Frequently Asked Questions

What's the difference between adding and removing tax?

Adding tax calculates the final price when tax is applied to a base price (e.g., $100 + 10% tax = $110). Removing tax (reverse calculation) finds the base price from a tax-inclusive price (e.g., $110 with 10% tax = $100 base price).

Can I calculate VAT and GST with this calculator?

Yes! This calculator works for all types of consumption taxes including Sales Tax, VAT (Value Added Tax), and GST (Goods and Services Tax). Simply enter your tax rate and the calculator will compute the amounts.

How do I find the tax amount only?

Select the 'Tax Only' calculation type, enter the base amount and tax rate. The calculator will show just the tax amount without adding it to the base price. For example, 10% tax on $100 = $10 tax.
