Description
Add the specific unit tax to price and multiply tax by quantity for totalTax.
An economic model term depends on the chosen price basis, quantities, reference period, and behavioral assumptions. A supplied arithmetic component does not establish a causal economic effect or a complete model equilibrium.
Add the specific unit tax to price and multiply tax by quantity for totalTax.
When to use this tool
Use Specific Tax Per Unit Wedge when you need one explicitly defined economic accounting or model component.
How to use the tool and how it works
- Enter preTaxUnitPrice, taxPerUnit, quantity. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read postTaxUnitPrice, totalTax. Use the output convention below.
Require nonnegative preTaxUnitPrice, taxPerUnit, and quantity. Add the specific unit tax to price and multiply tax by quantity for totalTax.1

}Limitations and assumptions
- This assumes full arithmetic addition to the supplied price; economic incidence, jurisdictional liability, exemptions, and monetary rounding are not determined.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
