How Global Tax Calculations Work

Whether you are a freelancer in the UK calculating VAT, a business owner in India filing GST, or a shopper in the USA estimating Sales Tax, the underlying mathematics is universal.

This tool helps you switch between adding tax to a base price (Exclusive) and extracting the tax component from a final price (Inclusive) with a single click.

The Tax Formulas

Adding Tax (Exclusive)

Total = Base × (1 + Rate%)

Removing Tax (Inclusive)

Tax = Total - [Total ÷ (1 + Rate%)]

For Business Owners

Use the 'Exclusive' mode to generate invoices. Add your base service cost and the applicable tax rate to find the final bill amount.

For Shoppers & Buyers

Use the 'Inclusive' mode to find the real cost of a product. If an item costs $110 (inc. tax), find out how much is the actual product value.

Frequently Asked Questions

What is the difference between Exclusive and Inclusive Tax?

Exclusive Tax means tax is added ON TOP of the price (e.g., $100 + 10% Tax = $110). Inclusive Tax means the price ALREADY contains the tax (e.g., $110 includes the $10 tax component).

Can I use this for VAT (Europe/UK)?

Yes. VAT (Value Added Tax) works exactly like GST mathematically. Simply enter your country's VAT rate (e.g., 20% for UK, 19% for Germany) to get the correct amounts.

How do I calculate Reverse GST/VAT?

Select the 'Remove Tax (Inclusive)' option in the calculator. The formula used is: Tax Amount = Total Price - [Total Price / (1 + (Tax Rate / 100))].

Does this work for US Sales Tax?

Yes. Simply enter your state's Sales Tax rate (e.g., 8.25% for Texas, 7.25% for California) to calculate the final price of any item or service.
