Choose two parents to see the child.
Passive skill odds
The child first inherits some of the parents' passives, then rolls extra random ones, up to four in total. Count the different passives across both parents and how many of them you want on the child.
Pick a Pal to see every pair that makes it.
Add the Pals you have and pick a goal. The shortest chain of pairs appears here.

How breeding works in Palworld
Every Pal carries a hidden breeding power. When two different Pals breed, the game adds the two powers, halves the total and rounds down, then picks the Pal whose power is closest to that number. If two Pals are equally close, the one the game lists first wins. Two of the same Pal always make that Pal.
That rule has a ceiling. A child can never be rarer than the rarer parent, so a common Pal bred with Anubis makes something in between, never a second Anubis. Breed the child back with the rare parent and each generation lands closer to it.
Special pairs
Before doing any maths the game checks a short list of fixed pairs. Relaxaurus and Sparkit always make Relaxaurus Lux. Vanwyrm and Foxcicle always make Vanwyrm Cryst. Those subspecies only come from their pair, and there are 82 pairs on the list in the 1.0 game data. The Special combos tab shows all of them.
Self-only Pals
Twenty four Pals never come out of a mixed pair, whatever the powers say: Jetragon, Frostallion, Paladius, Necromus, Orserk, Shadowbeak, Faleris, Grizzbolt, Lyleen and the other Pals listed under the Special combos tab. To breed one you need a male and a female of that Pal.
Gender
You always need one male and one female. For all but two pairs the child is the same whichever parent is which. A female Katress with a male Wixen makes Katress Ignis, and a male Katress with a female Wixen makes Wixen Noct. Each Pal also has its own odds of hatching male or female, shown under every result.
Passive skills
The child first rolls how many passives it inherits from the parents (one to four, with one the most likely), then rolls how many random passives it adds on top (none the most likely), and keeps at most four. The odds card under a result turns those two rolls into one number for your parents.
Where the numbers come from
The pair table, powers, special pairs and gender odds are read out of the game files by PalCalc (MIT licence), the open source breeding solver. This page ships PalCalc v28, built from Palworld 1.0.
The calculator applies the game's own rule rather than a copy of the table. Before this page went live every one of the 41,616 pairs the game knows was run through it and compared with the datamined answer. All 41,616 matched.

Breeding on your own server
Egg hatching time is a server setting. On a dedicated server you can hatch a huge egg in minutes instead of days, and the panel's Palworld settings form changes it without touching a file.
Questions about Palworld breeding calculator
Every Pal has a hidden breeding power. When two different Pals breed, the game averages the two powers and the child is the Pal whose power sits closest to that average. Two of the same Pal always make that Pal. A short list of special pairs ignore the average and make a specific subspecies instead.
