Seattle remains an expensive place to live, but the amount you need depends heavily on your housing, transportation, household size, and savings goals. Current 2026 data suggests that a single adult in King County needs about $63,640 in gross annual income to cover basic needs. Renting a typical one-bedroom in Seattle may require a higher income if you want to keep housing near 30% of gross pay.

Seattle Cost of Living at a Glance

The most consistent way to estimate Seattle living expenses is to begin with a broad basic-needs model and then replace its assumptions with your actual rent, commute, insurance, debt payments, and savings target.

Overview of Monthly Expenses for a Single Person

MIT’s Living Wage Calculator estimates that one adult without children in King County needs $53,562 per year after taxes. That equals about $4,464 per month. The estimated required income before taxes is $63,640, or $30.60 per hour for a full-time worker.

This model is broader than a rent-and-groceries budget. Its transportation category may include vehicle ownership and other travel costs, while its housing estimate can differ from the apartment you choose. Replace each row with your actual expected expense before making a move.

A one-adult basic-needs budget in King County is about $4,464 per month after taxes, with housing accounting for nearly half of the modeled total.

Housing and Rental Market: What to Expect

Housing is usually the largest Seattle expense. According to Zillow’s Seattle rental data, the average one-bedroom property was $1,817 per month on July 25, 2026. The average two-bedroom was $2,634 on July 24, while studios averaged about $1,450 earlier that month.

These are citywide listing averages, not guaranteed lease prices. New buildings, furnished units, parking, views, pet rent, and central locations may cost more. Older buildings, income-restricted housing, smaller units, and homes farther from major employment centers may cost less.

Income Needed Under the 30% Rent Guideline

The common 30% guideline compares monthly rent with gross income. It is a budgeting rule rather than a legal limit or guarantee of affordability.

• $1,817 one-bedroom: about $72,680 in gross annual income.
• $2,634 two-bedroom: about $105,360 in gross annual income.
• $1,450 studio: about $58,000 in gross annual income.

Move-In Costs and Deposits

Seattle limits several upfront rental charges. Under the city’s move-in cost rules, the security deposit and nonrefundable fees combined generally cannot exceed one month’s rent. Nonrefundable cleaning and screening fees are also limited, and eligible move-in costs may be paid in installments.

A separate pet deposit of up to 25% of one month’s rent may be charged. Renters should still budget for the first month’s rent, application-related costs, moving expenses, utility setup, furniture, and renters insurance.

Buying a Home

Seattle homeownership remains expensive even though prices have cooled from earlier highs. Zillow reported a typical Seattle home value of $856,052 as of June 30, 2026. Buyers must also account for mortgage interest, property taxes, insurance, repairs, association dues, and closing costs.

Utilities, Groceries, and Everyday Living Costs

There is no reliable universal “Seattle utilities” total because apartment leases divide services differently. Some buildings include water, sewer, and garbage in rent. Others bill tenants through a utility allocation or separate monthly charge. Electricity, internet, and mobile service are often paid directly by the renter.

Electricity

Seattle City Light’s 2026 residential city rate includes an energy charge of about $0.1338 per kilowatt-hour plus a base service charge. City Light reports that its average residential customer uses about 613 kWh per month.

At that usage level, the energy charge plus a $12 base charge is roughly $94 per month before taxes and other adjustments. A small apartment may use less, while electric heat, air conditioning, an electric vehicle, or a larger household may increase the bill.

Water, Sewer, and Garbage

Official 2026 Seattle utility rates show why standalone-house bills should not be used as a universal apartment estimate:

• Residential water has a base charge plus usage-based commodity charges.
• The city’s typical single-family sewer bill is about $86.77 per month in 2026.
• Monthly curbside garbage service starts around $29.20 for a micro-cart and $46.55 for a 32-gallon cart.

Apartment residents often share or indirectly pay these costs, so check the lease for included utilities, allocation formulas, administrative fees, and billing frequency.

Groceries

MIT’s King County model allocates $5,234 per year to food for one adult, equal to about $436 per month. A practical grocery budget may fall between $400 and $550 depending on diet, stores, prepared food, household waste, and how often you eat out.

Food costs also continue to change. The Bureau of Labor Statistics reported that Seattle-area food prices rose 3.5% during the 12 months ending June 2026.

Internet, Mobile Service, and Personal Spending

MIT allocates about $200 per month to internet and mobile service combined. Its model also includes roughly $323 for civic and personal activities and $416 for other necessities. Those categories can include clothing, household supplies, personal care, modest recreation, and similar expenses.

Transportation, Healthcare, and Insurance Expenses

Public Transportation

King County Metro’s standard adult fare is $3 per ride. A monthly PugetPass covering trips valued at up to $3 costs $108. A $99 monthly pass covers trips valued at up to $2.75.

