Production and payback calculator

Compare two lines using measured throughput, stock, sale price and costs.

Enter your own observed values. Rates use units per minute; all money values use the same in-game currency. No game prices or machine speeds are prefilled.

Compare the same material in the same unit. If processing changes units, convert every rate and stock to equivalent final-product units first. This estimate assumes steady flow, enough power, no losses, and operating costs stopping when the stock runs out.

How it is calculated

Capacity = lowest stage rate. Time = stock ÷ capacity. Net income/min = capacity × price − running cost. Stock profit = stock × price − time × running cost − investment. Payback = investment ÷ net income/min, only while enough stock remains.
