Engineering headcount decisions get made on salary because salary is the number everyone has. It is also the smallest interesting part of the comparison — it ignores what an employee actually costs, it ignores the quarter you spend not having them, and it ignores the fact that the three options being compared are not the same product. This page writes all three out.

What does an employee actually cost?
Take the salary and add the things nobody puts in the spreadsheet. The multipliers below are the standard categories rather than a study — the exact percentages vary by country, benefits package and how you amortise recruiting — but the shape holds everywhere and the shape is the point.
Salary is about 70% of the cost of an employee
Illustrative fully-loaded breakdown for a senior engineer
- Base salary70%
- Employer taxes and statutory costs12%
- Benefits, pension, insurance9%
- Equipment, software, space5%
- Recruiting, amortised over tenure4%
A common planning multiplier is 1.25–1.4× salary, higher in countries with heavier employer contributions. Use your own payroll numbers — the point is that the multiplier exists, not that it is exactly this.
Standard employment cost categories — illustrative proportions, not a survey finding
Employee, contractor, or augmentation?
Three different products. The deciding question is duration and direction — how long you need the capability, and whether you have someone to direct it. Cost follows from those answers rather than driving them.
| Employee | Contractor | Augmentation | |
|---|---|---|---|
| Cost basis | Salary × ~1.25–1.4 | Day rate, no employer costs | Hourly or monthly, vendor absorbs employment |
| Time to productive | 60–90+ days to hire, then ramp | Days to weeks | Days to weeks |
| Right when | The capability is permanent and core | A specific skill, a defined period | A bounded workstream, or capacity you cannot hire fast enough |
| You supply | Management, career path, retention | Technical direction and review | A definition of done; a pod brings its own lead |
| Real risk | A slow hire, or the wrong one, at maximum cost | Bus factor of one, and status questions in the UK | Knowledge leaving when the engagement ends |
Does the fully-loaded maths differ in the UK?
The categories are the same; the weights are not, and the comparison between an employee and a contractor moves further than the employee number does. Rather than borrow a multiplier, take last year's actual payroll and divide by base salaries — the categories below are what you will find inside it.
| Cost category | US | UK |
|---|---|---|
| Employer payroll taxes | Social security and Medicare contributions, plus state unemployment insurance | Employer National Insurance, plus the Apprenticeship Levy above the payroll threshold |
| Retirement | Optional; a 401(k) match is competitive rather than compulsory | Auto-enrolment pension contributions are a statutory minimum, not a benefit decision |
| Healthcare | Usually the largest single non-salary line | Typically a smaller private top-up rather than primary cover |
| Leave | No federal statutory minimum; set by the employer | Statutory minimum annual leave, so the cost is fixed rather than a policy choice |
| Ending the engagement | Generally at-will, so the exit cost is low and the risk sits with the employee | Notice and statutory process mean a wrong hire is slower and costlier to unwind |
Why are rates falling while AI skills cost more?
Because they are two different markets moving in opposite directions. Accelerance recorded rate declines across every major region during 2025, which is a supply story — more available engineers, including many from the layoffs above. PwC's barometer, over more than a billion job ads, has AI-skilled roles carrying a 62% wage premium and growing at 69% against 9% for the overall market, which is a scarcity story in a narrow band.
| Region | Junior | Senior | 2025 movement |
|---|---|---|---|
| Latin America | $33–45 | $60–75 | −7.1% |
| Central & Eastern Europe | $31–39 | $64–76 | −4.4% |
| Asia | $24–31 | $31–41 | ~−8% |
What does a bad hire cost?
Less than the internet says, and in a different currency. The figure quoted everywhere — 30% of first-year earnings, attributed to the US Department of Labor — has no locatable Department of Labor publication behind it. We have looked. The alternative, CareerBuilder's $14,900, is close to a decade old and the original release is difficult to find.
What changes if you are hiring in the UK?
The status question, and it changes who carries the risk rather than what the work costs. Contractor-sector surveys report engagements assessed as outside IR35 falling to around 70% in 2025/26, from 80% in both 2023 and 2024. Separately, the small-company thresholds rose for financial years beginning on or after 6 April 2025 — turnover from £10.2m to £15m and balance sheet from £5.1m to £7.5m — which takes some engagers out of scope entirely.
Where augmentation is the wrong answer
- The capability is permanent and core. Hire. Over years the maths is not close, and the institutional knowledge compounds where you want it.
- You have nobody to set technical direction. Adding engineers to an organisation with no engineering leadership adds coordination, not output.
- You need one specialist for three months. That is a contractor-shaped problem, and a pod is the wrong unit.
- You are optimising purely on rate. Then the comparison you actually want is regional, and the offshore shortlist covers it directly.
Common questions
What multiplier should I use for fully-loaded cost?
Between 1.25 and 1.4 times salary is the usual planning range, and higher in countries with heavier employer contributions. Rather than adopting a number, take last year's actual payroll and divide by base salaries — you will get your own multiplier, which is the only one that is evidence for your business.
Is it cheaper to hire offshore directly rather than through a vendor?
On rate, yes. You then take on the employment entity, local compliance, payroll, equipment and the recruiting itself — which is a business you have started rather than a cost you have cut. It makes sense at a certain scale and is expensive below it, and the crossover is usually further away than it looks. The staff augmentation shortlist compares the vendors built for the middle ground.
How do I verify seniority before committing?
A structured technical conversation about work they actually did, with follow-up questions on the decisions rather than the outcomes. Ask what they would do differently and why — the answer separates people who owned decisions from people who were nearby when decisions happened, and it is difficult to rehearse.
Does AI tooling reduce how many engineers I need?
Not reliably, and the evidence points the other way on review effort. In the Stack Overflow 2025 survey 66% of developers named "solutions that are almost right, but not quite" as their top frustration and 45.2% said debugging AI-generated code took longer than writing it. Tooling shifts effort from typing to reviewing; plan for the review capacity.
How should I compare an agency quote against a headcount plan?
Over the real duration, with the vacancy period included on the headcount side and the ramp included on both. A fixed-price engagement and a salary are not comparable as monthly numbers — compare total cost to a defined outcome, and be explicit about who carries the overrun risk in each case.
The short of it
Cost the employee fully, price the vacancy, and then compare three genuinely different products over the duration you actually need. Do not use the 30% figure. And treat falling rates as a reason to check seniority more carefully, not as a discount to bank.
