Palworld Mutation Calculator
This Palworld 1.0 mutation calculator compares mutated egg odds, Cake choices, passive inheritance estimates, and the baseline species result before you commit a breeding project.
Mutation tool
Plan mutated eggs after the normal child check
The species result appears here once the breeding data is ready.
Palworld mutation chance for at least one mutated egg across 25 egg rolls with the selected Cake. Each egg uses 3.00% mutation chance.
10.0% per egg for the selected inherited-passive set. Combined mutation plus passive-set chance over these batches is 7.24%. Treat this combined number as planning math, not an official guarantee; random extra passives are not modeled.
How to use the Palworld mutation calculator
- Choose the two parents you will actually breed.
- Check the baseline species result before choosing a Cake.
- Pick the Cake you plan to use for each breeding batch.
- Enter the number of batches you are willing to run.
- Use the passive controls only when you are also targeting inherited parent passives.
The Palworld mutation calculator is best used after the species route is already correct. Mutation can improve an egg outcome, but it does not replace parent-pair lookup.
Cake effects used by this tool
| Cake | Alias | Eggs | Mutation rate | Use when |
|---|---|---|---|---|
| Standard Cake | - | 1 egg | 1.00% per egg | Baseline breeding after the species result is confirmed. |
| Mushroom Cake | - | 1 egg | 1.00% per egg | Stat-potential projects, not extra mutation rolls. |
| Vegetable | - | 2 eggs | 1.00% per egg | Two independent egg rolls from one breeding cycle. |
| Deluxe | Extravagant in some database tools | 1 egg | 3.00% per egg | Mutation hunting with the strongest per-egg rate used by this tool. |
| Special Cake | - | 1 egg | 1.00% per egg | Parent-passive inheritance when the parent pool is already clean. |
What the tool does not predict
This page does not predict a mutated egg's species. The baseline species result comes from this site's breeding dataset, but the mutation species-selection routine is not treated as public, verified data here.

Source notes
The Palworld mutation calculator uses source layers carefully. Official 1.0 release notes confirm Mutation as a low-chance breeding mechanic and list the new Cake effects. Official notes and database tools do not always use the same item name, so the table keeps the player-facing alias beside the release-note wording. The numeric odds used here come from current community game-file tooling and database references, so keep them patch-sensitive if Palworld changes breeding again. Combined mutation plus passive-set odds multiply two planning estimates and should not be read as an official guarantee.
Palworld mutation calculator FAQ
What does this Palworld mutation calculator do?
This Palworld 1.0 mutation calculator estimates mutated egg odds from Cake choice, breeding batches, egg count, and parent-passive inheritance settings. It also checks the baseline species from two selected parents with the site's current breeding data.
What is the mutation chance in Palworld 1.0?
The calculator uses 1.00% per egg for Standard, Mushroom, Vegetable, and Special Cake, and 3.00% per egg for the Deluxe / Extravagant mutation cake. The 1.00% and 3.00% values are community data-tool references, not official guarantee text.
Why do some tools say Deluxe or Extravagant?
The official 1.0 changelog uses Deluxe Vegetable Cake. Some Palworld databases and search results use Extravagant Vegetable Cake for the same mutation-focused item, so this page keeps both names in the notes.
Which Cake should I use for Palworld mutation hunting?
Use the Deluxe / Extravagant mutation item when mutation chance is the goal. This tool uses 3.00% mutation chance per egg for that choice, compared with 1.00% for Standard, Mushroom, the two-egg option, and Special.
Why does the two-egg option change batch odds?
That choice produces two eggs in one breeding batch. Each egg still uses the normal per-egg mutation chance, but two rolls make the batch chance higher than one roll.
Are passive odds exact?
They are estimates for inherited parent-passive sets using the 40% / 30% / 20% / 10% roll for one through four slots, with Special Cake forcing four parent-passive slots. The combined mutation plus passive-set number is planning math, not an official guarantee; random extra passives are not modeled.
Can mutated eggs hatch a different species?
Yes, current community data references treat mutated eggs as a separate result branch, so the mutated egg is not guaranteed to match the baseline species. This Palworld mutation calculator shows the species check and the mutation odds, not the final mutated species.
