What this figure cannot tell you
It covers people EMPLOYED in this occupation. Anyone who trained for it and was never hired is not in the median above, and neither is anyone doing the work self-employed. No verified count of qualified people exists for this occupation, so this page shows none rather than an estimate. Why that matters · The occupations where we could source it
Who this suits
Stationary Engineers and Boiler Operators pays $78,620 at the midpoint, 57% above the $50,020 national figure. Premiums that size are rationed by something; find out what before the salary does your thinking for you.
28,250 people do this work nationally. That is the size at which Stationary Engineers and Boiler Operators becomes a career rather than a post — enough employers in a normal city that leaving one of them is a decision rather than a crisis.
These roles suit people who take a licence or a certification seriously and are comfortable being trusted with a system most people never think about.
How long it takes to become one of the 28,250 people doing this is not something we have a source for. BLS counts and pays them; it does not record how they got there, and we would rather say so than guess.
Who should not do this
$63,160 to $101,150 — 1.6x, or $3,165 a month between the quarters. An unremarkable spread, which means the useful planning number for Stationary Engineers and Boiler Operators is the bottom of it rather than the middle.
At $63,160, or $30.36 an hour, the 25th percentile sits $13,140 above the $50,020 the typical American job pays. Occupations with floors this high almost always have a requirement holding them there.
Avoid it if you would not want the responsibility of being the person on shift when the system goes out of range.
There is no failure rate on this page because there is nothing honest to divide by. BLS counted 28,250 people employed as Stationary Engineers and Boiler Operators; it did not count the people who trained for it and are doing something else, and a rate built without that denominator would be a number we made up.
What the spread tells you
1.6x between $63,160 and $101,150 is the ordinary shape of an occupation where experience and region both matter and neither dominates. $78,620 is a fair expectation by mid-career, not on day one.
In cash terms the middle half of Stationary Engineers and Boiler Operators runs $63,160 to $101,150 — $37,990 a year between the 25th and 75th percentiles, against a midpoint of $78,620.
Getting to $101,150, the 75th percentile, is worth $22,530 a year more than the $78,620 midpoint and $37,990 more than the $63,160 a quarter of Stationary Engineers and Boiler Operators settle for.
$22,530 separates $78,620 from the $101,150 top quarter, while only $15,460 separates it from $63,160. The range leans upward, which means the middle of Stationary Engineers and Boiler Operators has more room above it than a symmetric reading of the median would suggest.
Converted to an hourly rate over a full-time year: $30.36 at the bottom quarter, $37.79 at the midpoint, $48.62 at the top quarter. The typical American job works out at $24.04 on the same basis.
What these figures are, and what they are not
Employers reported these wages for people already working as Stationary Engineers and Boiler Operators. The self-employed are excluded, so $78,620 does not describe an independent doing the same work.
With no unpaid-hours or cost data for Stationary Engineers and Boiler Operators, the hourly figure is $78,620 over a 2,080-hour year — a unit conversion, not an adjustment.
