Implied multiple
Brainteasers & GuesstimatesThe multiple you get by dividing a value you have just calculated back by its earnings driver, used to test whether the answer is plausible.
Also written: implied multiple check, back out the multiple
An implied multiple runs the valuation backwards. Take the enterprise value you have produced, divide it by annual EBITDA, and ask whether a real transaction would clear at that number. The same trick works on equity value over earnings, or on a price per subscriber, per bed or per square metre.
It is the fastest check available in a case because it needs no new information and no second calculation of the same kind. You already have both numbers, and the ratio between them either sits in a range you recognise or it does not.
What makes it powerful is that it identifies that an answer is wrong before it identifies why. An enterprise value implying 2.0x EBITDA for a healthy business tells you something upstream has failed, whether that is a period error, a decimal, or a misread margin. You then go looking, rather than presenting the number and finding out from the interviewer.
The same check has a second use once a deal is on the table. Backing an implied multiple out of a DCF, or out of the exit value an LBO requires, is how you test whether a model is quietly assuming something the market would not pay for.
Worked example
A candidate values a business at €280m and is asked whether that is sensible. Annual EBITDA is €140m, so the answer implies 8.0x divided by four, which is 2.0x.
No healthy control business trades hands at 2.0x EBITDA, so the €280m is wrong. The cause turns out to be a quarterly EBITDA figure multiplied by a twelve month multiple.
The check took one division and no additional information.
