Examples illustrate typical inputs and rounded outputs for planning.
Jobsite equipment can draw a short surge above its running load. Pumps, compressors, and some welders may need 2–4× starting power. Size the generator with headroom and try to operate around 60–80% average load to keep voltage stable and avoid nuisance trips.
Rental days describe billing, not consumption. Estimate runtime by entering operating hours per day and a realistic load factor. Example: 8 hours/day at 0.60 load for 5 days equals 24 “full-load hours.” This supports better fueling plans and reduces surprise refueling during overtime.
Delivery is often underestimated on constrained sites. Use distance, rate, and minimum fee, then decide whether pickup is included. One-way delivery fits contracts where the supplier collects the unit; otherwise, model a round trip. Include access limits, lifts, and restricted routes that can add handling costs.
Generators rarely connect directly to every tool. Cable sets, distribution boxes, grounding kits, and transfer switches route power safely and reduce downtime. Match cable lengths to work zones and ensure protective devices suit temporary panels. Including accessories early improves budget accuracy for lighting, pumps, and small plant.
Temporary power sits in high-traffic areas, so risk pricing matters. Insurance and damage waivers are commonly calculated as a percentage of the running subtotal. Confirm coverage requirements, document serial numbers, and keep inspection records for cords and panels. Good documentation reduces disputes and supports safety reviews.
If fuel is excluded, enter consumption (L/hour) and fuel price to estimate liters and cost. Use a load factor that matches duty cycles; even light loads still burn fuel. Record assumptions in your report, and plan compliant storage, spill control, and refueling procedures for nights and remote locations.
Rates often drop when rentals shift from daily to weekly or monthly terms. Apply the discount field to model negotiated pricing, then compare cost per day with options such as sharing a larger unit. Verify what the rate includes—delivery, basic cables, fuel service, and standby coverage—to avoid change orders.
Before ordering, check demand, noise limits, cable runs, and refueling access. Confirm whether ground-fault protection, weatherproof connections, or distribution boards are required. A short review prevents rework, reduces delays, and keeps the temporary electrical setup consistent as tasks and crews rotate.
Add the running watts of tools, then include starting surges. Convert to kW and add headroom for future loads. Oversizing slightly can prevent nuisance trips and delays.
Generators rarely run at full load continuously. Load factor represents average utilization and scales fuel use. A realistic factor produces a closer estimate than assuming constant maximum demand.
If the rental company includes pickup, charge delivery once. If pickup is billed separately, treat delivery as a round trip. This calculator lets you switch between both models.
They can. Distribution gear, transfer switches, and lighting add daily charges and improve safety and convenience. Include them early to avoid underestimating the true delivered cost.
Ask the rental provider for a consumption chart at different loads. If you leave it blank, the calculator will not guess liters. You can still estimate rental fees without fuel.
Requirements vary by contractor, project owner, and rental agreement. Some rentals mandate minimum coverage or offer waivers. Use the percentage fields to match your contract terms.
Enter your negotiated daily equivalent in the override field. Then keep the rental days accurate. The output will reflect your effective rate and help compare alternative durations.
Plan rentals carefully to keep your site powered always.
