What Is Owners' Equivalent Rent (OER)?
Let me explain Owners' Equivalent Rent, or OER, directly to you. It's the amount of rent you'd need to pay to replace your owned house with a rental property. We also call this the rental equivalent. Essentially, OER calculates the monthly rent that matches the expenses of owning a property, such as your mortgage, taxes, and similar costs.
Key Takeaways
- Owners’ equivalent rent (OER) measures how much money a property owner would have to pay in rent to be equivalent to their cost of ownership.
- OER is used to measure the value of real estate markets, where it can help direct individuals to either buy or rent based on the total monthly cost.
- OER tends to be linked to inflation; as inflation rises, so does OER.
Understanding Owners' Equivalent Rent
As a homeowner, you should know that Owners’ Equivalent Rent is a statistic we follow closely, and it's tracked by the Bureau of Labor Statistics. They gather the data through surveys where they ask household members—referred to as consumer units—this question: 'If someone were to rent your home today, how much do you think it would rent for monthly, unfurnished, and without utilities?'
OER serves as a common measure to gauge shifts in real estate market values. If OER is high, buying a home might make more sense than renting. Conversely, if it's low, renting could be the smarter choice.
You'll notice that Owners’ Equivalent Rent usually moves in line with the Consumer Price Index. It increases over time, and it was rising steadily until 2022, when high inflation hit the economy, causing OER to spike at faster rates than before.
Evaluating OER
When we look at housing and shelter in economic terms, Owners' Equivalent Rent of a primary residence is one of three components in the shelter category that feeds into the Consumer Price Index (CPI). The CPI tracks the average change over time in prices consumers pay for a basket of goods and services.
This calculation includes rental values, Owners’ Equivalent Rent, and lodging away from home. Together, these drive changes in the overall shelter value. They get influenced by the broader real estate market and monetary factors like interest rates, property taxes, mortgage options, and insurance.
For example, in December 2024, the shelter part of the CPI showed a 0.3% monthly increase and a 4.6% annual rise. Shelter prices led the increases in the CPI that year, alongside medical care, utilities, and transportation services. Overall, the CPI rose by 2.9% across all items in December 2024.
Beyond its role in the CPI, the Bureau of Labor Statistics provides monthly data on OER fluctuations. This is a percentage change that measures shifts in implicit rent—the amount a homeowner would pay to rent or earn from renting their home in a competitive market.
How Do You Calculate Owners' Equivalent Rent?
You calculate Owners' Equivalent Rent through a monthly survey of consumers in their living units. The survey simply asks how much the owner would pay to rent their home instead of owning it.
What Is the CPI Owners' Equivalent of Rent of Residences?
The CPI Owners' Equivalent Rent measures changes in the 'shelter' component of the CPI, along with 'rent of primary residence.' Together, they track the changes consumers face in shelter costs.
What Is CPI to Inflation?
The Consumer Price Index (CPI) measures the rate of change in inflation over time. It's based on the prices U.S. consumers pay for goods and services, and the percentage change in CPI over a period represents inflation.
The Bottom Line
In summary, Owners’ Equivalent Rent (OER) gives you insight into real estate market changes and helps you decide if it's better to buy or rent a property.
