About Patricia Chen
Patricia Chen owns dangcash's calculator library: retirement, tax, debt, salary and savings tools, and the written assumptions under each one. She authors the method cards that explain every formula in plain language, documents where each rate or limit comes from, and keeps the worked examples in step whenever an input changes - so the number on the screen and the explanation beside it never drift apart.
Her planning guides focus on decisions readers can act on: how much to save, when refinancing pays for itself, what a paycheck actually keeps after tax. Calculator outputs are estimates, and every page says so - each one links the official source (IRS publications, CFPB explainers, program rules) so a reader can confirm the figure before committing money to it.
