Assumptions & notes
How is take-home estimated?
We subtract your 401(k) deferral and the standard deduction from salary, apply the 2026 federal income-tax brackets for your filing status, subtract FICA (7.65%), and - if you pick a state - add 2025 state income tax. It's an estimate: local/city taxes, credits and state retirement-income exclusions aren't modeled, so your real paycheck may differ.
Why does saving more cost less than it seems?
Traditional 401(k) contributions come out before income tax. If you're in the 22% bracket, a $100 contribution only reduces take-home by about $78 - the other $22 was tax you'd have paid anyway.
How accurate is the state tax?
We apply each state's published income-tax brackets and standard deduction. See our
methodology for sources and the states still pending verification. Always confirm with your state's Department of Revenue.
These are assumptions, not guarantees. Investment returns and inflation are estimates you control - markets vary and past performance does not predict future results. Tax figures use current-year IRS numbers; your situation may differ. This tool is educational and not financial advice.
