  • High Alch Value: The fixed gold output when using High Level Alchemy on the item.

What is High Alch Calculator?

A high alch calculator is an essential tool for players looking to train the Magic skill profitably. High Level Alchemy is a spell that converts items into gold based on a fixed percentage of their “store price.”

Because Nature Runes and items fluctuate in price on the Grand Exchange, using a calculator ensures you aren’t losing money while gaining experience. It accounts for the total investment (item + rune) versus the guaranteed return.

How to Calculate High Alch Profit (Example)

  1. Find the High Alch Value of your item (e.g., Rune Platebody is 39,000 GP).
  2. Check the Buy Price on the GE (e.g., 38,200 GP).
  3. Add the cost of one Nature Rune (e.g., 90 GP). Total cost = 38,290 GP.
  4. Subtract total cost from alch value: $39,000 – 38,290 = 710$ GP profit per cast.
