Checking Whether Interest Income Is Already Included in EBIT

Summary

The document addresses how to calculate earnings before tax in a financing model when a company earns interest on cash. It asks whether interest income should be added to EBIT alongside the subtraction of interest expense. The answer cautions that interest income may already have been included in EBIT as non-operating income, so the model’s definition and presentation of EBIT should be checked before adding it separately.

The practical lesson is to inspect the source financial statements or model conventions and avoid counting the same income twice. The response is brief and does not establish a universal accounting presentation: classifications can depend on the reporting context and how the model defines operating profit. It offers no numerical example, accounting standard reference, or broader treatment of tax calculations, so it serves as a reminder to reconcile line items rather than a complete guide to building an income statement.

Key ideas

  • Interest income may already be included in the EBIT figure used by a model.
  • Check how EBIT is defined before adding interest income separately.
  • Adding an item twice would overstate earnings before tax.
  • The appropriate treatment depends on the financial statement or model presentation.

# Is interest income added to EBIT to calculate EBT?


# Is interest income added to EBIT to calculate EBT?












I am preparing a financing model and in the template the EBT calculation is: EBT=EBIT - Interest Expense.

However, I wonder if interest income (from keeping the money on the bank) should be added, i.e. EBT=EBIT + Interest Income - Interest Expense?

Many thanks for your explanation!

I think interest income should have already been included in EBIT as non operating income. You might want to check that before you add it.
