Having an initial given tax included value, how to calculate a new different tax included value?

Step 1: Extract existent included tax value from the initial tax included value, calculate tax free value

  • Initial tax included value = Tax free value + Existent tax value
  • Existent tax value = Existent tax% * Tax free value
  • Initial tax included value = Tax free value + Existent tax% * Tax free value = (1 + Existent tax%) * Tax free value
  • Initial tax included value = (1 + Existent tax%) * Tax free value

    In conclusion:

    Tax free value = Initial tax included value / (1 + Existent tax%) =

Step 2: Adding the new tax value to the tax free value

  • New tax included value = Tax free value + New tax value
  • New tax value = New tax% * Tax free value
  • New tax included value = Tax free value + New tax% * Tax free value = (1 + New tax%) * Tax free value
  • In conclusion, New tax included value = (1 + New tax%) * Tax free value = (1 + New tax%) * Initial tax included value / (1 + Existent tax%) = ((1 + New tax%) / (1 + Existent tax%)) * Initial tax included value

    New tax included value = ((1 + New tax%) / (1 + Existent tax%)) * Initial tax included value

Examples of calculating a new tax included value from an initial tax included value:

  • Existent tax = 20%, New tax = 19%
    Step 1, extract the existent tax value from the initial tax included value, calculate tax free value:
    (1 + Existent tax%) = 1 + 20% = 100/100 + 20/100 = 120/100 = 1.2 => Initial tax included value = 1.2 * Tax free value, and Tax free value = Initial tax included value / 1.2
    Step 2, adding the new tax value to the tax free value calculated at step 1:
    New tax included value = (1 + New tax%) * Free tax value = (1 + 19%) * Tax free value = (100/100 + 19/100) * Tax free value = 119/100 * Tax free value = 1.19 * Tax free value = 1.19 * Initial tax included value / 1.2 = (1.19 / 1.2) * Initial tax included value
    Final result: New tax included value = (1.19 : 1.2) * Initial tax included value
  • Existent tax = 20%, New tax = 5%
    Step 1, extract the existent tax value from the tax included value, calculate tax free value:
    (1 + Existent tax%) = 1 + 20% = 100/100 + 20/100 = 120/100 = 1.2 => Initial tax included value = 1.2 * Tax free value, and Tax free value = Initial tax included value / 1.2
    Step 2, adding the new tax value to the tax free value calculated at step 1:
    New tax included value = (1 + New tax%) * Free tax value = (1 + 5%) * Tax free value = (100/100 + 5/100) * Tax free value = 105/100 * Tax free value = 1.05 * Tax free value = 1.05 * Initial tax included value / 1.2 = (1.05 / 1.2) * Initial tax included value
    Final result: New tax included value = (1.05 : 1.2) * Initial tax included value
