What is an OSRS Calculator for Magic?
An OSRS Calculator for High Alchemy is an essential tool for players looking to train their Magic skill while making a profit or breaking even. In Old School RuneScape, economy management is as crucial as experience gaining. High Alchemy converts items into gold, but because the cost of items and Nature Runes fluctuates daily on the Grand Exchange, manually calculating margins is difficult.
By using this tool, players can input real-time prices to identify “Alchables”—items that generate more gold when alchemized than they cost to acquire. This process helps players fund their membership bonds and equipment upgrades efficiently.
How to Calculate Profit (Example)
Suppose you want to train Magic by alching a Yew Longbow. Here is how the calculation works step-by-step:
- Determine High Alch Value: A Yew Longbow alchs for 768 gp.
- Check Item Cost: You buy the bow on the GE for 550 gp.
- Check Rune Cost: A Nature Rune costs 90 gp.
- Apply Formula: 768 – (550 + 90) = 768 – 640.
- Result: Your profit is 128 gp per cast.
Frequently Asked Questions (FAQ)
Do I need 55 Magic to use this OSRS calculator?
Yes and no. The calculator itself works for anyone, but in-game, you must have level 55 Magic to cast High Level Alchemy. If you are lower level, use the Low Alchemy values instead.
Does this calculator account for the Staff of Fire?
This calculator assumes you are using a Staff of Fire (providing infinite Fire Runes). If you are buying Fire Runes, you must add their cost to the “Nature Rune Cost” field manually.
What is the buy limit in OSRS?
Every item has a Grand Exchange buy limit (usually every 4 hours). This calculator determines profit per item, but your total hourly profit depends on volume limits.
Is High Alchemy the best way to make money?
It is a low-intensity method. While bossing often yields higher gp/hr, using an OSRS calculator to find good alch items provides consistent, risk-free gold while gaining XP.
