Fractional CTO Cost: What the Published Rates Say and What They Leave Out

One published rate card, from a firm with fractional leaders to sell

We could not find a neutral survey of what fractional CTOs charge. What exists are guides written by firms that sell or place these people, which is a bit like asking a car dealer for the fair price of a truck. The dealer may even be right. The Fractionus guide dated June 23, 2026 is the clearest one we found, and we quote it with that warning attached.

Read that table as a menu, not a benchmark. The same guide says engagements run from one day a week to three or more, so one title at one firm can describe very different amounts of work. Compare hours and scope across proposals. The title on the letterhead proves very little, which may be why so many people now have it.

Hours times rate, which is the whole trick

Every fractional quote reduces to a multiplication that a proposal should be willing to show you. The table below applies the published hourly range to a few monthly hour counts. The rates are from the Fractionus guide. The arithmetic and the right-hand column are our own judgment. DataCram's price comes a little further down.

Day rates behave the same way. One day a week is about 4.3 days a month, or roughly $7,800 to $17,300 at the published day rates. Three days a week is about 13 days, or roughly $23,400 to $52,000, well past the top of the $22,000 retainer. We cannot tell you how that firm squares those figures. We can tell you to ask any vendor what its retainer buys in hours, in writing.

A seed-stage app and a 40-truck contractor do not buy the same hours

Much of the gap between low and high comes down to how close the technology sits to the money. Three invented companies show why. We have no neutral data on what each kind actually pays, so take this as reasoning and not as a benchmark.

The practical lesson runs in both directions. A small company should not pay for startup-grade hours when it has no startup-grade work. A startup should not buy ten hours a month and expect someone to lead its product. If a proposal is the same for all three of those made-up companies, it was written before anyone looked at yours.

The invoices that arrive after the retainer

A fractional fee buys decisions. It does not pay for carrying them out. The larger numbers usually live in the lines below, and a proposal that skips them is incomplete, however tidy it looks. We list no market figures for these because we do not have sourced ones. Your own invoices are the better source anyway.

A part-time CTO might find waste in those lines. Might. We will not put a savings figure on a sales page, because we have not seen your invoices. The developer line is where a builder earns the fee. Casey Kinnison, who holds DataCram's seat, builds custom software and designs databases, so a developer's estimate can be checked against the code. If you want to see what a site costs to keep alive, the website maintenance cost guide is a reasonable start.

Our fee, and the prices we do publish

At DataCram the seat is held by Casey Kinnison, the company's founder and lead developer. The seat starts at $5,500 a month for 15 hours. That is about three and a half hours a week and about $367 an hour by our arithmetic, inside Fractionus's published $250 to $500 hourly range. It also sits below the $9,000 where that firm's retainers begin, though its guide describes at least a day a week. More hours cost more, so you get the exact figure after a first conversation and before any work starts. What the fee covers does not vary: a set number of hours a month, a standing weekly or biweekly meeting, a written plan and one monthly page of numbers. The fractional CTO overview describes how that runs.

The hands-on work has public prices, and buying any of it from us is optional. As of November 2026, on our pricing page:

• Web apps and portals and integrations start at $575, depending on complexity. API integrations go live the same day.
• iOS or Android apps start at $3,750.
• Websites start at $1,500 by page count, with 0% financing at 25% down for up to 12 months.
• Hosting and maintenance starts at $55 a month, and Kairos AI chat and booking starts at $575 plus a monthly plan.

How to set a budget before anyone quotes you

1. 1

   Add up what you spend now

   Pull twelve months of card statements and vendor invoices, and total them. That number is the baseline the whole job answers to.

2. 2

   Estimate the hours honestly

   Rented software and a good IT company point toward the top rows of the hours table. A product your customers log in to points toward the bottom rows.

3. 3

   Multiply by the published range

   Use $250 to $500 as a rough bracket, remembering who published it. A quote well outside the bracket is not automatically wrong, but it should come with a reason.

4. 4

   Set aside money to act

   Pick a separate figure for carrying out what the plan recommends. If that figure is zero, wait. A plan with no budget behind it is a hobby.

5. 5

   Hold it against a full-time hire

   The BLS median for computer and information systems managers was $175,140 in May 2025, a broader category than CTO. At the 70/30 split BLS reported for private industry in June 2026, we estimate about $250,000 in total cost, or about $20,800 a month.

That last step holds a fact the fractional sales pitch tends to skip. Annualized, the Fractionus retainer range is $108,000 to $264,000. The top of it costs more than our estimate for a median manager, though a real CTO would likely cost more than that median. Somewhere up there, the case for a full-time hire gets strong. If your budget is headed that way, read that page before you sign anything.

Two proposals on one table, when the titles match

A trader sets the exit before the entry, and Casey Kinnison worked as one. The "Leaving" row above is that habit written into a contract, and it costs nothing to ask for on the day you sign.

Before you compare anything, get your own facts straight. A free website health check or site audit costs nothing and gives each bidder the same starting point. Then tell us your hours and scope and a person will reply with a quote after a first conversation. If your marketing spend has the same problem, the fractional CMO section runs this same exercise on that bill.
