What does a fractional CTO cost?
UK providers are advertising £600 to £2,500 a day, with most of the market between £1,000 and £1,600 and retainers from about £2,500 a month for two days to about £9,600 a month for two days a week. As a single planning figure, use about £1,400 a day in the UK and $2,500 a day in the US. Per day that is close to what a full-time CTO costs. It is cheaper in total because you buy one to three days a week rather than a permanent hire.
Enough to set a budget, not a rate card. The number that matters is what the decision in front of you is costing while it stays open.
How much does a fractional CTO cost, by market?
Sized for venture backed companies from seed to Series B, not enterprise pay scales.
United Kingdom
£1,400 a day
Upper half of the £1,000 to £1,600 band most UK providers advertise for an experienced executive. Specialist and regulated mandates sit higher.
A full-time CTO can cost around £180,571 a year on a £150,000 base once employer National Insurance, pension and benefits are added, before equity.
United States
$2,500 a day
Mid point of published US embedded ranges. Concentrated advisory and diligence work prices above it.
A full-time CTO on a $218,000 base can cost around $261,463 a year loaded, before equity. Seed stage sits nearer $134,000 base.
Singapore
S$1,411 a day equivalent
No credible source publishes a Singapore fractional day rate, so the reference point is the daily cost of the CTO you would otherwise hire.
A full-time CTO on a S$280,000 base can cost around S$310,320 a year once CPF and benefits are added. Advertised market data rather than a stage specific benchmark.
Treat these as budget anchors. No credible dataset publishes a true fractional CTO median, so each figure is a point inside published 2026 provider and recruiter ranges, not a quote.
What the market is currently advertising
Prices read from published provider pages on 25 August 2026. Rows are described by locale and by the type of engagement being sold, not by provider, because the useful information is the spread rather than who is asking for what.
| Locale | Type of engagement | Advertised day rate | Advertised monthly retainer |
|---|---|---|---|
| United Kingdom | Productised part-time CTO packages, tiered by days bought | £800 to £1,600 | £2,499 to £9,599, two days a month up to two days a week |
| United Kingdom | Fractional executive search and recruitment practice | £1,000 to £2,500 | Not published |
| United Kingdom | Fractional director placement network | £1,000 to £1,600 | £3,000 to £7,000 on a one to two day a week retainer |
| United Kingdom | Boutique fractional CTO practice with a published rate calculator | £900, £1,200 or £1,600 by track record | About £9,600 at two days a week on the middle band |
| United Kingdom | Fractional executive marketplace, guidance to practitioners on pricing | £600 to £1,600 | Not published |
| United States | Marketplace observed rates across supply and demand signals | About $1,700 at eight hours; $216 an hour average, $170 to $250 middle half | Not published |
| United States | Embedded retainer, boutique advisory | $1,500 to $4,000 | $8,000 to $25,000 for twenty to sixty hours |
| United States | Concentrated advisory and board level day work | $2,500 to $5,000 | $10,000 to $30,000 for two to four days a month |
| United States, United Kingdom, Singapore and others | Practitioner survey, fifty or more working fractional CTOs | Not published | $15,000 median at two days a week |
These are asking prices, not a survey. I am showing them because they are useful for setting a budget, not because they amount to an independent benchmark. Nobody samples this market properly, so treat any single figure, including mine, as a starting point for a conversation.
The finding is the spread. The top of the advertised UK market is about four times the bottom for a role with the same title, and the same practice will price a productised package and an accountable executive engagement as if they were the same product. That gap is a seniority gap, not a discount.
Against a full-time hire the picture is steadier. Two days a week at £1,400 is about £129,000 a year, against roughly £180,571 loaded for a London startup CTO before equity. No published source quotes a fractional rate in Singapore dollars, so Singapore buyers are quoted in US dollars by the same practitioners, or plan against the daily cost of the hire they would otherwise make.
What moves the number
What the engagement is answerable for
An audit with recommendations prices differently from standing accountability for delivery, suppliers, security and spend.
Cadence
One to three days a week is the usual shape. A single high stakes day costs more per day than a standing arrangement.
Sector, risk and travel
Regulated and AI heavy work carries a premium. Remote by default; on-site time is quoted separately and agreed in advance.
Background reading: how to find an experienced fractional CTO
How I work, and what that costs
It depends on what you need. Some engagements are light: a board seat, a monthly cadence, a second opinion on the technology strategy before a decision is taken. Others are hands on: owning delivery, suppliers, hiring and security through a turnaround. I have done both, and the shape sets the cost more than anything else.
So the sensible starting point is the decision in front of you, not a rate. The cost that usually matters is not the day rate anyway. It is the build that runs months late, the agency invoice nobody is checking, the architecture decision unwound after the round, or the security questionnaire that stalls an enterprise deal for a quarter. If a short piece of advice settles it, that is what I will propose.
Common questions
- How much does a fractional CTO cost in 2026?
- UK providers are currently advertising £600 to £2,500 a day, with most of the market between £1,000 and £1,600, and monthly retainers from about £2,500 for two days a month to about £9,600 for two days a week. As a single planning figure, use about £1,400 a day in the UK and about $2,500 a day in the US, higher for specialist or regulated work.
- What are UK fractional CTOs currently advertising?
- Checked on 25 August 2026, published UK day rates span £600 to £2,500. Productised packages start around £800, placement networks and boutique practices cluster at £1,000 to £1,600, and executive search practices quote up to £2,500. The top of the advertised market is roughly four times the bottom, which tells you these are asking prices rather than a market rate.
- Is a fractional CTO cheaper than a full-time CTO?
- Not per day. It is cheaper in total spend, because you buy one to three days a week instead of a permanent hire with employer costs, equity and a search fee. At seed to Series B most companies buy a few days a month.
- What does a typical arrangement look like?
- One to three days a week, agreed in advance against a defined set of outcomes. Below one day a month there is not enough contact to hold anything to account. Above three days a week, the honest question is whether you need an interim or a permanent appointment.
- Do you charge for the first conversation?
- No. The first conversation works out whether there is a problem I can help with. If you do not need a fractional CTO, I will say so.
