Sales tax is calculated by multiplying the purchase price by the sales tax rate.
Sales Tax Amount = Price × (Tax Rate / 100)
Total Amount = Price + Sales Tax AmountExample
If you are buying an item for $50 and the sales tax rate is 7.5%:
- Tax Amount = $50 × 0.075 = $3.75
- Total Amount = $50 + $3.75 = $53.75
