How to use Sales Tax Calculator

It is handy for shoppers, freelancers issuing invoices, and anyone reconciling receipts.

Adding tax versus extracting tax
To add tax, multiply the net price by (1 + rate). To extract tax from a gross, tax-inclusive total, divide by (1 + rate) to recover the net amount and subtract to find the tax. Mixing these up is a common invoicing error — always be clear whether a quoted price already includes tax.
Sales tax, VAT and GST
Different regions use different consumption taxes: US sales tax is added at the point of sale and varies by state and locality; VAT (Europe) and GST (Australia, Canada, India and others) are typically built into displayed prices. Rates and rules differ widely, so use the correct rate for the jurisdiction and check whether your prices should be shown inclusive or exclusive of tax.
