Sales Tax Calculator

This sales tax calculator helps you quickly determine tax amounts, total costs, and pre-tax prices for purchases across different locations. Simply enter the pre-tax price and tax rate to calculate the tax amount and final total, or use the reverse calculator to find the original price before tax when you know the total amount. The quick state rates feature allows you to instantly apply common tax rates from major states for accurate comparisons.

Understanding sales tax calculations is important for personal budgeting, business expense tracking, and tax planning across different jurisdictions. Sales tax rates vary significantly between states, counties, and cities, affecting your purchasing power and business costs. Use this calculator for shopping comparisons, business expense calculations, travel budgeting, and to understand how different tax rates impact your bottom line. The reverse calculator is particularly useful for determining original prices from receipts or when tax-inclusive pricing is displayed.
