I Used to Think 70 Was the Best Age to Claim Social Security Benefits. Here's Why I'd Now Rather Claim at 62.

One of the more important decisions anyone makes as they near retirement is deciding when to claim Social Security benefits. It's not a decision that should be glossed over, as it permanently affects your monthly benefits. This could matter a lot for people who plan to rely heavily on Social Security in retirement.

I used to think claiming at 70 was the better route because of the increased monthly benefits. However, after some thought and perspective, I now believe claiming at 62 is a great go-to for many people. Let's take a look at why.

How your benefits are affected by when you claim

When claiming Social Security, there are three ages to be aware of: your full retirement age, 62, and 70.

Your full retirement age is when you're eligible to receive your primary insurance amount (PIA). Think of this monthly amount as your baseline around which everything else revolves. Below are full retirement ages based on your birth year:

The second noteworthy age is 62 because that's the earliest you can claim Social Security benefits. However, claiming before your full retirement age will permanently reduce your monthly benefit.

If you're within 36 months of your full retirement age, Social Security will reduce your benefits by 5/9 of 1% monthly. Each additional month after 36 will further reduce them by 5/12 of 1%.

Assuming your full retirement age is 67, your monthly benefit will be reduced by 20% if you claim at 64 and 30% if you claim at 62.

Delaying benefits past your full retirement age will increase them by 2/3 of 1% monthly (8% annually), which is why 70 is the third noteworthy age. It's the latest you can delay benefits and still get the monthly increase, so it's generally thought to be the latest you should claim Social Security.

Once again, assuming your full retirement age is 67, delaying benefits until you reach 70 means you can expect a roughly 24% increase from your PIA.

Smaller for a longer time or larger for a shorter time?

When deciding between two ages to claim Social Security, I always encourage people to look at their breakeven age. That's the age when the total benefits received from claiming Social Security at one age equal those of another age.

To see it in action, let's assume someone is eligible to receive $2,000 in monthly benefits at their full retirement age. This means they receive around $1,400 by claiming at 62 and $2,480 by claiming at 70.

Keeping that in mind, here are the total benefits they would've received by certain ages.
