Sales Tax & VAT Calculator

Add or extract sales tax and VAT from transaction amounts.

Overview

Computes state, county, and municipal sales taxes and Value Added Tax (VAT) on retail merchandise purchases.

Formula & Calculation Method

Sales Tax Amount = Net Price × (Tax Rate / 100) | Total Amount = Net Price + Sales Tax Amount

Calculates combined composite state and local sales tax rates across US, European VAT, and international retail jurisdictions.

Worked Example: $250 Electronics Purchase with Combined 8.25% Sales Tax

Inputs: Net Retail Price = $250.00 | Combined Tax Rate = 8.25%

  • Sales tax calculation = $250.00 × 0.0825 = $20.63
  • Total customer checkout price = $250.00 + $20.63 = $270.63

Summary: Retail Price = $250.00 | Sales Tax (8.25%) = $20.63 | Total Due = $270.63
