Fractional CTO pricing has the widest spread of any role on this site, because the role ranges from a few hours of advice a month to two days a week running an engineering team. Published fees run from about $3,000 a month for on-call advice to around $15,000 a month for an embedded role. Talent marketplaces quote $100 to $250 an hour. The table below this guide lists what firms on this site publish.
Three common levels
- On-call advisory, 4 to 20 hours a month: about $2,500 to $5,000. Architecture questions, vendor reviews, help with hiring and a monthly check-in.
- Standing role, 40 to 80 hours a month: about $6,000 to $12,000. Runs technical planning, oversees the development team or agency, reviews code and owns security basics.
- Embedded, two days a week or more: $12,000 to $15,000 and up. Manages engineers directly, attends product and leadership meetings and carries the technical roadmap.
What drives the price
The size of the team being led drives the most. Overseeing one outside agency is lighter work than managing eight in-house engineers. Technical complexity comes next: regulated data, real-time systems, hardware, marketplaces with payments and machine learning components all need specialist experience. Location still matters at the margins. Practitioners based in lower-cost regions often price below US and UK rates for similar experience, and nearshore development firms frequently bundle a CTO with their engineering teams. Finally, check the notice period, since month-to-month arrangements sometimes carry a higher monthly rate.
Projects and day rates
Fixed-fee projects are common for CTOs. Technical due diligence before an investment or acquisition typically runs $5,000 to $25,000 depending on codebase size and the depth of the report. An architecture review with a written plan runs similar amounts. Vendor selection, a cloud cost review or a hiring sprint for a first engineering lead are other common projects. Day rates typically run $1,200 to $2,500.
Equity and cash
CTOs are the fractional role most likely to be offered equity, because early startups need technical leadership and lack cash. Typical grants are a fraction of a percent to around 1%, vesting over two to four years, in exchange for a reduced retainer. Larger grants usually mean the person is a co-founder, which is a different conversation. Put any equity in a written advisor or consulting agreement with vesting and an IP assignment.
Bundled with development
Many providers sell a CTO as part of a development contract. The CTO fee then looks low or disappears, and the cost sits in engineering hours. Compare the total monthly spend, and ask who reviews the engineers’ work if the CTO works for the same firm.
What the first month costs in time
Plan on 4 to 8 hours of the founder’s time in month one: a walkthrough of the product and roadmap, access to the code repository, cloud accounts and vendor contracts, and introductions to engineers or the agency. Engineers should expect a review session each.
How to read a quote
Check the hours behind the fee, whether code review and hands-on work are included, who owns work product and accounts, the notice period, whether the provider also sells development and what the first month delivers in writing. A strong first deliverable is a short report on what to fix, what to keep and what to stop paying for.
