University of Washington School of Dentistry Cost: The Full 4-Year Breakdown

The University of Washington School of Dentistry, in Seattle, is one of the more expensive paths to a DDS in the country — it ranks #61 cheapest of the 64 schools in our cost dataset, which is another way of saying it is the 4th priciest, at the out-of-state rate. Based on cost-of-attendance data from around 2021–2022, four years there ran about $518,749 before interest. Below is the year-by-year breakdown, what it really costs once student-loan interest is counted, and why your DAT score is the single biggest lever on this number.

On these figures: the dollar amounts come from published cost-of-attendance data from roughly 2021–2022, and largely reflect the out-of-state or listed rate. Tuition and living costs rise about 3–5% a year, so the current 2026 total is likely 15–20% higher — our inflation-adjusted estimate is ~$607,000. Treat every number here as a planning estimate, and confirm the current figure directly with the school and at ada.org.

University of Washington dental school cost, year by year

Cost of attendance combines tuition & fees with the school-published cost of living (housing, food, transportation, supplies). Here is how the four years broke down in the source data:

Two things stand out. First, tuition sits above $94,000 every single year and peaks in Year 2 — there is no cheap year here. Second, this is the out-of-state figure, and Seattle's high cost of living pushes the annual living allowance close to $30,000, well above what students face in lower-cost cities. Washington residents pay meaningfully less, which is exactly why in-state status matters so much at UW.

The number nobody shows you: cost with loan interest

Sticker cost of attendance is not what you repay. Most dental students finance with federal Direct and Grad PLUS loans that accrue interest while you are still in school. Once you fold that in, the UW four-year total climbs to roughly $661,221 — about $142,000 more than the sticker figure, before you have made a single payment. That interest gap alone is larger than the entire four-year cost of attendance at the cheapest schools in our dataset. It is the quietest, largest line item in dental education, and it is exactly why a higher-priced school compounds against you.

How your DAT score changes this number

Here is the connection students miss: the DAT is the cheapest lever on the most expensive purchase of your life. A stronger DAT score widens the set of schools that will admit you — including your in-state public school and any school offering merit scholarships. Moving from an out-of-state seat at a school like UW to an in-state public seat, or securing UW's own in-state tuition, can swing your total by $100,000 to $280,000. The exam that unlocks that difference costs a few hundred dollars. No other single decision in your pre-dental years has that kind of return.

That is the entire premise of DATPractice: be the highest-ROI, lowest-cost part of your journey. Do every practice test, understand every question, and walk in with a score that gives you the choice of the cheapest, best-fit school — instead of taking the only seat you can get.

How to pay less at University of Washington (or anywhere)

• Establish Washington residency if you can — in-state tuition is the biggest single discount available at a public school like UW.
• Maximize your DAT to open scholarship and in-state options before you ever apply.
• Apply early through ADEA AADSAS; later applicants compete for fewer seats and less aid.
• Budget carefully in Seattle — the local cost of living drives a large share of this total, and it is one line you can partly control.
• Borrow only cost-of-attendance, and understand Grad PLUS interest accrues immediately.
• Compare total cost with interest, not sticker tuition, when you weigh acceptances.
