Social Security Break-Even
Between 62 and 70 the monthly benefit varies by about 77%, so the choice is really a bet on longevity. This prices every claiming age against your own full retirement age, applies cost-of-living adjustments from 62 rather than from your claim date — which most models get wrong, in the direction that penalizes waiting — and reports the break-even both in raw dollars and discounted, because those two answers can be years apart.
When to claim
Enter your monthly benefit at full retirement age and your year of birth, then press Calculate.
Your benefit
The figure to enter is your primary insurance amount — the monthly benefit at full retirement age. On your Social Security statement it is the one against your FRA, not the ones against 62 or 70.
Create an account at ssa.gov to see yours. If you are years away, the statement's estimate assumes you keep earning at your current rate; if you plan to stop earlier, it will overstate the figure.
Your birth year sets full retirement age, which is the reference point the entire reduction and credit schedule is defined against.

How to compare them
Life expectancy is what the whole decision turns on. Use a realistic figure for someone already 62 and in your health — not life expectancy at birth, which is much lower and would push you toward claiming early for the wrong reason. A 62-year-old in average health today has a good chance of reaching their late eighties.
The discount rate is the interesting one. At 0% a dollar at 90 counts the same as a dollar next month, which is the comparison every article prints. Setting it to something realistic pushes the break-even later — sometimes by years — because waiting means spending your own money first.
Realistic for someone already 62 — not life expectancy at birth
0% compares raw dollars. Anything higher values money sooner.
The claiming age the break-evens are measured from
Cost-of-living adjustments are applied from age 62 whether or not you have claimed, which is how the program actually works. Waiting does not forfeit them — it compounds them into a larger base.

How to use it
The figure to enter is your primary insurance amount — the monthly benefit at full retirement age. On your Social Security statement it is the one printed against your FRA, not the ones against 62 or 70. Create an account at ssa.gov to see yours.
Then set life expectancy honestly. Use a realistic figure for someone who has already reached 62 and is in your health — not life expectancy at birth, which is several years lower and would push you toward claiming early for a reason that doesn't apply to you.
Finally, try it once with a discount rate of 3–5%. That is where the received wisdom and the honest answer come apart, and seeing both is the point of the tool.

The COLA detail most tools get wrong
Cost-of-living adjustments are applied to your benefit from the year you turn 62, whether or not you have claimed. Waiting does not forfeit them. They compound quietly into a larger base, and then the delayed retirement credits are applied on top of that.
A model that only starts applying COLAs at the claim date understates what a late claimer receives, every single month, for the rest of their life. It moves the break-even earlier and makes waiting look worse than it is — in exactly the direction most people are already inclined to go.
This tool applies them from 62 for every claiming age, which is how the program actually works. It is the single most consequential modeling choice on this page, and it is why the break-evens here may sit later than ones you have seen elsewhere.
Why there are two break-evens
The familiar answer — somewhere around 78 to 82 — comes from adding up every payment and asking when the totals cross. That calculation quietly assumes a dollar received at 88 is worth exactly the same as a dollar received next month.
It isn't. Waiting until 70 means funding those eight years from your own savings — money that would otherwise have stayed invested, or that you might have wanted to spend while you were well enough to enjoy it. Applying a discount rate prices that, and it pushes the break-even later, sometimes by several years.
Neither figure is the right one. They answer different questions: one is about maximizing total lifetime income, the other about what the choice is worth to you today. The tool reports both, and tells you when they disagree about which age wins.
Assumptions and limits
- The biggest limitation: this models one person. For a married couple, the higher earner's claiming age also sets the survivor benefit, which is paid for as long as either spouse lives. That is usually a far stronger argument for delaying than any break-even here, and it is not modeled.
- Full retirement age comes from the statutory table by birth year. Reductions and delayed retirement credits use the published monthly rates, and credits stop at 70 — there is never a reason to wait longer.
- Not modeled: the earnings test that withholds benefits if you keep working before full retirement age, income tax on benefits, Medicare premiums deducted from the payment, IRMAA surcharges, or spousal and divorced-spouse benefits.
- Life expectancy is the input that decides this, and it is the one nobody knows. Treat the break-even as a threshold to judge yourself against, not a prediction.
- An estimate for planning. Not financial advice, and not a substitute for the Social Security Administration's own figures.
