# How Much Does It Cost a Startup to Hire a Software Engineer? (2026)

*Published October 25, 2026 · 7 min read · Signals Team*

Every founder knows engineers are expensive. Fewer know the actual number,
because the offer letter only shows one line of it.

This guide breaks down the real cost to hire a software engineer at a US
startup in 2026: the recruiting bill, the fully loaded salary, and the months
of time that never show up on an invoice.

## The short answer

For a US startup, hiring one software engineer costs **$25,000–$45,000 just to
get them in the door**. In the first year, the total runs to **about 1.3–1.5x
their base salary**.

| Level | Typical US base salary | Cost to hire (agency) | First-year all-in cost |
| --- | --- | --- | --- |
| Mid-level engineer | $130k–$170k | $26k–$34k | $170k–$240k |
| Senior engineer | $180k–$240k | $36k–$48k | $240k–$340k |
| AI/ML engineer | $220k–$350k+ | $44k–$70k+ | $300k–$480k+ |

Hiring cost assumes a 20% agency fee. All-in cost is our estimate of salary,
employer taxes, benefits, equipment and hiring cost combined.

## Part 1: What is the cost-per-hire for a software engineer?

The average US cost-per-hire is $5,475 for non-executive roles, according to
[SHRM's 2025 benchmarking data](https://www.shrm.org/in/about/press-room/shrm-releases-2025-benchmarking-reports--how-does-your-organizat).
That number covers every role at every company. For a startup hiring an
engineer, it's off by a factor of five or more.

### Tech recruiter fees

Tech recruiter fees are the biggest line item. Contingency agencies charge 15–30% of first-year
salary, which works out to $18,000–$36,000 for a $120k engineer
([VanHack](https://blog.vanhack.com/the-hidden-tax-on-tech-hiring-why-per-hire-fees-slow-companies-down-in-2026/)).
For a $185k senior engineer at a typical 20% fee, you pay $37,000 the day they
start.

Retained search, where you pay part of the fee upfront, is common for senior and
leadership roles. You pay even if the search fails.

### Sourcing tools and job ads

A LinkedIn Recruiter seat, job board postings and an applicant tracking system
add a few thousand dollars per hire. That's small next to the agency fee, but it
adds up if you skip agencies and run the search yourself.

### Interview time

This is the cost nobody books. A typical engineering loop means a recruiter
screen, a technical screen, a take-home or live coding round, a system design
interview and a founder conversation. Multiply that by every candidate who
reaches each stage.

At a 10-person startup, those interviews are run by your founders and your most
senior engineers. Forty hours of their time on one hire is common. That's a week
of product work that didn't happen.

## Part 2: What is the fully loaded cost of a software engineer?

Base salary is the number you negotiate. It isn't the number that leaves your
bank account. A senior engineer on a $150k salary costs $195,000–$248,000 in
year one once everything else is added
([CodersLink](https://coderslink.com/employers/blog/true-cost-software-developer)).

Here's what sits on top of salary:

- **Employer payroll taxes:** Social Security and Medicare (FICA), plus federal
  and state unemployment tax. Roughly 7–8% of salary for most engineers.
- **Health insurance:** usually the largest benefit. Startups competing for
  engineers tend to cover most or all of the premium, including for families.
- **401(k) match:** optional, but increasingly expected. A 3–4% match is
  typical.
- **Equity:** it doesn't cost cash today, but it dilutes your cap table. Treat it
  as a real cost.
- **Equipment and software:** a laptop, monitors, and seats for GitHub, Slack,
  your cloud tools and AI coding assistants. Budget $3,000–$6,000 a year.

A useful rule of thumb: **budget 1.25–1.4x base salary** for the yearly cost of
an engineer before recruiting. Then add the one-time hiring cost from Part 1 on
top.

## Part 3: How long does it take to hire a software engineer?

The dollar costs above are the easy part to see. The bigger cost for a startup
is how long the seat stays empty, and how long it takes the new person to be
fully useful.

