Social Security Estimator
Estimate your monthly Social Security benefit from average indexed earnings.
How to use the Social Security Estimator
The Social Security Estimator is free and runs entirely in your browser — no sign-up, and nothing you enter leaves your device. It opens pre-filled with a realistic example, so you can see how it works before replacing any figure with your own; the results update as you type. Press Calculate to refresh the result panel, or Reset to return to the example.
The inputs it asks for:
- Average Indexed Monthly Earnings (AIME) — a dollar amount.
- Claiming Age — choose one — 62 (Early), 67 (Full Retirement Age), 70 (Delayed).
The formula
Social Security replaces a progressively smaller share of higher earnings. It runs your average indexed monthly earnings through the benefit "bend points" to get your full-retirement-age benefit (PIA), then adjusts for when you claim:
PIA = 90%·(first $1,174) + 32%·(next tier to $7,078) + 15%·(rest)
- AIME
- your average indexed monthly earnings
- bend points
- the 2024 thresholds ($1,174 and $7,078) where the replacement rate steps down
- claim adjustment
- 62 ≈ 70% of PIA, 67 (FRA) = 100%, 70 ≈ 124%
A simplified estimate using one year's bend points and three claiming ages; your real benefit depends on your full 35-year indexed earnings history and your exact full-retirement age. Treat it as a ballpark, not your official figure.
Worked example
Using the example values — Average Indexed Monthly Earnings (AIME) $6,000.00, Claiming Age 67 (Full Retirement Age) — the Social Security Estimator returns a Estimated Monthly Benefit of $2,600.92. It also reports Primary Insurance Amount (FRA) ($2,600.92), Claiming Age (67), Annual Benefit ($31,211.04).

- PIA (Primary Insurance Amount)
- The monthly benefit at full retirement age.
- Bend points

Frequently asked questions
Why do the percentages fall as earnings rise?
By design — Social Security replaces more of a low earner's income than a high earner's. The 90/32/15% bend points make it progressive.
How much does claiming age matter?
A lot. Claiming at 62 permanently cuts the benefit to about 70% of PIA; waiting to 70 raises it to about 124%. The trade-off is fewer years of a larger check.
Is this my official benefit?
No — it's a simplified estimate. Your real figure comes from your Social Security statement, based on your complete earnings record.
