Missouri metro-by-metro prices
1 of the 6 metros sit above the statewide midpoint of $2,600, and the top-to-bottom gap is 14%. Each row prices the default size with that metro's own BLS wages and BEA price levels, so the gap between rows is real local variation rather than a flat markup.

Missouri labor market for attic insulation
Statewide wages come from BLS's state-level estimates, which blend big cities with small towns and rural areas. 2 trades drive the labor line for this job, and the weighted ratio against the national wage level is 1.15 for Missouri.
Insulation workers, floor, ceiling and wall (47-2131), 80% of the weighting: a median of $26.94 an hour, 14% above the US median of $23.62. The middle half of them earn between $23.01 and $36.27 an hour. About 830 work in the state. That is 2.8 per 10,000 jobs, compared with 2.9 nationally, so the supply of crews looks typical.
Construction laborers (47-2061), 20% of the weighting: a median of $27.28 an hour, 20% above the US median of $22.66. The middle half of them earn between $21.93 and $37.30 an hour. About 17,050 work in the state. That is 58.1 per 10,000 jobs, compared with 70.5 nationally, so expect fewer local crews to bid.
A crew paid at the 75th percentile for insulation workers, floor, ceiling and wall ($36.27 an hour) would add about $280 to the statewide midpoint; one at the 25th percentile ($23.01) would take off about $120. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 2,936,050 jobs across Missouri (May 2025), which is 1.9% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |

| Insulation workers, floor, ceiling and wall (47-2131) | 80% | $23.01 | $26.94 | $36.27 | $23.62 | 1.14 | state |
