Social Security Estimator Calculator

See monthly benefits using bend points and timing. Model early or delayed filing with details. Download tables, share scenarios, and decide with clarity now.

This tool is an estimator. Bend points and rules can change by program year, so key parameters are editable for scenario planning.

Example Data Table

This sample shows how changing the claiming age can shift monthly benefits.

Scenario Total Indexed Earnings FRA Claim Age Bend Points Estimated Monthly
Baseline $1,400,000 67y 0m 67y 0m $1,200 / $7,200 Varies by adjustment
Early claim $1,400,000 67y 0m 62y 0m $1,200 / $7,200 Lower than baseline
Delayed claim $1,400,000 67y 0m 70y 0m $1,200 / $7,200 Higher than baseline
Replace bend points with your preferred year or policy scenario.

Formula Used

  • AIME: AIME ≈ Total Indexed Earnings ÷ 420 months (35 years × 12). You can also enter AIME directly.
  • PIA at FRA: PIA = 90% × min(AIME, BP1) + 32% × min(max(AIME−BP1, 0), BP2−BP1) + 15% × max(AIME−BP2, 0).
  • Claiming adjustment: Early reduction uses 5/9 of 1% per month for the first 36 months early, then 5/12 of 1% per additional month. Delayed credits use 2/3 of 1% per month delayed.
  • Lifetime totals: Simple nominal = Annual Benefit × Years Receiving. Present value uses a growing annuity based on COLA and discount rate.

  3. Set your full retirement age and your intended claiming age.
  4. Adjust COLA, benefit years, and discount rate for planning.
  5. Click “Estimate Benefits” to see results above the form.
  6. Download a CSV or PDF for sharing and record-keeping.

Planning assumptions that change outcomes

This estimator connects earnings, bend points, and claiming choices to a monthly benefit view. It is designed for scenario planning, not official benefit determination. Use it to test ranges, document assumptions, and communicate tradeoffs with partners, advisors, or family members. Keep inputs stable when comparing scenarios so differences reflect a single variable.

Turning earnings history into AIME

Average indexed monthly earnings, or AIME, represents a career‑level earnings signal expressed per month. You may enter total indexed earnings for 35 years or provide AIME directly. When using the 35‑year total, the calculator divides by 420 months to estimate AIME, creating a consistent baseline. If your career has gaps or uneven peaks, model alternative totals to bracket outcomes.

How bend points shape your PIA

The primary insurance amount, or PIA, is derived from AIME using two bend points and three replacement tiers. The first tier replaces a large portion of earnings up to the first bend point, the second tier replaces a moderate portion up to the second bend point, and the final tier replaces a smaller portion above it. Because bend points vary by year, editable bend points let you explore different policy periods and sensitivity.

Claiming age adjustments and timing

Full retirement age sets the reference point for adjustments. Claiming early reduces the PIA, using a higher monthly reduction for the first 36 months and a lower rate for additional months. Delaying increases the benefit through monthly credits after full retirement age. Small age changes can meaningfully shift lifetime cash flow, so compare several ages across a realistic benefit horizon.

Present value and documentation for decisions

Monthly amounts are easy to compare, but present value adds discipline when horizons differ. The calculator estimates a present value for a growing annual stream using your COLA assumption and discount rate. Use this view to compare options on a consistent basis, then export CSV for spreadsheet analysis and PDF for sharing. Re‑run scenarios and archive outputs to build a clear decision trail. Also consider taxes, spousal benefits, and work plans as separate factors, then adjust assumptions and rerun to see how conclusions change over time.

FAQs

What is AIME and why does it matter?

AIME is an average monthly measure of your indexed earnings history. It is the core input used to compute the PIA, so higher sustained earnings generally raise the estimated baseline benefit.

Why are bend points editable?

Bend points shift over time and can differ by policy year. Editable bend points let you test sensitivity, replicate a published year’s parameters, and evaluate how changes would affect your estimate.

How does early claiming reduce benefits?

If you claim before full retirement age, the calculator applies a monthly reduction: a higher rate for the first 36 months early, then a slightly lower rate for additional early months.

What does present value represent here?

Present value discounts a future stream of benefits into today’s dollars using your discount rate and growth assumption. It helps compare options with different timing on a consistent basis.

Does the calculator include taxes or spousal rules?

No. It focuses on an individual benefit estimate using simplified inputs. Model taxes, survivor or spousal provisions, and work plans separately, then adjust your scenario assumptions as needed.

Why might my official statement differ from this estimate?

Official calculations use detailed indexing, exact earnings records, program-year parameters, and eligibility rules. This tool simplifies inputs for planning, so treat results as directional and compare against official sources.
