Blasting costs are often misunderstood because they depend on how quickly your abrasive is consumed. This calculator uses pot size, refill time, and abrasive density to estimate hourly consumption, then combines that with abrasive cost, disposal, labor, and equipment to show a realistic cost per square foot. By focusing only on actual usage, this tool gives you a straightforward way to measure and compare blasting efficiency.
Abrasive Cost Per Square Foot Calculator
COST PER SQUARE FOOT CALCULATOR
Estimate blasting cost/ft² using either calculated abrasive consumption or direct lbs/hr input.
Formula: (A(B + C) + D + E) / X. A = abrasive consumption in lbs/hr, B = abrasive price $/lb, C = disposal cost converted to $/lb, D = labor $/hr, E = equipment $/hr, X = ft²/hr.
Abrasive type / default price
Choose type, related defaults auto-fill.
Abrasive consumption input method
Use direct lbs/hr for Mega Blast Pots or multi-outlet setups.
Blast pot size
Used only in calculated mode.

Abrasive consumption used
0 lbs/hr
Calculated from blast pot setup.
Disclaimer: This estimate is based on continuous production at the given rate. Real-world costs vary with mobilization, setup, access, containment, weather, downtime, and waste handling requirements. Direct lbs/hr mode is useful when calculated pot-refill logic does not reflect multi-outlet or Mega Blast Pot behavior.
