To add tax to a price, multiply the price by 1 plus the tax rate in decimal form. Governments charge taxes to generate revenue for public services and infrastructure.
How to Calculate Sales Tax
- Convert the percentage rate to a decimal by moving the decimal point two places left.
- Multiply the item cost by the decimal rate to find the sales tax amount.
- Add this amount to the item cost to calculate the total price.
For example, 6% sales tax on a $100 item is calculated as follows: convert 6% to 0.06, then 0.06 x $100 = $6 sales tax, and finally $100 + $6 = $106 total price.
Pricing Strategy and Tax Considerations
When setting prices, consider offering discounts or using psychological pricing tactics to help maximize profit while remaining transparent about tax costs. Check with state and local authorities on expected sales tax rates and surcharges and follow local laws on rounding tax amounts up or down. Also, consider whether to display prices with tax included or exclusive, based on customer expectations.
