Learn how Storage Hunters: Open World mutation multipliers work in the calculator, including value groups, stacking decisions and shelf price comparisons.
Quick Answer
This site's calculator multiplies selected mutation multipliers together (M1 × M2 × M3), then applies markup, dynamic floor and condition math. Use the Mutation Guesser when the sell price is known and you want to compare the closest mutation candidates.
The calculator uses multiplicative mutation stacking, exactly matching the official wiki algorithm. That means selected mutation multipliers are multiplied together into one total multiplier before condition math is applied.
| Example mutations | Calculator multiplier | Meaning |
|---|---|---|
| Silver + Gold | 2 × 4 = 8x | Multiply both visible multipliers together. |
| Dirty + Gold | 0.8 × 4 = 3.2x | Dirty reduces the stack, but applies cleanly to Gold. |
| Diamond + Wet | 8 × 1.4 = 11.2x | High-value stacks grow exponentially when multiplied. |
The mutation table on the calculator and guesser pages is the fastest way to check the current multiplier list. Value effects with confirmed multipliers can be used directly in either tool, while Mint stays out because its customer-tip formula is not confirmed.
When you know the item, condition and shelf price but cannot identify the mutation, use the Mutation Guesser. It compares the price against known mutation candidates and shows the closest matches.
Compare shelf prices against likely mutation candidates.
Calculate final sell price from known mutations.
See what changed before trusting a new multiplier.
Yes. The calculator multiplies selected mutation multipliers together before applying markup, dynamic floor and condition math. This ensures maximum accuracy when pricing highly mutated items.
Mint sells at 1x plus a customer tip, but the tip formula has not been confirmed. It stays out of calculator inputs until that extra value can be calculated reliably.
