Supervisor of Mechanics and Installers Salary in California: Pay by Experience, City & Take-Home

A first-line supervisor of mechanics, installers, and repairers in California earns a median of $93,660 a year, or about $45.03 an hour, according to the U.S. Bureau of Labor Statistics (2025). Most people in the role land between $72,910 and $120,050, with the bottom 10 percent near $56,720 and the top 10 percent above $154,820. That California median runs well ahead of the national figure.

How California pay compares to the national figure

California pays this role more than the country as a whole. The national median for first-line supervisors of mechanics, installers, and repairers is $79,860, per BLS OEWS 2025. California’s median of $93,660 sits $13,800 above that, a premium of roughly 17 percent. The state mean is higher still at $98,440, which tells you the upper tail of California pay pulls the average up past the midpoint.

That gap reflects two things at once. California carries higher wage floors and a denser concentration of the industries that need these supervisors, transit fleets, utilities, aerospace, refining, and data-center mechanical systems. It also carries a higher cost of living, so the raw premium does not translate one-for-one into spending power. The take-home section below works that math through federal tax, FICA, and California state tax so you can see what actually lands in the bank.

It helps to read the premium as a range rather than a single number. At the bottom of the scale, California’s 10th percentile of $56,720 still beats some states’ medians for the role outright. At the top, California’s 90th percentile of $154,820 is nearly double the national median of $79,860. So the state advantage is not evenly spread; it widens as you climb. A new supervisor sees a modest California bump over the national entry level, while a senior supervisor in a high-pay metro can be earning tens of thousands more than a same-title peer in a lower-cost state. The state mean of $98,440 landing $4,780 above the state median is the statistical fingerprint of that top-heavy distribution.

Supervisor of mechanics pay by experience in California

Pay in this role tracks experience, the size of the crew you run, and the criticality of the equipment. A new lead promoted off the tools starts near the 10th percentile. By the time you are running a shift or a department with budget and hiring authority, you move into the 75th and 90th percentiles. The percentile points below come straight from California OEWS data, so they describe the actual spread in the state, not a national curve.

The jump from median to the 75th percentile is $26,390, and from the 75th to the 90th it is another $34,770. That top step is where the role stops being a pay-grade promotion and starts being a management track, the people clearing $154,820 are typically running large fleets, multi-site maintenance, or specialized high-stakes systems where downtime is expensive.

Read from the other direction, the early-career math is just as clear. The 10th percentile of $56,720 and the 25th percentile of $72,910 are $16,190 apart, so the first promotion off the floor and into a real supervisory line tends to add roughly sixteen thousand dollars in California. From the 25th to the median is another $20,750. Those two steps, from $72,910 up to $93,660, are where most working supervisors spend their careers, and they are usually a function of years on the job, crew size, and how mission-critical the equipment is. The middle 50 percent of the role, the band from the 25th to the 75th percentile, runs from $72,910 to $120,050, a $47,140 spread. That is the realistic planning window for almost anyone in the title; the percentiles below and above it describe the entry door and the management ceiling.

One practical note on the hourly figures: the approximate hourly rates in the table assume a standard 2,080-hour work year. Many supervisors in transit, utilities, and heavy industry work overtime or carry on-call premiums, so actual annual earnings at a given hourly base can land higher than the straight multiplication suggests. The BLS percentiles already capture realized annual pay, which is why the median annual of $93,660 and the median hourly of $45.03 line up almost exactly at the standard-year assumption.

Supervisor of mechanics pay by California metro

Where you work inside California moves the number meaningfully. The Bay Area pays the most, and the inland and southern metros sit lower while still beating the national median. The table covers the five largest California metro areas by employment in this role, per BLS OEWS 2025.

San Francisco leads at $102,360, which is $17,280 above the San Diego median of $85,080, the widest in-state gap among these five. Los Angeles holds by far the most jobs at 17,470, more than the other four metros on the list would suggest from their medians alone, so it is the deepest market if you want options without leaving the state. Riverside-San Bernardino and Sacramento sit close together in the high $80,000s to low $90,000s, and both pair a lower headline number with housing costs that are gentler than the coastal metros, which matters once you net everything out.

The employment counts tell their own story about where the work actually is. Los Angeles at 17,470 jobs holds more than the other four metros on this list combined would, and it is almost three times the size of the second-largest market, San Francisco at 6,130. Riverside-San Bernardino-Ontario follows at 5,660, San Diego at 4,240, and Sacramento at 2,930. Together these five metros account for 36,430 of the 51,670 supervisor jobs in California, roughly 71 percent of the statewide total, which means the remaining 15,240 are spread across smaller metros and rural areas like the Central Valley, the Central Coast, and the far north.

For a job seeker, the read is straightforward. San Francisco offers the highest median but a relatively small number of seats. Los Angeles offers slightly lower median pay, $93,870 against the Bay Area’s $102,360, a difference of $8,490, but vastly more openings and far more room to switch employers without relocating. The inland metros trade headline pay for cost of living, and Sacramento in particular pairs a $92,680 median, essentially level with the statewide $93,660, against housing that costs less than the coastal markets. That combination can leave more in your pocket each month than a higher gross in San Francisco once rent or a mortgage comes out.

Take-home pay after California taxes

The headline salary is not what you keep. California layers a progressive state income tax on top of federal tax and FICA, so the effective rate climbs as you move up the percentiles. The table below shows the full breakdown at each career stage using a 2026 tax-year estimate, federal income tax, FICA (Social Security and Medicare), California state tax, and what is left as net annual and net monthly pay.

