→Calculations in the cash flow model

::<math>-~\text{Wellhead taxes}~-~\text{Operating costs}~-~\text{Federal income taxes} \ </math>
After the revenue and expenditure schedule has been determined, we can now calculate cash income taxes for our project. Finally, once the cash income taxes have been calculated for each year, the [[The time value of money|cash flow time diagram]] can be prepared and we are ready to calculate the net present value for our venture.
