About the WooCommerce Tax Calculator
The WooCommerce Tax Calculator splits a price into its net, tax, and gross parts using a single tax rate. Enter a price and a rate, then choose whether that price already includes tax. It is handy for store owners, freelancers, and bookkeepers who need to check a figure quickly, set a tax-inclusive list price, or work backward from a gross total. Everything runs in your browser, so nothing is uploaded.

Frequently asked questions
What does the tax-inclusive toggle do?
When set to 'Includes tax', the tool treats your entered price as the gross amount and works backward to find the net price and the tax inside it. When set to 'Excludes tax', it adds tax on top of your entered net price to get the gross.
How is the tax amount worked out?
For a tax-exclusive price, tax equals price times rate divided by 100. For a tax-inclusive price, net equals price divided by (1 plus rate divided by 100), and tax is the gross minus the net.
Does this match what WooCommerce charges at checkout?
It can differ. WooCommerce applies the tax rates, tax classes, location rules, and rounding settings you configure, including per-line versus per-cart rounding. Use this tool for a quick estimate, not as a replacement for your store's tax setup.
Is my data sent anywhere?
No. All calculations run in your browser. Nothing you enter is uploaded or logged.
Why might the rounded totals look off by a cent?
Each value is rounded to 2 decimals for display, so the shown net plus the shown tax can occasionally differ from the gross by one cent. This is normal rounding behavior and also occurs in real store systems.
