Before you claim Social Security, run the numbers on at least 3 claiming ages — the difference between claiming at 62 vs. 70 can exceed $100,000 in lifetime benefits. This is one of the biggest financial decisions you’ll make in retirement, and it’s permanent.

8 Things to Know Before Claiming

# Key Point Why It Matters
1 Claiming early permanently reduces your benefit 62 = 70% of full benefit; no way to undo it
2 Delaying past FRA earns 8% per year (up to age 70) Guaranteed 8% return — hard to beat
3 Working while claiming before FRA reduces benefits Earnings test withholds benefits above $23,400
4 Social Security may be taxable Up to 85% of benefits are taxed if combined income exceeds thresholds
5 Spousal benefits have their own rules Can claim up to 50% of spouse’s FRA benefit
6 Survivor benefits matter for couples The higher earner’s benefit determines what the surviving spouse gets
7 Your earnings record has 35 years Fewer than 35 working years = zeros that lower your average
8 You can undo your claim within 12 months Withdraw application and repay benefits within 12 months to restart

Benefit by Claiming Age

Claiming Age % of Full Benefit Monthly Benefit (FRA = $2,500) Annual Benefit Cumulative by Age 85
62 70% $1,750 $21,000 $483,000
63 75% $1,875 $22,500 $495,000
64 80% $2,000 $24,000 $504,000
65 86.7% $2,167 $26,004 $520,080
66 93.3% $2,333 $27,996 $531,924
67 (FRA) 100% $2,500 $30,000 $540,000
68 108% $2,700 $32,400 $550,800
69 116% $2,900 $34,800 $556,800
70 124% $3,100 $37,200 $558,000

If you live past 82-83, delaying to 70 pays the most. If health is poor, claiming earlier may be better.

Breakeven Ages

Claiming Strategy Breakeven Age (vs. 62)
Claim at 67 vs. 62 ~78
Claim at 70 vs. 62 ~82
Claim at 70 vs. 67 ~83

If you live past the breakeven age, delaying wins. Average life expectancy at 65 is 85 for men and 87 for women.

Earnings Test (Working While Claiming)

Situation Rule
Under FRA all year $1 withheld for every $2 earned above $23,400 (2026)
Year you reach FRA $1 withheld for every $3 earned above $62,160 (months before FRA)
FRA or older No earnings limit — keep full benefits while working
Withheld benefits Added back after FRA — increases your monthly benefit

Taxation of Social Security Benefits

Combined Income* % of Benefits Taxable
Under $25,000 (single) / $32,000 (married) 0%
$25,000-$34,000 (single) / $32,000-$44,000 (married) Up to 50%
Over $34,000 (single) / $44,000 (married) Up to 85%

Combined income = Adjusted gross income + nontaxable interest + 50% of Social Security benefits.

Spousal and Survivor Benefits

Benefit Type Amount Key Rules
Spousal benefit Up to 50% of spouse’s FRA benefit Must be married 1+ year; doesn’t reduce spouse’s benefit
Ex-spouse benefit Up to 50% of ex’s FRA benefit Marriage lasted 10+ years; divorced 2+ years; not remarried
Survivor benefit Up to 100% of deceased’s benefit Can claim as early as 60 (reduced) or FRA (full)
When higher earner delays Survivor gets the higher delayed amount This is why the bigger earner should delay to 70 if possible

When to Claim Early (62-64)

Situation Why Early Makes Sense
Serious health issues May not reach the breakeven age
No other income and need the money Financial survival takes priority
Spouse has a larger benefit and is delaying One claims early while the higher earner maximizes
Very low benefit amount The difference between 70% and 100% of a small benefit may not matter much

When to Delay (To 70)

Situation Why Delaying Pays Off
Good health and family longevity More years to collect the higher amount
Other retirement income available Can cover expenses without Social Security
You’re the higher earner in a couple Maximizes survivor benefit for your spouse
Still working and earning above the limit Benefits would be withheld anyway
Want the guaranteed 8%/year increase No other investment offers a guaranteed 8% return

The Bottom Line

Social Security is the only guaranteed lifetime income most retirees have, and the claiming decision is permanent. Before you file, check your earnings record at ssa.gov, model at least 3 claiming ages, factor in spousal and survivor benefits, and understand how working income and taxes affect your benefit. For most healthy people — especially the higher earner in a couple — delaying to 70 is the best financial decision you can make.
