Profitability calculator

Estimate profit per cycle, profit per hour, margin and ROI for every building. Prices are pulled from the live market — and you can override any of them.

Pick a recipe, adjust the building level and quality bonuses, and see at a glance whether to produce or buy on the market. Use "Share result" to generate a permanent link with your configuration.

How the math works

The calculator uses a simple, transparent formula so you can sanity-check the numbers by hand:

  • Revenue per cycle = output amount × sale price × (1 + output quality bonus).
  • Input cost per cycle = sum of (amount × input price × (1 − input quality bonus)).
  • Wages per cycle = recipe's base wage × wage multiplier.
  • Profit per cycle = revenue − input cost − wages.
  • Profit per hour = profit per cycle × (3600 ÷ cycle time in seconds).
  • ROI in hours = building cost ÷ profit per hour (only when positive).

Quality bonuses are modelled as a flat percentage on price: 0.20 = +20%. It's a useful approximation for comparing recipes; the full in-game model has quality shelves and non-linear curves that we'll layer on next.
