About Paymappr

Paymappr is a free, privacy-first paycheck and salary calculator covering the four largest English-speaking tax systems: the United States, United Kingdom, Canada, and Australia.

Why we built this

Figuring out how much of your paycheck you actually keep shouldn't require a spreadsheet or a CPA. Existing tools either bury results under sign-up walls, limit you to one country, or require hundreds of inputs before giving you a number. Paymappr is the opposite: open the calculator, enter your salary, see your take-home. That's it.

What makes us different

• Multi-country, one tool. Switch between US (all 50 states), UK (England, Scotland, Wales, Northern Ireland), Canada (13 provinces and territories), and Australia (8 states and territories) with a single tab.
• Privacy by design. All calculations run in your browser using static JavaScript. Your salary never reaches our servers. No account. No email. No tracking of inputs.
• Official sources, always cited. Every state, province, and region page links to the official revenue authority (IRS, HMRC, CRA, ATO, and their regional counterparts).
• Fast. Pages are pre-rendered as static HTML and served from Cloudflare's global edge. Your calculator loads before the ads do.
• Open formulas. Bracket tables are published on every page so you can verify our math yourself.

How we stay free

Paymappr is supported by Google AdSense advertising. We place a small number of clearly-marked ads around the calculator and in long-form content. We never sell or share your input data (we don't even collect it). We don't show paywalls, gate results behind email sign-ups, or require accounts.

How rates are updated

We monitor tax authority publications and update brackets within days of release. The current version uses:

• US: IRS Revenue Procedure 2025-32 (2026 inflation adjustments), SSA 2026 wage base projection, and 2026 projected state rates.
• UK: HMRC 2025/26 Income Tax bands and Class 1 NI rates; Scottish 2025/26 rates from the Scottish Government.
• Canada: CRA 2025 federal brackets indexed to 2026, provincial/territorial 2025/26 rates.
• Australia: ATO 2025–26 resident individual rates, Medicare Levy, and HELP thresholds.

Limitations

Paymappr estimates wage-equivalent taxes for standard employment (W-2 in the US, PAYE in the UK, T4 in Canada, standard PAYG in Australia). We do not calculate:

• Capital gains, dividends, or other non-wage income.
• Full self-employment tax returns (Schedule C, SE, etc.) — our self-employed pages show the main principles but not the full filing.
• City, county, or municipal income taxes (flagged in text where they apply, not auto-calculated).
• Tax credits beyond the basic standard deduction or personal allowance.
