When it comes to choosing between an investment banker and a financial advisor, one of the key considerations is the cost involved. Investment bankers typically charge higher fees compared to financial advisors for their services. This article will compare the cost structure of both and look at the reasons for the fee difference.

Investment bankers charge fees in the millions due to the nature of their services
Investment bankers provide high-value services like IPOs, mergers and acquisitions for which they charge fees running into millions of dollars. The fee is usually a percentage of the transaction value. So for billion dollar deals, their fees can be tens of millions. Financial advisors on the other hand work with individual clients and small businesses for whom such high fees would be prohibitive. So financial advisors usually charge an annual fee based on assets under management or fixed project fees.
Investment bankers undertake high risk, high reward activities
Investment bankers advise on complex, high risk transactions like IPOs and mergers & acquisitions. They also commit capital to underwrite securities issuances. The high fees they charge are commensurate with the risks undertaken and value created from large transactions. Financial advisors provide guidance to individuals on portfolio allocation, taxes, retirement planning etc. These activities carry lower risks, so the fees charged are also comparatively lower.
Investment bankers have higher overhead costs
Investment banks require huge investments in IT infrastructure, market data, trading platforms and research capabilities. They also pay top dollar for star bankers. Such high overheads necessitate charging higher fees for their services. Financial advisors run leaner operations with lower overhead costs. So they can afford to charge lower fee rates.
Investment bankers provide access to capital markets
A key service investment bankers provide is access to capital markets for debt and equity financing. Companies are willing to pay big fees for this access. Financial advisors do not provide capital raising services. Their focus is on assessing client portfolios and making customized investment recommendations.
Investment bankers have specialized expertise
The top investment bankers possess specialized expertise in areas like M&A, IPOs, derivatives, structured products etc. Their expertise combined with strong relationships with institutional investors enables clients to pay high fees. Most financial advisors have generalized expertise to assess portfolios and financial situations of retail clients.
To summarize, investment bankers charge substantially higher fees compared to financial advisors primarily due to the scale, risks and specialized nature of their services and skills.
