Formula used
1) Base rental cost
Base cost = Rate × Billable units × Quantity. Billable units follow your selected billing mode and any minimum billable hours or days.
2) Standby cost
Standby cost = Daily equivalent rate × Standby percent × Standby days × Quantity. Daily equivalent is derived from daily, weekly, or 28-day monthly rates.
3) Delivery and logistics
Per-km delivery = 2 × Distance × Per-km rate + Mobilization + Demobilization. Flat delivery uses the flat amount instead of distance pricing.
4) Operator and overtime
Operator cost combines normal time plus overtime. Overtime uses an overtime multiplier applied to the operator hourly equivalent.
5) Surcharges, discount, and tax
Fuel, insurance, and waiver are added next. Discount reduces the running total, then tax applies to the discounted amount for the final grand total.

Rental estimating guide for pneumatic tire rollers
1) Why pneumatic tire rollers matter
Pneumatic tire rollers deliver kneading action and broad contact pressure, helping seal asphalt lifts and improve density. They are commonly used after breakdown rolling to tighten joints, close surface voids, and reduce permeability on highways, urban paving, and industrial yards.
2) Typical rental cost drivers
Rental pricing is quoted by hour, day, week, or a 28-day month. Costs vary with roller weight class, ballast requirements, tire count, maintenance condition, and local demand. This calculator separates the base rate from delivery, standby, operator time, and project surcharges. For planning, track utilization: a roller billed daily but used only six hours has a higher effective hourly cost.
3) Choosing the right billing mode
Hourly billing fits short patching, lane closures, or night shifts, while daily billing suits small paving programs. Weekly and monthly rates usually reduce the effective day cost for longer schedules. Switch modes to compare options without rebuilding your estimate or spreadsheet.
4) Minimum billing and standby days
Suppliers often apply minimum billable hours or minimum days even when production ends early. Standby is a discounted charge during weather delays, access restrictions, or sequencing gaps. Typical standby ranges from 25% to 75% of the daily equivalent, depending on contract language.
5) Delivery, mobilization, and demobilization
Transport may be billed as a flat charge or per kilometer. Per-kilometer pricing generally uses round-trip distance plus mobilization and demobilization fees for loading, dispatch coordination, and permits. Modeling delivery separately supports clear bid notes and defensible change orders.
6) Operator, overtime, and shift windows
Some rentals include an operator, while others require a separate labor line item. If the shift exceeds standard hours, overtime multipliers apply to the hourly equivalent. Enter realistic hours per day because compaction often follows paver output and can extend into evenings.
7) Fuel, insurance, and damage waiver
Fuel can be captured as a percent of the running subtotal or as a fixed amount for predictable projects. Insurance and damage waiver are frequently charged as percentages of base rental plus standby. Including these items protects margin and supports risk-aware budgeting and compliance.
8) Using the outputs in bids
The breakdown provides line-item totals, a grand total, and an estimated cost per day for quick benchmarking. Export the CSV for spreadsheets and attach the PDF to proposals. For negotiations, test discounts, tax rates, and delivery scenarios to match local rules and supplier incentives.
FAQs
1) What inputs are required for a reliable estimate?
Enter quantity, billing mode, base rate, and expected duration. Add minimum billing rules if applicable. Then include delivery, standby, operator, fuel, insurance, discount, and tax values to match your supplier quote and project conditions.
2) How is the daily equivalent rate calculated?
If you choose weekly or monthly billing, the calculator converts to a daily equivalent using 7 days per week and 28 days per month. That daily equivalent is used for standby cost and for the cost-per-day KPI.
3) When should I use standby days?
Use standby days for weather delays, restricted access, paver stoppages, or schedule gaps where the roller remains on site. Apply a standby percent that matches your contract so you do not understate true holding costs.
4) Does the delivery calculation include round trips?
Yes, per-kilometer delivery uses two times the one-way distance to represent a round trip, then adds mobilization and demobilization fees. Choose flat delivery if your supplier provides a single transport charge instead.
5) How are operator overtime costs handled?
Overtime hours are priced using an overtime multiplier applied to the operator hourly equivalent. If you use a daily operator rate, the calculator derives an hourly value from hours per day, then applies the multiplier to overtime hours.
6) What does the discount apply to?
The discount percent reduces the total after base rental, standby, delivery, operator, fuel, insurance, and waiver are added. This mirrors common rental quotations. Tax is calculated after discount to reflect typical invoicing practice.
7) Can I use the CSV and PDF for bids?
Yes. The CSV provides a clean line-item breakdown for spreadsheets, while the PDF creates a simple one-page summary for proposals. Recalculate whenever durations or transport distances change to keep supporting documents consistent.
Notes for estimating
- Confirm whether the supplier bills travel time as rental time.
- Check if tire ballast (water) setup is a separate charge.
- For long jobs, compare weekly and monthly pricing carefully.
- Use standby for weather, access constraints, and sequencing gaps.
Accurate rental planning keeps compaction budgets firmly controlled always.
