3 Top Reasons Taking Social Security at Age 70 Is a Mistake

For many seniors, the most important decision they'll make is deciding when to begin taking their retirement benefit from Social Security. That's because, according to the Social Security Administration (SSA), 62% of retired workers currently lean on their benefit to account for at least half their monthly income, with just over a third reliant on the program for virtually all of their income.

Unfortunately, this often isn't a cut-and-dried decision, because there is no perfect guide to ensure you'll make the best possible choice.

Although benefits can begin at age 62 for retired workers, that may not be the best time to begin taking them. For each year you wait on taking benefits, your eventual payout grows by about 8%, up until age 70. All things being equal -- earnings history, work history, and birth year -- those taking benefits at age 70 could earn as much as 76% more per month than individuals taking their benefits as soon as they turn 62.

This idea that waiting to take your payout can boost your eventual take-home from Social Security is powerful. It's a big reason behind a growing number of people waiting until their full retirement age (FRA) -- or perhaps even longer -- to begin taking their benefit.

Your full retirement age is the age at which the SSA deems you eligible to receive 100% of your payout, as determined by your birth year. For most people, full retirement age will be 66, 67, or somewhere in between. Claiming benefits at any point before that means accepting a permanent reduction to your monthly payout, whereas waiting until after your FRA can increase your benefit above 100%.

Claiming at 70 might not be the best idea

Although a larger monthly payout probably sounds great -- and for some people, it truly is the best decision they can make – there are a number of reasons that waiting until 70 and maximizing your monthly benefit is a mistake.

1. You may not make it to your claiming age

For starters, there's no guarantee that you'll live to see age 70. Don't get me wrong: We've seen a growing number of Americans living long enough to claim a Social Security benefit. And those who do make it to 65 are living an average of about two decades longer. But these are averages, and everyone's personal health situation is unique.

If you have a chronic condition, such as heart disease or diabetes, or have dealt with cancer, longevity data shows the deck is stacked against you to outlive the average life expectancy in the United States of just over 78 years. Waiting until age 70 would mean giving up as many as eight years in which benefits could have been collected, albeit at a reduced rate. If you take your payout at age 70 and don't wind up living to around 80 years old, the lifetime benefits you accrue from the program could be lower than what you'd have received had you begun taking a reduced payout at age 62.
