Sales tax is a consumption tax imposed by state and local governments on the sale of goods and services. Understanding how sales tax affects the final price of your purchases is essential for budgeting, shopping, and financial planning. Our Sales Tax Calculator helps you compute any one of three values when you know the other two: the before-tax price, sales tax rate, or after-tax price.
Accurate Budgeting: When shopping, especially for big-ticket items, knowing the exact final price including tax helps you budget accurately. Our calculator lets you determine the total cost before making a purchase.
Price Comparison: Compare prices across different tax jurisdictions. If you're shopping in different states or localities, sales tax rates vary, and our calculator helps you compare the true final prices.
Business Planning: Business owners need to calculate sales tax for pricing, invoicing, and accounting. Our calculator ensures accurate tax calculations for your products and services.
Understanding Tax Rates: When you see a final price, you can work backwards to determine the tax rate applied, helping you understand local tax structures.
Refund Calculations: If you're eligible for a tax refund or making a return, understanding the breakdown helps ensure you receive the correct amount.

Before Tax Price: This is the original price before sales tax is applied. This is what retailers typically advertise as the "price."
Tax Rate: The percentage rate of sales tax applied. In the U.S., sales tax rates vary by state (0% to 7.5%) and can include local taxes, making total rates range from 0% to over 10% in some areas.
After Tax Price: The final price you pay, including sales tax. This is the total amount that will be charged to your payment method.
Tax Amount: The dollar amount of sales tax added to your purchase. This is calculated as the difference between the after-tax and before-tax prices.
State Sales Tax: Most states have a base sales tax rate ranging from 2.9% to 7.5%. Five states (Alaska, Delaware, Montana, New Hampshire, and Oregon) have no state sales tax.
Local Sales Tax: Many cities and counties add their own sales tax on top of the state rate. Combined rates can exceed 10% in some areas.
Special Tax Rates: Some items may have different tax rates (e.g., food, clothing, prescription drugs) depending on state and local laws.
Online Sales Tax: Following the Supreme Court's Wayfair decision, online retailers may collect sales tax based on your shipping address, making tax rates location-dependent.
Shopping for Big Purchases: When buying a car, furniture, or electronics, sales tax can add hundreds or thousands of dollars. Calculate the final price before making your decision.
Cross-Border Shopping: If you're shopping across state lines, different tax rates can significantly affect prices. Use the calculator to compare true costs.
Budget Planning: When planning purchases, calculate the after-tax price to ensure you have enough funds. A $1,000 item with 8% tax becomes $1,080.
Business Pricing: Set prices that account for sales tax, or calculate tax-inclusive pricing for customers. Ensure your pricing covers all costs including taxes.
Invoice Verification: Verify that invoices show correct sales tax calculations. The calculator helps you double-check vendor invoices.
Plan for Tax: Always account for sales tax in your budget. Even a 5% rate adds $50 to every $1,000 spent.
Compare Locations: If you have flexibility in where you make purchases, compare final prices including tax across different locations.
Understand Local Rates: Research your local sales tax rate for accurate calculations. Rates can vary by city, county, and state.
Keep Receipts: Save receipts that show tax breakdowns for tax-deductible business expenses or when itemizing deductions.
Online Purchases: Remember that online purchases may include sales tax based on your shipping address, not necessarily where the retailer is located.
Forgetting Tax: Don't forget to include sales tax when budgeting. The listed price is rarely what you'll actually pay.
Assuming Rates: Don't assume all purchases have the same tax rate. Different items may have different rates, and rates vary by location.
Rounding Errors: Our calculator handles rounding properly, but manual calculations can introduce errors. Always use a calculator for accuracy.
Not Accounting for Local Tax: Remember that local taxes are added to state taxes. The total rate is what matters for your final price.
Whether you're shopping, budgeting, or running a business, understanding sales tax is crucial for accurate financial planning. Use our Sales Tax Calculator to determine before-tax prices, tax rates, or final prices with confidence. Make informed purchasing decisions and budget accurately with precise sales tax calculations.
