Palworld 1.0 Breeding Calculator

It reads the game's own breeding table to answer two questions: what two parent Pals produce, and which parent pairs can produce a Pal you name. The child, its breeding rank, base stats, guaranteed passives, partner skill and drops all arrive with the result.

Open Parents → Child mode, pick Parent A and Parent B, and the child appears in place with no reload. Each box matches a Pal by name, Paldeck number or a known alias.

Open Target → Parents mode and name the Pal you want. The calculator returns every pair in the 1.0 table that hatches it, and the list keeps its search, its sort and the Pals-you-own filter however long it runs.

Yes. The running dataset is Palworld v1.0 (build v28), last verified 2026-09-16, and both are printed with the data table on this page so a patch can be checked against them instead of trusted.

Both work, in either direction. Type a name, a Paldeck number, or the alias a Pal is better known by, and the list narrows as you type.

No. Either Pal can be entered first, and the average lands in the same place whichever way round the pair is written. One pair is the exception: it hatches two different children depending on which parent is the female, and the calculator shows both outcomes instead of choosing one for you. The Palworld 1.0 Breeding Combination guide lists it with the rest of the fixed combinations.

Yes. The 138 fixed combinations are checked before any rank is averaged, and a result that comes from one is labelled a special combination so the two routes are never confused. They cover 90 different children. The Palworld 1.0 breeding formula guide sets out the rule order.

Two of the same species always breed true, which makes a pair of one species the cheapest way to reroll passive skills. It is also the only pairing that works for 26 Pals — the legendaries, the raid bosses and a few subspecies — because no two different parents can reach them.

Because it sits outside the pool the child is drawn from, so no two different parents can land on it. 26 of the 299 Pals are in that position, and the single row listed is the Pal with itself. That row is the whole route rather than a list cut short.

Every result carries the child's breeding rank, base stats, work suitability, guaranteed passive skills, partner skill, drops and egg, and links to that Pal's own page, where the same attributes sit beside its complete parent list.

Nothing is truncated. Felbat has the longest list in the 1.0 table at 1,280 pairs, and all 1,280 are on the page. The list is sorted, filtered and loaded a screenful at a time in the browser rather than summarised.

Yes. Every pair list carries a search box, a sort, and the Pals-you-own filter, so a list running to four figures can be narrowed to the handful of pairs you can breed today without leaving the page.

My Palbox is the list of Pals you own, kept in your own browser and used to filter every parent list to the pairs you can actually breed. There is no account to create and nothing is uploaded: the list never leaves the device, and the Palbox page clears it.

It shows the route rather than planning the whole project: every breeding page draws the direct path as a tree with both parents above the child, and each parent links to its own page, so a chain is walked one generation at a time. The Palworld Pal Generation Tracking guide covers recording each stage as you go.

Not as a prediction, and it does not claim to. The species is deterministic; passive skills, stat growth and a mutation are all rolled after the hatch is decided. The Palworld Pal Passive Skills guide gives the inheritance odds and the Palworld Pal Mutation guide covers the 1% mutation roll and the Cake that raises it.

No account, no install and no ads. The calculator runs in the page, so a search is one pick away, which is the whole reason Pal Breeding Calculator keeps no login, no save button and nothing to dismiss first.

Yes. The mode and the pair are written into the page address as you use the calculator, so the URL in the address bar is the result: copy it and the same pair opens in the same mode for whoever you send it to.

The source is PalCalc community game-data export (tylercamp/palcalc) + palworld.wiki.gg: a structured export of the shipped game data merged with the community wiki for the parts the export does not carry, such as partner skills and drop tables. That is 299 Pals and 44,851 precomputed parent pairs. The data changelog records what each import contained and when it ran.

Every refresh replays all 44,851 parent pairs against the game's own breeding table and compares the outcome with a reference implementation of the same algorithm. Nothing is published until those replays agree; the current import reports zero mismatches.

Three rules, applied in order: a fixed special combination, then two parents of the same species, then the average of the two hidden breeding ranks, floor((rank A + rank B + 1) / 2), with ties going to the lower index. The breeding formula guide sets the three rules out in order with worked examples.

No. The 44,851 pair rows are built once at import time and stored on the 299 Pals they belong to, so a page renders from stored data instead of running the formula per request. That is what keeps a page listing a thousand pairs as fast as one listing three.

Usually one of three things: a table older than 1.0, a calculator that averages ranks without checking the 138 fixed combinations first, or one that ignores the single gender-sensitive pair. The dataset here is Palworld v1.0 (build v28), last verified 2026-09-16, and both are printed on the page so a disagreement can be dated rather than argued about.

Three things, each labelled rather than filled in: no source publishes a per-Pal World Tree drop table, no element typings exist in the current export so element filters stay hidden, and 26 Pals hatch only from two of their own species. No percentage is printed where the game publishes none. The mutation and inheritance odds that do exist are the game's own rules, and the Palworld Pal Breeding Cost guide prices the resources a project needs.

The only state the calculator keeps is your Palbox, and it stays in your browser. What the site itself stores, and what it does not do with it, is set out in the privacy policy and the cookie policy rather than summarised here.

Pal Breeding Calculator is an independent, fan-made reference for Palworld 1.0 breeding, built and maintained by players who breed. It exists because the 1.0 update moved breeding combinations and the older published charts stopped matching the game. Corrections and questions go through the contact form.

No. Pal Breeding Calculator is unofficial and is not affiliated with, endorsed by or sponsored by Pocketpair, Inc. Palworld, the Pal names and designs, item names and the underlying game data belong to Pocketpair and their respective owners; they appear here to identify what each page is about, with no claim of ownership. The disclaimer states it in full.

Send it through the contact form with the page and the pair you were checking, and it is fixed in the next data pass rather than in a comment nobody reads. What was imported in each pass, and what was changed, is listed in the data changelog.

Whenever the game data moves: the table is re-imported, all 44,851 parent pairs are replayed against the rule set, and the version stamp updates with it. The site is currently on Palworld v1.0 (build v28), verified 2026-09-16, and that stamp is printed with the result on every page rather than kept on an about page alone.

Short quotes with a credit and a link are welcome. What the site wrote is the site's; Palworld and its assets are Pocketpair's; and a rights holder can ask for something to be taken down, which is what the copyright page sets out.

English, with Spanish in progress at qvemos.com/es. The translated pages carry the same data and the same answers; they are kept out of the index until the wording is finished, so a half-translated page is never served as the Spanish version of an English one. Every result on Pal Breeding Calculator is stated in English, whatever language the page around it uses.

It says so. Nothing on this site is estimated to fill a gap: a Pal with no cross-parent route says that, a drop table no source publishes stays empty, and a stat with no published rate prints no percentage. A stated gap is more useful than a plausible number that cannot be checked.
