What Is the Fully Loaded Cost of a Software Engineer?

A US software engineer’s fully loaded cost is usually about 1.25x–1.45x base salary. Using the BLS May 2025 median software developer wage of $135,980, a realistic employer budget is roughly $170,000–$197,000 per year before equity, bonuses, office space, and unusual state-specific costs.

What should you include in fully loaded engineer cost?

“Fully loaded” means the annual cost to employ the engineer, not just what appears in the offer letter. For US W-2 employees, include:

• Base salary
• Employer payroll taxes
• Health, dental, vision, disability, and life insurance
• Retirement contributions
• Paid leave and holidays
• Recruiting and onboarding cost
• Laptop, monitor, security tools, IDEs, SaaS seats, and cloud/dev environments
• State unemployment insurance and workers’ compensation
• Optional bonus, equity, relocation, and office costs

The cleanest quick estimate is salary multiplied by a load factor. BLS reported that, for private-industry workers in June 2026, employer costs averaged $46.89 per hour in total compensation, including $32.82 in wages and salaries and $14.07 in benefits. That implies a broad private-sector load factor of about 1.43x wages (BLS Employer Costs for Employee Compensation).

For software engineers, the percentage can be lower or higher. Health insurance is partly fixed, so it is a smaller percentage for a high-paid senior engineer than for a junior employee. But equity, bonuses, high-end equipment, recruiting fees, and rich benefits can push the real number above the simple BLS multiplier.

How do the numbers work for a median US software engineer?

The BLS Occupational Outlook Handbook reports a May 2025 median annual wage of $135,980 for software developers, with the lowest 10% below $82,460 and the highest 10% above $214,670 (BLS Software Developers). Here is a practical first-year model for a median-salary hire.

The payroll tax assumptions come from IRS 2026 rules: employer Social Security is 6.2% up to the $184,500 wage base, employer Medicare is 1.45% with no wage base, and FUTA is 6.0% on the first $7,000, generally reduced to 0.6% when the employer receives the maximum state unemployment credit (IRS Topic 751, IRS Publication 15).

For health insurance, KFF’s 2025 employer survey found average annual premiums of $9,325 for single coverage and $26,993 for family coverage. Workers contributed $1,440 for single coverage and $6,850 for family coverage on average, leaving implied employer contributions of $7,885 and $20,143 respectively (KFF Employer Health Benefits Survey).

Retirement costs vary by plan. SHRM’s 2025 benefits survey reported an average traditional 401(k) employer match of 6.30%, while many hiring models use a lower assumed match when not every employee contributes enough to receive the maximum (SHRM 2025 Benefits Survey). SHRM also reported a $5,475 average cost per nonexecutive hire in its 2025 benchmarking release (SHRM 2025 Benchmarking Reports).

What multiplier should hiring managers use?

Use a 1.25x salary multiplier for a lean remote-first company with single-coverage assumptions, modest retirement match, limited recruiting spend, and no cash bonus. Use 1.35x–1.45x when you offer stronger benefits, family coverage subsidies, bonuses, paid leave, premium equipment, and dedicated recruiting support.

For the median US software developer salary of $135,980, that gives this planning range:

Do not ignore state-level costs. State unemployment insurance, workers’ compensation, paid family leave, local payroll taxes, and pay-transparency compliance can move the final number. Also separate recurring annual cost from first-year cost: recruiting fees and laptop purchases are front-loaded, while health premiums, payroll taxes, SaaS seats, and retirement contributions repeat.

If the US loaded cost is too high for the role, compare it with remote hiring options before cutting seniority. OctogleHire, for example, helps companies get a hand-picked shortlist of vetted engineers within 48 hours, with talent from 30+ countries and 4–6 hours of timezone overlap. You can compare market benchmarks in software developer rates by country, review remote developer rates, or see how OctogleHire vets engineers.

Next steps

Build your hiring budget from the offer backward:

1. Start with the target salary band.
2. Add employer payroll taxes using current federal and state rules.
3. Add health insurance using your actual renewal rates, not a generic average.
4. Add retirement, bonus, equity, and paid-leave assumptions.
5. Add first-year recruiting, onboarding, laptop, security, and dev-tool costs.
6. Compare the fully loaded number with alternatives: US employee, US contractor, EOR hire, offshore contractor, or a vetted remote engineer through a platform such as OctogleHire.

For a typical US software engineer, if you only budget salary, you are short. If you budget 1.25x–1.45x salary, you are much closer to the real annual cost of hiring and retaining the role.
