Social Security Claiming Age & Break-Even Calculator

How this calculator works

You can start Social Security retirement benefits at any age from 62 to 70. Claiming early gives you smaller checks for more years; waiting gives you larger checks for fewer years. This calculator compares two claiming ages side by side and finds the break-even age, the point at which the later claim has paid out the same total as the earlier one.

The inputs. Enter your Primary Insurance Amount (PIA), which is your monthly benefit at full retirement age (FRA). It appears on your Social Security Statement, or you can estimate it with our benefit calculator. Add your birth year so the tool can set your FRA, pick two claiming ages to compare, and optionally enter a yearly COLA assumption.

The formula.

1. FRA is 67 for anyone born in 1960 or later, and between 66 and 66 and 10 months for those born 1955 to 1959.
2. For each claiming age, the monthly benefit is PIA reduced by 5/9 of 1% per month for the first 36 months before FRA and 5/12 of 1% per month beyond that, or increased by 2/3 of 1% per month after FRA, up to age 70.
3. The tool adds up the payments received from each start age through each later birthday to give cumulative totals.
4. The break-even age is the first point where the later claim's running total equals or passes the earlier claim's total.

If you enter a COLA assumption, both benefit streams are raised by the same percentage each year. Because COLAs are a percentage, they add more dollars to the larger, later benefit, which tends to move the break-even age slightly earlier.

Worked example. Carol was born in 1964, so her FRA is 67. Her PIA is $2,000. She compares claiming at 62 with claiming at 70, with no COLA assumption.

• At 62: 60 months early, so 70% of PIA = $1,400 a month.
• At 70: 36 months of delayed credits, so 124% of PIA = $2,480 a month.

The break-even point comes where $1,400 × months since 62 equals $2,480 × months since 70. Solving gives about 80 years and 4 months. If Carol lives beyond that, waiting until 70 pays more in total; if not, claiming at 62 does. By 90 the gap is $124,800 in favor of waiting. Our break-even guide walks through the reasoning in more detail.

Limits of this estimate. The break-even age is a useful reference, not a recommendation. It ignores income taxes, investment returns on money you do not spend, the earnings test if you work before FRA, and the effect of your choice on a surviving spouse, who may inherit the larger benefit. Health, family history, other savings and whether you need the income now all matter. Married couples should also look at the survivor benefit calculator, since the higher earner's claiming age sets the survivor's benefit.
