Yoni Matching Calculator

Each of the 27 nakshatras is classically assigned an animal symbol — 14 animals in total, each appearing as either the "male" or "female" form of that species across two nakshatras. Yoni Koota (worth 4 of the full 36 Ashtakoota points) reads how well these two animal symbols pair, drawing on centuries-old classifications of natural affinity and enmity between species.

Ayanamsa: Lahiri (Chitrapaksha) · Rule: same animal Yoni = 4/4, classically opposed pair (e.g. Cat/Rat, Cow/Tiger, Snake/Mongoose) = 0/4, otherwise 2/4

What the Yoni Symbol Represents

Yoni is classically read as governing physical nature, instinctual compatibility, and intimate connection between partners — the animal symbolism is a shorthand for temperament and drive that predates and sits alongside the more abstract Gana and Graha Maitri kootas.

Same, Neutral, or Opposed

The same animal on both sides scores the full 4 points, a classically opposed pair (natural predator-prey relationships like Cat/Rat, Cow/Tiger, or Snake/Mongoose) scores 0, and any other different, non-opposed pairing scores 2 — a solid middle ground reflecting neither strong natural affinity nor active opposition.

The Fourteen Yoni Animals

Horse, Elephant, Sheep, Serpent, Dog, Cat, Cow, Buffalo, Tiger, Hare, Monkey, Mongoose, Lion, and Rat — each nakshatra is fixed to one of these fourteen, with several animals (like Serpent, Buffalo, Sheep, and Cat) shared across more than one nakshatra.

Yoni Matching Calculator FAQs

What is Yoni Koota?
A classical Ashtakoota factor that compares the animal symbol assigned to each partner's birth nakshatra, reading physical and instinctual compatibility through the natural affinity or opposition between those two animals.
How many points does Yoni Koota carry?
4 of the full 36 Ashtakoota points.
What does it mean if our animal symbols are classically opposed?
It scores 0 points on this specific koota, traditionally read as a friction point in physical/instinctual compatibility — though it's one of eight factors, not a standalone verdict on the whole relationship.
Why do some nakshatras share the same animal?
With 14 animal symbols spread across 27 nakshatras, several animals are necessarily repeated — sharing the same Yoni animal as your partner is what scores the maximum 4 points on this koota.
Is a 0 on Yoni Koota a serious problem?
It's a specific classical flag worth being aware of, but represents only 4 of the full 36 Ashtakoota points — a fuller compatibility assessment weighs it alongside the other seven kootas rather than in isolation.
