It allocates 60% of gross income to the origin city’s category budget and applies each destination category’s relative cost. The equivalent salary adds the total category difference to your income. The monthly difference is the same category difference divided by 12; it is not take-home pay or guaranteed savings.

What rent estimates are available for Maple Valley, WA and Lake Oswego, OR?

The modeled two-bedroom rents are $2,850/month in Maple Valley, WA and $2,295/month in Lake Oswego, OR.
