Owners’ Equivalent Rent (OER)


Owners’ Equivalent Rent (OER) is a term used in economics and real estate, specifically in calculating the Consumer Price Index (CPI). It estimates how much it would cost to rent a home similar to the one an owner lives in rather than owning it. The purpose of OER is to include the cost of shelter for homeowners in the CPI accurately.


Owners’ Equivalent Rent (OER) is phonetically pronounced as: “OH- nuhrs – ih-KWIV-uh-luhnt – rent”

Key Takeaways

  1. Definition: Owners’ Equivalent Rent (OER) is a measure used by the Bureau of Labor Statistics to record the estimated amount that homeowners would pay in rent if they were to rent their homes rather than own them. This measure serves as an attempt to understand and account for housing cost inflation.
  2. Contribution to CPI: OER contributes significantly to the Consumer Price Index (CPI), which is a critical measure of the overall inflation. In fact, it is one of the largest components of the CPI’s housing section, and thus, significant fluctuations in OER can drastically affect CPI measurements. This makes understanding and monitoring OER essential for economic analysis.
  3. Criticism: The method of calculating OER has faced some criticism for being theoretical rather than grounded in actual market rents. Critics feel it may not accurately reflect the changes in housing costs experienced by homeowners, especially during housing market volatility. However, the Bureau of Labor Statistics continues its use because it allows them to avoid drastic fluctuations that might be caused by home price volatility.


Owners’ Equivalent Rent (OER) is a key concept in finance and economics that has substantial implications on economic indices and measures of inflation. OER is essentially an estimation of how much it would cost someone to rent their own home if they were not already living in it. It constitutes a significant part of the Consumer Price Index (CPI), a critical economic indicator used by policymakers and economists to measure inflation and make monetary and fiscal decisions. Since homeowners constitute a considerable segment of the population in many economies, fluctuations in the OER can noticeably sway the overall CPI. Therefore, housing market trends, market rental rates, and consequent changes to the OER have substantial impacts on economic analysis and strategy. It helps provide a more accurate reflection of household costs and overall cost of living. Therefore, understanding and monitoring OER is vital for both microeconomic and macroeconomic analysis.


Owners’ Equivalent Rent (OER) serves as a crucial aspect in the measurement and understanding of inflation in an economy. It is commonly used by statisticians and economists who calculate national inflation figures. The concept is based on the amount that homeowners would have to pay if they were renting their homes rather than owning them. This captures the notion that homeowners implicitly pay rent to themselves as they forego the income that could have been earned by renting the property to others. Thus, OER attempts to provide a comparable measure for the costs faced by homeowners and renters alike. Moreover, OER is vital as it constitutes a significant portion of the Consumer Price Index (CPI), the primary tool utilized by governments across the world to gauge inflation. In the US, for example, it accounts for nearly a quarter of the overall CPI, making it a critical determinant of governmental economic policies. Adjustments made based on inflation, such as Social Security benefits, tax brackets, and Federal Reserve policies, heavily rely on the accuracy of OER. Therefore, despite being a fairly complex concept, OER plays a central role in understanding and managing the financial health of an economy.


1. Residential Property: Suppose John owns a two-bedroom apartment. Instead of renting it out, he decides to live in it himself. In this case, the owners’ equivalent rent (OER) is how much John could reasonably expect to receive if he were to rent out his apartment to other tenants, considering the rental market prices in his area for similar properties.2. Vacation Home: Another situation could be with vacation homes. For instance, Sarah owns a beautiful beach house which she occasionally uses during holidays. Even though she doesn’t rent it out, she could calculate the OER based on what she could potentially charge for it as a vacation rental during prime holiday periods.3. Commercial Property: Another real-world example of OER applies in the case of a business owner who operates their business from a building they own. The business owner could calculate the OER by figuring out the rent he or she would have to pay to lease a comparable commercial building in the same location. This value could then be used to represent a kind of implicit rent expenditure in the company’s financial planning.

Frequently Asked Questions(FAQ)

What is Owners’ Equivalent Rent (OER)?

Owners’ Equivalent Rent (OER) is a statistic that is used by economists and real estate professionals to estimate the amount a homeowner would have to pay to rent their own home at a market rate.

How is OER calculated?

OER is calculated by using various data such as local market rent prices, changes in the rental market, and homeowner estimates of what their homes would rent for.

Why is OER important in economics?

OER is a significant component of the Consumer Price Index (CPI). It indicates changes in the rental value of homes and plays a crucial role in measuring inflation in the economy.

Does the OER include the cost of utilities or other expenses?

No, OER is strictly the estimated rental cost of the property, it doesn’t include costs like utilities, repairs, insurance or taxes.

How often is the OER updated?

The OER is updated regularly, typically on a monthly basis, by the Bureau of Labor Statistics.

Can OER be used as an investment indicator?

Yes, investors often monitor changes in OER as a potential sign of changes in property values, housing demand, or investment opportunities in the real estate sector.

What is the difference between OER and Rent of Primary Residence?

OER considers the estimated rent a homeowner would pay to rent their home, while Rent of Primary Residence measures the actual rent people are paying for their primary residence.

How does the OER affect homeowners?

Since the OER is a significant component of the CPI, changes in the OER can impact government policies, especially those related to inflation, which can indirectly affect homeowners. For example, higher inflation could mean higher interest rates, which can influence the cost of new mortgages and the value of houses.

Does OER apply to commercial properties?

No, OER is primarily used for residential properties. The concept is to estimate the amount a homeowner would have to pay to rent their own home at a market rate. Commercial properties operate on different factors and are not usually included in OER calculations.

Is the OER applicable globally?

While the concept of OER is universal, its usage and impact can vary by country. Different countries may use different methods to estimate rental values and incorporate them into their economic measurements.
