Sales Tax Calculator Examples
The Sales Tax Calculator computes sales tax amounts and final prices for US states and international VAT. Below are practical examples for shoppers, retailers, and accountants.
Basic Sales Tax Calculation

Location: California (Los Angeles)
Pre-tax price: $100.00
Tax rates:
State rate: 6.00%
County rate: 0.25%
City rate: 2.25%
Combined: 8.50%
Tax amount: $8.50
Total price: $108.50
Sales Tax Rates by State
Combined state + average local rates for major states:
State State Rate Avg Local Combined
California 6.00% 1.43% 7.43%
Texas 6.25% 1.94% 8.19%
New York 4.00% 4.52% 8.52%

Reverse Calculation — Find Pre-Tax Price
You paid $108.50 total. What was the pre-tax price?
Total paid: $108.50
Tax rate: 8.50%
Pre-tax price = $108.50 / (1 + 0.085) = $100.00
Tax amount = $108.50 - $100.00 = $8.50
Useful for accounting when you know the final price
and need to separate the tax component.

VAT Calculation — Exclusive (Tax Added)

Country: United Kingdom
VAT rate: 20% (standard)
Pre-VAT price: £100.00
VAT amount: £20.00
Total (inc. VAT): £120.00
VAT Calculation — Inclusive (Tax Included)
Extract VAT from a price that already includes it:
Price including VAT: £120.00
VAT rate: 20%
Pre-VAT price = £120.00 / 1.20 = £100.00
VAT amount = £120.00 - £100.00 = £20.00
Used when a price is quoted inclusive of VAT and you
need to separate the net amount for accounting.
