# How does an online matchmaking calculator determine 36 Guna compatibility? In Vedic astrology (Jyotish), evaluating long-term marital harmony relies heavily on Ashta Koota Milan—a proven 36 Guna scoring system that assesses emotional, psychological, physical, and genetic compatibility between partners. Traditionally, computing these scores required manual ephemeris lookups and complex mathematical cross-referencing. Today, using an arc-second accurate digital **[matchmaking calculator](https://astroma.co/matchmaking)** on astroma, couples can analyze their 36 Guna breakdown instantly, objectively, and completely free of charge. ## The Eight Columns of Ashta Koota Milan The 36 Guna framework evaluates eight distinct compatibility layers (Kootas), assigning progressive weight to each factor based on its impact on long-term relationship stability. --- > A high Guna score indicates strong energetic alignment, but complete marital synastry also requires analyzing 7th house lords, Navamsha (D9) charts, and active Dasha periods. An AI-powered matchmaking calculator evaluates all eight Kootas simultaneously by cross-referencing the natal Moon sign (Chandra Rashi) and exact Moon Nakshatra placements of both individuals: | Koota Factor | Maximum Points | Core Astrological Focus | Relationship Significance | | --- | --- | --- | --- | | **Varna** | 1 Point | Spiritual & Ego Alignment | Measures mutual respect and psychological adaptability | | **Vashya** | 2 Points | Mutual Attraction | Assesses natural interpersonal magnetism and influence | | **Tara** | 3 Points | Birth Star Compatibility | Evaluates health, prosperity, and karmic well-being | | **Yoni** | 4 Points | Intimacy & Temperament | Measures physical compatibility and mutual comfort | | **Graha Maitri** | 5 Points | Intellectual Friendship | Assesses mental rapport, communication, and shared values | | **Gana** | 6 Points | Behavioral Nature | Evaluates temperamental alignment (Deva, Manushya, or Rakshasa) | | **Bhakoot** | 7 Points | Emotional & Material Growth | Analyzes domestic prosperity, family welfare, and emotional stability | | **Nadi** | 8 Points | Physiological & Genetic Health | Evaluates core vitality, nervous system alignment, and lineage balance | ## How AI Calculators Determine 36 Guna Scores When you input birth parameters into an online matchmaking calculator, the engine executes complex astronomical algorithms in milliseconds to deliver precise scores: 1. **Arc-Second Longitude Mapping**: Calculates the exact sidereal position of the Moon in both charts down to the arc-second to determine the exact Nakshatra and Pada (quarter). 2. **Koota Matrix Cross-Referencing**: Evaluates the relative positions of both Moons to assign points across all eight categories, adding up to a total score out of 36 points. 3. **Dosha Detection**: Identifies critical compatibility exceptions, such as Nadi Dosha, Bhakoot Dosha, or Gana Dosha, while checking for classical astrological cancellations (Dosha Bhanga). Generally, a total score of 18 points or higher is considered favorable for marital compatibility, provided major Doshas are mitigated by strong planetary placements. ## Step-by-Step: Evaluating Your Compatibility on Astroma Checking your 36 Guna breakdown on astroma requires no registration or technical background.
