from the initial 24% Sales tax or VAT
to the new 20% tax included value

Tax free value = 58.87
Initial tax, extracted (24%) = 14.13
New tax included value = 70.65 (- 2.35 vs. initial)
New tax, added (20%) = 11.77

Detailed calculations below:

Detailed answer:

Initial tax included value =


73 =


Tax free value + 24% × Tax free value =


(1 + 24%) × Tax free value


Tax free value =


73 ÷ (1 + 24%) =


73 ÷ (100% + 24%) =


73 ÷ 124% =


73 ÷ 1.24 ≈


58.870967741935 ≈


58.87


Initial tax, extracted =


73 - 58.870967741935 =


14.129032258065 ≈


14.13


New tax included value =


Tax free value + 20% × Tax free value =


Tax free value × (1 + 20%) =


58.870967741935 × (1 + 20%) =


58.870967741935 × (100% + 20%) =


58.870967741935 × 120% =


58.870967741935 × 1.2 =


70.645161290322 ≈


70.65


New tax, added =


70.645161290322 - 58.870967741935 =


11.774193548387 ≈


11.77

Recalculate value with a different new Sales tax or VAT

Tax inclusive value = Tax free value × (1 + Tax%)

Tax free value = Tax inclusive value ÷ (1 + Tax%)

All the prices recalculated with new Sales taxes or VATs

Having an initial full tax included price purchase, how to recalculate it to a new different tax included value (Sales tax or VAT)?

Step 1: Calculate the Tax free value out of the Full initial tax inclusive value

  • Full initial tax included value = Tax free value + Tax value
  • Tax value = Tax% × Tax free value
  • Full initial tax included value = Tax free value + Tax% × Tax free value = (1 + Tax%) × Tax free value
  • Full initial tax included value = (1 + Tax%) × Tax free value

    In conclusion:

    Tax free value = Full initial tax included value ÷ (1 + Existent tax%) =

Step 2: Add the new tax value to the Tax free value

  • Full new tax included value = Tax free value + New tax value
  • New tax value = New tax% × Tax free value
  • Full new tax included value = Tax free value + New tax% × Tax free value = (1 + New tax%) × Tax free value
  • In conclusion, Full new tax included value = (1 + New tax%) × Tax free value = (1 + New tax%) × Full initial tax included value ÷ (1 + Existent tax%) = (1 + New tax%)/(1 + Existent tax%) × Full initial tax included value

    Full new tax included value = (1 + New tax%)/(1 + Existent tax%) × Full initial tax included value

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

  • Case 1: Existent tax = 20%, New tax = 19%

    Step 1, 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, Add the new tax value:
    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
    Answer: New tax included value = (1.19 ÷ 1.2) × Initial tax included value
  • Case 2: Existent tax = 20%, New tax = 5%

    Step 1, 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, Add the new tax value:
    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
    Answer: New tax included value = (1.05 ÷ 1.2) × Initial tax included value.
