Frequently asked questions
Plain-language answers about when to use the estimate, what your numbers mean, what is left out, and how privacy works.
When should I use the VAT Calculator?
Use it for early planning and side-by-side comparisons, especially for tasks like these: Add VAT to a before-tax price. Remove VAT from a tax-inclusive receipt total. Treat the answer as a planning estimate, not a final quote.
What is the VAT Calculator doing with my numbers?
In plain language: To add VAT, the calculator multiplies net amount by the VAT rate and adds it to the net amount. To remove VAT, it divides the gross amount by one plus the VAT rate. If the result seems too high or too low, first check whether each field expects a monthly amount, annual amount, dollar value, or percent.
What does this estimate leave out?
This uses the manual VAT rate you enter. It does not check country-specific exemptions, invoices, registration rules, reverse charge rules, or tax reporting requirements. Real finance decisions can also depend on fees, timing, local rules, credit details, and provider-specific terms.
Does the site save my finance inputs?
No. The calculator runs in your browser tab. Recent answers stay only on the page while you use it, and they are not sent to a server.
