What 24/7 In-House DevOps Really Costs
Pick a country and the in-house setup you are weighing. You see the yearly cost, what one engineer costs line by line, and how much shared 24/7 cover from Valletta saves against it. Every number comes from market salary data and the sources listed below.
How much does an in-house 24/7 DevOps team cost?
A minimum 24/7 rotation of four mid-senior DevOps or SRE engineers costs $832,000 a year in the US or £441,800 in the UK, plus $112,000 or £64,000 to hire them. Two engineers sharing a pager cost half that and still leave gaps. Google’s guidance of eight engineers costs $1,664,000 or £883,600 a year.

What does a DevOps engineer cost in salary and overheads?
The median base salary for a mid-senior DevOps or SRE engineer is about $140,000 in the US and £80,000 in the UK. Benefits, payroll taxes, pension, on-call pay and tooling take the fully loaded cost to $208,000 and £110,450 a year, so salary is only 67 to 72 percent of the bill.
| One mid-senior DevOps/SRE engineer, per year | United States | United Kingdom |
|---|---|---|
| Base salary, market median | $140,000 | £80,000 |
| Benefits, payroll taxes, pension | $49,000 | £18,450 |
| On-call allowance, about 10% of base | $14,000 | £8,000 |
| Tooling, training, equipment | $5,000 | £4,000 |
| Fully loaded cost | $208,000 | £110,450 |
Each hire typically costs a 15 to 25 percent agency fee on top: about $21k to $35k in the US or £12k to £20k in the UK. Replacing someone who leaves costs between half and twice their salary.
How much is on-call compensation for DevOps engineers?
Our model sets on-call pay at about 10 percent of base salary: $14,000 a year for a US engineer on $140,000 and £8,000 for a UK engineer on £80,000. It is one of four overheads on top of salary, next to benefits and taxes, and tooling, training and equipment at $5,000 or £4,000 per engineer.
A rotation still needs enough engineers to share the nights and weekends, so team size moves the total far more than the on-call allowance does.
How many engineers does 24/7 on-call need, and what does each team cost?
Google’s SRE book puts the minimum for a single-site 24/7 on-call rotation at eight engineers. Four is the smallest team that covers every hour of the week. Two engineers sharing a pager is what most companies have, and one holiday or resignation breaks it. The yearly cost doubles with each step.
| In-house team, per year | United States | United Kingdom |
|---|---|---|
| Lean: 2 engineers sharing a pager | $416,000 | £220,900 |
| Minimum 24/7: 4 engineers | $832,000 | £441,800 |
| Google SRE guidance: 8 engineers | $1,664,000 | £883,600 |
| One-off: hiring a team of 4 | + $112,000 | + £64,000 |
The lean option does not give continuous cover: one holiday or one resignation and the rotation is gone.
How much does shared 24/7 cover save?
Against a 4-engineer in-house team, Valletta 24/7 support costs 63 to 97 percent less, depending on the tier and on whether the team would be in the US or the UK. Against two engineers sharing a pager the saving is 26 to 93 percent. Every tier includes the same rotation, priority ladder and reporting.
| Valletta engagement | Saving vs US team | Saving vs UK team |
|---|---|---|
| Essentials: 24/7 cover with a small monthly allowance of hands-on hours | 97% | 95% |
| Standard: 24/7 cover plus about one engineer-month of work | 87% | 82% |
| Extended: 24/7 cover plus about two engineer-months of work | 75% | 63% |
Saving against an in-house team of 4 engineers, hiring costs excluded. Every tier includes the same rotation, priority ladder and reporting. Against the lean two-person setup, which cannot deliver continuous cover, the saving is still 26 to 93 percent.
Which assumptions sit behind the calculator?
The calculator uses 2026 market salaries for a mid-senior DevOps or SRE engineer, the overheads that come with them, and the team size continuous cover needs. US figures are in dollars and UK figures in pounds. Savings compare Valletta standard engagement pricing with a 4-engineer team, hiring excluded, at £1 = $1.30.
- US salary: $140,000 base, within the 2026 market composite for DevOps ($119k to $143k) and SRE ($132k to $155k) from Glassdoor, ZipRecruiter, PayScale and Built In, via KORE1 (2026).
- US overheads: benefits and payroll taxes at 35% of base. BLS reports benefits at 30% of total private-sector compensation (June 2026), equal to about 43% of wages, so 35% is conservative.
- UK salary: £80,000, the median permanent SRE salary on IT Jobs Watch for the six months to 26 October 2026.
- UK overheads: employer National Insurance at 15% above £5,000 (2026/27), 5% employer pension and £2,000 of other benefits.
- On-call and tooling: on-call allowance at 10% of base; $5,000 or £4,000 per engineer for tooling, training and equipment.
- Hiring: agency fees of 15% to 25% of first-year pay (20% used); replacing someone who leaves costs between half and twice their salary (Gallup, via KORE1).
- Team size: Google SRE book, "Being On-Call": eight engineers minimum for a single-site on-call rotation.
- Savings: Valletta standard engagement pricing against the 4-engineer team, hiring excluded; £1 = $1.30.
Where to go from the numbers
The DevOps support hub explains the rotation and the response targets behind the saving. The managed Kubernetes page covers what we run on your clusters, and the AWS comparison explains how a 24/7 rotation works next to an AWS Support plan. A call turns these averages into a comparison with your own numbers.

Frequently asked questions
For a mid-senior DevOps or SRE engineer the calculator uses $140,000 in the US, within the 2026 market composite of $119k to $143k for DevOps and $132k to $155k for SRE, and £80,000 in the UK, the median permanent SRE salary reported by IT Jobs Watch. Salary is 67 to 72 percent of the full cost.
About $208,000 a year in the US and £110,450 in the UK. That adds benefits, payroll taxes and pension ($49,000 or £18,450), an on-call allowance of about 10 percent of base ($14,000 or £8,000) and tooling, training and equipment ($5,000 or £4,000) to the base salary.
Google’s SRE book states eight engineers as the minimum for a single-site 24/7 on-call rotation. Four engineers is the smallest team that covers every hour of the week, at $832,000 a year in the US or £441,800 in the UK. Two engineers sharing a pager is cheaper but cannot give continuous cover.
Agency fees run at 15 to 25 percent of first-year pay. At 20 percent, hiring a team of four costs about $112,000 in the US or £64,000 in the UK, before the first salary is paid. Replacing someone who leaves later costs between half and twice their salary, according to Gallup.
Our price depends on your stack, the size of your estate and how much hands-on work you want with the cover, so we publish the saving range and our rate, from $45 per hour, instead. Send us your stack and current support setup and we come back with a side-by-side comparison and a fixed proposal.
Our published savings compare each tier with a 4-engineer team, and with the lean two-person setup as a range. Against an 8-engineer team, the size Google recommends, the in-house cost doubles again, and we quote the saving on a call against your own scope rather than publish a figure we have not modelled.
