This calculator determines expected yield, cost, and profit of planting and picking herbs on a per run basis. Per patch calculations are listed below the main table.

  • All prices are based on Grand Exchange prices, including seeds, herbs, and compost.
  • The price of goutweed, whilst not having a specific Grand Exchange value, has an inherent value based on the exchange value of the herbs it provides when exchanging goutweed with Sanfew. The expected value is obtained based on the probabilities listed.
  • Expected chance of disease leading to death based on , where is the probability of disease per stage and is the number of growth cycles the crop requires to fully grow.
    • Expected chance of disease leading death whilst using Resurrect Crops is based on where is the probability of disease per stage, is number of stages a crop has to grow, and is the chance for Resurrect Crop to succeed.
  • Expected yield based on negative binomial distribution of
  • Rounding down is used on all base chances as is expected with RuneScript.[1]
  • Composting experience is not included in the total run experience.
