45 lost minutes a day across a 5-person crew burns $71,562/yr — a full salary spent standing around. Downtime is invisible daily and enormous annually.
Downtime never looks expensive at 9 a.m. — it is 45 minutes of waiting on materials, an unclear drawing, a missing inspection. Annualized, it is a salary: five crew at $55/hr loaded losing 45 minutes a day burns $51,562 of labor plus $20,000 of idle equipment across 250 workdays — $71,562, or $1,376 every single week. The fixes are logistics, not speed: a 15-minute morning huddle, materials staged the night before, a two-week lookahead, and one decision channel. This calculator converts your idle minutes into the annual number that justifies them — and the number that belongs inside your labor rate.
Contractors use it before blaming the bid: 45 idle minutes a day across a 5-person crew burns $71,562/yr — a full salary spent standing around, fixable with a 15-minute huddle and next-day staging.
Jobsite studies keep finding the same five leaks, and none of them are laziness. Materials logistics: the delivery that arrives at 11, the order that is short two items, the part nobody staged — crews stand while the supply chain improvises; next-day staging (tonight, before anyone leaves) is the fix. Information gaps: the task starts without complete scope, drawings, or a decision — the crew waits while the answer drives to the site; the morning huddle names these before they cost hours. Trade stacking and inspections: waiting on the previous trade or the inspector — a two-week lookahead schedule shared with subs and the inspector booked days ahead collapses this. Tool and equipment trips: the run back to the shop for the thing that should be on the truck — truck stock lists are a one-time project that pays forever. And rework: miscommunication redone is downtime twice — the work AND the undo. The pattern: every leak is management, not labor — which is why the fix budget is tiny against the loss. Track it with a simple daily field log (hours paid vs hours productive, by cause) for two weeks; the crew that logs it usually finds the number is worse than this calculator's default.
Wages lie about cost; the loaded rate tells the truth. The $38/hr carpenter costs you $50–60/hr once payroll taxes (7.65% FICA plus unemployment), workers comp (class rates of $5–15 per $100 in the trades — see the workers comp calculator), benefits, PTO, and non-billable time stack on — the labor-burden calculator builds yours line by line. Using the loaded rate for downtime matters because idle time burns the FULL stack: the comp premium and payroll taxes run whether the crew is framing or waiting. The second-order effect most shops miss: downtime belongs inside your billing rate. If bids assume 100% productive hours but field logs show 87%, every estimate is under-priced by 13 points — you are bidding the crew you wish you had. Two ways to fix it: raise the productive-hours assumption by actually managing downtime (the huddle, the staging), or price the real number into the labor rate — either way this calculator is the measurement. The shops that outbid you profitably are not paying less for labor; they are wasting less of it.
Embarrassingly small — which is the point. The 15-minute morning huddle costs about $69/day on a five-person crew at $55 loaded (15 minutes × 5 × $55) — call it $17,000/yr against a $71,000 loss; if it reclaims even a third of the idle time it returns 2:1, and well-run huddles reclaim more. Next-day staging is supervisor time, not crew time: 30 minutes of a lead's evening against tomorrow morning's first hour of five. The two-week lookahead is a whiteboard and a Friday habit; the superintendent software versions (Buildertrend, Fieldwire, even a shared spreadsheet) cost $100–400/mo. Decision-channel discipline — one person empowered to answer crew questions in minutes — costs a phone call culture, not money. The equipment side: idle iron is priced at rental-equivalent rates ($80–300/day for the machines that matter), so moving the excavator to the next task or off-renting it between phases is pure capture. Total realistic program: under $25,000/yr of management time and software against a $71,562 leak, before counting the schedule compression that gets crews to the next job sooner. The barrier is never cost — it is that downtime is invisible until someone annualizes it. This calculator is the someone.
