Fair Market Rent Calculation Methodology
Show/Hide Methodology Narrative
Fair Market Rents for metropolitan areas and nonmetropolitan FMR areas are developed as follows:
 20112015 5year American Community Survey (ACS) estimates of 2bedroom adjusted standard quality gross rents calculated for each FMR area are used as the new basis for FY2018.
In areas where the 20112015 5year ACS 2bedroom adjusted standard quality gross rent estimate is less than its respective margin of error, the state nonmetro estimate of 2bedroom adjusted standard quality gross rent is used.
 HUD calculates a recent mover adjustment factor by comparing a 2015 1year 40th percentile recent mover 2bedroom rent to the 20112015 5year 40th percentile adjusted standard quality gross rent. If either the recent mover and nonrecent mover rent estimates has a margin of error that includes zero, HUD uses the recent mover adjustment for a larger geography. For metropolitan areas, the order of geographies examined is: FMR Area, Entire Metropolitan Area (for Metropolitan SubAreas), State Metropolitan Portion, Entire State, and Entire US; for nonmetropolitan areas, the order of geographies examined is: FMR Area, State NonMetropolitan Portion, Entire State, and Entire US. The recent mover adjustment factor is floored at one.
 HUD calculates the appropriate recent mover adjustment factor between the 5year data and the 1year data and applies this to the 5year base rent estimate.
 Rents are calculated as of December 2016 using the relevant (regional or local) change in CPI from annual 2015 to annual 2016 as well as the change in national CPI from annual 2016 to December 2016.
 All estimates are then trended from December 2016 to April 2018 (15 months) with a trending factor of 2.2999% per year.
 The FY2018 FMR is then calculated by multiplying the base rent, the recent mover adjustment factor, the CPI adjustment, and the trend factor.
 FY2018 FMRs are then compared to a state minimum rent, and any area whose preliminary FMR falls below this value is raised to the level of the state minimum.

A recent mover adjustment factor is applied based on the smallest area of geography which contains and has an ACS_{2015} 1year Adjusted Standard Quality RecentMover estimate with a Margin of Error Ratio that is less than 1.

The calculation of the relevant CPI Update Factors for is as follows:
HUD updates the 2015 intermediate rent with the ratio of the annual 2016 local or regional CPI to the annual 2015 local or regional CPI to establish rents as of 2016.
HUD then updates this 2016 annual CPI with the ratio of the December 2016 national CPI to the annual 2015 national CPI to establish rents as of December 2016.

The calculation of the Trend Factor is as follows:
HUD applies an additional 15 months of trending to update rents to April, 2018, the midpoint of FY 2018. This trend factor is determined by taking the average annual growth rate in the national 1Year Median Gross Rent between the 2010 and 2015 American Community Surveys.

In keeping with HUD policy, the preliminary FY 2018 FMR is checked to ensure that is does not fall below the state minimum for :

The following table shows the FY 2018 FMRs by bedroom sizes. The FMRs for units with different numbers of bedrooms are computed from the ratio of the 40^{th} percentile adjusted standard quality gross rent for the different unit sizes to the 40^{th} percentile adjusted standard quality 2Bedroom gross rent from the 20062010 5year ACS. These Rent Ratios are applied to the FY 2018 2Bedroom FMR to determine the FY 2018 FMRs for the different size units.

The FMRs for unit sizes larger than four bedrooms are calculated by adding 15 percent to the four bedroom FMR, for each extra bedroom. For example, the FMR for a five bedroom unit is 1.15 times the four bedroom FMR, and the FMR for a six bedroom unit is 1.30 times the four bedroom FMR. FMRs for singleroom occupancy units are 0.75 times the zero bedroom (efficiency) FMR.
