How is Social Security calculated?

Social Security retirement benefits are calculated using a three-step formula: (1) Compute your Average Indexed Monthly Earnings (AIME) from your highest 35 years of earnings. (2) Apply the 2024 bend-point formula: 90% of the first $1,174, plus 32% of AIME between $1,174 and $7,078, plus 15% of AIME above $7,078. This gives your Primary Insurance Amount (PIA). (3) Adjust for your retirement age — claiming at 62 reduces your benefit by up to 25–30%; delaying to 70 increases it by 24% vs claiming at 67.

What is the full retirement age (FRA) for Social Security?

Full retirement age (FRA) for Social Security is 67 for anyone born in 1960 or later. For those born 1943–1954, FRA was 66. For 1955–1959 births, FRA is between 66 and 67 (graduating by 2 months per year). You can claim as early as age 62 (with reduced benefits) or as late as 70 (with maximum delayed credits).

How much does Social Security increase for each year you delay?

Delayed retirement credits increase your Social Security benefit by 8% for each year you delay past your full retirement age (67 for those born 1960+). Delaying from age 67 to age 70 (3 years) increases your monthly benefit by 24%. For early claiming before FRA: benefits are reduced by 5/9 of 1% per month for the first 36 months early (roughly 6.67%/year), and 5/12 of 1% per month for earlier months.

What is the maximum Social Security benefit in 2025?

The maximum Social Security retirement benefit for someone claiming at age 70 in 2025 is approximately $5,108 per month ($61,296/year). At full retirement age (67), the maximum is approximately $4,018/month. At age 62 (earliest), the maximum is approximately $2,831/month. These maximums apply to high earners who paid Social Security taxes on the maximum taxable amount ($168,600 in 2024) for 35+ years.

How does UK State Pension compare to US Social Security?

The UK New State Pension (2024/25) pays up to £221.20 per week (~£11,502/year, ~$14,300 USD) at State Pension age 66, rising to 67 by 2028. It requires 35 qualifying National Insurance (NI) years for full pension, 10 years for any pension at all. Unlike the US, the UK State Pension is flat-rate — it does not depend on how much you earned. US Social Security is earnings-based and can be much higher for high earners.

Does Social Security run out of money?

The Social Security Trust Fund is projected by the SSA's 2024 Trustees Report to be depleted by approximately 2035, at which point incoming payroll taxes would cover about 83% of scheduled benefits. This would mean an automatic benefit cut of ~17% unless Congress acts. Social Security has never missed a payment and various reform options exist (raise retirement age, increase taxable earnings cap, adjust benefits for high earners, increase payroll tax rate).

Can non-US citizens receive Social Security?

Non-US citizens can receive Social Security benefits if they: (1) have earned the required 40 work credits (10 years of covered employment), (2) are lawfully present in the US. The US has Totalization Agreements with 30+ countries (including the UK, Canada, Germany, Australia, Japan, France) that allow workers to combine work credits from both countries to qualify. Non-resident aliens may have benefits withheld at a 25.5% flat rate unless a tax treaty applies.

How does Canada's CPP compare to US Social Security?

Canada's Canada Pension Plan (CPP) maximum retirement pension in 2025 is approximately CAD $1,433/month ($1,060 USD) at age 65. CPP requires contributions throughout working years (5.95% employee + 5.95% employer in 2024). The standard age is 65, but you can take it at 60 (reduced 7.2%/year early) or delay to 70 (increased 8.4%/year). CPP is portable across all Canadian provinces and is actuarially sound, funded by a dedicated investment board (CPPIB).

How Social Security Benefits Are Calculated

The Social Security Administration (SSA) uses a progressive bend-point formula that replaces a higher percentage of income for lower earners:

Gather earnings history: SSA takes your highest 35 years of earnings, adjusted for wage inflation. Zeros are included for years without earnings.
Calculate AIME: Average Indexed Monthly Earnings = sum of highest 35 indexed years / 420 months.
Apply 2024 bend points: 90% of first $1,174 + 32% of $1,174–$7,078 + 15% above $7,078 = your Primary Insurance Amount (PIA).
Adjust for claiming age: Claiming before 67 = reduction. After 67 = delayed retirement credits (8%/year).
Add COLA: Cost of Living Adjustments (COLA) — 3.2% in 2024, 2.5% in 2025 — are applied each January.

