Features & Capabilities

Think of the cheapest defender's price as the "baseline cost" or "fixed cost" for acquiring any defender. The difference between this baseline and a player's actual price is the "marginal cost" – the extra amount you'd spend to acqu ire a premium player over the most affordable option.

For example:

Ben Chilwell's actual FPL price: 5.5m. Baseline cost (cheapest defender): 4.0m. Marginal cost for Chilwell: 1.5m (5.5m - 4.0m). If the baseline drops to 3.9m (due to a price decrease for the cheapest defender), the marginal cost for Chilwell be comes 1.6m (5.5m - 3.9m).

This method highlights the additional amount you're investing in Chilwell over the base option. It offers a more tra nsparent view of players' relative values, especially when weighing premium players against budget choices.
