OSRS Giants Foundry Calculator

This calculator works out what a sword from the Giants' Foundry is worth before you pour it. Choose the two bar types and how many of each go into the 28-bar crucible, add the mould score your commission is offering and any mistakes, and it returns the metal score, the finished sword quality, the Smithing experience paid on handover and the reputation earned. A second mode turns a Smithing goal into a count of swords and a shopping list of bars. It uses the published quality and experience formulas only, so nothing here depends on reward shop prices that an update can change.

Calculator Type
The crucible holds 28 bars, so the two counts have to add up to 28.
Leave at zero for a crucible of one metal.
The bonus for matching the two styles the commission asks for. It changes with every commission and the best any commission can reach is 69, so read it off the one you have rather than assuming.
Wrong tool or wrong heat. Each one costs 5 quality.
