How It Works
This calculator estimates your Social Security retirement benefits using a simplified version of the AIME (Average Indexed Monthly Earnings) formula and shows the impact of projected trust fund depletion.
The basic rule:
- Average Indexed Monthly Earnings (AIME) is calculated from your highest 35 years of earnings, adjusted for wage growth
- The Primary Insurance Amount (PIA) applies a progressive formula: 90% of first $1,174 + 32% up to $7,078 + 15% above that (2026 bend points)
- Early retirement at 62 reduces benefits by ~30%; delayed retirement to 70 increases benefits by ~24% above full retirement age
- The Social Security trust fund is projected to be depleted around 2034, triggering an automatic ~23% benefit reduction under current law
Congress may act to prevent or reduce the projected cuts through tax increases, benefit adjustments, or a combination. These estimates assume current law and projected depletion timelines from the Social Security Trustees' Report.
Tips & Considerations
- Double-check your current age before calculating — even small input errors can significantly change your results.
- Run the calculator with different values to compare scenarios and find the optimal approach for your situation.
- Pay attention to both monthly benefit and monthly benefit — they work together to give you the full picture.
- Bookmark this page for quick access next time you need to manage your finances.
- If you're unsure about your years worked, start with a conservative estimate and adjust from there.
Frequently Asked Questions
Will Social Security really be cut by 23% in 2034?
Under current law, if the trust fund is depleted, benefits would automatically be reduced to match incoming payroll tax revenue — currently projected at about 77% of scheduled benefits (a 23% cut). However, Congress has strong political incentive to act before this happens, as it would affect over 67 million Americans.
How is my Social Security benefit calculated?
SSA takes your highest 35 years of earnings, indexes them for inflation, and calculates your Average Indexed Monthly Earnings (AIME). A progressive formula then converts AIME to your Primary Insurance Amount (PIA). Lower earners replace a higher percentage of pre-retirement income.
Should I claim Social Security at 62 or wait until 70?
Claiming at 62 gives you 8 more years of payments but at a permanently reduced rate (~30% less). Waiting until 70 gives you the maximum benefit (~24% more than age 67). The break-even point is typically around age 80 — if you expect to live past 80, waiting usually pays more total.
Does this calculator account for inflation?
The estimates are in today's dollars. Actual Social Security benefits are adjusted annually for inflation via the Cost of Living Adjustment (COLA). The relative purchasing power of your benefit should remain roughly similar, though many retirees report COLA doesn't fully keep pace with their actual expenses.
What can Congress do to fix Social Security?
Common proposals include raising the payroll tax cap (currently $168,600 in 2025), increasing the payroll tax rate, raising the full retirement age, means-testing benefits for high earners, or changing the COLA formula. Most experts believe a combination of approaches will be needed.
How much have I paid into Social Security?
Employees pay 6.2% of wages up to the cap ($168,600 in 2025), matched by employers for a total of 12.4%. If you've earned $65,000/year for 20 years, you and your employer have contributed roughly $161,000 total. You can check your actual record at ssa.gov.
