Several experts recommend saving 20% of your income every month. According to this analysis, which is known as the popular 50/30/20 rule, you should reserve 50% of your budget for essentials like rent, food and essentials, 30% for discretionary spending, and at least 20% for savings. Merely saving money allows you to put away part of your earnings regularly, but earns a lower return although with lower risk. On the other hand, investing allows you to earn a higher return, but you take on the risk of loss in order to do so. Experts say you should save an amount equal to six months of expenses before you start investing. Some experts advise an eight-month emergency fund because that's about how long it takes an average person to find a job if you lose one and this amount can cover your expenses.
