OSRS Giants’ Foundry Calculator Formula
The calculations are based on estimating your XP per sword, then multiplying by your production rate. Gold profit is derived from the point exchange rate and deducted metal cost.
1. XP per Sword: XP_SWORD = 1000 + (Smithing Level – 1) * 40
2. Total XP/Hr: TXP = Swords Per Hour * XP_SWORD
3. Total Points/Hr: TP = Swords Per Hour * Avg Points Per Sword
4. Net Profit/Hr: NP = (Total Points/Hr * 120 GP) – (Swords Per Hour * Metal Cost)

Variables Used in the Calculator
- Smithing Level: Your current Smithing level, which directly affects the base XP gained per successful forge.
- Swords Forged Per Hour: Your personal efficiency metric, measured by how many finished swords you complete in 60 minutes.
- Average Points Per Sword: The total amount of points (foundry and reputation) earned per sword, used to calculate potential gold profit.
- Metal Cost Per Sword (in GP): The total Grand Exchange cost of the bars required to make one sword. This is deducted from the gross gold income to find your net profit.

What is the Giants’ Foundry?
The Giants’ Foundry is a Smithing minigame located in the Dwarven Mine, offering significantly higher Smithing experience rates than traditional methods like Platebodies, particularly for mid-level players. It involves combining two types of metal bars to forge a sword according to the Giant’s specifications, cycling through phases like heating, pounding, grinding, and polishing.
The minigame is popular because it converts low-cost bars (like Iron and Steel) into very high experience, making it a viable alternative to the much slower and more click-intensive traditional smelting methods. Successful forging awards Smithing XP, and the Giant rewards the player with Foundry Points, which can be exchanged for useful rewards like the Smithing outfit, moulds, and a considerable amount of coin.
How to Calculate Giants’ Foundry Profit/XP (Example)
- Determine Input Variables: Assume a player has 85 Smithing, completes 12 Swords per hour, earns 185 points per sword, and the raw metal cost is 25,000 GP per sword.
- Calculate XP per Sword: Use the formula: $1000 + (85 – 1) \times 40 = 1000 + 3360 = 4360 \text{ XP/Sword}$.
- Calculate Total Hourly XP: Multiply the rate by the XP per sword: $12 \text{ Swords/Hr} \times 4360 \text{ XP/Sword} = 52,320 \text{ XP/Hr}$.
- Calculate Total Hourly Points: Multiply the rate by the points per sword: $12 \times 185 = 2,220 \text{ Points/Hr}$.
- Calculate Net Profit: Total Gross Gold is $2,220 \text{ Points} \times 120 \text{ GP/Point} = 266,400 \text{ GP}$. Total Metal Cost is $12 \text{ Swords} \times 25,000 \text{ GP/Sword} = 300,000 \text{ GP}$. The Net Profit is $266,400 – 300,000 = -33,600 \text{ GP/Hr}$ (a loss).
Frequently Asked Questions (FAQ)
What is the best metal combination for profit? The most profitable combinations often involve using low-cost bars like Steel or Iron with higher-value bars like Mithril or Adamant, and selling the rewards for the highest current Grand Exchange value. However, the profit margin is heavily dependent on real-time bar prices.
What is the maximum XP/hour at the Giants’ Foundry? Optimal setups and high Smithing levels (99) can achieve rates exceeding 180,000 XP per hour, but this requires extreme focus and perfect execution, often using premium metals.
Is the Giants’ Foundry better than Blast Furnace? For raw Smithing XP, the Giants’ Foundry generally surpasses the Blast Furnace, especially if you are using your own metal supply. The Blast Furnace is typically used for rapid bar creation, not direct XP gain.
What are Foundry Points used for? Foundry Points are mainly used to purchase the Smithing skill outfit, various sword moulds that increase XP/point efficiency, and the Smithing skill cape (at level 99). The remainder can be exchanged for the Giant’s Gold, which is where the GP profit comes from.
