Vedic Astrology has a unique system of determining the compatibility between two charts. Chart compatibility is determined by precise analysis of how the planetary positions in the charts compare and interact. Traditionally, the position of the Moon is considered the most important factor, and a simply scoring system based on the Moon alone has become very popular in India. This system is called the "Koota" system, as it expresses the degree of compatibility in "kootas" (points). This report indicates the compatibility rating of the partners on the basis of their birth stars and provides valuable insight about mutual relationships in the form of a compatibility score.

In determining compatibilty between two charts there is one more way, that is to see the 'graha Mythri' between the planets in each other horoscope.
