Final answer:
Financial experts suggest saving around 15% of gross income, which provides a substantial retirement fund and aligns with historical personal savings rates.
Step-by-step explanation:
Financial experts generally recommend saving a portion of one's gross income to ensure financial stability and prepare for retirement.
While personal savings rates have varied over time, current economic advice suggests that saving around 15% of one's income may offer a comfortable retirement, allowing one to live with 60-80 percent of their pre-retirement income.
It is also advisable to have an emergency fund equivalent to at least three to six months of one's income. Comparative studies show that America's saving rates are lower than the global average.
