How claiming age changes Social Security
By Jude Wallis
Social Security's primary insurance amount is the benefit at full retirement age. Claiming earlier multiplies PIA by a reduction factor. Claiming later multiplies it by a delayed-retirement factor. On a teaching PIA of $2,345.80, a 0.70 factor pays $1,642.06. A 1.24 factor pays $2,908.79.

A nominal annual rate, divided by twelve here. A compound annual return already has the monthly compounding inside it, so it goes in a little lower than the headline figure.
Flat in cash terms. Raising it each year for inflation empties the pot sooner.

In short
- Claiming age is a multiplier on PIA, not a new AIME calculation.
- A teaching PIA of $2,345.80 times 0.70 is $1,642.06.
- The same PIA times 1.24 is $2,908.79.
- The 0.70 and 1.24 factors on this sheet are teaching inputs. Live reduction and delay factors depend on months from full retirement age.
PIA first, then a claiming factor
Primary insurance amount is the monthly benefit at full retirement age, computed from AIME and bend points on how Social Security benefits work. Claiming earlier or later does not recompute AIME. It multiplies PIA:
On a teaching PIA of $2,345.80, a factor of 0.70 produces $1,642.06. A factor of 1.24 produces $2,908.79.
Those factors are inputs on this sheet. The live reduction is a percent per month before full retirement age, with a different percent for the first 36 months than for earlier months. Delayed retirement credits accrue monthly up to a cap. Look up the factor that matches the claiming month.
A smaller monthly check, more months of checks
The 0.70 line is a smaller monthly amount. It also starts earlier, so more months are paid if the claimant is alive. The 1.24 line is a larger monthly amount that starts later. Which total is larger depends on how long the claimant lives, and on spousal and survivor rules this page does not price.
The retirement withdrawal calculator on this page is a portfolio spending rate. Social Security is a statutory annuity. They sit next to each other in a plan. They are not the same identity.
How required minimum distributions work is a different statutory withdrawal, from an account.
Spousal benefits are a different percent
A spousal benefit is often described as up to half of the other spouse's PIA, with its own reduction if claimed early. That is not the 0.70 or 1.24 on this sheet. Those two factors scale the worker's own PIA.
How FICA works is the payroll tax that funded the worker's record. Tax-deferred accounts are a separate income stream in retirement.
Scope of this sheet
The two teaching rows are $2,345.80 times 0.70 ($1,642.06) and times 1.24 ($2,908.79). They are not a full retirement age lookup, not a month-by-month reduction table, and not a break-even age. This is educational material, not financial advice.
Worked examples
PIA times 0.70
PIA is $2,345.80. The teaching early-claiming factor is 0.70. What is the monthly benefit?
- Multiply: .
- The benefit is $1,642.06.
The early-claiming benefit is $1,642.06 on a PIA of $2,345.80 at a factor of 0.70.
PIA times 1.24
PIA is still $2,345.80. The teaching delayed-claiming factor is 1.24. What is the monthly benefit?
- Multiply: , which is $2,908.79 after ordinary rounding to the cent.
- The benefit is $2,908.79.
The delayed-claiming benefit is $2,908.79 on a PIA of $2,345.80 at a factor of 1.24.
Common questions
Is 0.70 the reduction for claiming at 62?
It is a teaching factor on this sheet. The live reduction depends on months from full retirement age, which itself depends on birth year. Look up the factor that matches the claiming month.
Does delaying always raise lifetime benefits?
It raises the monthly amount, up to the delayed-retirement cap. Lifetime totals depend on longevity, spousal benefits, and other income. This page prices one month's benefit, not a lifetime total.