Reduced options can lower this cost:

• ORCA LIFT: $1 per ride for qualifying income-limited riders.
• Senior or qualifying disability fare: $1 per ride with the appropriate reduced-fare card.
• Youth ages 18 and younger: free rides on participating transit services.
• Regional adult day pass: $6 for covered fares up to $3.

MIT’s transportation benchmark is much higher than a transit pass alone: about $8,441 per year, or $703 per month, for one adult. That broader estimate can account for trips, vehicle costs, maintenance, insurance, and other transportation needs.

Driving and Parking

Car ownership may add loan payments, insurance, registration, fuel, maintenance, tires, repairs, tolls, and parking. Apartment parking may also be separate from advertised rent. A transit-friendly location can therefore reduce both transportation and housing-related add-ons.

Healthcare

MIT’s model allocates $3,032 annually, or about $253 per month, to medical expenses for one adult. This is a broad planning estimate rather than the expected price of a particular appointment.

Your actual cost depends on employer contributions, premiums, deductibles, copays, prescriptions, dental and vision coverage, ongoing conditions, and whether providers are in network. Review the full annual cost of a health plan rather than comparing premiums alone.

Insurance

Budget separately for health, renters, and auto insurance. Quotes can differ based on coverage limits, deductibles, claims history, vehicle, address, and other underwriting factors. Request actual quotes before signing a lease or deciding to keep a vehicle.

A $108 transit pass is far below MIT’s $703 monthly transportation benchmark, showing how a car-free lifestyle can materially change a Seattle budget.

Taxes, Minimum Wage, and Take-Home Pay

Washington does not levy an individual state income tax, according to the Washington Department of Revenue. Residents still pay federal income tax, payroll taxes, sales taxes, property-related costs, and other state or local taxes and fees.

Seattle’s minimum wage is $21.30 per hour in 2026. At 40 hours per week for 52 weeks, that equals about $44,304 before taxes.

MIT’s basic-needs living wage for one adult without children is $30.60 per hour, or $63,640 before taxes. A full-time Seattle minimum-wage worker therefore earns roughly $19,336 less than that King County basic-needs benchmark before taxes.

This comparison does not mean every person earning below $63,640 has the same shortfall. Shared housing, subsidized healthcare, employer-paid transit, assistance programs, savings, and household income can change the result.

What Salary You Need to Live Comfortably in Seattle

There is no single salary that guarantees a comfortable Seattle lifestyle. A useful starting point is to separate three questions:

1. Can the income cover modeled basic needs? MIT estimates $63,640 before taxes for one adult without children.
2. Can the income support the chosen rent? The average $1,817 one-bedroom requires about $72,680 in gross income under the 30% guideline.
3. Can the income also fund personal goals? Debt payoff, retirement, travel, dining, premium housing, and emergency savings require additional room.

Is $100,000 Enough for One Person?

For many single adults, $100,000 can support a one-bedroom apartment, normal living expenses, and some savings. The result depends on debt, benefits, transportation, taxes, and lifestyle.

A person earning $100,000 who rents at $1,817 uses about 21.8% of gross income for base rent. However, parking, utilities, loan payments, medical costs, and aggressive savings goals can still reduce the available cushion.

Income Needed for Families

Childcare is one of the largest variables. MIT’s 2026 King County model provides the following required combined household income before taxes:

These are basic-needs estimates. Families paying premium childcare rates, supporting relatives, carrying large debts, or targeting significant savings may need more.

How to Lower Your Cost of Living in Seattle

• Compare total housing costs: Include rent, utilities, parking, pet charges, transit, and commute time.
• Consider a studio or roommate: Sharing a two-bedroom can reduce the cost per person, although the savings depend on the lease and utility split.
• Use public transit: A $108 monthly pass may cost far less than maintaining a car.
• Check reduced-fare eligibility: ORCA LIFT and other programs can reduce transportation costs.
• Review move-in rights: Seattle renters may have the right to pay eligible upfront costs in installments.
• Ask what the rent includes: Water, sewer, garbage, heating, internet, and parking can change the true monthly total.
• Use utility assistance when eligible: Seattle’s Utility Discount Program can reduce qualifying electricity, water, sewer, and garbage bills.
• Build the budget before moving: Use actual insurance quotes, commute costs, benefit deductions, and debt payments instead of relying only on citywide averages.

Frequently Asked Questions

Conclusion

Seattle’s cost of living is driven mainly by housing, but rent alone does not show the full financial picture. MIT’s 2026 King County model places one adult’s basic expenses near $4,464 per month after taxes and the required gross income near $63,640 per year.

A current Seattle one-bedroom averages about $1,817, implying approximately $72,680 in gross income under the 30% rent guideline. A $100,000 salary can provide more flexibility for many single adults, but childcare, debt, car ownership, premium housing, healthcare, and savings goals can raise the amount required.

Use these benchmarks as a starting point. Before moving, replace every estimate with the actual rent, required fees, utility terms, transportation plan, insurance quotes, payroll deductions, and household expenses that apply to you.
