How to Use AfterTaxLab: Pick the Right Tool for Your Question
AfterTaxLab tek bir hesap makinesi değil, birbirine bağlı on iki araçtan oluşan bir platformdur. Her araç tek bir soruya odaklanır ve hepsi aynı 2026 vergi motorunu, aynı BLS hane harcama verisini ve aynı BEA fiyat endeksini kullanır. Aşağıdaki tablo hangi sorunun hangi araçla yanıtlandığını gösterir.
What AfterTaxLab is
AfterTaxLab is a set of linked tools built on one calculation engine and one set of public data sources. Every page answers a specific question about income and cost of living — what a salary leaves after tax, how states compare, what rent a city requires, what an occupation pays, what a household actually keeps. Because they share the same engine and the same underlying data, the numbers on different pages agree with each other rather than drifting apart.
The site is designed around one principle: a salary figure alone is not an answer. The useful number is what remains after tax and after the cost of living where you intend to live, and that number changes with three variables — location, income level and household type. Each tool isolates one of those variables so it can be examined clearly.
What data the tools use
- The tax engine. 2026 federal brackets, the $16,100 single and $32,200 joint standard deductions, Social Security at 6.2 percent up to the $184,500 wage cap, Medicare at 1.45 percent plus 0.9 percent above $200,000, and each state's own income tax structure.
- Living costs. The BLS Consumer Expenditure Survey, which measures what American households actually spend, combined with BEA Regional Price Parities, which measure how much the same basket costs in each state.
- Rent. Zillow Research ZORI metro averages, tracking typical observed rent rather than asking prices.
- Wages by occupation. BLS Occupational Employment and Wage Statistics, including the 10th, 25th, 50th, 75th and 90th percentile of each occupation's pay distribution.
- International comparison. OECD Taxing Wages, which applies one standardised methodology to every country it covers.
How the pages fit together
The salary page answers the most basic question: what does this salary leave after tax, and how does it differ by state and filing status. The state and city pages add geography — first at the level of tax and price parities, then at the level of actual rents. The career page adds occupation, using BLS percentile data so entry-level and senior pay are visible rather than flattened into a single average. The family page adds household structure. The relocation and international pages put two locations side by side. The affordability and salary journey pages bring the whole sequence together: gross pay, tax, take-home, living costs and what remains.
Updating and accuracy
Public data series are revised on their own schedules: tax parameters change annually, the BLS spending survey is released each year, price parities are updated periodically and rent indices monthly. This site tracks those sources and regenerates its tables when new values appear, rather than freezing numbers at the date a page was written. If a source has not published a new release, the page keeps using the most recent available one and says which year it refers to.
What this site is not
These tools are calculators, not tax advice. They model the common case — wage income, standard deduction, no itemised deductions, no credits — which covers most but not all situations. Households with self-employment income, significant investment income, itemised deductions or credits will see different results, and a qualified tax professional is the right source for those cases. What the site provides is a transparent, consistent baseline that makes comparisons possible and shows exactly which numbers drive the outcome.

Start with the salary page for take-home pay, then the state or city page for geography, then the family or affordability page if your household structure matters. The table above maps each question to the tool that answers it.
How often is the data updated?
