What is the Social Security breakeven age?

The age at which the total dollars from a larger, later check catch up to the total from a smaller, earlier one. Claim at 62 and you collect for more years; wait until 70 and each check is roughly 77% larger. Most charts put the crossover in the late 70s to early 80s. This calculator shows that number and then recalculates it with federal tax included.

Why does adding taxes change the breakeven?

Because the dollars are not taxed the same way. Money you withdraw from an IRA to cover the gap while you wait is fully taxable. Social Security is at most 85% taxable, and for many retirees far less. When a larger share of your yearly cash flow comes from Social Security, less of it is taxed, so the after-tax breakeven usually arrives earlier than the check-only version.

Should everyone wait until 70 to claim?

No. Health, family longevity, whether you are still working, a spouse's benefit, and how much you hold in pre-tax accounts all matter. The calculator on this page is for seeing the tax side of your own numbers, which most claiming advice skips, so the decision is made with the whole picture.

The Social Security breakeven, with the taxes put back in.

Every breakeven chart you've seen compares the size of the checks and stops. But pretax IRA withdrawals and Social Security are not taxed the same way, so the claiming age also changes your tax bill every single year. Put in your own numbers and see the breakeven computed both ways.

Your numbers

Your full-retirement-age benefit is on your SSA statement (ssa.gov/myaccount). Full retirement age for your year: 67. Model: single filer, 2026 federal rules, today's dollars, a traditional IRA covers whatever the check doesn't.

At age 71, per year	Claimed 62	Claimed FRA	Claimed 70
Social Security received	$16,800	$24,000	$29,760
IRA withdrawal (counts in full)	$33,397	$24,742	$18,240
Provisional income (worksheet input)	$41,797	$36,742	$33,120
Social Security that counts	$11,127	$6,831	$4,060
Income that counts (AGI)	$44,524	$31,573	$22,300
Standard + age-65 deduction	-$18,150	-$18,150	-$18,150
Senior deduction (2025-28)	-$6,000	-$6,000	-$6,000
Taxable income	$20,374	$7,423	$0
Federal tax	$2,197	$742	$0

Only part of Social Security is taxable: none below $25,000 of provisional income (other income plus half your benefit), up to 50% between $25,000 and $34,000, and up to 85% above that, never more than 85%. IRA withdrawals count in full. Tax uses the 2026 single brackets. Check any column by hand, it will foot.

Hover the chart to compare any age. Lower line = more IRA still in your name.

Both lines keep after-tax spending identical every year; whichever line is lower has burned less IRA. Single filer, 2026 federal rules held constant in today's dollars, including the $6,000 senior deduction, which under current law applies for tax years 2025 through 2028 only. No investment growth either direction, and not a recommendation of when to claim: health, survivor benefits for couples, and growth on money left invested all matter too.
