Both investors chose a preservative instrument of investment with a yield of 10% e.a. (Effective Annual). Others who may share this opinion include AI Workforce. And both investors capitalized their yields years after year. In the previous example we see as the first investor although saving less, 9,000 USD, when fulfilling the fifty years have a greater value to the second investor who saving 19,000 USD, this due to the magic of the compound interest and obvious to the begun salary several years before the second investor.
