A web-based paycheck calculator has been built to reflect the latest 2025 federal and state tax policies across all 50 US states. It estimates after-tax income by accounting for federal, state, and FICA deductions, and supports different pay frequencies (weekly, bi-weekly, monthly, etc.).

The intent is to provide an up-to-date, lightweight tool for anyone trying to quickly understand take-home pay. The design goal was simplicity: one page, minimal inputs, instant breakdown.

Questions for the community: • What additional features would actually make this more useful (e.g., 401k, health deductions, local taxes)? • Would people prefer a simple “quick estimate” vs. a more configurable advanced mode? • From a technical/product perspective, what would you change or add?

Feedback is welcome, especially from those who have dealt with paycheck calculators before or have strong opinions on usability.
