Is 70 Really the Best Age to Claim Social Security?

Deciding when to claim Social Security is one of the most important financial choices many Americans will make in retirement. While it’s often talked about like it’s a simple decision (claim early, at full retirement age, or wait until 7) the choice is actually more nuanced. The age you choose can affect not just your monthly check, but your lifetime income, tax situation, and overall financial security in retirement.

This article breaks down the real trade-offs behind Social Security claiming, including the benefits of waiting, the risks of delaying too long, and the factors that can subtly limit your options. By taking a hard look at health, work plans, family considerations, and timing, you’ll be better equipped to decide when claiming Social Security truly makes sense for you.

Your “Choice” Isn’t Always Absolute

While seniors generally have flexibility in choosing when to claim Social Security, that choice isn’t always as simple or universal as it sounds. Certain rules and personal circumstances can limit how much control you really have over the timing or affect whether claiming earlier or later actually works in your favor.

For example, if you claim Social Security before full retirement age and continue working, your benefits may be temporarily reduced under the earnings test if your income exceeds annual limits. In addition, married individuals may need to consider spousal and survivor benefits, since the timing of one spouse’s claim can affect the other’s lifetime income. Medicare is another factor: while you can delay Social Security until age 70, most people still need to enroll in Medicare at 65 to avoid late-enrollment penalties. Taken together, these factors mean that while you technically have options, the “right” choice often depends on work plans, marital status, health, and overall retirement strategy, not just age alone.

Generally speaking, if you wait until full retirement age (FRA), you’ll get your complete monthly benefit without a reduction.

There’s also the option to delay Social Security until age 70. For people born in 1943 or later, delaying past FRA increases benefits by about 8% per year (credited monthly) up to age 70.

With an FRA of 67, you have an opportunity to boost your monthly benefits by 24%, which may be a smart thing to do if you’re approaching retirement with very little money in the way of savings. And even if you have savings, there’s something to be said for having a guaranteed larger benefit for life.

But while there’s a clear upside to claiming Social Security at 70, there’s also a downside to consider. And it’s one that may make you change your mind about filing for benefits at 70.

You’re taking a risk

Some people will tell you that 70 is the best age to take Social Security because it gives you the most amount of money on a monthly basis. But what you may not realize is that a claim at age 70 won’t necessarily result in the most amount of money on a lifetime basis.

When you file at age 70, you miss out on many years of payments. And also, you run the risk of not living long enough to make up for those years of lost payments.

That’s why it’s important to figure out your break-even age in the context of claiming Social Security. That’s the age when you’d get the same lifetime benefit from the program whether you file sooner rather than later.

As an example, if you’re eligible for $2,000 in Social Security at an FRA of 67, waiting until age 70 gives you $2,480 a month instead. If you’re thinking of waiting until age 70 to sign up, it’s important to know that 82 and 1/2 is your break-even age. At that age, you get the same lifetime payout – in this case, $372,000 – regardless of whether you sign up for benefits at 67 versus 70.

From there, the question to ask yourself is whether you think you’ll live past age 82 1/2 — or whether you want to take the risk. If you’re not sure, then 70 may not be the best age to claim Social Security for you. You may decide you’re safer starting to get your money sooner.

It pays to get help with this big decision

Clearly, there’s a lot riding on your Social Security filing age. So, if you’re not confident in your ability to choose a filing age on your own, you may want to consult a financial advisor for help. An advisor can help you run the numbers and help you make a smart decision based on factors that include your savings, retirement goals, and life expectancy.

In the course of those discussions, though, be honest about the state of your health. If you’re nearing retirement and it isn’t great, filing at age 70 could be a mistake.

Also take your family history into account. The fact that your parents lived well into their 80s doesn’t guarantee that you will as well. But if your parents passed away at a young age, it may be a sign that claiming Social Security at 70 is the wrong choice.
