Underwriter fees on a securities offering are almost always structured as a single percentage called the gross spread, which runs 5% to 7% of the offering price for most mid-sized IPOs and drops well below that for billion-dollar deals. The spread is the difference between what investors pay for shares and what the underwriter pays the issuing company, and it covers everything the syndicate does: guaranteeing the proceeds, marketing the shares, running due diligence, and absorbing the risk that the offering falls flat. The percentage is negotiated fresh for every transaction, and the issuer never writes a check, since the fee comes out of the sale itself.
How the Gross Spread Works
If shares are offered to the public at $50 each and the syndicate pays the issuer $46.50, the $3.50 difference per share is the gross spread. In that example it works out to 7%. The company’s net proceeds are what remain after the spread is deducted.
Because the fee is a percentage, it scales with the size of the deal. A company raising $100 million at a 7% spread pays $7 million in underwriting compensation. A company raising $500 million at the same percentage pays $35 million. That arithmetic is one reason larger deals negotiate lower percentage fees.
The Three Parts of the Spread
The gross spread is divided into three components, each tied to a different job inside the syndicate. The management fee goes to the lead bookrunner for structuring the deal, coordinating the syndicate, and running due diligence. The underwriting fee compensates syndicate members for the capital risk of buying shares from the issuer and holding them until they resell. The selling concession pays the brokers and salespeople who actually place shares with investors.
The typical split is roughly 20% management fee, 20% underwriting fee, and 60% selling concession, a ratio widely treated as an industry norm alongside the 7% gross spread itself.1Aalto University.

What the Fees Actually Pay For
The spread isn’t a finder’s fee. It buys a set of services that take months of work before shares ever trade.
Due Diligence and Legal Liability
Underwriters run an extensive financial and legal investigation of the issuer before the offering. This isn’t optional. Under Section 11 of the Securities Act, every underwriter faces personal civil liability if the registration statement contains a material misstatement or omission, and their only defense is proving they conducted a reasonable investigation and had genuine grounds to believe the disclosures were accurate.2Office of the Law Revision Counsel. 15 USC 77k – Civil Liabilities on Account of False Registration Statement A significant portion of the spread effectively pays for the work that establishes that defense.
Marketing and Book-Building
The syndicate markets the offering through roadshows, where management and lead bankers meet institutional investors in person to pitch the company and gauge demand. Those events cost real money and consume weeks. Alongside them, the lead underwriter runs book-building, collecting non-binding indications of interest that shape the final price and how shares are allocated. Getting the price wrong either leaves money on the issuer’s table or produces a deal that trades down on day one.
Price Stabilization
After trading begins, underwriters use stabilization tools to keep the stock from falling apart in its first days. The main one is the overallotment option, often called the green shoe, which lets the syndicate sell up to 15% more shares than originally offered. The underwriters short-sell those extra shares during the offering. If the price drops, they cover the short by buying in the open market, which supports the price. If the price holds or rises, they exercise the option and buy the additional shares from the issuer at the offering price. Either way, the mechanism cushions the most volatile stretch of a new stock’s life.
What Drives the Percentage
The 7% Norm for Mid-Sized IPOs
For IPOs raising between $20 million and $100 million, the gross spread has clustered at exactly 7% with striking consistency. SEC-published research found that more than 90% of IPOs in that size band paid a 7% spread during the late 1990s, and follow-up work showed 94% of deals in that bracket still paid exactly 7% through 2018.3U.S. Securities and Exchange Commission. Data Appendix – The Middle-Market IPO Tax Whether you read that as the fair price of risk or as an entrenched convention, it’s the baseline a mid-market issuer negotiates from.
Deal Size
The percentage drops sharply as offerings get larger. For IPOs raising $1 billion or more, the mean gross spread has averaged around 4.4%, with individual deals varying widely based on the issuer’s profile and leverage. Visa’s $17.9 billion IPO carried a 2.8% spread. Facebook’s $16 billion offering priced at 1.1%. General Motors paid just 0.75% on its $15.8 billion IPO, and Uber’s $8.1 billion deal came in at 1.3%.4University of Florida.

