- State Sales Tax: Purchase Price × Missouri State Tax Rate (4.225%)
- Local Sales Tax: Purchase Price × (Additional Local Tax Rate / 100)
- Total Sales Tax: State Sales Tax + Local Sales Tax
- Total Price: Purchase Price + Total Sales Tax
Where:
- Purchase Price: The cost of the item before tax.
- Missouri State Tax Rate: Fixed at 4.225% (0.04225).
- Additional Local Tax Rate: An optional percentage entered by the user for city, county, or district taxes.
