How the decalculator works

The Excel de-calculator works by using a formula that takes the following steps:

Step 1: take the total price and multiply it by one minus the tax rate

Step 2: multiply the result from step one by the tax rate to get the dollars of tax

Step 3: subtract the dollars of tax from step 2 from the total price
