Sales Tax Calculator

About Sales Tax Calculator

Sales tax changes the final price of what you buy and sell. Enter an amount and tax rate and choose whether to add tax to a price or remove it from a total. The tool shows the tax and the new amount. Shoppers use it to estimate costs, and sellers use it to split tax from a total. Rates differ by state and city, so use the rate that applies to you.

Example

Input: $100 at 7% adding tax. Output: tax of $7 and a total of $107. In remove mode, $107 gives a $100 base and $7 of tax.

Tips for better results

• Look up your local combined rate. State, county and city taxes can stack.
• Some items are exempt in some places.
• Keep records if you run a business.

When to use Sales Tax Calculator

Use this calculator when you want to know the final price of something before you buy it, or when you need to separate the tax from a total that already includes it. Shoppers, small sellers, freelancers and bookkeepers can switch between adding and removing tax with a single rate. Check the rate that applies to your location and product, since it can differ by place and item, and keep in mind this tool is for estimates.

Real-world uses

• A shopper wants to know the checkout price of a laptop before driving to the store, using their local combined rate.
• A market vendor takes a tax-inclusive total from a customer and wants to know how much of it was tax.
• A freelancer who sells printed goods checks what price to display so the tax-inclusive amount lands on a round figure.
• A bookkeeper reviewing receipts removes tax from several totals to compare pre-tax costs across suppliers.

Common mistakes to avoid

• Using the state rate alone can understate the total in places with local taxes, so check the combined rate for the exact location.
• Entering a total that already includes tax in the add mode inflates the number, so choose the mode that matches the amount you have.
• Assuming every item is taxed the same way ignores exemptions, so check whether your product or service has special treatment where you sell.
