Your Social Security Benefit at Age 70: Key Factors
Your monthly Social Security benefit at age 70 isn't a single, fixed amount for everyone. It's the culmination of your lifetime work history and your strategic decision to delay receiving benefits. The final amount is significantly higher than what you would have received at your full retirement age (FRA) or the earliest claiming age of 62.
The most important factor is the delayed retirement credits (DRCs) you accumulate. For anyone born in 1943 or later, the benefit increases by 8% for each year you wait past your FRA, up until age 70. Since the FRA for those born in 1960 or later is 67, waiting until 70 results in a substantial 24% increase.
How Your Benefit is Calculated
To understand your benefit, it’s helpful to know the calculation process used by the Social Security Administration (SSA). The two primary steps are:
- Average Indexed Monthly Earnings (AIME): The SSA takes your 35 highest-earning years and indexes them to account for changes in average wages over time. This creates your AIME. If you worked fewer than 35 years, years with no earnings are counted as zeros, lowering your average. For many people, working up to age 70 allows them to replace some of their lower-earning years from earlier in their career with higher-earning ones, further boosting their benefit.
- Primary Insurance Amount (PIA): A weighted formula is applied to your AIME to determine your PIA, which is the amount you would receive at your FRA. This formula is progressive, meaning it replaces a higher percentage of earnings for lower-income workers.
Average vs. Maximum Benefit at Age 70
It’s important to distinguish between the average benefit, which represents what most people receive, and the maximum, which is reserved for the highest earners.
- Average Benefit: For a 70-year-old in 2025 who had average earnings and delayed claiming, the estimated average monthly benefit is around $3,107.78. This figure is a national average and can vary widely based on individual circumstances.
- Maximum Benefit: For 2025, the maximum possible benefit for someone retiring at age 70 is $5,108 per month. To achieve this, an individual must have earned the maximum taxable amount of income for at least 35 years and delayed claiming until age 70.
Should You Keep Working After Age 70?
If you reach age 70 and are still employed, you can continue to work without a penalty, and there's no limit on your earnings. Any earnings you have after age 70 may actually increase your benefit if your current income replaces one of the 35 highest-earning years used in the original calculation. However, DRCs stop accumulating at age 70, so there's no additional benefit to delaying claiming past this age.
The Impact of Taxes on Your Benefits
When planning your retirement income, remember that your Social Security benefits may be taxable. The taxability depends on your combined income, which includes your adjusted gross income, tax-exempt interest income, and one-half of your Social Security benefits. Up to 85% of your benefits can be subject to federal income tax if your income exceeds certain thresholds.
A Comparison of Claiming Ages
Consider how your monthly benefit changes depending on when you choose to start receiving payments. Here's a table comparing benefits for someone with a Full Retirement Age (FRA) of 67, based on the percentage of their PIA they would receive:
| Claiming Age | Benefit Percentage | Impact on Monthly Income |
|---|---|---|
| 62 | 70% | Permanently reduced benefit for claiming early |
| 67 (FRA) | 100% | Full benefit amount, with no reduction or increase |
| 70 | 124% | Maximum possible benefit through DRCs; 24% higher than at FRA |
Conclusion
Deciding when to claim Social Security is one of the most critical financial decisions you'll make for your retirement. While the earliest age is 62, waiting until age 70 can result in a significantly larger monthly benefit for the rest of your life. This can be a vital hedge against inflation and other rising costs in your later years. Factors like your health, life expectancy, and other retirement savings should influence your choice.
