My post praising the value of investment bankers led to a number of e-mails asking for the parameters for investment banking fees for M&A. Here is the retail M&A price list from a first tier investment bank:

Aggregate value of transaction – Aggregate fee as a % of the transaction

$20 billion – 0.150%
$15 billion – 0.180%
$12.5 billion – 0.200%
$10 billion – 0.230%
$9 billion – 0.240%
$8 billion – 0.250%
$7.5 billion – 0.265%
$7 billion – 0.275%
$6 billion – 0.300%
$5 billion – 0.320%
$4 billion – 0.360%
$3 billion – 0.400%
$2 billion – 0.450%
$1 billion – 0.600%
$900 million – 0.625%
$800 million – 0.650%
$700 million – 0.700%
$600 million – 0.700%
$500 million – 0.800%
$400 million – 0.900%
$300 million – 1.000%
$200 million – 1.200%
$100 million – 1.500%
$50 million – 2.000%

As I mentioned before, those are retail prices so you might be able to shave a bit from those. Also, at lower price points and/or in deals that are less likely to happen you likely to have a retainer (say $50k) and a minimum transaction fee (say $750k).

Sometimes, if I have a good understanding of the value of the company, I also structure deals giving bankers an upside for selling the company at a premium to my expected value. For instance if I think the company is worth $100 million, I might pay 1.5% on the first $100 million, but 2% on the next $50 million and 2.5% after that. You need to realize that the marginal value of the extra million is worth a lot more to the shareholders than to the bankers who would rather get the deal done.

I hope this provides good guidance!

Side note: IPO fees are very different. For IPOs where the market cap is below $400 million the bankers take 7% of the proceeds split between the book runner and the co-managers.
