Sales Tax Calculator: Quickly Calculate Tax on Your Purchases
The Sales Tax Calculator is a simple yet powerful tool that helps consumers and businesses determine the final price of an item or service after applying a specific sales tax rate. It is especially useful for budgeting, price comparison, invoicing, and understanding how taxes impact your total expenses.
What Is Sales Tax?
Sales tax is a government-imposed charge applied to the sale of goods and services. It's collected at the point of purchase and typically calculated as a percentage of the item's selling price. Sales tax rates vary based on location (country, state, county, and city), product category, and applicable exemptions.
Why Use a Sales Tax Calculator?
Whether you're a shopper or a business owner, a sales tax calculator helps you:
- Determine the total cost of a product or service including tax
- Calculate the amount of sales tax being charged
- Break down prices for receipts or invoices
- Adjust base prices to include or exclude tax
- Make informed decisions when comparing items across regions
Sales Tax Calculator Formula
There are two main calculations involved when working with sales tax:
1. Calculating Total Price with Tax
Total Price = Item Price + (Item Price × Sales Tax Rate)
2. Extracting Sales Tax from Total Price
Sales Tax = Total Price × [Tax Rate ÷ (1 + Tax Rate)]
Key Inputs
- Item Price (Pre-Tax): The cost of the item before tax is applied
- Sales Tax Rate: The applicable tax percentage (e.g., 6.5%, 9.75%)
- Mode: Choose between "Add Tax to Price" or "Extract Tax from Total"
Key Outputs
- Sales Tax Amount: The calculated amount of tax on the purchase
- Total Price: The final amount after including tax
Example 1: Add Tax to a Price
- Item Price: $100
- Sales Tax Rate: 8%
Sales Tax = $100 × 0.08 = $8
Total Price = $100 + $8 = $108
Example 2: Extract Tax from a Total Price
- Total Price (with Tax): $108
- Sales Tax Rate: 8%
Sales Tax = $108 × [0.08 ÷ 1.08] = $8
Item Price (Before Tax) = $108 - $8 = $100
