Every calculator on TechLab247 is an estimator for educational purposes. Nothing on this site is tax, legal, accounting, financial or investment advice, and no professional-client relationship is created by using it.

Why an accurate calculator can still be the wrong answer

Tax outcomes depend on facts a general-purpose calculator cannot know: your registration status, product classification, customer type, thresholds you have or haven't crossed, exemptions, and the specific rules of each jurisdiction. A correctly calculated 19% VAT amount is still wrong if the correct treatment for your sale was a reduced rate, a reverse charge, or no VAT at all. Financing calculators model standard structures; a real credit agreement's terms prevail.

What we promise instead

We keep the rates sourced from official publications, cite the source and the last-checked date on every tool, show a visible warning when data passes its review window, document every formula with a worked example, and correct verified errors promptly under our editorial policy.

Before filing, invoicing, charging tax or signing a financing agreement, verify with the relevant tax authority, the counterparty's official schedule, or a qualified professional.
