Social Security Claiming Age Calculator

Deciding when to claim Social Security is one of the biggest retirement decisions you'll make. Claiming at 62 gives you smaller checks for longer; waiting until 70 gives you checks about 77% larger than at 62, for life. This calculator compares your options so you can see the trade-off.

What this calculator does

Enter your monthly benefit at full retirement age (67), the age you plan to claim and the age you want to plan for. It shows:

• your monthly benefit at your claiming age,
• your lifetime benefits in today's dollars,
• the claiming age with the highest lifetime total for the life expectancy you entered, and
• the age when waiting until 70 beats claiming at 62.

The chart shows lifetime benefits at several claiming ages.

The formula in plain English

Your benefit at 67 is your primary insurance amount (PIA).

Claiming early reduces it:

• 5/9 of 1% for each of the first 36 months before 67 (about 6.7% a year), and
• 5/12 of 1% for each month beyond 36 (5% a year).

At 62, that's a 30% reduction, or 70% of your PIA.

Waiting past 67 adds 2/3 of 1% a month (8% a year), up to 124% of your PIA at 70.

Lifetime benefits = monthly benefit × 12 × years from claiming to your planning age.

Break-even: the age at which total benefits from claiming at 70 catch up with claiming at 62. With today's rules, it's a little after 80.

A worked example

Dr. Johnson's statement shows $3,400 a month at 67. She plans for a life expectancy of 88.

• Claim at 62: about $2,380 a month, about $742,600 by 88.
• Claim at 67: $3,400 a month, about $856,800 by 88.
• Claim at 70: about $4,216 a month, about $910,700 by 88.
• Break-even between 62 and 70: about age 80.4.

If she lives past about 80, waiting until 70 pays more. Because she's healthy and married, and her husband would receive her larger benefit if she dies first, waiting looks attractive. But if she needed income at 62 or had serious health concerns, claiming earlier could make sense.

Why it matters at each career stage

If you're: Employed

Many healthcare professionals have high earnings records and good health, which often favors waiting. Your savings can cover the years between retirement and 70, letting Social Security grow.

If you're: Practice owner

Business owners who pay themselves through an S corporation should know that only salary, not distributions, counts toward Social Security. A very low salary lowers future benefits.

Things to consider

Health and family history. If you expect a shorter life, claiming earlier may make sense.

Marriage. Survivor benefits make the higher earner's claiming age especially important.

Other income. If you have enough savings to wait, delaying is like buying an inflation-adjusted annuity at a good price.

Taxes. Up to 85% of benefits can be taxable, depending on your other income.

Still working. Before full retirement age, the earnings test may reduce checks if you're still earning.

Social Security in your retirement plan

Social Security is guaranteed for life and rises with inflation each year, which makes it valuable insurance against outliving your savings. Even a few hundred dollars more a month from waiting can make a big difference in your 80s and 90s.
