Positive

● Main Annual Revenues ($/yr)
The annual revenues associated with the stream that is specified as the “Main Product/Revenue” stream. Note that this variable is only displayed if there are more than one revenue streams; for more details, see Revenues.

● Annual Production Rate (or Annual Processing Rate or Cost Basis Annual Rate) (kg MP/yr)
The selected annual mass flow rate basis (total flow or component flow) of the stream that is specified as the “Unit Reference” stream through the “Rate Reference Flows” dialog. If the “Main Product/Revenue” stream is selected, the corresponding annual rate is denoted as “processing” or “production’, respectively. If a different stream is selected, this corresponding annual rate is denoted as “cost basis’. Note that if a “Unit Reference” stream does not exist, this variable will not be displayed; for more details, see Operating Cost.

0.0

Positive

● Unit Production Cost (or Processing) Cost ($/kg MP)
A reference unit cost that is calculated by dividing the AOC by the annual mass flow rate basis (total flow or component flow) of the stream that is specified as the “Unit Reference” stream through the “Rate Reference Flows” dialog. Depending on whether this is a process input or output stream, the corresponding cost is denoted as “processing” or “production’, respectively. Note that if a “Unit Reference” stream does not exist, this variable will not be displayed; for more details, see Operating Cost.

0.0

Positive

● Net Unit Production (or Processing) Cost ($/kg MP)
A reference unit cost that is calculated by dividing the net AOC by the annual mass flow rate basis (total flow or component flow) of the stream that is specified as the “Unit Reference” stream through the “Rate Reference Flows” dialog. Depending on whether this is a process input or output stream, the corresponding cost is denoted as “processing” or “production’, respectively. Note that if a “Unit Reference” stream does not exist, this variable will not be displayed; for more details, see Operating Cost.

0.0

Positive

● Unit Production (or Processing) Revenue ($/kg MP)
A reference unit revenue that is calculated by dividing the annual revenues by the annual mass flow rate basis (total flow or component flow) of the stream that is specified as the “Unit Reference” stream through the “Rate Reference Flows” dialog. Depending on whether this is a process input or output stream, the corresponding cost is denoted as “processing” or “production’, respectively. Note that if a “Unit Reference” stream does not exist, this variable will not be displayed; for more details, see Revenues.

0.0

Positive

● Gross Margin (%)
This is a measure of profit that directly tells you what percentage of the annual revenues is gross profit; for more details, see Profitability Analysis.

0.0

Positive

● ROI (%)
The return on investment (ROI) is a profitability measure used to evaluate the viability of an investment or to compare the profitability of a number of different investments; for more details, see Profitability Analysis.

0.0

Positive

● Payback Time (years)
This is a measure of the time needed for the total capital investment to be exactly balanced by the cumulative net profits; for more details, see Profitability Analysis.

0.0

Positive

● IRR (after tax) (%)
The internal rate of return (IRR) after taxes is the interest rate for which the net present value (NPV) of a project is zero; for more details, see Cash Flow Analysis.

0.0

Positive

● NPV at 7% ($)
The net present value (NPV) is a profitability measure used to evaluate the viability of an investment or to compare the profitability of a number of different investments; it represents the total value of future net cash flows during the lifetime of a project, discounted to reflect the time value of money at the beginning of the project; here, it is calculated for the low value specified for the interest rate. The default value of the program for this rate is 7%; for more details, see Cash Flow Analysis.
