How much should you be saving?

If retirement is decades away, setting a specific goal amount is probably unnecessary. For now, focus on:

1. Immediately saving at least enough to get the full match offered by your employer plan, if you have one. This is free money—don't let it pass you by.
2. Working your way up to 12%–15% of your pay, including any employer match. For example, you could increase your savings rate 1% every year until you reach your target rate. This should get you in the ballpark of what you'll need.

Two big factors weigh heavily on your retirement savings needs: how many years you're going to spend in retirement and how much you're going to need to withdraw each year.

Plan to spend at least 30 years in retirement—longer if you think you'll retire early. Medical advances are consistently extending the average lifespan.

Even if you don't plan to retire early, illness or other responsibilities could prevent you from working as long as you expected, extending your retirement on both ends.

Figuring out how much you're going to withdraw each year can also be a little tricky.

After you estimate your expected budget—which will depend on the lifestyle you expect to live in retirement—you'll need to take into account other income (like Social Security and any pensions or rental income you're expecting, for example) and calculate the difference.
