How do you calculate exclusive VAT/GST (adding tax to a net price)?

To add VAT/GST to a net amount, multiply the net price by the tax rate percentage (e.g., Net Amount x 0.15 for 15% VAT). Add the resulting tax to the net price to get the total gross price.

How do you calculate inclusive VAT/GST (extracting tax from a gross price)?

To extract embedded VAT/GST from a gross total, divide the gross amount by (1 + Tax Rate / 100) to find the net price. Subtracting the net price from the gross total reveals the exact tax portion.

How Value Added Tax (VAT) and Goods & Services Tax (GST) Function

Value Added Tax (VAT) and Goods and Services Tax (GST) are indirect consumption taxes levied on goods and services at each point in the supply chain where value is added. Millions of businesses, accountants, and e-commerce merchants navigate pricing using two operational paradigms:

Tax-Exclusive Pricing (B2B): Predominant in commercial transactions where businesses reclaim input tax credits. The advertised price represents the net amount, and VAT/GST is added separately to invoices.
Tax-Inclusive Pricing (B2C): Standard in consumer retail stores, restaurants, and consumer web shops. The shelf price already includes the statutory consumption tax.

Operational Formulas for Tax Calculations

Operation Type	Accounting Formula	Concrete Example ($100 @ 15%)
Add Tax (Exclusive)	`Tax = Net × (Rate / 100)` `Gross = Net + Tax`	$100 × 0.15 = $15.00 Tax Gross: $115.00
Remove Tax (Inclusive)	`Net = Gross / (1 + Rate / 100)` `Tax = Gross - Net`	$115 / 1.15 = $100.00 Net Tax: $15.00

Why You Cannot Multiply a Gross Price Directly by the Tax Percentage

A widespread bookkeeping error is attempting to extract VAT by multiplying the gross price directly by the tax rate (e.g., $115 × 15% = $17.25). This produces a mathematically incorrect tax figure because the 15% tax was originally assessed on the $100 net base, not the $115 total. To extract embedded tax correctly, you must divide by 1 + (Rate / 100).
