Formula basis

Fixed tax = liters × entered rate (−1 selects the code’s JPY 28.7/L default); petroleum-related tax = liters × JPY 2.8; consumption tax = retail total × rate ÷ (1 + rate).

Calculation method

This calculator splits a tax-inclusive gasoline retail price into the entered fixed levy, JPY 2.8 per liter petroleum-related tax, and tax-inclusive consumption tax.

Exclusions and checks required

  • The possible error in the implementation comment’s abolition date is not resolved here; this content describes only the values the calculator actually uses.
  • Subsidies, distribution margins, regional pricing, and the precise legal layering of petroleum taxes are not reconstructed.
