Why a Single Fixed Result Is Misleading
Giants' Foundry rewards depend on the sword being made, its mould fit, quality, mistakes, and player execution. Use the OSRS Giants' Foundry Calculator with measured average values for your setup.
Mould Score
Published calculator documentation based on Wiki formulae gives average mould-score references of approximately 37.667 without mould unlocks and 58.25 with moulds unlocked. These are planning references, not a promise for every commission.
XP per Sword
The most reliable planning input is the average XP from a meaningful sample of completed swords using the same alloy and mould strategy.
Reputation
Enter average reputation per sword. Multiply it by swords required to estimate reward-shop progress.
Materials and Value
Track bars or usable equipment consumed per sword and assign a current opportunity value. Subtract expected reward value to estimate net cost.
Speed
The Smiths' outfit can improve effective speed. Use a sustainable swords-per-hour figure measured over longer sessions.

Frequently Asked Questions
- Is mould score the only factor?
- No. Alloy, quality, mistakes, section count, and execution also affect the final result.
- Should I use bars or equipment value?
- Use the actual opportunity value of the materials you plan to consume.
- How should I estimate speed?
- Measure completed swords across a normal session rather than a short perfect test.
