Handle Tax on Every Invoice With Confidence
Two Tasks, One Simple Calculator
Working with tax usually comes down to two operations: adding tax to a net price so an invoice shows the correct gross, and removing tax from a price to find the net underneath. Add tax mode covers the first; remove tax mode covers the second. This calculator does both accurately in your browser.
Add Tax for Cleaner Invoices
When you quote a net price and need the amount to charge, add mode applies your tax rate to the net, splits out the tax line and gives you the gross total for the invoice. The breakdown makes your bill transparent and easy to reconcile.
Remove Tax to See the Real Net
When you receive a price or a payment that already includes tax, remove mode backs out the net amount in one step. This is essential for recording income net of VAT or sales tax, comparing suppliers who quote inclusive of different rates, or working out the tax you need to report.
How to Use This Calculator
Choose whether you are adding or removing tax, enter the amount and your local tax rate—or tap a common rate preset. The net, tax and gross amounts update live, with the key figure (gross when adding, net when removing) highlighted. Copy the result for your records. Always confirm the applicable rate with your jurisdiction.
