About this tool

Seattle-area prices put heavy weight on the loan side of a Washington purchase, and that is the side this calculator isolates. Supply a price, down payment, rate and term, and it returns the monthly principal and interest together with the loan amount, cumulative interest and lifetime total. With the default 600,000 price and 120,000 down, the 480,000 dollar loan at 6.5 percent over 30 years costs about 3,034 dollars monthly and carries roughly 612,000 dollars of interest. Washington charges no income tax on wages, which stretches budgets further, while the payment here deliberately ignores property tax and insurance, both of which are significant in the Puget Sound counties. Figures are principal and interest estimates derived from your inputs; Washington taxes, insurance and HOA costs are excluded. Verify with official sources. Not financial or lending advice.Sellers in Washington pay a graduated state excise tax on sale that starts near 1.1 percent and steps higher for pricier transactions (approximate; brackets have been adjusted in recent years). Effective property tax rates run roughly 0.7 to 1.1 percent depending on the county (approximate). Escrow totals therefore climb quickly in King and Snohomish counties. Verify current figures with the Department of Revenue and your county assessor; all results here are estimates.
