Sales Tax Calculator — Free Online Tool
About Sales Tax & VAT Calculator
Our Sales Tax & VAT Calculator is a streamlined financial utility designed for small business owners, freelancers, and global shoppers. Calculating the 'hidden' costs of sales tax or Value Added Tax (VAT) is essential for accurate budgeting and transparent invoicing. This tool provides a dual-mode interface that allows you to calculate both the tax amount added to a net price and the 'reverse tax' embedded within a gross total, providing total clarity on every transaction.
By using our high-precision decimal logic, you ensure that your financial calculations are accurate to the cent, preventing rounding errors in your bookkeeping.
Financial Calculation Features
- Net & Gross Modes: Easily toggle between adding tax to a price and extracting the tax portion from an inclusive total.
- Universal Rate Support: Enter any custom percentage to match local state sales tax or international VAT standards (e.g., 20% in the UK).
- Detailed Breakdown: See the raw tax amount separated from the total price for easier line-item reporting.
How to Calculate Tax
- Enter the amount you wish to process in the 'Original Price' field.
- Input your local tax rate as a percentage (e.g., 7.25 or 20).
- Switch between 'Add Tax' or 'Remove Tax' to see your final financial breakdown.
Pro Tip
If you're a freelancer in the UK or EU, use the 'Remove Tax' mode to quickly find your net earnings from a VAT-inclusive payment received from a client.
