How to use this calculator
- 1
Find your AIME (Average Indexed Monthly Earnings) on your Social Security Statement at ssa.gov — or estimate it by dividing your average annual earnings by 12.
- 2
Select your birth year — this determines your Full Retirement Age (FRA), which is 66 for those born 1943–1954 and 67 for those born 1960 or later.
- 3
Enter your claiming age — you can claim as early as 62 (reduced benefit) or delay up to 70 (maximum benefit).
- 4
Delaying beyond FRA earns 8% per year in delayed retirement credits.
Frequently asked questions
What is the break-even age for delaying Social Security?
If you delay from 62 to 67 (FRA), your monthly benefit increases ~30%. The break-even point where total lifetime benefits equal each other is roughly age 78–80. If you expect to live past 80, delaying is typically better; if health concerns suggest a shorter lifespan, claiming early may be better. Consider other factors: spouse benefits, taxes, and cash flow needs.
How much of Social Security is taxable?
If your "combined income" (AGI + non-taxable interest + 50% of SS benefits) is under $25,000 (single) or $32,000 (MFJ), your benefits are not taxed. Up to 50% is taxable between $25K–$34K (single). Up to 85% is taxable above $34,000 (single) or $44,000 (MFJ). At least 12 states also tax Social Security benefits.
Can I work while collecting Social Security before FRA?
Yes, but there's an earnings test before FRA. In 2024, if you claim before FRA, $1 in benefits is withheld for every $2 you earn above $22,320. In the year you reach FRA, $1 is withheld for every $3 above $59,520 (for months before your FRA birthday). After FRA, you can earn unlimited income without any reduction.
What are spousal and survivor benefits?
A spouse can claim up to 50% of the other spouse's PIA (at FRA). A surviving spouse can receive 100% of the deceased's benefit. These can significantly impact the optimal claiming strategy — generally, the lower-earning spouse should claim early and the higher earner should delay to maximize the survivor benefit.

How Social Security benefits are calculated
SSA calculates your Primary Insurance Amount (PIA) using your 35 highest earning years (indexed for inflation). The formula applies three "bend points": 90% on the first $1,174 of AIME, 32% on AIME between $1,174 and $7,078, and 15% on AIME above $7,078. This progressive formula gives lower-wage workers a higher replacement rate than higher-wage workers.
The 8% delayed retirement credit
For every year you delay beyond your Full Retirement Age (up to age 70), your monthly benefit increases by 8%. This is a guaranteed, inflation-adjusted return that no market investment can reliably match. For a married couple where one spouse has a high benefit, delaying to 70 can mean $100,000+ more in lifetime benefits — and a much higher survivor benefit for the lower-earning spouse.
