Show HN: A paycheck calculator for all 50 US states with 2025 tax rules
paycheckcalc.appA 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. What does this calculator provide that I can't get from just examining my most recent paystub, which is also one page or less, no inputs, and instant breakdown? Also, federal and state income tax withholding is just an estimate, not your actual tax liability. It does not take into account other income or deductions or credits that your employer knows nothing about.
