How to Calculate Sales Tax and List Price from Total Amount and Tax Rate
- Find the total price and tax percentage
- Divide tax percentage by 100 to get tax rate as a decimal
- Add 1 to the tax rate to get your division factor
- Divide the total price by the division factor to get the list price
- Multiply list price by decimal tax rate to get tax amount
For example, say you purchased a new phone and your total credit card charge was $858. What was the list price? What was the amount of tax you paid? Your state sales tax rate is 7.25%.
- The total price is $858 and tax percentage is 7.25%
- Divide tax percentage by 100: 7.25 / 100 = 0.0725
- Add 1 to the tax rate: 1.0725
- Divide the total price by the division factor: $858/1.0725 = $800
- Multiply list price by decimal tax rate: $800 * 0.0725 = $58
The list price was $800 and the amount of tax you paid was $58.
