How do you calculate cost per ton in a grain mill?

Multiply tons by your variable cost per ton (and any cost-share factor), add the fixed run cost, then divide by tons. For 150 tons at $72/ton plus $1,800 fixed, total is $12,600, or $84 per ton.

Why is my cost per ton higher than my variable cost per ton?

Because fixed run cost is spread across the tonnage. At $72/ton variable, the $1,800 fixed cost adds $12/ton over 150 tons, giving $84/ton total.

What is the included cost share field for?

It lets you apply only a portion of the variable rate — useful when costing a partial cost element. At 100% the full $72/ton applies; at 50% only half flows into the variable total.

How does run size affect cost per ton?

Fixed cost is constant, so longer runs dilute it. The same $1,800 fixed over 300 tons would add only $6/ton instead of $12/ton, dropping total cost per ton accordingly.

What is a good cost per ton for feed milling?

It varies widely by formula, energy price, and plant scale, so benchmark against your own history and quoted price rather than a universal figure. The value of this tool is comparing runs on equal footing.

Cost per ton vs cost per bag — which should I quote on?

Quote on whichever your customer buys by. Cost per ton suits bulk and tolling; convert to cost per bag by dividing total cost by bag count when selling packaged product.

Grain Milling, Dry Bulk Food & Feed Handling calculator

Cost Per Ton Calculator

Cost per ton is the all-in cost to mill, blend, or handle one ton of grain or dry-bulk product across a run, including both the variable cost that scales with tonnage and the fixed cost of setting up and running the line. Mill managers, cost accountants, and sales teams quoting tolling work rely on it to price feed batches, flour lots, and dry-bulk runs without giving away margin. Because it separates the per-ton variable cost from the fixed run cost, it shows exactly how much cheaper a longer run gets as fixed cost spreads over more tons. It is the number that decides whether a quote wins business profitably.

What this calculator does

Estimate dry bulk production cost exposure and cost per ton using processed tons, variable cost per ton, included cost share, and fixed run cost.
Use it when quoting flour, feed, meal, pellets, or dry ingredients and you need to combine material, milling, handling, packaging, labor, energy, and setup costs on a ton basis.
It computes total run cost by adding variable cost (tons times per-ton rate times the applied cost share) to a fixed run cost, and reports the resulting cost per ton.

Formula used

Variable dry bulk cost = processed or quoted tons × variable cost per ton × included cost share
Total dry bulk run cost = variable dry bulk cost + fixed run cost

Inputs explained

Tons processed or quoted:
Variable milling cost per ton:
Variable cost share applied:
Fixed run cost (setup & overhead):

How to use the result

Use it when quoting a milling or tolling job, setting an internal transfer price, or checking whether a run's actual cost matched estimate.
It assumes a flat variable cost per ton across the whole run; real mills see cost climb at low rates or during energy peaks, so treat very small runs cautiously.

Current U.S. benchmarks

The producer price index for steel mill products stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. Quotes priced off last quarter's material cost miss this move.
Industrial natural gas averages $4.9 per Mcf (EIA, Apr 2026), down 7.7% from a year earlier, with industrial electricity at 8.66 cents per kWh. Process heating and refrigeration budgets track both.
The U.S. has 17,154 machine shops establishments employing about 223,303 workers (Census County Business Patterns, 2023).
