Trade Ship Income Calculator

Calculate OpenFront trade ship gold by port distance. See on the curve why anything under 300 tiles is effectively worthless.

The curve is a sigmoid that bends sharply near distance 300. Try short distances to see why clustering ports is wasted gold.

Formula used

gold = 75000 / (1 + e^(-0.03 * (distance - 300))) + 50 * distance

The curve is a sigmoid that bends sharply near distance 300. Income at distance 100 is roughly a tenth of what you get at 300. Spread your ports as far apart as the map allows and aim them at distant foreign ports.
