What is a Mortgage Calculator?
A mortgage calculator helps you estimate your total monthly housing payment, including principal, interest, property taxes, home insurance, and private mortgage insurance (PMI). This gives you a complete picture of what homeownership will cost each month.
Unlike a simple loan calculator, a mortgage calculator accounts for additional costs that come with buying a home. Property taxes and insurance are typically required by lenders to be included in your monthly payment through an escrow account.
All calculations happen in your browser. No financial data is sent to any server, so your information stays completely private.

What Makes Buying in Washington Different
Washington State charges no personal income tax, which is a strong advantage for high earners in Seattle and Bellevue working at Microsoft, Amazon, and Meta. The tradeoff shows up at transaction time through the Real Estate Excise Tax (REET), a graduated transfer tax that hits 1.1% on sale prices up to $525,000 and climbs to 3% on amounts over $3.025 million. On a median home in King County, REET alone can exceed $8,000. Property taxes are moderate at 0.87% effective on a median $580,000 home, though King County and Snohomish County push higher. Homeowners insurance averages around $950 per year, which is low nationally, but wildfire exposure east of the Cascades has started to pressure rates in parts of Central Washington. Washington's homestead exemption is unusual: rather than a fixed dollar amount, it equals the county's median sale price for a single-family dwelling. In King County, that currently means over $700,000 in home equity is protected from most creditors. The combination of no state income tax, moderate property tax, and high home prices creates a specific affordability pattern: buyers can qualify for more mortgage than they could in an income-tax state, but the home prices in the Puget Sound region absorb that advantage.
Top Cities in Washington
| City | Median Home Value |
|---|---|
| Seattle | $875,000 |
| Bellevue | $1,525,000 |
| Spokane | $410,000 |
| Tacoma | $495,000 |
| Vancouver | $525,000 |
REET is a graduated transfer tax on real estate sales paid by the seller in most cases. State rates are: 1.1% on sale prices up to $525,000, 1.28% from $525,001 to $1,525,000, 2.75% from $1,525,001 to $3,025,000, and 3% on amounts over $3,025,000. Cities and counties often add local REET on top of the state portion. On a median King County home, REET alone exceeds $8,000. While the seller typically pays, the tax ultimately factors into market pricing.
Washington does not have a state income tax on wages, making it attractive to high earners at Microsoft, Amazon, Meta, and Boeing. There is a 7% capital gains tax on long-term gains over $270,000, which applies to stock sales but not salary. Lenders use gross income for DTI calculation, but Washington buyers effectively have more after-tax income for housing compared to same-salary earners in California or New York.
Washington's homestead exemption is unusual: it equals the county's median sale price for a single-family dwelling, which adjusts over time. In King County, this currently protects over $700,000 of home equity from most creditor claims. You do not need to file; the exemption is automatic when the property is your principal residence. This is one of the strongest homestead protections in the US for high-cost counties.
The statewide average effective rate is 0.87%, but King County runs closer to 1.0% and Snohomish County above that. On a $580,000 median home at the state average, annual property tax works out to roughly $5,050. Washington's tax system is split across state school levies, local school bonds, city levies, and fire district assessments; the total rate varies house to house within the same county.
The Puget Sound region (Seattle, Bellevue, Redmond) has median home prices $400,000 to $600,000 higher than the state average due to tech-industry employment concentration. Bellevue and Mercer Island now exceed $1.5 million median. Meanwhile, Spokane and Yakima in eastern Washington have medians closer to $400,000. The no-income-tax advantage is most valuable in the high-cost Puget Sound region, where the saved state income tax on Microsoft or Amazon wages can fund a significantly larger mortgage.
