Social Security Delay: Why Waiting Until 70 is Your Best Investment (8% Guaranteed)

โœ๏ธ By Team BMT (CPA) | ๐Ÿ“… Updated: Dec 16, 2025 | โš–๏ธ Authority: Social Security Act (Delayed Retirement Credits) / SSA.gov

EXECUTIVE SUMMARY

  • The Mechanism: For every year you delay taking Social Security past your Full Retirement Age (FRA, usually 67), the government increases your benefit by 8% per year (simple interest) until age 70. This is called the “Delayed Retirement Credit.
  • Authority Baseline: This analysis follows the benefit calculation rules established by the Social Security Administration, which confirm that claiming at 70 results in a monthly check 76% higher than claiming at 62.
  • Scope Limitation: This strategy applies to healthy individuals expecting to live past age 80. If you have a terminal illness or short life expectancy, claiming early (62) is mathematically superior.
  • Anti-Exaggeration: The 8% is not an investment return you can withdraw; it is an increase in an annuity payment. It dies when you die (unless your spouse inherits it).

Investing in the S&P 500 is risky. Buying an annuity is expensive. But delaying Social Security is risk-free, inflation-protected, and tax-efficient. Where else can you buy a government-guaranteed bond paying 8% real yield? According to Team BMT Analysis, delaying Social Security is the single most efficient way to buy “Longevity Insurance.

Strategic Mechanics: The “Bridge” Strategy

Scenario: You retire at 62. Benefit at 62 is $1,500. Benefit at 70 is $2,640.

  • The Trap: Taking $1,500 at 62 because “I need income now.”
  • The Bridge: Instead of taking Social Security, withdraw $1,500/month from your 401(k) from age 62 to 70.
    Logic: You are spending your 401(k) (which has market risk) to buy a larger Social Security check (which has no risk).
  • Result: At 70, you stop 401(k) withdrawals and turn on the $2,640 Social Security. You have significantly de-risked your late retirement.

Benefit Comparison: 62 vs. 67 vs. 70

Claiming Age Monthly Benefit (% of FRA)
Age 62 (Early) 70
Age 67 (Full / FRA) 100
Age 70 (Delayed) 124

*Chart Note: The jump from 62 to 70 is a 76% permanent raise. In a world of 4% interest rates, locking in an 8% annual increase is an arbitrage opportunity.

CRITICAL SCENARIO: The “Survivor Benefit” Factor

Protecting the lower-earning spouse.

Situation Higher Earner’s Decision Impact on Survivor
Claims Early (62) Gets smaller check. Dies at 75. Spouse inherits the SMALL check forever. (Poverty risk).
Claims Late (70) Gets max check. Dies at 75. Spouse inherits the MAX check forever. (Security).
Fail Condition: This strategy fails if the higher earner claims early purely for personal gratification, ignoring that their decision dictates the survivor’s income for potentially 20+ years after their death.

Execution Protocol

1
Calculate “Breakeven” (Wrong Way)
Most people calculate the “Breakeven Age” (usually ~80) and say “I might die before 80, so I’ll take it now.” This is wrong. You don’t insure for the average outcome; you insure for the tail risk (living to 95).
Decision Order: Assess Health/Longevity โ†’ Consider Spouse’s Needs โ†’ Check Liquidity for Bridge Period.
2
Build the Bridge
Designate a portion of your IRA/401(k) to fund your lifestyle from age 62 to 70. This creates the “income” you need while waiting.
Tax Bonus: Spending Pre-Tax 401(k) money in your 60s reduces your future RMDs (Required Minimum Distributions) at age 73. See RMD Death Spiral (#380).
3
File at 70
You must proactively file. It doesn’t start automatically. If you forget, they will pay you up to 6 months of retroactive benefits, but you lose the delay credits for those months.
Fail Condition: Waiting past 70. There is zero benefit to delaying past age 70. Credits stop accumulating.

WEALTH STRATEGY DIRECTIVE

  • Do This: If you are the higher earner in a married couple, delay until 70. This maximizes the survivor benefit, which is the cheapest life insurance you can buy.
  • Avoid This: The “Bird in the Hand” fallacy. Taking $1 now vs. $2 later is only smart if you are starving. If you have savings, buy the $2.

Frequently Asked Questions

What if Social Security goes bankrupt?

Even in the worst-case scenario (Trust Fund depletion in 2033), tax revenue covers ~80% of benefits. A 20% cut to a “Max Check” at 70 is still larger than a 20% cut to a “Min Check” at 62.

Can I suspend benefits?

Yes. If you claimed at 62 and regret it, once you reach FRA (67), you can “Suspend” benefits to earn delayed credits until 70. It allows a do-over.

Does working affect benefits?

If you claim early (62-67) and keep working, the “Earnings Test” may withhold your benefits ($1 for every $2 earned above ~$22k). Delaying avoids this penalty entirely.

Disclaimer: Social Security rules are subject to change by Congress. The “Breakeven Age” depends on inflation (COLA) and investment returns. If you have poor health or a family history of short lifespans, delaying benefits may result in less total lifetime income.
