General information only

The calculators and content on Calculatorza are provided for general informational and educational purposes. While we aim for complete accuracy, we make no guarantees about the completeness or reliability of any result.

Exchange rates

Currency conversions use mid-market reference rates from a third-party provider, updated about once a day. Banks, card providers and money-transfer services usually apply their own rates and fees, so the amount you actually receive or pay will differ. Always confirm the final rate with your provider before a transaction.

Not professional advice

Results from the discount, sales tax, tip, profit and other calculators are not financial, tax, accounting or legal advice. Tax rules, rounding methods and grading scales vary by country, institution and organisation. Please consult a qualified professional or your institution's official rules before making important decisions.

Rounding

Results are rounded for display (up to 4 decimal places for percentages and 2 for money). Official documents such as invoices or mark sheets may use different rounding rules.

Grades

Letter grades shown by the marks and grade calculators use a common A–F scale (A 90%+, B 80%+, C 70%+, D 60%+). They are not official grades.

Advertising and affiliate links

Some links and banners on this site may be advertisements or affiliate links, which means we may earn a commission if you click them or make a purchase, at no extra cost to you. This never changes how our calculators work or the results they give. Read our full Affiliate Disclosure.