At the median, a California supervisor keeps $69,538 of a $93,660 salary, an effective tax bite of about 25.8 percent. The state portion alone is $4,738 at that point. By the 90th percentile the effective rate reaches 31.4 percent, and California state tax climbs to $10,425, more than double the median’s state bill on roughly 65 percent more gross pay. That is the progressive structure doing its work.

The effective rate climbs cleanly with income across every stage. An entry-level supervisor at $56,720 pays about 19.0 percent all-in and keeps $45,965, or $3,830 a month. At the median the rate is 25.8 percent. At the 75th percentile of $120,050 it reaches 28.7 percent, leaving $85,615 net, or $7,135 a month. At the senior 90th percentile of $154,820 the rate hits 31.4 percent, with $106,147 net, or $8,846 a month. So between entry and senior pay, the gross roughly triples while the net a bit less than triples, because each added dollar at the top is taxed harder than the first dollars at the bottom. The federal line moves the most in absolute terms, from $4,768 at entry to $26,404 at the senior level, while FICA rises in a near-straight line from $4,339 to $11,844 because it is a flat-rate payroll tax up to the Social Security wage cap.

Here is the comparison an AI summary will not give you. Take that same $93,660 median and earn it in Texas instead, a state with no personal income tax. The California worker nets $69,538. The Texas worker nets $74,276 on the identical gross, because California state tax of $4,738 never comes out. That is a gap of $4,738 a year, money that stays in the Texas paycheck purely because of where the work is done.

But the net figure on its own is only half the decision. The number that actually matters is net pay minus local housing. California’s coastal metros carry some of the highest rents and home prices in the country, so a San Francisco supervisor netting more in raw dollars can still have less left over after the mortgage or lease than a Texas peer keeping $74,276 against cheaper housing. Before you weigh an offer or a move, subtract your real housing cost from the net monthly figure in the table, that residual is your true comparison number. Many people in this role also run the year-end math with tax-preparation software like TurboTax to confirm withholding lines up with what they actually owe California. You can also model any salary against your own deductions in the California paycheck calculator.

To put the housing framing in concrete terms, work from the net monthly figures. A median earner takes home $5,795 a month. A common budgeting rule keeps housing under a third of net pay, which would cap rent or a mortgage payment near $1,930 a month at the median, a number that is tight in San Francisco and Los Angeles and more workable in Sacramento or Riverside-San Bernardino. The $4,738 California-versus-Texas gap, spread across twelve months, is about $395 a month. If your housing cost in a Texas market runs more than $395 a month below a comparable California market, the after-housing math can favor Texas outright even before the income-tax difference. If California housing is closer to par, the higher gross pay in metros like San Francisco can still come out ahead. The point is to run your own two numbers, net monthly and local housing, rather than comparing headline salaries.

How to earn more as a mechanics supervisor in California

The spread between the median ($93,660) and the 90th percentile ($154,820) is $61,160, so there is real room to move. The levers that close that gap in California are specific.

• Move toward the Bay Area or a high-pay industry. San Francisco’s $102,360 median is $8,700 above the state median. Aerospace, refining, utilities, and transit fleets cluster the higher-paying supervisory jobs.
• Take on fleet size and budget authority. The 75th and 90th percentile jobs come with crews, capital budgets, and uptime accountability. Ask for the larger department, not just the title.
• Stack technical certifications that justify a premium. ASE Master and EVT credentials, EPA 608 for refrigerant systems, OSHA 30, and PMP for project-level maintenance work all signal readiness for senior roles. Self-paced management and operations courses through a provider like Coursera can fill the supervisory and budgeting gaps that hold technical leads back from the department-head step.
• Specialize in high-consequence systems. Supervisors over equipment where downtime costs the most, power generation, data-center cooling, rail, and heavy industrial lines, sit nearer the top of the range.
• Document your loss and safety record. California employers pay for supervisors who keep injury rates and equipment failures down. Bring the numbers to the review.

Put a dollar value on each step so the target is concrete. Moving from the state median of $93,660 to the 75th percentile of $120,050 is a $26,390 raise, the kind that typically comes from a bigger crew or a more critical fleet. Reaching the 90th percentile at $154,820 adds another $34,770 on top of that. Even a metro switch matters: trading the San Diego median of $85,080 for the San Francisco median of $102,360 is worth $17,280 in gross pay for the same title. None of these moves are guaranteed, but they are the specific, data-backed paths that separate a typical California supervisor from a top-decile one, and most of them are some combination of where you work, how much you run, and which credentials you hold.

Job outlook for mechanics supervisors in California

California employs 51,670 first-line supervisors of mechanics, installers, and repairers, per BLS OEWS 2025, the largest state workforce in this occupation. That depth matters: it means turnover, retirements, and fleet growth keep openings flowing, and you can change employers or metros without leaving the state. Los Angeles alone accounts for 17,470 of those jobs, and the five metros in the table above hold 36,430 between them. Demand follows the equipment base, transit, utilities, aerospace, and logistics, all of which keep large maintenance crews that need supervisors.

Related and higher-paying roles in California

Two adjacent supervisory and inspection roles are worth a side-by-side look in California, because both pay less than a first-line mechanics superviser here. A Production and Operating Supervisor earns a California median of $76,840, which is $16,820 LESS than a first-line mechanics supervisor in California. An Inspector, Tester, and Sorter earns a California median of $54,300, which is $39,360 LESS than this role. In other words, the mechanics-supervisor track sits at the higher end of this cluster in the state, and stepping into it from inspection or general production supervision is a clear pay move.
