How to calculate your Social Security break-even age

Step 1: Understand the three claiming ages

Social Security lets you start benefits anywhere from age 62 to age 70. Three reference points matter:

• Age 62 — earliest possible claim. Reduced benefit (30% lower than FRA for someone with FRA of 67).
• Full Retirement Age (FRA) — for people born in 1960 or later, FRA is 67. You receive your "full" benefit at this age.
• Age 70 — latest claim. Each year past FRA adds 8% Delayed Retirement Credit, up to 24% above FRA.

Step 2: Get your benefit estimates

Log into ssa.gov and view your statement. SSA provides three estimated monthly benefits: claiming at 62, at FRA, and at 70. Use these exact numbers — don't estimate.

For example purposes, assume:

• Age 62 benefit: $1,400/month
• FRA (67) benefit: $2,000/month
• Age 70 benefit: $2,480/month

Step 3: Compute cumulative benefits at each age

For each claiming option, multiply the monthly benefit by 12 and then by the number of years between the claim age and the test age. This gives lifetime benefits received as of the test age.

Comparing claim-at-62 vs claim-at-67: By age 78, the early claimer has received benefits for 16 years. The FRA claimer has received benefits for 11 years. Compute both totals:

• Early: $1,400 × 12 × 16 = $268,800
• FRA: $2,000 × 12 × 11 = $264,000

At 78, early is still slightly ahead. Move forward one year.

By age 79:

• Early: $1,400 × 12 × 17 = $285,600
• FRA: $2,000 × 12 × 12 = $288,000

At 79, FRA pulls ahead. The break-even is somewhere in age 78-79.

Step 4: Compute the FRA vs age-70 break-even

Same approach.

Comparing claim-at-67 vs claim-at-70:

• Age 80: FRA = $2,000 × 12 × 13 = $312,000; 70 = $2,480 × 12 × 10 = $297,600. FRA still ahead.
• Age 82: FRA = $2,000 × 12 × 15 = $360,000; 70 = $2,480 × 12 × 12 = $357,120. Close.
• Age 83: FRA = $2,000 × 12 × 16 = $384,000; 70 = $2,480 × 12 × 13 = $386,880. Age-70 pulls ahead.

So the FRA-vs-70 break-even is age 82-83 in this example.

Step 5: Layer in survivor benefits

If you're married, the higher-earning spouse's claim age permanently sets the survivor benefit floor for whichever spouse lives longer. Delaying the higher earner's claim from 62 to 70 increases the survivor benefit by 77% — for the rest of the surviving spouse's life. This is often the strongest argument for delaying, separate from break-even math.

Step 6: Layer in taxes

Social Security is up to 85% taxable depending on combined income. Earlier claims pulled into a year with high other income (working part-time, RMDs, Roth conversions) get a higher share taxed. This nuance pushes the break-even calculation slightly toward later claiming for higher-income retirees.

Bottom line

The classic 62-vs-FRA break-even is roughly age 78-79. The FRA-vs-70 break-even is roughly age 82-83. Use SSA's exact benefit numbers from your statement, factor in survivor benefits if you're married, and don't let break-even math be the only input to the decision — longevity insurance and tax planning matter just as much.