- **Time to hire:** about 49 days on average for a software engineer
  ([BlueOptima](https://www.blueoptima.com/ai-access/8-months-the-real-cost-of-replacing-software-developers)).
  Senior, infrastructure and AI roles often take longer.
- **Ramp to full productivity:** about 4 more months after the start date (same
  study). New engineers need to learn your codebase, your deploy process and
  your customers before they ship at full speed.

Put those together and a role you open today won't run at full capacity for
about six months. For a seed-stage startup with 18 months of runway, that's a
third of your remaining time.

During that ramp you're paying a full salary for partial output. At half
productivity over four months, a $185k engineer represents about $30,000 of
salary that didn't turn into shipped work.

## Why are startup hiring costs higher than at big companies?

Startup hiring costs run higher because large companies spread recruiting costs across hundreds of hires. They have
in-house recruiters, a known brand and a steady flow of inbound candidates. A
startup usually has none of that.

- **No in-house recruiter:** you either pay an agency 20%+ or your founder
  becomes the recruiter.
- **No brand pull:** strong engineers haven't heard of you, so you pay to reach
  them.
- **Founder time is the scarcest resource:** every hour spent interviewing is an
  hour not spent selling, fundraising or building.
- **Each hire matters more:** at a 10-person company, one engineer is 10% of
  your capacity. A bad hire or a slow search hurts far more.

## Worked example: one senior engineer at a US seed-stage startup

A senior backend engineer on a $185,000 base salary, hired through a contingency
agency. These are rough estimates; your numbers will differ.

| Cost item | First-year cost |
| --- | --- |
| Base salary | $185,000 |
| Employer payroll taxes (about 7%) | $13,000 |
| Health insurance | $20,000 |
| 401(k) match (4%) | $7,400 |
| Equipment and software | $5,000 |
| Agency fee (20%) | $37,000 |
| Sourcing tools and job ads | $3,000 |
| Interview time (40 hours at $150/hour) | $6,000 |
| **Total first-year cost** | **about $276,000** |

That's about **1.5x the base salary**. On top of that, the ramp period from
Part 3 means roughly $30,000 of that salary goes to an engineer who isn't yet
fully productive.

## How can startups lower the cost of hiring a software developer?

1. **Build a referral engine.** Referred candidates skip the agency fee
   entirely. Pay a meaningful bonus, such as $5,000–$10,000. It's still a
   fraction of an agency fee.
2. **Use fractional or hourly recruiters.** You pay for hours worked instead of
   a percentage of salary, which is often much cheaper for engineering roles.
3. **Tighten your interview loop.** Fewer, better-designed stages save founder
   time and help you close candidates before a competitor does.
4. **Source where good people are about to leave.** The best time to reach an
   engineer is just before they start looking. Teams going through layoffs,
   reorgs or a stalled product are full of strong people who are open to a
   conversation.
5. **Keep the engineers you already have.** The cheapest hire is the one you
   never have to make.

## The only thing more expensive than hiring an engineer

You've now seen what it takes to add one engineer: often $40,000 or more to
hire, and about 1.5x salary in the first year. The uncomfortable part is that
when an engineer leaves, you pay all of it again, plus the cost of everything
that stalls while the seat is empty.

## Frequently asked questions

**How much does it cost to hire a software engineer in the US?**
For a startup using an agency, expect $25,000–$45,000 in hiring costs.
First-year total cost, including salary, taxes and benefits, is about 1.3–1.5x
base salary.

**What is the average cost-per-hire?**
SHRM puts the US average at $5,475 for non-executive roles in 2025. Engineering
hires through an agency cost several times that.

**How much do tech recruiters charge?**
Contingency recruiters typically charge 15–30% of the engineer's first-year base
salary. Retained search for senior roles is often paid partly upfront.

**How long does it take to hire a software engineer?**
About 49 days on average to fill the role, plus around 4 months for the new hire
to reach full productivity.

**Is it cheaper to use a contractor?**
For a short, well-defined project, often yes. For core product work you'll own
for years, a full-time hire usually wins over time.

## Keep the engineers you already hired

Signals helps founders see which engineers are at risk of leaving 30–90 days
before they resign, while there's still time to act.
