About ToolPinch

Why ToolPinch exists

Questions about money and time are usually simple to ask and annoying to answer: how much of a raise is actually reaching my bank account, how many hours did I work this week once breaks are taken out, which day will I be paid around a holiday, what will I take home in a new country. Many calculators answer with a single number and no explanation. ToolPinch shows the working, the formula, the rules it used and the year those rules apply to, so a result can be checked rather than trusted blindly.

What you will find here

• Pay and tax calculators: take-home pay for the United States, United Kingdom, Canada, Australia, India and Pakistan, a VAT calculator for every country, salary-to-hourly conversion, overtime by state, payday calendars and the 2027 Social Security and federal pay schedules.
• Work hours tools: time cards, break deductions, decimal hours and shift calculations.
• Date and time tools: date differences, business days, countdowns and time zones.
• Everyday math: percentages, discounts, grades, GPA, loans and statistics, each with worked examples.

Where the numbers come from

Tax rates, thresholds and payment dates are taken from the bodies that set them, and each page links to its sources: the IRS and Social Security Administration in the United States, the U.S. Department of Labor and state labor departments for minimum wage and overtime, HMRC in the UK, the Canada Revenue Agency, the Australian Taxation Office, India's Income Tax Department and Pakistan's Federal Board of Revenue. Where a figure comes from a secondary source, such as the Tax Foundation's state tax tables, the page says so.

Every tax page states the tax year it covers. When a government announces new rates, the affected calculators are updated and their date labels changed. Calculations are tested against hand-worked examples before a page is published.

Privacy by design

Calculators run in your browser. Salaries, hours and other values you type are not sent to ToolPinch, and no account is needed. The site uses Google Analytics to count visits and may show advertising; see the privacy policy for details and choices.

How the site is funded

ToolPinch is free to use and is supported by advertising. Advertising never changes a formula or a result, and any sponsored content would be clearly labelled. See the editorial policy and methodology.

What ToolPinch is not

ToolPinch is not payroll software, an employer, a government agency, or a financial, legal or tax adviser. Results are estimates for planning and understanding. For decisions that matter, confirm with your employer, a tax professional or the official source linked on each page.
