Disclaimer

Last updated October 10, 2026

The calculators and articles on CheckMySum give estimates and general information. They are not tax, legal, accounting, investment or financial advice, and using the site does not make you our client.

Results are estimates

Every calculator makes assumptions, and each page states them. A calculator cannot see your full situation: other income, credits, deductions, benefits, your contract, or the rules of your state or your employer's plan. Your real pay, tax bill or account balance can differ from the result shown.

Tax figures

Tax rates, limits and thresholds are taken from official sources and dated on each page. Governments change them, sometimes during the year. Always confirm with the tax authority, such as the IRS in the United States or HMRC in the United Kingdom, or with a qualified tax professional, before you file a return or make a payment.

Savings and investment figures

Projections of savings and investments use the interest rate or return that you enter. They are illustrations, not forecasts. Returns are not guaranteed, and investments can lose value. Nothing on this site is a recommendation to buy, sell or hold any investment or financial product.

Employment and pay rules

Pages about overtime, minimum wage, holiday entitlement and employment status describe the general rules. Whether a rule applies to you depends on your job, your contract and where you work. For a dispute or a decision about your status, contact the relevant government agency or an employment adviser.

Advertising

The site is paid for by advertising. Adverts are chosen by the advertising network, not by us, and are not recommendations.

Mistakes

If you think a figure or a result is wrong, please tell us. We check every report against the official source.
