How do you calculate payload in an aircraft?

Max payload that can be carried on an aircraft can be derived as following;

Max Payload = MTOW - (OEW + Fuel Capacity).

In case of B727-200, MTWO = 95,208 kg, OEW = 45,360 kg and max fuel capacity = 37,020 L (29,616 kg). Hence Max Payload on B727-200 is;

Max Payload = MTOW - (OEW + Fuel Capacity);

or Max Payload = 95,208 - (45,360 + 29,616)

or Max Payload = 95,208 - 74,976 kgs

hence Max Payload = 20,052 kgs

Hope this helps.
