What Is Kundli Matching?
Kundli matching (also called Guna Milan or Ashtakoot Milan) is the traditional Vedic astrology system for assessing marriage compatibility. It compares both people's Moon nakshatras across eight specific factors (kootas), each assigned a point value, producing a maximum score of 36 gunas. A score of 18+ is traditionally required for marriage consideration; 28+ is considered auspicious; 32+ is considered exceptional.
This system has been used in Indian culture for marriage decisions for centuries and remains the most widely used compatibility framework in Vedic astrology today. It is powerful, systematic, and has stood the test of significant cultural validation over many generations.
But it was designed for a different era — one in which marriage was a family decision made between communities rather than an individual choice made between two complete, psychologically complex people. The Ashtakoot system captures one dimension of compatibility with great precision. It misses five others.
Fliyp's Compatibility analysis includes the full Ashtakoot calculation plus five additional layers that traditional Kundli matching does not address.
What Ashtakoot Does Well
Before examining what it misses, it is worth understanding what the Ashtakoot system genuinely captures:
Nadi (8 points) — Constitutional Compatibility
Nadi is the most heavily weighted factor. Each of the 27 nakshatras belongs to one of three nadis — Vata (Adi), Pitta (Madhya), or Kapha (Antya). When both partners share the same nadi, Nadi Dosha arises, traditionally associated with health complications and difficulty with progeny. This is a genuine constitutional signal — it relates to fundamental energy-body compatibility at the cellular level.
Why it matters: Partners with the same nadi may share constitutional health vulnerabilities, which can amplify rather than balance each other. Different nadis tend to create complementary constitutional energy.
Bhakoot (7 points) — Life Direction and Prosperity
Bhakoot examines the Moon sign relationship between the two people. Certain sign relationships (6-8, 2-12 positions) are considered unfavourable, indicating one person's prosperity may come at the cost of the other's, or that the two life directions are fundamentally at odds.
Why it matters: This factor captures something about whether the two people's life trajectories support or compete with each other over the long run.
Gana (6 points) — Temperament Match
Each nakshatra belongs to one of three ganas — Deva (divine, gentle), Manushya (human, moderate), or Rakshasa (intense, forceful). Compatible gana pairings produce natural temperamental resonance; incompatible pairings (especially Deva-Rakshasa) create persistent temperamental friction.
Why it matters: Temperament is one of the most underrated compatibility factors. Two people can love each other deeply and still exhaust each other because their fundamental temperamental rhythms conflict — one needing gentleness and peace, the other needing intensity and conflict as a form of engagement.
Graha Maitri (5 points) — Mental Compatibility
This factor assesses the natural relationship between the ruling planets of each person's Moon sign. When the Moon sign lords are natural friends, mental and intellectual compatibility flows naturally. When they are natural enemies, the two minds approach problems differently in ways that can produce persistent misunderstanding.
Yoni (4 points) — Physical and Intimate Compatibility
Each nakshatra is assigned a yoni (animal symbol). Compatible yoni pairings indicate natural physical harmony; incompatible pairings indicate friction in physical and intimate dimensions.
Tara (3 points) — Health and Fortune
This factor counts the nakshatra distance between both people's Moon nakshatras and assesses whether the relationship supports health and overall wellbeing for each person.
Vashya (2 points) — Natural Influence Dynamic
Certain Moon signs have a natural influence relationship — one sign naturally draws the other. This factor captures the power dynamic and mutual attraction quality.
Varna (1 point) — Spiritual Compatibility
This factor (the lightest weighted) relates to spiritual evolution level and path compatibility — whether both people are at compatible stages of dharmic development.
What Ashtakoot Does Not Include
For all its strengths, the Ashtakoot system was designed to assess Moon nakshatra compatibility — one specific layer of two people's charts. It does not include:
The Ascendant Layer
Your ascendant is arguably the most important point in your birth chart for personality and daily functioning. Two people can have excellent Ashtakoot scores while having deeply incompatible ascendants — meaning their Moon signs resonate but their day-to-day personalities create persistent friction.
A Cancer Moon person with a Scorpio ascendant (intense, private, emotionally guarded) may have a high Ashtakoot score with a Cancer Moon person with a Sagittarius ascendant (expansive, public, emotionally expressive) — but their daily interaction styles will be persistently discordant despite Moon resonance. Ashtakoot does not capture this.
Fliyp's Compatibility assesses ascendant compatibility as a separate layer, measuring elemental alignment, modality compatibility, and the natural dynamic between the two ascendant lords.
Venus Compatibility
Venus is the primary planet of love, beauty, values, and pleasure. Sun sign compatibility tools typically assess Venus; Ashtakoot ignores it entirely. But Venus describes what a person finds beautiful, what they value in a partner, and how they give and receive affection — arguably the most directly relationship-relevant planetary factor.
