Diesel Mechanic vs Machinist
Diesel Mechanics earn a national median of $64,435 versus $57,590 for Machinists, a gap of $6,845 per 2024 BLS Occupational Employment and Wage Statistics. Diesel Mechanics have posted +5% 5-year wage growth versus +-1% for Machinists.
How These Trades Stack Up
Diesel Mechanics out-earn Machinists on national median by $6,845 — $64,435 versus $57,590, or about 12% more. That gap reflects differences in apprenticeship length, certification requirements, industry concentration, and union footprint between the two trades.
Diesel Mechanics have grown faster — +5% over five years versus +-1% for Machinists. Sustained growth gaps of this size can compound meaningfully over a 20-30 year career, so workers comparing the two trades should weigh growth alongside the headline median.
Diesel Mechanics typically complete a 3-year apprenticeship while Machinists require 4 years. The longer pathway usually translates into higher journeyman pay and stronger licensure protection, but it also delays full earnings; the shorter pathway delivers faster income at typically lower medians.

How These Numbers Are Calculated
All wage figures come from the U.S. Bureau of Labor Statistics Occupational Employment and Wage Statistics (2024) release at bls.gov/oes. National medians are the BLS-published median wages for the trade's Standard Occupational Classification (SOC) code; metropolitan medians come from the same OEWS release at the metropolitan statistical area level. Five-year wage growth compares the current OEWS median to the same series five releases prior, expressed as a percent change. The Trade Pay Score weights raw pay (30%), wage growth (25%), employment depth (25%), and cost-of-living-adjusted purchasing power (20%) into a single 0-100 grade — read the full methodology.
Forward-looking employment projections through 2032 for both trades are published in the BLS Occupational Outlook Handbook at bls.gov/ooh. Apprenticeship pathway detail comes from the U.S. Department of Labor's apprenticeship.gov registry. All three are public-domain federal data sources.

Comparing entity A and entity B on U.S. skilled-trade wage data requires lining up the underlying the BLS Occupational Employment and Wage Statistics (OEWS) survey data side by side. The table above runs the comparison on the canonical fields; the narrative below identifies the factor or factors that drive the most meaningful difference between the two.
Practical use of the comparison: read the data above, then drill into the individual entity A and entity B detail pages for the underlying breakdown. A pairwise comparison answers the relative question; the per-entity pages answer the absolute question.
