The OSRS Wiki lists average loot value for most bosses, or you can use your own drop log's average from the loot tracker plugin.
Wiki figures often assume ideal kill rates and don't always account for your specific supply costs — enter your own numbers for a more personalized estimate.

Not every OSRS boss that looks profitable on paper actually is, once you factor in realistic kill rates and the cost of the supplies burned getting there. Gross loot value alone can be misleading.
This calculator nets out your supply costs against your loot value and kill rate to give you an honest GP-per-hour figure, so you can decide which boss is genuinely worth your time — or your gold, if you'd rather have our team farm it for you.
