Get time on your side
Retirement savings grow largely because of compound interest: The money put away in the early years will generate interest earnings of its own with each passing year. Because Alice has started investing at the beginning of her career, her savings will have more time to grow.
Draw up a plan
How much is enough in retirement? Everyone’s answer is different and personal, but consider the 80% rule. That says you should plan to save enough so that for each year of your retirement, you can spend 80% of the amount you made in your last year working without exhausting your retirement fund.
Maximize your retirement benefits
If your employer offers a 401(k) and will match your contribution, put in enough to get the full match. So long as you can afford it, it’s getting the most “free” money available to you.