Early vs Late Claiming: The Break-Even Analysis

Whether to claim early or late depends on your life expectancy and financial needs:

Claim at 62: Lower monthly check, but payments start sooner. Better if you have health concerns or need income immediately.
Claim at 67 (FRA): Full benefit with no reduction. Good baseline for most people.
Claim at 70: 24% more per month than at 67. Break-even vs claiming at 67 is approximately age 82–83. If you expect to live past 83, delaying pays off.
Married couples: The higher earner often benefits from delaying to 70, because the survivor receives the higher of the two benefits.

UK State Pension vs US Social Security: Key Differences

The UK New State Pension (introduced 2016) is a flat-rate system — everyone who qualifies gets the same amount (up to £221.20/week in 2024/25), regardless of how much they earned. This contrasts sharply with the US earnings-based system where high earners receive much more.

UK eligibility: You need 35 qualifying National Insurance (NI) years for the full pension; 10 years for any pension at all. NI years can be earned through employment, self-employment, or NI credits (e.g. for childcare). The UK State Pension age is 66, rising to 67 by 2028.

Canadian CPP: How It Compares

The Canada Pension Plan (CPP) is an earnings-based system like the US, but with some key differences: Canadian workers and employers each contribute 5.95% of earnings in 2024 (up from 4.95% a decade ago, following CPP Enhancement). The standard claiming age is 65, with reductions if taken at 60–64 and increases if delayed to 70. CPP2 (enhanced contributions since 2019) adds additional benefits for higher earners.

Australian Age Pension: Means-Tested

Unlike the US (contributions-based) and UK (NI-based), Australia's Age Pension is means-tested — it depends on your income and assets, not your work history. Most Australians also accumulate mandatory superannuation (Super) through employer contributions (11% of salary in 2023-24, rising to 12% by 2025) which is the primary retirement income source. The Age Pension acts as a safety net for those with insufficient Super.

Frequently Asked Questions

Will Social Security still exist when I retire? ▾

Social Security has never missed a payment in its 89-year history. The 2024 Trustees Report projects the trust fund will be depleted by 2035 if no changes are made, at which point incoming payroll taxes would cover ~83% of scheduled benefits — a ~17% automatic cut. Congress has historically acted before trust fund depletion. Options include: raising payroll tax rates, increasing the taxable earnings cap (currently $168,600), raising the retirement age, or means-testing benefits for high-income retirees.

What counts toward my Social Security credits? ▾

In 2024, you earn one Social Security credit for every $1,730 of covered earnings, up to 4 credits per year. You need 40 credits (10 years of work) to qualify for retirement benefits. Credits are also used for disability (SSDI) and survivor benefits. Self-employment income counts, but you must pay self-employment tax (15.3%). Household workers, agricultural workers, and some government employees have different rules.

Can I work while receiving Social Security? ▾

Yes, but with limits if you are below your Full Retirement Age (67). Before FRA: If you earn more than $22,320 in 2024, SSA withholds $1 of benefits for every $2 above the limit. In the year you reach FRA: withholding threshold rises to $59,520 ($1 withheld per $3 above). At FRA and older: No earnings limit — you can earn any amount and receive full benefits. Withheld benefits are not lost — your monthly benefit is recalculated upward at FRA to account for months when benefits were withheld.

How does Social Security work for married couples and divorced spouses? ▾

Married spouses can claim up to 50% of the higher earner's PIA at their own FRA, whichever is greater (their own benefit or the spousal benefit). Divorced spouses can also claim a spousal benefit if the marriage lasted at least 10 years, the ex-spouse is eligible for Social Security, and the divorced spouse is not currently married. Survivor benefits: a surviving spouse can claim up to 100% of the deceased's benefit at their own FRA (or 71.5% at 60). These rules can significantly increase retirement income for single-earner and survivor households.
