Claiming Social Security at 66
The short answer
Claiming at 66 pays 93.3% of your full benefit, permanently. On a $2,000 monthly full benefit that is $1,867 a month, or $22,404 a year. That is $1,596 a year less than waiting to 67, and the reduction never reverses.

Totals are cumulative benefits collected by that age, in today's dollars. Social Security rises with inflation each year, so in real terms the payment is level for life and the comparison is simply a bigger cheque against fewer years of it.
The break-even, and why it is usually quoted wrong
Comparing 66 against 67 on total dollars collected, the later claim overtakes the earlier one at about age 82. Live past that and waiting paid. Die before it and claiming earlier did.
That calculation treats a dollar collected at 85 as identical to a dollar collected at 66, which nobody believes about any other financial decision. Discount each year back at 3% real, which is roughly what the money would have earned sitting in the portfolio instead, and the crossover moves to about age 86.
Those 4 years are not a rounding difference. They are the gap between a decision that looks obvious and one that is genuinely close, and almost every break-even figure published online omits them.
What the arithmetic cannot settle is how long you will live, and that is the actual variable. A break-even at 82 is a good deal for someone whose parents reached 95 and a poor one for someone managing a serious condition. Longevity is the input, and it is the one nobody knows.
Worth knowing: for a married couple this is two decisions rather than one, and they are not symmetric. When one spouse dies the survivor keeps the larger of the two benefits, so delaying the higher earner's claim buys protection that lasts through both lifetimes. The lower earner's claim is closer to a pure break-even calculation.
Common questions
How much is Social Security at 66?
On a full benefit of $2,000 a month, claiming at 66 pays $1,867 a month, or $22,404 a year. That is 93.3% of the full amount, and the percentage is what matters: it applies to whatever your own benefit turns out to be.
Is claiming at 66 a mistake?
Not automatically. Claiming at 66 locks in 93.3% of your full benefit permanently, which costs $1,596 a year against waiting to 67. It is the right call if you need the income, if your health or family history points to a shorter life, or if drawing benefits keeps you from selling a depressed portfolio early in retirement.
What is the break-even age for claiming at 66?
Around 82 in total dollars collected, comparing 66 against 67. Discount each year back at 3% real and the crossover moves to about 86, because a dollar at 85 is worth less than a dollar today. Most break-even calculators skip that adjustment, which makes delaying look better than it is.
Does delaying still make sense if I retire before 66?
Often yes, and it is a separate decision from when you stop working. Retiring at 62 and claiming at 70 means eight years funded from the portfolio, which is a real cost. What you buy is a larger benefit that is inflation-adjusted and lasts as long as you do, which is the closest thing to longevity insurance most people can get.
