Before signing a Seattle lease, it pays to check the rent against your income. This calculator applies the widely used 30%-of-income rule, benchmarks the rent against Seattle’s roughly $2,100 median one-bedroom, and tells you which neighborhood tier your budget realistically supports.
How it works
The 30% rule caps rent at 30% of gross monthly income; the tool compares your proposed rent to that cap:
monthly income = annual income / 12
max rent (30%) = monthly income × 0.30
rent-to-income % = proposed rent / monthly income × 100
A ratio at or under 30% is affordable, 30% to 50% is rent-burdened, and above 50% is severely rent-burdened. The tool also maps your maximum affordable rent onto Seattle neighborhood tiers — from outlying areas below the median up to premium core neighborhoods well above it.
Example and tips
On a $90,000 gross salary, monthly income is $7,500 and the 30% cap is $2,250 a month — enough for a median Seattle one-bedroom at $2,100 (a 28% ratio, comfortably affordable). Push the rent to $3,000 and the ratio jumps to 40%, which is rent-burdened and leaves little for savings. If your target rent exceeds your cap, splitting a unit with a roommate roughly halves your share and is the quickest way back under 30%.
