Following is an example on how to estimate Household Income and household income as a percent of King County Median Income.

Example
Household has two adults with two children (under 18 years old). One adult receives social security benefits of $955 per month and the other adult has a full time job 40 hours/week paying $15.00/hour.

First Step: Determine your gross household annual income:

Adult 1 $955 per month X 12 months = $11,460

Adult 2 $15/hour X 40 hours/week X 52 weeks/year = $31,200

Total  $11,460 + $31,200 = $42,660

Second Step: Determine your household size 4

Third Step: Determine the median income for your household size on the above chart.

$81,400

Fourth Step: Divide your gross household annual income by the median income for your household size. This is your household income in terms of the King County Median Income.

$42,660/$81,400 = .52 or 52% of Median

For all 'affordable' housing described on this website, eligibility is at least partially based on household income. You must be willing to provide household income information to the property manager. Different types of affordable housing will have different income limits for different size units, and your household income cannot exceed those limits. While different developments have different income limits, all use a similar process for measuring your income. They compare your income to the median (average) household income in King County for a household your size. Your income will then be determined to be a certain percentage of the King County (or Seattle Metropolitan Statistical Area) Median Income.
