The co-operative said that, when combined with the previously announced estimated dividend range of 25-35 cents per share, its cash payout would be $4.95 to $5.05 for the season.
AgriHQ analyst Susan Kilsby said it was too early to say whether the positive price trend would continue into 2015.
"Fonterra factored in a steady increase in dairy commodity prices into its $4.70/kg milk price, therefore prices need to keep moving higher if this price is to be achieved," she said in a market commentary.
Much of Fonterra's thinking centres on wholemilk prices recovering at some point to their long-run average of around US$3500 a tonne.
Falling oil prices, geopolitical uncertainty in Russia and Ukraine, and subdued demand from China have all contributed to sharply weaker prices this year.
