Alchemy values
Alchemy payouts for every item, and when casting beats selling on the Exchange.
Both alchemy values are pure functions of an item's value: low alchemy is max(1, ⌊0.4 × value⌋), high alchemy is max(1, ⌊0.6 × value⌋). These formulas were verified against all 4,562 tradeable rows carrying both fields — 4,562 of 4,562 match. The long-standing "residue" of cheap items breaking the pattern was always the 1 gp minimum floor.
Value in, coins out
- Abyssal whipvalue 120,001 → high alch 72.0K
- Rune platebodyvalue 65,000 → high alch 39.0K
- Nature runevalue 180 → high alch 108
Each row reads straight off the item's value and highalch fields — 0.6 × value floored, never rounded up.
Profit is not high-alch minus price alone: every cast consumes one nature rune (Nature rune, 140 gp). Cash per cast is highalch − buy price − nature-rune price, so an item only beats raw selling when that sum clears both the spread and the rune. The alch profit screen ranks that net figure by default, with the rune already subtracted; switch it to gross to see the spread before the rune. Buy in bulk through the flip finder.
