Agriculture Benefit Cost Ratio:

\[ BCR = \frac{NI}{TC \cdot OP} \]

Where:

• \(BCR\) is the benefit cost ratio (decimal).
• \(NI\) is the net income in currency per year (P/year).
• \(TC\) is the total cost in currency per day (P/day).
• \(OP\) is the operating period in days per year (days/year).
