A Primary Insurance Amount (PIA) is the monthly Social Security retirement benefit payable at full retirement age (FRA), before adjustments for claiming early or late. This calculator estimates PIA from your Average Indexed Monthly Earnings (AIME), then estimates monthly benefits at 62, FRA, and 70.
With the default inputs—$5,000 AIME and birth year 1965—the calculator estimates a $2,280.92 monthly PIA, $27,371 annual benefit at FRA, $1,597 per month at 62, and $2,828 per month at 70. It sets FRA to 67 for this birth year.
The estimate is only as accurate as the AIME and bend points entered in the model. Social Security calculates AIME from a worker’s covered earnings history, generally using the highest 35 years after wage indexing. If you need to estimate that earnings figure first, use the Social Security AIME Calculator. For an official personalized estimate, check your earnings record and benefit estimate through my Social Security.
Enter AIME and Birth Year
Enter your estimated AIME, birth year, current age, and planned retirement age. In this calculator’s computation, AIME and birth year determine the results; current age and planned retirement age are not used in the benefit formula. Use the result cards to compare monthly PIA, annual FRA benefits, and the model’s age-62 and age-70 estimates.
The calculator applies three progressive tiers to AIME: 90% of the first $1,174, 32% from $1,174 to $7,078, and 15% above $7,078. These are the bend points coded into this calculator. Social Security bend points change by eligibility year, so the estimate should not be mistaken for an official 2026 award calculation. The SSA explains the official benefit formula and bend points.
For the default $5,000 AIME, the first tier contributes $1,174 × 90% = $1,056.60. The second contributes ($5,000 − $1,174) × 32% = $1,224.32. AIME does not exceed $7,078, so the third tier contributes $0. The sum is $1,056.60 + $1,224.32 = $2,280.92.
How Early and Delayed Claiming Change PIA
PIA is a baseline, not necessarily the check you receive. Claiming before FRA reduces the monthly amount; delaying past FRA can increase it, up to age 70 for retirement benefits. For people born in 1960 or later, FRA is 67. The SSA retirement planner explains how early and delayed claiming adjustments work.
This calculator’s age-62 adjustment uses a reduction of 5/9 of 1% for each of the first 36 months before FRA and 5/12 of 1% for each additional month. Its age-70 estimate uses delayed credits of 2/3 of 1% per month after FRA. For the default birth year, claiming at 62 is 60 months early: 36 months at the first reduction rate and 24 at the second. The model’s factor is 1 − (36 × 5/900) − (24 × 5/1200) = 0.70. Thus, $2,280.92 × 0.70 = $1,596.644, rounded to $1,597.
At age 70, the modeled delayed-credit factor is 1 + (36 × 2/300) = 1.24. Therefore, $2,280.92 × 1.24 = $2,828.3408, rounded to $2,828. Actual benefits use the applicable rules and may differ because of birth date, claiming month, COLAs, and other adjustments.
| AIME | Estimated PIA | At 62 (modeled) | At 70 (modeled) |
|---|---|---|---|
| $3,000 | $1,640.92 | $1,149 | $2,035 |
| $5,000 | $2,280.92 | $1,597 | $2,828 |
| $7,000 | $2,945.88 | $2,062 | $3,653 |
| $9,000 | $3,522.18 | $2,466 | $4,368 |
The table holds the calculator’s bend points and FRA assumptions constant. It shows the progressive formula: each additional dollar of AIME increases PIA by 90 cents in the first tier, 32 cents in the second, and 15 cents in the third. It does not mean each worker’s actual benefits will match these estimates.
The PIA Formula, Step by Step
The formula splits AIME into portions rather than applying one percentage to all earnings. Each portion receives the percentage assigned to its tier, and the tier amounts are added to find PIA.
First tier =
minimum of AIME or $1,174, multiplied by 90%
Second tier =
AIME between $1,174 and $7,078, multiplied by 32%
Third tier =
AIME above $7,078, multiplied by 15%
PIA = first tier + second tier + third tier
For the default AIME, that becomes $1,056.60 + $1,224.32 + $0 = $2,280.92. Annualizing PIA gives $2,280.92 × 12 = $27,371.04, displayed as $27,371. The benefit at 62 and 70 is calculated by multiplying PIA by the relevant reduction or credit factor, then rounding to a whole dollar.
AIME itself is not the same as salary or your last year’s earnings. It is based on indexed covered earnings, with a 35-year calculation that can include zero years if you have fewer than 35 years of covered earnings. To explore benefit estimates from different earnings histories, use the Social Security Calculator or the Social Security Early Retirement Calculator.
What PIA Does Not Include
This is an individual retirement estimate. It does not calculate a spouse’s benefit, survivor benefits, family maximum, taxes, or the effect of continuing to work. If you have a spouse, compare individual estimates with the Spousal Social Security Calculator and the Social Security Strategy Calculator.
The calculator also does not estimate the taxable portion of Social Security. Federal taxation depends on combined income and filing circumstances; state tax treatment varies. It does not account for the earnings test that may temporarily withhold benefits from some people who claim before FRA and continue working. Use the Social Security Earnings While Working Calculator for that question.
The estimate can still be useful as a retirement income input. Add it to pensions, savings, and spending in the Retirement Calculator with Pension and Social Security. If you are comparing claim dates, read when to take Social Security: 62 vs. 67 vs. 70.
Next Steps
Verify your earnings record and official benefit estimate, then compare claiming ages using your actual FRA and likely cash-flow needs. Use the Social Security Delayed Retirement Calculator to explore a later claim, and include the result in a full retirement income plan.
Frequently Asked Questions
Quick answers to the questions people usually have after running the retirement calculator.
1Is PIA the same as my Social Security check?
Not always. PIA is the FRA baseline. Early or delayed claiming, cost-of-living adjustments, Medicare premiums, tax withholding, and other factors can change the amount paid.
2Why does the calculator use bend points of $1,174 and $7,078?
Those are the bend points coded into this calculator’s formula. Official bend points depend on the year a person first becomes eligible, so verify the applicable values with the SSA’s PIA formula.
3How do I find my AIME?
Use your covered earnings record and an official benefit estimate, or estimate AIME with the Social Security AIME Calculator. AIME is not simply your current monthly salary.
4Does the calculator’s age-62 amount apply to everyone?
No. It applies a model-specific 70% factor for this birth-year setup. The actual reduction depends on your FRA and exact claiming month. Confirm the amount using your official estimate.
5Should I claim at 62 or wait until 70?
Claiming early provides payments sooner but reduces the monthly amount; delaying can increase the monthly amount but means giving up earlier checks. Compare expected longevity, cash needs, work plans, and household benefits instead of relying on a single monthly figure.
6Why is my annual benefit not exactly 12 times the displayed PIA?
The calculator rounds the annual amount to a whole dollar. The default PIA multiplied by 12 is $27,371.04, which displays as $27,371.
7Does a higher AIME always raise PIA by 90% of the increase?
No. AIME is divided among progressive tiers. Once earnings pass a bend point, the next portion receives a lower percentage in the formula.