Market Conditions
The broader market shifts the underwriters’ risk calculus. When investor appetite for new issues is strong, the risk of unsold shares is lower and the spread can tighten. In volatile or bearish periods, that risk rises and so does the fee. Issuers going to market during a downturn have less leverage, because fewer banks want to guarantee proceeds when they may end up holding depreciating inventory.
Firm Commitment vs. Best Efforts
The type of underwriting agreement decides who carries the risk of unsold shares, and that changes what the fee is really paying for.
Under a firm commitment agreement, the syndicate buys all of the offered shares from the issuer at the agreed net price and resells them to investors. The issuer gets its guaranteed proceeds no matter what happens next. If demand disappoints and shares can’t be placed at the offering price, the syndicate absorbs the loss. Firm commitment is the standard arrangement for IPOs and large secondary offerings, and the risk transfer is the main justification for the full gross spread.
In a best efforts deal, the underwriter acts as an agent instead of a buyer. The bank agrees to market the shares and try to place them, but makes no guarantee about how many will sell. If demand is weak, the issuer falls short of its capital target. You might assume the fee would be dramatically lower given that the bank isn’t putting capital at risk, but that isn’t always the case. Best efforts agreements filed with the SEC show commission structures that still reach 6% to 7% of gross proceeds for smaller deals, sometimes with warrants and advisory fees layered on top.5U.S. Securities and Exchange Commission. Underwriting Agreement – ADOMANI, Inc. These arrangements appear most often with smaller underwriters, higher-risk offerings, or secondary deals where the bank prefers not to commit capital.
Costs Beyond the Spread
The gross spread is the headline number, but it isn’t always the full cost. Two other line items show up regularly in offering documents.
Warrants and Equity Compensation
Underwriters sometimes receive warrants or options to buy the issuer’s stock at the offering price as part of the fee package. This is more common in smaller offerings where the bank wants upside beyond the cash spread. FINRA regulates these arrangements under Rule 5110, which limits warrants received as underwriting compensation to a five-year exercise period from the start of sales, bars favorable anti-dilution protections beyond what public shareholders get, and restricts registration rights.6FINRA. FINRA Rule 5110 – Corporate Financing Rule – Underwriting Terms and Arrangements The value of the warrants counts toward total underwriting compensation and has to be reported to FINRA using a valuation formula in the rule.
Expense Reimbursements
Issuers commonly reimburse underwriters for out-of-pocket costs from the offering, including legal fees, roadshow travel, and printing. Some agreements include an unaccountable expense allowance that can run 2% to 3% of gross proceeds on top of the spread. For a company focused on the headline percentage, these add-ons are a real cost worth negotiating.
Where to Find the Fees on a Specific Deal
Underwriting fees aren’t negotiated in the dark. Before a public offering can proceed, FINRA reviews the terms under Rule 5110. Every member firm in the syndicate has to file details of the arrangement, including the estimated maximum value of each item of underwriting compensation, any warrant agreements, and any securities acquired during the review period.6FINRA. FINRA Rule 5110 – Corporate Financing Rule – Underwriting Terms and Arrangements FINRA evaluates whether the total package is fair and reasonable given the offering size, the risk assumed, and the type of securities. Deals that cross the line get renegotiated before launch.
On the SEC side, Regulation S-K Item 508 requires the issuer to include a detailed table in the prospectus showing the nature and amount of all underwriting discounts and commissions. The table breaks out amounts paid by the company versus any selling shareholders and includes every item FINRA considers underwriting compensation. When the deal has an overallotment option, the prospectus shows both maximum and minimum scenarios.7eCFR. 17 CFR 229.508 – Item 508 Plan of Distribution For anyone trying to see what a specific offering actually cost, the prospectus fee table is the reliable source, and it’s publicly available through the SEC’s EDGAR filing system.
