Sales Tax, VAT & Reverse Tax Calculation Formulas

Last reviewed: September 2026

Calculation Formula

Add Tax: Gross = Net × (1 + Rate / 100) | Extract Tax: Net = Gross / (1 + Rate / 100)

Variables & Definitions

Net Price:: Original baseline cost of the product or service before tax is applied
Tax Rate (%):: Combined statutory sales tax, VAT, or GST percentage rate
Tax Amount:: Net Price × (Tax Rate / 100) in forward mode, or Gross - Net in reverse mode
Gross Price:: Total final retail price paid at checkout including all applicable taxes

Core Assumptions

A single combined tax rate applies uniformly across the entire subtotal.
Items are fully taxable under standard local revenue codes without special excise duties.
Final currency amounts are rounded to the nearest cent or standard fiscal decimal unit.

Disclaimer: Tax regulations vary across jurisdictions, counties, states, and nations. Certain necessities such as unprepared grocery foods, prescription medicines, and educational supplies may qualify for exemptions or reduced tax rates. Consult your local tax authority, IRS, HMRC, or a licensed tax advisor for statutory business compliance.

Worked Example: Adding 8.25% Sales Tax vs. Reversing 20% VAT

A consumer in California buys equipment quoted at $250.00 net, while a contractor in the UK receives a tax-inclusive business invoice for £600.00 that includes 20% standard VAT:

Scenario 1 (US Net → Gross)	$250.00 Net × 8.25% Tax Rate = $20.63 Tax \| Final Checkout Total = $270.63
Scenario 2 (UK Gross → Net)	£600.00 Gross ÷ (1 + 0.20) = £500.00 Pre-Tax Net \| Extracted VAT = £100.00

💡 Notice that simply subtracting 20% from £600 would yield £480 (a £20 calculation error). Dividing by 1.20 correctly identifies that £100 represents exactly 20% of the £500 baseline net price.

Frequently asked questions

What is the difference between Sales Tax, VAT, and GST?

Sales Tax (used primarily in the United States) is a single-stage tax assessed only at the final point of retail purchase. Value Added Tax (VAT, used in the EU, UK, and 160+ countries) is an incremental multi-stage consumption tax collected at each production stage based on the value added. Goods and Services Tax (GST, used in Canada, Australia, Singapore, and New Zealand) operates similarly to a comprehensive single-rate VAT.

Why can’t I just subtract 20% from a price to remove 20% VAT?

Because the original 20% tax was calculated on top of a smaller base amount. Subtracting 20% directly from the larger gross total removes too much money. To properly extract a 20% tax, divide the gross total by 1.20 (or 1 + Tax Rate / 100). For example, £120 ÷ 1.20 = £100 net, with £20 tax.

What is the formula to calculate sales tax manually?

To calculate sales tax manually: Tax Amount = Net Price × (Tax Rate ÷ 100), and Total Checkout Cost = Net Price + Tax Amount. For example, on a $50 purchase at an 8% sales tax rate: $50 × 0.08 = $4.00 sales tax, giving a total of $54.00.

How do I calculate 8.875% NYC sales tax on a $200 purchase?

Enter $200 as the price and 8.875 as the tax rate in "Add Tax" mode. The calculator computes $17.75 in sales tax, resulting in a final checkout total of $217.75.

Are essential groceries and prescription medications subject to sales tax?

In most US states and international tax jurisdictions, essential necessities like unprepared grocery food items, prescription medications, and certain medical devices are either fully exempt (0% tax) or taxed at a special reduced rate.