Two people with Venus in deeply incompatible signs may have excellent Ashtakoot scores while finding each other's relationship styles fundamentally unsatisfying. Venus in Scorpio seeks depth, transformation, and intensity in love; Venus in Aquarius seeks freedom, intellectual connection, and unconventionality. These are genuinely different love languages that Ashtakoot does not capture.
Fliyp's Compatibility calculates Venus sign compatibility as a dedicated layer.
The 7th House Configuration
The 7th house is the house of partnership, marriage, and committed relationships in Vedic astrology. Ashtakoot ignores both people's 7th house entirely. But the quality of a person's 7th house — what planets occupy it, the dignity of the 7th house lord, the presence or absence of Mangal Dosha — fundamentally determines their natural capacity for and experience of committed partnership.
A person with a strong Jupiter in the 7th house has a natural gift for partnership and sees relationships as expansive and growth-oriented. A person with Saturn in the 7th house approaches partnership with caution, takes it seriously but slowly, and experiences it as a domain requiring sustained discipline. These different 7th house configurations create different partnership dynamics regardless of Ashtakoot score.
Fliyp's Compatibility includes full 7th house analysis for both partners.
Current Dasha Period Alignment
Two people may have excellent long-range chart compatibility but be in very different dasha periods at the time of their relationship — one in a Venus Mahadasha (highly relationship-oriented) and one in a Saturn Mahadasha (highly focused on individual karmic work and discipline). This temporal factor can explain why two well-matched people consistently miss each other's timing or feel out of sync despite genuine connection.
Ashtakoot is a static calculation — it does not account for where each person is in their dasha cycle at the moment of the relationship. Fliyp's Compatibility includes a dasha alignment assessment.
The Synastry Layer
Synastry is the assessment of how one person's planets interact with the other person's chart positions — not just whether the two charts are independently strong, but how they interact. Does Person A's Jupiter form a beneficial aspect to Person B's 7th house lord? Does Person A's Mars oppose Person B's natal Moon (creating tension in emotional-action dynamics)? Does Person A's Saturn conjunct Person B's Venus (creating a serious, possibly restrictive dynamic in how pleasure and value are expressed in the relationship)?
Traditional Kundli matching does not include synastry — it only compares Moon nakshatras. Fliyp's Compatibility includes a synastry assessment of the most significant inter-chart aspect relationships.

When Traditional Kundli Matching and Fliyp Compatibility Disagree
High Ashtakoot, lower Fliyp score: The Moon nakshatras resonate deeply — there is real emotional and constitutional compatibility. But one or more of the additional layers introduces friction: perhaps incompatible ascendants create daily interaction challenges, or Venus incompatibility creates different love language styles. This is a relationship that feels emotionally right but requires more conscious bridging in day-to-day expression.
Lower Ashtakoot, higher Fliyp score: The Moon nakshatras are not ideally matched — perhaps a Nadi Dosha or Bhakoot concern. But the ascendants are complementary, Venus signs are harmonious, the 7th houses are both strong, and the synastry shows supportive inter-chart interactions. This is a relationship where the traditional flag is real but is offset by other genuine strengths.
Agreement between both: When Ashtakoot is high and Fliyp's additional layers also score well, the compatibility is genuinely multi-dimensional — the relationship has natural ease at the constitutional level (Moon), the personality level (ascendant), the values level (Venus), the partnership structure level (7th house), and the timing level (dasha). These relationships tend to be both naturally easy and deeply fulfilling.
Frequently Asked Questions
Q: Should I rule out a relationship if Ashtakoot score is below 18? Traditional guidance is that below 18 gunas warrants caution. But context matters significantly — the quality and dignity of the planets involved, the presence of cancellation factors for doshas, and the strength of the other compatibility layers all modify this. A relationship with 15 Ashtakoot gunas but excellent ascendant compatibility, Venus harmony, and strong 7th houses may be more viable than one with 24 gunas but multiple other layer conflicts.
Q: Does Fliyp replace the need for a traditional astrologer for marriage decisions? Fliyp provides the most complete automated compatibility analysis available. For a major life decision like marriage in a cultural context where astrological compatibility is significant, a skilled Vedic astrologer who can also assess family charts, muhurta (auspicious timing), and additional factors adds value beyond automated calculation. Fliyp is a powerful foundation; human expertise adds the contextual interpretation layer.
Q: What is Nadi Dosha cancellation? Traditional astrology includes several conditions under which Nadi Dosha is considered cancelled: when both partners share the same Moon sign, when both share the same nakshatra, or when Jupiter is in the 7th house for both charts. Fliyp flags Nadi Dosha and applies standard cancellation rules automatically.
Q: Can compatibility be improved over time? Astrological compatibility describes the natural quality of the two charts' interaction — it does not change. What changes is both people's capacity to understand and work with the dynamics their charts describe. A challenging compatibility pattern, once understood, can be navigated with skill; the same pattern without awareness creates repeated unconscious conflict.
