Living comfortably in Seattle means more than covering rent — it means your essentials fit inside a healthy budget with room left to save. This calculator applies the 50/30/20 rule to realistic Seattle costs and grosses the result back up for taxes to show the annual salary you actually need.
How it works
The tool sums your monthly needs, expands them to a full budget under the 50/30/20 rule, then converts net to gross:
monthly needs = rent + utilities + transit + groceries + other
monthly net = monthly needs / (needs % / 100) ← 50% by default
annual net = monthly net × 12
required salary = annual net / (1 − effective tax rate)Because needs are only 50% of a balanced budget, total spending power is double your essentials, leaving 30% for wants and 20% for savings. Washington has no state income tax, so the gross-up uses a lower effective rate than high-tax states — typically around 22% for federal plus FICA at this income.
Example and tips
A single person paying $2,100 rent, $200 utilities, $99 transit, $450 groceries, and $250 other essentials has about $3,099 in monthly needs. Under the 50% rule that requires roughly $6,198 net a month, or about $74,400 net a year — grossing up at a 22% effective rate gives a required salary near $95,000. Splitting a two-bedroom with a roommate is the single fastest way to cut that figure, since housing is by far the largest line.
