About Paycheck & COL Hub

Every year, millions of professionals evaluate job offers, plan relocations, or simply wonder how much of their salary they actually keep after taxes. The challenge? Tax rules differ by country, state, and even city—and cost of living can turn a “bigger” salary into less purchasing power.

Paycheck & COL Hub exists to make that comparison effortless. We built a net salary calculator, a cost of living calculator, and a job offer compare calculator so you can see, in minutes, what a salary is really worth—after tax, after rent, after groceries. No sign-up, no paywall. Just clear numbers.

Our salary and tax calculations are built on publicly available, government-published tax brackets and social-contribution rates for each country and region we support. Here is a summary of our methodology:

• United States: We apply current federal income tax brackets (10 %–37 %), Social Security (6.2 % up to the wage cap), Medicare (1.45 %), plus state income tax for every state we cover—including California, New York, Texas, Florida, Illinois, Washington, and more. For states with no income tax (TX, FL, WA, etc.) the state component is zero, making the comparison immediately clear.
• United Kingdom: We use the current personal allowance, basic-rate, higher-rate, and additional-rate bands, plus National Insurance contributions. Scotland has separate bands and rates, which we handle independently.
• Germany: We apply the standard German income tax formula (Einkommensteuer) and the four main social contributions: pension insurance (Rentenversicherung), health insurance (Krankenversicherung), unemployment insurance (Arbeitslosenversicherung), and long-term care insurance (Pflegeversicherung).

Cost-of-living comparisons use relative price indices for housing, groceries, transport, and general expenses across major cities. We cross-reference multiple data points to produce a single, intuitive equivalent-salary figure.

Transparency matters. We source our tax data from official government publications:

• US: Internal Revenue Service (IRS) and individual state tax authority websites (e.g., California Franchise Tax Board, New York State Department of Taxation and Finance).
• UK: HM Revenue & Customs (HMRC) and National Insurance rate tables.
• Germany: Bundesministerium der Finanzen (BMF) and the social insurance contribution schedules published annually.

Cost-of-living indices are derived from aggregated consumer-price data, housing-market reports, and publicly available city-level statistics. We update our data regularly, though we cannot guarantee real-time accuracy—see our Disclaimer for important caveats.

Every guide and calculator on this site follows a set of principles:

• Accuracy first: We cross-check tax rates against official sources before publishing and update them when new rates are announced.
• Transparency: We explain our assumptions (e.g., single filer, no extra deductions) so you know exactly what the numbers represent.
• No hidden agenda: Our guides are written to inform, not to sell you anything. Advertising (via Google AdSense) helps keep the tools free, but it never influences our calculations or editorial content.
• Regular updates: Tax law changes every year. We review and update our data at least annually for each country we support.
• Not advice: We always make it clear that our results are estimates for planning and comparison—never a substitute for professional tax, financial, or legal advice.

Paycheck & COL Hub was created by a small team of finance enthusiasts and software engineers who have navigated cross-border job changes themselves. We have lived and worked across the US, UK, and Europe—and we understand how confusing it can be to compare a salary in dollars, pounds, and euros while factoring in wildly different tax systems and living costs.

We built the tools we wished existed when we were making our own relocation decisions. Today, thousands of people use Paycheck & COL Hub every month to plan moves, evaluate offers, and understand their financial picture. We are committed to keeping the tools free and continuously improving them.
