How this is calculated

Worked example, using the default values

Identify Input Parameters
4 parameters
TAC (tonnes) = 10000, Total quota shares = 1000, Your shares = 25, Fish price ($/kg) = 3.5 = 5 input(s) provided
Calculate Your quota
Your quota = round((yourShares / totalShares) * tacTonnes * 1000) / 1000
250 = 250
Calculate Share of TAC
Share of TAC = round((yourShares / totalShares) * 10000) / 100
2.5 = 2.5
Calculate Revenue potential
Revenue potential = round(yourQuotaKg * pricePerKg * 100) / 100
875000 = $875,000
