Direct Answer: Factoring diamond blade consumption into concrete sawing bids requires calculating cost-per-foot: Cost-Per-Foot = (Blade Purchase Price / Expected Linear Feet Cut) + (Labor Rate / Feet Per Hour). For example, a 14" blade costing $300 that cuts 1,500 linear feet of cured concrete yields a blade cost of $0.20 per foot. Always adjust wear estimates up by 25% when bidding hard river rock or heavy rebar jobs.
