Abacus Financial Planning


I give clients the information, analysis, and guidance they need to move forward with financial decisions. - Katy Cook, Ph.D.

Hourly and project planning for stock awards, stock options, and building a DIY paycheck for retirement. Located in Kirkland, WA, serving clients locally and across the country.

Katy Cook is a fee-only financial planner located in Kirkland, WA and serving the Seattle area and clients across the country.  Abacus Financial Planning provides comprehensive and objective financial planning, investment management services and retirement planning to help women, their families, and people historically underserved by the financial industry organize, grow and protect their assets through life’s transitions. As a fee-only, fiduciary, and independent financial advisor, Katy Cook is never paid a commission of any kind, and has a legal obligation to provide unbiased and trustworthy financial advice.

Katy Cook is a Principal at Abacus Financial Planning and decided to change careers and go into financial planning after creating her parents’ retirement plan. She saw firsthand the peace of mind that comes with having a roadmap to guide investing and spending decisions. She has also seen how that plan can be tested with health concerns and a global pandemic.

Katy helps women, their families, and anyone historically underserved by the financial industry use money to live the life they want. She enjoys helping people explore financial scenarios and understand the long-term impact of small (and large) choices.

Prior to being a financial planner, Katy spent a decade in teaching and independent consulting focused on “data for do-gooders.” She completed a BS in Mathematics at the University of Texas at Austin and a financial planning certificate with Boston University. She holds a Ph.D. in Applied Mathematics from Princeton University, where she was a National Science Foundation Graduate Research Fellow.

While teaching, Katy gravitated to the “guide on the side” model of teaching, rather than the “sage on the stage” model. This is a great fit in financial planning, where Katy provides gentle support on the side. She continues to teach finance and business classes at Southern New Hampshire University.

Katy volunteers with non-profit organizations that support children, family health, and education through board and committee work. She previously served in AmeriCorps offering financial support services for people with low income or developmental disabilities. She serves as a volunteer tax preparer, though you can’t pay her enough money to do your taxes.

Katy enjoys spending time with her friends and family, and on weekends, you can find her sorting Lego pieces into 25 categories.
