Value Added Tax, VAT: Recalculate Gross Amounts and Prices (With Tax Included), From Original VAT Rates to New Ones. Calculate Net Amounts (Without Tax), the New Gross Amounts and the Values of VAT Tax
Recalculate Gross Amount (Tax Included) with a New VAT Rate
Gross Amount = Net Value × (1 + Tax%)
Net Amount = Gross Amount ÷ (1 + Tax%)
The Latest Gross Amounts Recalculated With New VAT Rates
Calculate the Gross Amount (With Tax Included) With Different, New, VAT Rates
Step 1: Calculate the Net Amount (Without Tax)
- Initial Gross Amount = Net Amount + Initial Tax Amount
- Initial Tax Amount = Initial Tax% × Net Amount
- Initial Gross Amount = Net Amount + Initial Tax% × Net Amount = (1 + Initial Tax%) × Net Amount
Initial Gross Amount = (1 + Initial Tax%) × Net Amount
In conclusion: Net Amount = Initial Gross Amount ÷ (1 + Initial Tax%) =
Step 2: Add the New Tax Amount to the Net Amount
- New Gross Amount = Net Amount + New Tax Amount
- New Tax Amount = New Tax% × Net Amount
- New Gross Amount = Net Amount + New Tax% × Net Amount = (1 + New Tax%) × Net Amount
- In conclusion, New Gross Amount = (1 + New Tax%) × Net Amount = (1 + New Tax%) × Initial Gross Amount ÷ (1 + Initial Tax%) = (1 + New Tax%)/(1 + Initial Tax%) × Initial Gross Amount
New Gross Amount = (1 + New Tax%)/(1 + Initial Tax%) × Initial Gross Amount
Examples of calculations:
- Case 1: Initial Tax Rate = 20%, New Tax Rate = 19%
Step 1, Calculate Net Amount:
(1 + Initial Tax%) = 1 + 20% = 100/100 + 20/100 = 120/100 = 1.2 => Initial Gross Amount = 1.2 × Net Amount, and Net Amount = Initial Gross Amount ÷ 1.2
Step 2, Add the New Tax Amount:
New Gross Amount = (1 + New Tax%) × Net Amount = (1 + 19%) × Net Amount = (100/100 + 19/100) × Net Amount = 119/100 × Net Amount = 1.19 × Net Amount = 1.19 × Initial Gross Amount ÷ 1.2 = 1.19/1.2 × Initial Gross Amount
Answer: New Gross Amount = (1.19 ÷ 1.2) × Initial Gross Amount - Case 2: Initial Tax Rate = 20%, New Tax Rate = 5%
Step 1, Calculate Net Amount:
(1 + Initial Tax%) = 1 + 20% = 100/100 + 20/100 = 120/100 = 1.2 => Initial Gross Amount = 1.2 × Net Amount, and Net Amount = Initial Gross Amount ÷ 1.2
Step 2, Add the New Tax Amount:
New Gross Amount = (1 + New Tax%) × Net Amount = (1 + 5%) × Net Amount = (100/100 + 5/100) × Net Amount = 105/100 × Net Amount = 1.05 × Net Amount = 1.05 × Initial Gross Amount ÷ 1.2 = 1.05/1.2 × Initial Gross Amount
Answer: New Gross Amount = (1.05 ÷ 1.2) × Initial Gross Amount.
