How does Material Efficiency change cost?

Material Efficiency reduces every input quantity by its percentage, so ME 10 uses 10% less of each material. The result is rounded up and can never fall below the number of runs, which means ME saves the most on bulk, high-quantity materials.

EVE charges a manufacturing job installation fee based on the estimated value of the item being built and the system's cost index. This tool models it as a percentage of a job cost base you enter, which you can read from the industry window before you start the job.

How do I cost a multi-stage build?

Add each intermediate component as its own line and enter its already-built cost as the per-unit price. That folds the cost of sub-components into the final total, so you see the true cost of a full production chain rather than just the final assembly step.

Why is the adjusted quantity rounded up?

EVE rounds each ME-reduced material requirement up to a whole number per job, and the minimum is one unit per run. The calculator applies the same ceiling, so the quantities match what the industry window will actually ask you for.

How do I know if a build is profitable?

Enter the sell price of one finished unit and the tool multiplies it by your runs, subtracts total cost, and shows profit. Remember to factor in sales tax and broker fees on the sell order, which this figure does not yet include.

Cost an EVE Online build before you commit

Manufacturing in EVE only pays if the materials plus fees come in under the sell price, and Material Efficiency quietly changes every quantity. This calculator does the full sum for you — ME-adjusted material amounts, the job fee, cost per unit, and profit at your chosen sell price — so you can decide whether a blueprint is worth running. Everything stays in your browser.

How it works

For each material, the quantity needed for a job is the base quantity times runs, reduced by Material Efficiency, rounded up, and never below the number of runs:

adjusted = max(runs, ceil(baseQty * runs * (1 - ME/100)))

Each material’s cost is that quantity times its price; summed across all lines gives the material subtotal. The manufacturing job fee is a share of the job cost base:

jobFee = jobCostBase * (feePercent / 100)
total  = materialSubtotal + jobFee

Example and tips

Building from a blueprint at ME 10 with 3,500 Tritanium, 900 Pyerite and 150 Mexallon per run cuts each quantity by 10% before rounding, then adds the install fee. Divide the total by runs for a true cost-per-unit and compare it against the market. Two practical tips: ME pays off most on bulk minerals, not tiny inputs that round back up to the run count; and to cost a reaction or T2 chain, enter each intermediate as its own line priced at what it costs you to build. Don’t forget sales tax and broker fees when judging the final profit.
