How to Use This Tool

This calculator updates in real-time as you type. Here is how to get your exact tax breakdown:

1. Choose your calculation type:

• Add VAT (I have the Net amount): Use this if you know your base rate (e.g., $1,000) and need to figure out how much tax to add on top for your client’s invoice.
• Remove VAT (I have the Gross total): Use this if you agreed to a flat fee (e.g., $1,000 total) and need to extract the exact tax amount for your tax filings, leaving you with the true net revenue.

2. Enter the Amount: Input the monetary value you are working with. The calculator works with any global currency.

3. Enter the Tax Rate: Input the specific tax percentage for your region or your client’s region (e.g., 20 for UK VAT, 5 for Canadian GST, or 16 for Kenyan VAT).

4. Copy your numbers: The Results Panel instantly provides your Net Amount, Tax Amount, and Gross Total. Copy these directly onto your invoice or into your accounting software.

Next step: Get paid. Now that you have your exact tax figures, drop them directly into our Free Invoice Generator. Create a professional, secure PDF invoice for your client in seconds—no sign-up required.
