When Should You Claim Social Security?

How Social Security Benefits Are Calculated

Your Social Security benefit is based on your 35 highest-earning years, adjusted for wage inflation. The Social Security Administration calculates your Primary Insurance Amount (PIA) — the benefit you'd receive at your Full Retirement Age (FRA). For most people currently approaching retirement, FRA is 67.

You can claim as early as 62 or as late as 70. The difference is substantial:

On a $2,000 monthly PIA, this means claiming at 62 yields roughly $1,400/month, at 67 yields $2,000/month, and at 70 yields $2,480/month — a 77% difference between the earliest and latest claiming ages.

The Break-Even Analysis

The break-even age is when the cumulative payments from delayed claiming catch up to the cumulative payments from early claiming. Because you collect fewer months of benefits when claiming late, you need to live long enough to come out ahead.

For claiming at 70 vs 62, the break-even age is typically around 80–82. For claiming at 70 vs 67, it's around 80–81. These calculations ignore investment returns on Social Security income — if you invest the early payments, the break-even age shifts higher.

What the Break-Even Analysis Misses

The break-even framework treats Social Security as an investment with a return — but it is more accurately understood as longevity insurance. The value of a higher benefit at 70 is greatest precisely when you need it most: in advanced old age, when your investment portfolio may be depleted and healthcare costs are rising. A higher Social Security benefit at 85 or 90 is more valuable than the same dollar amount at 65.

Key Factors That Affect the Decision

1. Your Health and Life Expectancy

If you have significant health issues or a family history of shorter lifespans, earlier claiming may make mathematical sense. If you are in excellent health and have family members who lived into their late 80s or 90s, delaying to 70 is almost certainly the right financial decision.

2. Your Financial Need

If you retire at 62 and need income to cover expenses, claiming early may be necessary regardless of the optimization math. Conversely, if you have significant retirement savings and can bridge the gap to 70 with portfolio withdrawals, delaying is typically advantageous — especially because you're drawing down assets that will eventually deplete, while building up a permanent guaranteed income stream.

3. The Earnings Test

If you claim before your FRA and continue working, your benefit is temporarily reduced if your earnings exceed $22,320 (2025 threshold). For every $2 you earn above this limit, $1 is withheld from benefits. Once you reach FRA, the earnings test disappears and your benefit is recalculated to credit the withheld months. This is not a permanent loss — but it does complicate early claiming for people who continue working.

Spousal Benefits

Social Security spousal benefits add another dimension to the claiming decision. A spouse can receive up to 50% of their partner's PIA as a spousal benefit — regardless of their own work history. The spousal benefit is not reduced by delaying past FRA (unlike the primary benefit, which grows 8% per year to 70). So a lower-earning spouse generally should claim at FRA, not delay.

Survivor Benefits

The survivor benefit — what a spouse receives after their partner dies — equals 100% of the deceased's benefit (including delayed credits). This makes the higher earner's claiming decision particularly significant in married couples. By delaying to 70, the higher earner permanently increases the survivor benefit that will support the surviving spouse for the rest of their life. For many married couples, this is the single strongest argument for the higher earner to delay to 70 even if the lower earner claims earlier.

The Optimal Strategy for Most Couples

A common optimization for married couples is:

• Lower earner claims at 62 or FRA to generate income during the bridge period.
• Higher earner delays to 70 to maximize their benefit and the future survivor benefit.

This approach is not universal — it depends on age differences, health, and financial resources. But for couples where the higher earner is in good health and has resources to bridge to 70, this combination often produces the best lifetime income outcome.

The Bottom Line

Delaying Social Security to 70 is the right choice for most people who are in good health and have the financial resources to wait. It provides a guaranteed, inflation-adjusted income for life that becomes increasingly valuable in the later years of retirement — when market volatility, healthcare costs, and cognitive decline make managing a large investment portfolio more difficult. If in doubt, delay.
