- Make informed decisions: Compare prices across different tax jurisdictions
- Run businesses efficiently: Properly calculate taxes owed and maintain compliance
- Plan expenses: Account for taxes in financial planning and budgeting
- Understand receipts: Decipher what you're actually paying for

Calculation Scenarios
Example 1: Calculating After-Tax Price
You want to buy a laptop priced at $800 with a 7% sales tax rate. Enter $800 as the before tax price and 7% as the tax rate. The calculator will determine that the after-tax price is $856.
Example 2: Determining Tax Rate
You see a receipt showing a before-tax price of $50 and an after-tax price of $53.50. Enter these values to discover that the tax rate was 7%.
Example 3: Finding Before-Tax Price
You know the final price of an item is $107 including tax, and the tax rate is 7%. The calculator will determine that the before-tax price was $100.
Pro Tip: Understanding Tax-Exclusive vs Tax-Inclusive Pricing
In the United States, prices are typically displayed without sales tax (tax-exclusive), while in many other countries, prices include all taxes (tax-inclusive). Our calculator helps you work with both scenarios by allowing you to calculate any missing value.
Understanding Sales Tax Fundamentals
How Sales Tax Works
Sales tax is calculated by multiplying the before-tax price by the tax rate (expressed as a decimal):
Sales Tax Formula
Sales Tax Amount = Before Tax Price × (Tax Rate / 100)
After Tax Price = Before Tax Price + Sales Tax Amount
