Guide: Sales Tax Calculator

What it does

Converts between pre-tax, tax, and total using a single tax rate.

How to use it

Enter amount and tax rate, choose add-tax or remove-tax mode if available.

Formula

Total = Pre-tax × (1 + rate); Pre-tax = Total ÷ (1 + rate).

Example

$100 + 8.25% tax → $108.25 total.

FAQs

Does this handle VAT/GST?

Mathematically similar for single-rate models; real invoices may have multiple rates.

Tax-inclusive vs exclusive?

Clarify whether your input price includes tax before interpreting results.

Rounding on cash registers?

Cent rounding rules vary; this tool uses full precision.
