The Reverse Tax Formula
When a price is Tax Inclusive, you cannot simply subtract the tax percentage from the total. You must use the reverse calculation formula to find the true base price:
Base Price =
Total Amount
1 + (Tax Rate / 100)
For your $1,000.00, the exclusive calculation ensures the13% share is accurately separated.
At a 13% rate, every $100 of base price equals$13 in tax, making the total$113.
