About mytakehomepay.app

mytakehomepay.app is a free, ad-supported take-home pay calculator. Type a gross salary, pick a country (and a state, Bundesland, or region where it matters), and see the net result broken down into the income-tax bands, social-security contributions, and deductions that produced it — with links straight to the tax authority that publishes each number.

Why this site exists

The big public-facing salary calculators are either thin (a single country, ad-heavy, no breakdown) or paywalled. The official government tools are often slow, mobile-unfriendly, and only cover one jurisdiction. People relocating, comparing offers, or sanity-checking a payslip want one place that handles every country they care about, shows its working, and stays current.

The site is built around three editorial rules:

• Every result is checked against the country’s own reference calculator — HMRC, the BMF, URSSAF, SmartAsset (US), Cinco Días (ES) — with the tolerance documented per country on the methodology page. If you spot a deviation, mail hello@mytakehomepay.app: the fix is the priority.
• No advice language. The calculator estimates. It does not tell you what to do with the result. Where wording would shade into advice, the result page links to the relevant official source instead.
• Inputs never leave the browser.The engine is a plain JavaScript module loaded with the page. Salary figures, country, state, deductions — none of them are transmitted to a server, ever. The privacy notice covers what does get loaded (Google Analytics 4 and AdSense, both gated behind consent).

Who runs it

The site is built and operated by the mytakehomepay.app team, an independent group based in Europe building free web tools alongside other projects. There is no investor — the site is funded entirely by display advertising. That keeps the incentives simple: more accurate results means more repeat visits, which means the calculator stays sustainable.

Editorial decisions, tax-rule updates, and corrections all flow through a small team that reads every inbox. Mail hello@mytakehomepay.appdirectly — questions about a specific calculation get the fastest response.

How the calculator is built

The engine is a deterministic TypeScript module that takes a structured rule set (brackets, allowances, social-contribution rates and caps, regional surcharges) for the target country/region/tax year and produces a typed breakdown. Each country’s rule set is a separate file under version control, kept up to date as the relevant authority publishes new rates.

Continuous integration runs the engine’s output through a suite of golden fixtures — salary-and-expected-net pairs locked against each country’s reference calculator. If a code change drifts the engine more than the published tolerance for any fixture, the build fails before it can ship. Today the suite holds 63 fixtures across five countries; Germany’s 29 are live-scraped from the BMF calculator on demand, the other four are hand-derived from the authority’s published bands and cross-checked against its reference simulator. The methodology pagespells this out per country — the exact reference calculator, the tolerance, and what’s pending.

What’s on the roadmap

Coverage today: United Kingdom, United States (federal + California, New York, Texas, Florida, Illinois), Germany, France and Spain. Next up: the remaining 45 US states, Italy, Netherlands, Ireland, Canada (provinces), and Australia. Sector overlays (NHS pay scales, US W-2 vs 1099, German Beamte) follow once the country list is closer to complete.

Funding & transparency

The site shows display ads from Google AdSense. There are no sponsored calculators, no affiliate links inside the result block, and no paid-placement comparisons — the methodology page lists, for every country, the authority that ranks first in the result’s source link. If the site ever takes affiliate income (e.g. mortgage or pension marketplace links on cluster pages), each placement will be flagged with a visible sponsoredtag and excluded from the calculator’s result panel.
