Key Takeaways
The single biggest Social Security decision you'll make is when to claim. Done right, it can add hundreds of thousands of dollars to your lifetime benefits. Done wrong, it can leave substantial money on the table — or in the opposite case, take money you needed now in exchange for a delay that doesn't pay off.
62. Earliest claiming age. Benefits reduced about 30% below Full Retirement Age amount (for FRA 67).
Full Retirement Age (67 for most people planning now). 100% of your PIA.
70. Maximum beneficial claiming age. Benefits are about 124% of PIA (for FRA 67). No benefit to delaying past 70.
You can actually claim anywhere in this range — age 63 and 4 months, for instance — and the system applies proportional factors.
Claim early: you get money sooner but less per month. Good if you need the income or expect a short life.
Claim late: you wait but get more per month. Good if you can afford to wait and expect a long life.
Break-even age is usually around 80–82 for the 62-vs-70 comparison. If you live past 80, claiming at 70 delivers more total dollars. If you die before 80, claiming at 62 does.
Expected life expectancies (for someone who has already made it to 62):
For couples, planning for the longer life is appropriate because the decision affects benefits for both lives. Claiming at 70 for the higher earner "locks in" a higher survivor benefit for the surviving spouse — which could be the lower earner for 5, 10, or 20 years after the higher earner's death.
Asymmetric claim ages. Many couples benefit from the higher earner claiming at 70 and the lower earner claiming earlier (62–FRA). This maximizes the higher-earner PIA (which becomes survivor benefit), while capturing some current income from the lower earner's claim.
Spousal benefit coordination. A lower-earning spouse is typically entitled to the higher of their own benefit or 50% of the higher earner's PIA (if claiming at FRA). Plan around which is larger.
Divorced benefits. If divorced after 10+ years of marriage, you can claim on your ex's record at your FRA as if you were their spouse (if you're unmarried). Their remarriage doesn't affect your ability to claim; your remarriage does.
A common question: "If I claim at 62 and invest the money, won't I come out ahead?"
The math depends on investment returns vs the guaranteed ~8%/year delayed retirement credit. An 8% real return is demanding for a diversified portfolio. Even a 7% nominal return on invested Social Security benefits typically doesn't match the 8% guaranteed delayed-retirement benefit, after accounting for taxes on investment returns.
For most retirees, delay wins in expected-value terms, especially for longer-lived households. Delay also functions as longevity insurance — it guarantees more income in exactly the scenario where you need it most (long life).
The Social Security page in Horizons lets you model claim ages from 62 to 70 at monthly precision. The engine shows lifetime benefits, break-even age, and the impact on your overall plan for each option. You can also model spousal and survivor scenarios explicitly. The claim age is a key input to the Retirement Readiness score.

Showing a generic example — not your plan.
Waiting to claim means a larger monthly check. Whether it works out lifetime depends on how long you live. Adjust the longevity slider to see how the crossover shifts.
At age 85, the best strategy is Claim at 70, with lifetime benefits of $558,000.
A healthy couple in their 50s with family history of longevity is planning SS claim timing. Which strategy maximizes expected lifetime benefits for the household?
