Astrologically, one can try to recognize the potential wealth of a native from a study of the correct horoscope. Normally, the 2nd house, its lord, planets associated therein and the aspects to it are considered relevant. Similarly, the 11th house is considered in the same way for gains from inheritance or ancestral property. The strength of the 10th house, its lord and karakatatva planets can throw light on the native's efforts to sustain himself financially.
Here according to Nadi Astrology, a lot of importance is given to Saturn and aspects of other planets and luminaries on Saturn. The Karaka planet is Jupiter as per Vedic Astrology.
A strong lagna or ascendant (rising sign at birth) and strong 2nd and 11th lords can mitigate the severity of one’s economic condition to a great extent. Of course, the operating dasa (planetary period) too needs to be examined with reference and relation to the 2nd and 11th houses occupier(s), lord, aspects etc.
