How the calculator works

The calculator above splits the cost of one ton of hot mix into seven parts:

bitumen      = binder content × bitumen price
aggregate    = (1 − binder content) × aggregate price
fuel         = fuel per ton × fuel price
electricity  = kWh per ton × electricity price
wear parts   = your maintenance cost per ton
crew         = crew cost per shift ÷ tons per shift
fixed        = fixed costs per year ÷ tons per year

Enter your own delivered prices in one currency. The defaults are placeholders so the calculator shows numbers — they are not market prices.

Where to find your inputs

Input Where it comes from
Binder content Your approved mix design (often 4–6% for dense-graded mixes)
Bitumen and aggregate prices Delivered to your plant, per ton
Fuel per ton Plant data sheet; Roadmixa batch plants list about 5.5–7 kg fuel oil per ton under typical conditions
Electricity per ton Installed kW × load factor ÷ tons per hour, or your meter readings
Wear parts Maintenance records; start with the supplier’s estimate
Crew per shift Wages for everyone running the plant (not paving)
Fixed costs Plant cost per year (depreciation or financing), site, permanent staff, insurance, permits

What moves cost per ton most

Lever Why it matters
Binder content Bitumen is the most expensive input; stay on the mix design, not above it
Aggregate moisture Every extra percent of water costs fuel — see stockpile management
Utilization Fixed costs spread over more tons — sell or pave more, run steadier shifts
Burner tuning Correct air-fuel ratio saves fuel — see burner tuning
RAP Replaces new aggregate and part of the new binder where allowed — see the recycling payback method

Using the result

  • Pricing your mix: add delivery, overheads and margin to the plant cost per ton
  • Buy or own: compare with the delivered price of bought mix — see the break-even check
  • Business plans: use the result in your cash-flow model — see the business plan guide
