⚡The short answer: salary times 1.25 to 1.4, then keep counting
The salary is the number everyone quotes and the number nobody actually pays. Between employer payroll taxes, health benefits, retirement contributions, equipment, software licences and workspace, a US employee costs a quarter to two-fifths more than the salary line. That is the 1.25 to 1.4 loaded multiplier, and it is the floor, not the total — it excludes what you spent recruiting the person, the productivity ramp after they start, and the amortized cost of replacing the person who left before them.
Why a range instead of one number? Because benefits richness, state taxes and work-from-anywhere stipends genuinely vary. A lean startup with a high-deductible health plan and no 401(k) match sits near 1.25. A company with family health coverage, a real match, generous equipment and an office in a high-tax state approaches 1.4. Anyone quoting you a single universal multiplier has not run payroll.
The table below is the whole article in one view, using a representative $180,000 base salary. Every line is expanded in its own section, with the ranges labelled as what they are: observed market ranges as of writing, not a published survey.

🌎Salary bands by US metro
Senior engineer pay in the US is not one market; it is several, layered by metro and by company type. The bands below are labelled observed ranges for senior individual-contributor engineers (five-plus years, able to own systems end to end) as of writing. They blend base salary only — equity and bonus sit on top at companies that pay them. Verify current numbers before budgeting; these move year to year and the top of each band moves fastest.
Two structural notes matter more than any number. First, remote work compressed the geography discount without eliminating it: fully remote roles at US companies typically price at a national band that sits between the coastal metros and everywhere else. Second, the spread within a metro is wider than the spread between metros — a senior engineer at a top-tier tech company in Austin can out-earn one at a non-tech enterprise in San Francisco. Company tier moves pay more than zip code does.
Use the table as a budgeting anchor, not an offer sheet. The practical workflow: identify which band your candidate pool actually lives in (usually set by remote policy, not your office), budget from the middle of that band, and hold the top of the range in reserve for the candidate who is genuinely worth it. Offers built from stale salary data are the most common way senior searches stall in month three.
| Market | Senior base salary (labelled range) | Fully loaded planning figure (× 1.25–1.4) |
|---|---|---|
| San Francisco Bay Area | $180,000 – $260,000+ | $225,000 – $360,000+ |
| New York City | $170,000 – $240,000 | $215,000 – $335,000 |
| Seattle | $165,000 – $235,000 | $205,000 – $330,000 |
| Austin / Denver / Boston | $150,000 – $210,000 | $190,000 – $295,000 |
| Chicago / Atlanta / Dallas | $140,000 – $195,000 | $175,000 – $275,000 |
| Remote (national band) | $140,000 – $200,000 | $175,000 – $280,000 |
| Smaller metros / low-cost states | $120,000 – $170,000 | $150,000 – $240,000 |
The metro table decides far less than founders expect. What decides the salary conversation is company tier, interview rigor and whether the role is remote. Budget against the band of companies you are actually competing with for candidates — not the city on your office lease.
🧾The 1.25 to 1.4 multiplier, line by line
The multiplier is not overhead ideology; it is six specific lines that show up in every payroll run. Walking through them on a $180,000 salary makes the range concrete and shows where your own company will sit inside it.
The wide lines deserve the most attention, because that is where companies fool themselves. Health benefits are the big one: the difference between covering an individual on a high-deductible plan and covering a family on a low-deductible plan can exceed $12,000 a year for the same engineer. Workspace swings nearly as much — a downtown office seat carrying its share of rent, utilities and perks can pass $10,000 a year, while a remote stipend policy might cost $2,000.
Two traps to avoid when you build your own number. First, do not forget the quiet lines: state paid-leave programs, life and disability insurance, learning budgets and the amortized laptop are small alone and meaningful together. Second, resist using the low end of every range at once — model the benefits posture you actually offer. A multiplier assembled from best-case assumptions produces a budget that is wrong in exactly one direction.
| Line | What it is | Labelled annual cost |
|---|---|---|
| Employer FICA | 7.65% of wages for Social Security and Medicare (Social Security capped at the wage base, so slightly less at senior salaries) | $13,000 – $14,500 |
| State & unemployment taxes | State unemployment, disability and paid-leave programs; varies widely by state | $1,000 – $5,000 |
| Health benefits | Employer share of medical, dental, vision; family coverage pushes the top of the range | $6,000 – $20,000+ |
| 401(k) match | Common matches run 3–6% of salary; some companies offer none | $0 – $10,800 |
| Equipment & software | Laptop amortized over 3 years, monitors, SaaS licences, dev tooling, AI assistants | $3,000 – $8,000 |
| Workspace | Office seat cost, or a remote stipend plus home-office allowance | $0 – $12,000 |
Build the multiplier from the benefits posture you actually offer, not the low end of every range. A multiplier assembled from best-case assumptions produces a budget that is wrong in exactly one direction — and engineering headcount is the worst line on the budget to be optimistic about.
