Instructions:
- Identify the year to date & 20-year average annual historical inflation rates for your company using the tables shown below the calculator
- Enter the following values into the blue-colored cells:
- Prior year end inventory balance at cost
- Current year inflation rate
- 20-year average annual inflation rate: used to calculate the 20-year projected tax savings
- Combined federal & state tax rate
- The green-colored cells will automatically update as soon as all values have been entered into the blue-colored input cells
Note: LIFO is adopted on a prospective basis & LIFO tax savings accrue beginning in the year of the change. Prior period benefits can NOT be retrospectively recaptured. 20-year cumulative taxable income reduction & after-tax cash savings shown in calculator are for analysis purposes only & is provided to project the potential tax savings from LIFO that could occur over the next 20 years based on your current year inventory balance at cost & the historical inflation rates.
