate, which tell a similar story from different angles, and remember that a very low ratio can also flag a weaker area with higher risk. These tools use standard, published real-estate formulas and the figures you enter. They are estimates for planning and comparison, not financial, investment or tax advice — run your own numbers and speak to a qualified professional before you buy.
Frequently asked questions
How is the price-to-rent ratio calculated?
Price-to-rent ratio = home price ÷ annual rent. For a $400,000 home renting at $2,200/month ($26,400/year), the ratio is about 15. This calculator computes it and places it in a buy/rent band.
What price-to-rent ratio favours buying?
A common rule of thumb: 15 or below favours buying, 16–20 is borderline, and 21 or above favours renting. These are guides — mortgage rates, taxes and how long you'll stay all matter too.
Does the ratio account for mortgage rates?
No. It only compares price with rent, so it ignores interest rates, property taxes, maintenance and transaction costs. Use it as a first filter, then run a full rent-vs-buy analysis.
How does price-to-rent relate to rental yield?
It's essentially the inverse of gross rental yield. A low price-to-rent ratio means a high yield (cheap income), while a high ratio means a low yield, typical of appreciation-driven markets.
