Most people think of zodiac compatibility as a quick comparison between two sun signs — "Are Aries and Libra a good match?" In reality, Vedic astrology evaluates compatibility at a far deeper level. It examines the Moon sign (rashi), the birth star (nakshatra), the ascendant, and the placement of every planet across both charts. Two people who share the same sun sign pairing can receive very different scores because their Moon signs, Venus placements, and seventh-house lords tell a more nuanced story.

This tool performs a full birth-chart comparison, not a simplified sun-sign lookup. When you enter both sets of birth details — date, time, and place — the system calculates planetary longitudes, house cusps, and nakshatra padas for each person, then cross-references them using classical Vedic matching rules. The result is a multi-dimensional compatibility portrait that reflects emotional temperament, physical harmony, financial outlook, family dynamics, and long-term staying power.

At the core of the scoring system is Ashtakoot (eight-fold) kuta matching, which awards points across eight dimensions: Varna (spiritual outlook), Vashya (mutual influence), Tara (birth-star harmony), Yoni (physical compatibility), Graha Maitri (planetary friendship), Gana (temperament), Bhakoot (emotional bonding), and Nadi (health and progeny). Each kuta carries a different weight, and the combined total out of 36 gives a baseline compatibility figure that has been trusted across centuries.

Beyond the kuta total, the tool also evaluates planetary aspects, house overlays, and dasha-period alignment. The "Easy" view distills all of this into plain-language summaries and a single percentage so you can grasp the overall picture at a glance. The "Advanced" view breaks the result into individual kuta scores and planetary cross-aspects, allowing those with astrological knowledge to drill into exactly where the harmony — or friction — originates.

A high compatibility score — generally above 60 percent — indicates that the two charts share strong natural alignment in temperament, values, and life direction. Couples in this range tend to resolve disagreements more easily because the underlying planetary energies support mutual understanding. It does not mean the relationship will be effortless, but it does mean the cosmic foundation is sturdy enough to weather ordinary challenges.

A lower score does not condemn a relationship. It highlights specific areas where extra awareness and effort are needed. For example, a weak Graha Maitri score suggests differing mental wavelengths, which can be bridged through open communication. A low Bhakoot score points to potential emotional friction that conscious compromise can soften. The Advanced view makes these individual dimensions visible so you know exactly where to focus.

Zodiac compatibility is one lens among many. Factors like shared values, mutual respect, communication habits, and personal growth all shape a relationship in ways that no chart can fully capture. Use the score as a compass rather than a verdict — it illuminates tendencies and timing, giving you an informed starting point for deeper conversations about your partnership's future.
