The Rat Market (Guide)/Calculators
Since the rework of the Rat Market, the amount of 
Rat-Shillings received per item sold is somewhat more difficult to calculate. In general, items receive a 32% markup until you hit 65,000 Rat Market Saturation (or 
625 in base value sold), then a 12% markup until you hit 180,000 Rat Market Saturation, (or 1,800 in base value sold). After 180,000, you simply receive the echo value of the item in Rat-Shillings. Neither the order of sale, the number of items you sell at once, nor the exact mix of items used has any effect on the total shillings gained; it is simply a product of the total echo value of all items sold. These calculators will take all that into account for you. Note that Fourth-City Echoes are excluded from all these calculations, as those are always sold for 125 shillings and neither benefit from nor add to saturation.
Number of Turn-Ins Required[edit]
