How This VAT and Sales Tax Calculator Works
This simple single-rate calculator adds or removes the VAT, GST, or sales-tax percentage you enter. It does not select a legal rate or model stacked taxes and exemptions.
Formula and Calculation
The core formula used by this vat and sales tax calculator is: Tax amount = Net price x Tax rate. Gross price = Net price + Tax amount.
To remove VAT from a gross amount, divide by (1 + tax rate). This isolates the pre-tax value and implied tax component.
If a supplier quote is tax-inclusive, enter its stated tax rate to estimate the base value and included tax. Classification, exemptions, stacked taxes, and official rounding remain outside the estimate.
How to Use This Calculator
- Enter net or gross amount based on your use case.
- Enter the applicable percentage from the invoice or tax authority.
- Choose add-tax or remove-tax mode.
