Fertiliser cost calculator: cost per kilogram of nutrient

Fertilisers are sold by the tonne, but a crop needs kilograms of nitrogen, phosphate and potash. Enter what each fertiliser costs you, or start from the latest world market prices, and see the cost per kilogram of nutrient, the cheaper way to supply your crop and the cost per hectare.

How to use this tool

  1. Choose your currency and enter your prices per tonne, or keep the world market prices.
  2. Optionally add a compound fertiliser you were offered with its N-P-K grade.
  3. Enter the nitrogen, phosphate and potash per hectare from your fertiliser plan, and the area.
  4. Compare the cost per kilogram of each nutrient and the two ways to supply your plan.

How it is calculated

Cost per kg of nutrient = price per tonne ÷ (1,000 × nutrient content). Urea has 46% N, DAP 18% N and 46% P2O5, TSP 46% P2O5 and potassium chloride 60% K2O. The P2O5 in DAP is costed after crediting its nitrogen at the cost of nitrogen from urea. The value of a compound fertiliser is its N, P2O5 and K2O priced at those straight-fertiliser costs.

Source of world prices: World Bank, Commodity Price Data (The Pink Sheet), monthly averages in US dollars per tonne, updated 3 November 2026, licence CC BY 4.0; converted with the ECB reference rate of 12 November 2026. Grades are the standard nutrient contents; check the label of the product you buy.

Questions and answers

What do the N-P-K numbers mean?

The percentage of nitrogen (N), phosphate (P2O5) and potash (K2O) by weight. DAP 18-46-0 contains 180 kg of N and 460 kg of P2O5 per tonne.

How do I convert P2O5 to P and K2O to K?

Multiply P2O5 by 0.4364 to get phosphorus (P) and K2O by 0.8301 to get potassium (K). Fertiliser plans and labels usually use the oxide forms.

Why are world market prices lower than my dealer’s price?

World prices are for bulk cargoes at export ports or on arrival. A farm pays transport, storage, distribution, bagging and the dealer’s margin on top, so enter your own prices for a farm-level cost.
