OSRS High Alch Profit and Break-Even

Use the calculator first

Open the OSRS High Alch Calculator and replace the example defaults with values for the exact OSRS activity you are modeling.

Formula and assumptions

Input cost per alch equals item cost plus Nature rune cost. Profit per alch equals High Alchemy value minus input cost per alch. Total input cost and coins received multiply their per-cast values by quantity. Total profit equals coins received minus total input cost. Time divides quantity by alchs per hour, and GP per hour divides total profit by estimated hours.

Worked example

If an item costs 1,000 GP, a Nature rune costs 100 GP, and the item alchs for 1,200 GP, estimated profit is 100 GP per cast before other opportunity costs.

Visual explanation

The calculator includes a live result diagram and a calculation-flow diagram. They use the same inputs and outputs as the calculator rather than a separate hidden model.

Important limitations

The calculator does not fetch live Grand Exchange prices, enforce buy limits, include item acquisition time, model rune-saving effects, account for opportunity cost, or guarantee that enough items can be bought at the entered price. High Alchemy values and market prices should be verified before trading.
