For example, if a real estate investor earns twenty percent on an investment, they divide 69 by the 20 percent return and add 0.35 to the result.
Your $500,000 can give you about $20,000 each year using the 4% rule, and it could last over 30 years. The Bureau of Labor Statistics shows retirees spend around $54,000 yearly. Smart investments can make your savings last longer.
