What it means
Operating profit, or EBIT, tells you what the trading business produced before financing costs and tax. Net income tells you what is left for shareholders after both.
EBIAT sits deliberately between the two by removing tax but leaving interest in place. That middle position is useful because financing choices are decisions, not facts about the underlying business.
Two companies with identical operations can report very different net income simply because one carries debt and one does not. The measure is closely related to net operating profit after tax, or NOPAT, which is the term used in valuation and economic profit work.
The two are calculated the same way in most practical settings, and the difference is largely one of vocabulary between financial analysts and corporate finance teams. Calculation comes in two flavours.
The simple version applies the statutory or effective tax rate to EBIT, while the more careful version adds the actual tax charge back to net income along with interest, which captures the real tax position including credits and losses carried forward. EBIAT is most useful in three places.
It helps when comparing competitors with different debt levels, when valuing a business using free cash flow to the firm, and when assessing acquisition targets whose capital structure will change on completion anyway. Its main limitation is that it stops short of cash.
EBIAT still includes depreciation and amortisation and ignores working capital swings and capital spending, so a company can show a healthy EBIAT while consuming cash, which is why analysts pair it with a cash flow measure rather than relying on it alone.
In practice
Real-world examples.
Example
An analyst compares two regional bakeries. One is debt free and one carries $8,000,000 of borrowings, so their net income figures look very different, but their EBIAT figures are within 4% of each other and reveal near-identical operating performance.
Example
A private equity buyer values a target on EBIAT because it intends to repay the seller's debt at completion and refinance on entirely different terms. The seller's existing interest cost is irrelevant to what the business is worth to the buyer.
Example
A group finance team sets divisional bonuses on EBIAT rather than net profit, because divisions do not choose the group's borrowing and should not be rewarded or punished for treasury decisions made above them.
Formula
Calculation
EBIAT = EBIT x (1 - Tax rate)
A manufacturer reports the following for the year:
Revenue: $20,000,000
Operating expenses including depreciation: $16,000,000
EBIT = $20,000,000 - $16,000,000 = $4,000,000.
Interest expense on borrowings: $600,000
Pre-tax income = $4,000,000 - $600,000 = $3,400,000.
Tax at 25% = $3,400,000 x 25% = $850,000.
Net income = $3,400,000 - $850,000 = $2,550,000.
EBIAT = $4,000,000 x (1 - 0.25) = $3,000,000.
The cross-check works from the bottom up: net income of $2,550,000 plus after-tax interest of $600,000 x (1 - 0.25) = $450,000 gives $2,550,000 + $450,000 = $3,000,000, matching the EBIAT figure exactly.Case study
Seen in the real world.
Talgarth Coatings is an entirely fictional speciality chemicals group used here as an illustrative case. Its two divisions, one funded largely by an old acquisition loan and one funded from retained profit, had been measured on net profit for years, and the loan-funded division always looked like the weaker performer.
The chief financial officer rebuilt the divisional reports on an EBIAT basis. The loan-funded division turned out to be generating $3,000,000 of EBIAT on $20,000,000 of revenue, a materially better operating margin than its sibling, with all of the apparent gap explained by a $600,000 interest charge it had never controlled.
Talgarth changed both its internal reporting and its bonus scheme, keeping interest cost visible at group level where the decisions were actually made. In this illustrative example the numbers themselves never changed; what changed was which manager was being held responsible for which part of them.
Watch out
Common mistakes.
- Treating EBIAT as a cash figure. It still contains depreciation and amortisation and ignores capital spending and working capital movements, so it is a profit measure and not a cash measure.
- Applying the headline statutory tax rate when the company's effective rate is materially different because of credits, losses carried forward or overseas operations.
- Comparing one company's EBIAT with another's net income, which quietly reintroduces exactly the financing distortion EBIAT was designed to remove.
Questions
People also ask.
How does EBIAT differ from EBIT?
EBIT is operating profit before both tax and interest, whereas EBIAT deducts tax from that figure while still leaving interest undeducted.
Is EBIAT the same as NOPAT?
In practice yes for most purposes, since net operating profit after tax is calculated the same way, and the difference is mainly one of professional vocabulary.
Why leave interest in but take tax out?
Because the point is to show the after-tax return available to all funders of the business, and stripping out tax while ignoring the financing mix makes companies with different debt levels genuinely comparable.
