Average fuel consumption (per hour)

That could be the 'real world' data for your plane (if you know that) or
the following formula:

FC = (S.F.C. x HP or lbs. thrust) - 30%

Average fuel cost (per hour)

Not included in the DOC calculation, but required to file flights in the

$/h = FC * 0.34


Fuel price is being averaged by Mr. Hak at 0.34 $ per lb.
