SS factor at age 70
By Jude Wallis
Claiming at age 70 is 36 months delayed relative to a teaching full retirement age of 67. The factor is 1.24, so a PIA of 1,000 becomes 1240 a month.
The formula
Multiply PIA by this age's factor. Full retirement age on this sheet is 67.
| Months from FRA | Factor |
|---|---|
| 36 | 1.2400 |
Worked example
What claiming factor applies at age 70 if full retirement age is 67?
- Age 70 is 36 months from 67.
- Read the row for 36 months, giving 1.24.
The factor is 1.24. A 1,000 PIA becomes 1240.
How these figures were checked
Every factor on this page is recomputed before the site can build, by a separate program that works a different way: repeated multiplication instead of a power function, a period-by-period sum instead of a closed-form annuity factor, and a solved loan schedule instead of a payment formula. If the two methods disagree anywhere, the page does not ship. Printed factor tables carry typos because nobody can check three thousand numbers by hand; this one is checked on every build.
