What Is the Sales Tax Calculator?
A sales tax calculator helps you figure out the total cost including tax, or backwards. What the pre-tax price was from a total. Essential for budgeting purchases and business expense tracking.
The Formula
Total = Price x (1 + Tax Rate). Pre-tax Price = Total / (1 + Tax Rate).
Example
A $50 purchase at 8.25% sales tax totals $54.13, with $4.13 going to tax. For a $2,000 laptop in a 10% tax region like Seattle, expect $200 in tax for a $2,200 total. Removing tax from $108.25 reveals a $100 pre-tax price.
Common Uses
Shopping budgeting, business expenses, freelance invoicing, price comparison.
