OSRS High Alch Profit Guide — which items actually profit
High Alchemy turns an item into coins on the spot. Done right it's steady gold while you do something else; done wrong you lose money on every cast. Here's the honest math.
The formula
Profit per alch = High Alchemy value − what you paid for the item − the nature rune cost. Crucially, there's no Grand Exchange tax — you're alching the item for coins, not selling it on the GE. So unlike flipping, the alch math is just those three numbers.
What you need
- Level 55 Magic for the High Level Alchemy spell.
- Nature runes (one per cast) — their price is part of your cost, so it matters.
- It's an active method: you can cast roughly 1,200 times an hour, so think in profit-per-hour, not just profit-per-item.
Finding profitable items
You want items whose High Alch value comfortably beats their buy price plus the nature rune. These shift constantly with prices, and many items alch at a loss — which is why a live board beats a static list.
Watch the nature rune price and buy limits, and remember the 1,200/hr ceiling when comparing alching to flipping or other methods (is flipping worth it). Not affiliated with Jagex; not financial advice.