🔎Recruiting: the cost nobody amortizes
Hiring a senior engineer in the US costs real money before the first day of work. An external recruiter typically charges 15 to 25 percent of first-year base salary — $27,000 to $45,000 on a $180,000 hire. Internal recruiting is not free either: a realistic tally is forty to eighty hours of engineering and leadership time across sourcing, screening, interviews and debriefs, which at loaded senior rates is $5,000 to $15,000 of diverted capacity, plus job boards, sourcing tools and referral bonuses.
Then there is the cost of the empty seat. Senior searches routinely run two to four months. If the role existed to build revenue-generating or cost-saving work, every month open has an opportunity cost that frequently exceeds the recruiter fee. This is the line that makes "we will just take our time hiring" an expensive sentence.
The honest way to budget is to amortize: total recruiting cost divided by expected tenure. A $35,000 all-in recruiting cost over an expected three-year tenure is roughly $12,000 per year of the seat being occupied — a permanent add-on to the loaded salary for as long as tenure stays short. Which is why the next section, attrition, is the multiplier on the multiplier.
🔁Attrition and replacement: the multiplier on the multiplier
Replacement is the largest hidden line in engineering budgets, and the one finance models rarely carry. When a senior engineer leaves, you pay the recruiting cost again, the empty-seat cost again, and the ramp cost again — plus a knowledge-transfer tax, because a departing senior takes system context that the replacement rebuilds over months. Conservative industry estimates place total replacement cost for senior technical staff between half and one-and-a-half times annual salary; for a $180,000 engineer that is $90,000 to $270,000 per departure, most of it invisible because it arrives as slow delivery rather than an invoice.
You cannot budget that per event, but you can budget it as a reserve. If your expected tenure for senior engineers is three years, one third of a replacement cost lands on every seat every year — call it $30,000 to $60,000 annualized at the conservative end, or $10,000 to $30,000 if your retention is genuinely strong. Companies with weak retention are not paying less for engineering; they are paying the replacement tax instead of salaries, and getting worse output for it.
The implication for planning is uncomfortable but useful: retention spending (real raises, good management, interesting work) is almost always cheaper than replacement. A $15,000 retention raise is a rounding error next to a $150,000 departure.
⚖️The honest comparison: employee vs agency vs dedicated team
None of this means you should not hire — it means you should hire with open eyes and compare against the real alternatives at their real prices. An agency builds a defined scope for a project price; at US blended rates of $100 to $175 per hour (labelled ranges as of writing), a senior-heavy project team delivering a six-month build often lands between $150,000 and $400,000 all-in, with management and QA bundled. A dedicated team rents you named engineers monthly; senior dedicated engineers through a firm like ours — US-led from Edmonton with senior talent in Chandigarh — typically run $8,000 to $18,000 per month per engineer depending on seniority and location mix, management layer included.
Converted crudely to annual terms, a dedicated senior engineer at $12,000 per month is $144,000 per year — below the loaded cost of a US employee at a coastal salary. That comparison is real but incomplete in both directions. The employee accumulates context, stays for years, and builds the hiring culture; the dedicated engineer arrives managed, starts in weeks, and can be scaled down without a layoff. The right question is not which is cheaper per year but which fits the shape of the work: permanent core team building favors employees; defined builds and flexible capacity favor agencies and dedicated teams.
A pattern we see work well at growth stage: a small core of employed senior engineers owning architecture and product context, with a dedicated team carrying the execution load around them. It caps the fixed payroll, keeps the knowledge in-house, and flexes with the roadmap. It fails only when companies skip the internal core entirely and let a vendor hold all the context.
See dedicated senior engineers and team optionsHow the dedicated team cost model works
| Dimension | US employee (senior) | Dedicated engineer (blended team) | Agency project team |
|---|---|---|---|
| Real annual cost | $240,000 – $290,000 realistic planning figure | $96,000 – $216,000 (labelled monthly × 12) | Scoped per project, not per year |
| Time to productive | 2–4 months search + 1–3 months ramp | 2–4 weeks typically | Weeks; team arrives pre-formed |
| Management overhead | Yours entirely | Shared with the vendor | Bundled into the engagement |
| Context retention | Highest — compounds for years | Good with stable allocation | Lowest — ends with the project |
| Flexibility | Low — layoffs are slow and costly | High — scale monthly | High — ends at delivery |
| Best for | Core product, long horizon, culture | Sustained execution capacity | Defined scope, fixed outcome |
🎯When each option actually wins
Hire the employee when the work is core, permanent and compounding: the engineer who will own your payments system for three years should be yours. Use a dedicated team when the work is real but the horizon is uncertain — a product line that might scale or might be cut, a backlog that exceeds the core team by two times for the next year. Use an agency when the work has an end: a build, a migration, a launch, where a pre-formed team with its own management finishes faster than a team you assemble.
The mistake to avoid is choosing on sticker price alone. An employee who looks expensive against a dedicated engineer is buying context retention and culture; a dedicated engineer who looks cheap against an employee is renting flexibility you may not need. Price the option against the shape of the next three years of work, and the right answer usually becomes obvious.
And whichever route you take, budget with the loaded number, not the salary. The companies that get engineering finance right are not the ones that found cheaper engineers; they are the ones that stopped being surprised by the other 40 percent.
