Formula used
Working hours = (estimated days × hours per day) + overtime hours.
Base rental cost depends on rental basis. Hourly uses rate × hours. Daily, weekly, and monthly convert to a day rate, then add overtime using an hourly equivalent and multiplier.
Standby cost = standby hours × hourly rate × standby billing percentage.
Discount applies to rental, standby, and wear allowance totals.
Fuel surcharge and insurance apply after discount, then operator and fixed fees are added. Contingency is applied before tax.
Grand total = (subtotal + contingency) + tax. Optional cost per ton = grand total ÷ (production rate × working hours).

Notes for project teams
- Confirm whether standby is billable and at what percentage.
- Check if wear items are included or charged separately.
- Use actual haul distance and include round trip if required.
- Apply the same tax and insurance basis used in your contract.
- Use cost per ton only with measured production assumptions.
Crusher bucket rental guidance
1) Rental scope and typical applications
Crusher buckets are often hired for trench backfill reuse, road subbase preparation, demolition clean-up, and onsite recycling. Many contractors target short, high-impact campaigns, such as five to fifteen working days, to avoid double handling and disposal trips.
2) Key cost drivers in crusher bucket hire
The biggest drivers are rental basis, planned hours, and utilization. A daily contract can look inexpensive until overtime, standby, and operator time are added. Standby billing frequently ranges from 25% to 75% of the normal hour rate, depending on contract terms.
3) Rate benchmarks and market ranges
Rates vary by bucket size, carrier compatibility, and material hardness. For budgeting, many teams see hourly hire in the 80 to 180 range, daily in the 600 to 1,200 range, and weekly in the 3,500 to 7,500 range. Add-ons can shift totals by 10% to 35%.
4) Shift planning and utilization metrics
Crusher output is driven by feed consistency and operator technique. Production assumptions commonly fall between 15 and 60 tons per hour for mixed site material, with higher outputs on uniform, non-rebar concrete. Use the optional cost per ton result to test scenarios and validate payback. For concrete recycling, many crews aim for 0–40 mm product using adjustable jaws, and check rebar separation time to protect schedule.
5) Wear parts and maintenance allowances
Wear costs rise with abrasive rock and steel contamination. Many site budgets carry a wear allowance of 8 to 20 per working hour for teeth and liners, while some suppliers bundle wear into a higher base rate. Record hours separately from standby to keep comparisons fair.
6) Transport, mobilization, and site logistics
Mobilization, demobilization, and haulage can dominate short hires. A realistic transport rate can range from 0.5 to 2.5 per kilometer, and some suppliers charge round trip distance. Include lifting access, laydown space, and a safe loading zone to prevent delays. Allow 30 to 90 minutes for hookup, greasing, and test runs each shift change.
7) Risk allowances, insurance, and compliance
Typical contingency allowances for temporary works and productivity risk are 2% to 8%. Insurance may be billed as a flat fee or a percentage of the discounted subtotal, often 1% to 3%. Apply your project tax and document the basis for audit-ready records.
8) Reporting, approvals, and record keeping
Use the breakdown to support approvals and client reimbursements. A clear split between rental, operator, transport, and surcharges helps avoid disputes. Export CSV for cost tracking and PDF for site files, daily reports, and package sign-off submissions.
FAQs
1) Should I choose hourly or daily billing?
Choose hourly for short, controlled tasks and predictable access. Choose daily when you expect steady utilization across the shift and want simpler administration. Compare both with overtime and standby included.
2) How do I estimate standby correctly?
Enter standby days and the standby billing percentage from your contract. Standby is typically charged at a reduced rate when the bucket is on site but not producing, such as weather, access, or plant downtime.
3) What is a reasonable fuel surcharge value?
Fuel surcharges commonly fall between 3% and 8% of the discounted subtotal, but some suppliers include fuel within the base rate. Use the contract wording to decide whether to apply a surcharge at all.
4) Do I include the excavator in this calculator?
This calculator focuses on the crusher bucket package. If the excavator is hired separately, add the excavator cost to your project estimate. If the supplier provides both, include the combined rate as the base rate.
5) How can I use cost per ton safely?
Use measured production from similar work or pilot trials. Enter a conservative tons per hour figure and confirm working hours exclude standby. This avoids overstating output and understating the effective unit cost.
6) Where should discounts be applied?
Discounts usually apply to rental and wear allowances, and sometimes to standby if negotiated. Fixed fees like mobilization and transport are often excluded. Apply discounts only where your quotation or contract states they are allowed.
7) Why is my total higher than the base rate times duration?
Totals rise when overtime, operator time, transport, mobilization, insurance, fuel surcharges, contingency, and tax are included. The breakdown is designed to show each contributor so you can adjust assumptions or negotiate terms.
