Estimate by industry

How the estimate is built

Uses the published Massachusetts manual class rates from Circular Letter 2432. The calculator uses class-rate benchmarks only and does not add every minimum premium, expense constant, terrorism charge or other policy-level adjustment. HVAC uses sheet metal/heating-air-conditioning class 5538. Restaurant uses 9079. Pool cleaning uses janitorial class 9014 as the closest cleaning-services proxy. Carpentry and concrete use equal-weight blends.
