What this calculator does
The Retirement Calculator estimates a future nest egg, monthly retirement income, income gaps, and optional Social Security benefit impact using either an SSA amount you enter or a DynoCalc estimate.
When to use it
Use it when you want to compare savings, claiming ages, bridge years before benefits start, taxable Social Security estimates, or whether Social Security changes the pressure on portfolio withdrawals.
How it works
DynoCalc compounds the current balance, estimates 4% portfolio income, and optionally applies 2026 Social Security rules for AIME, PIA, full retirement age, early reductions, delayed credits, COLA, taxable maximum, and earnings-test thresholds.
Example scenario
Someone retiring at 62 but claiming Social Security at 67 can see five bridge years without benefits, higher portfolio withdrawals during that period, and lower withdrawals after benefits begin.
Common mistakes
- Treating an estimate as an official SSA determination.
- Assuming Social Security starts automatically at retirement age.
- Confusing “up to 85% taxable” with an 85% tax rate.
- Ignoring spouse, survivor, non-covered employment, and working-while-claiming rules.
FAQs
Can DynoCalc estimate Social Security without connecting to SSA?+
Yes. You can enter your own SSA estimate or let DynoCalc make an educational estimate from covered earnings. DynoCalc does not connect to SSA and does not need your Social Security number.
How is Social Security calculated?+
The estimate uses AIME, PIA bend points, full retirement age, early claiming reductions, delayed credits, and the selected claiming age.
What is AIME?+
AIME means Average Indexed Monthly Earnings. Social Security uses the highest 35 years of covered earnings after indexing.
What is PIA?+
PIA means Primary Insurance Amount. It is the base monthly benefit before claiming-age adjustments.
Should I claim at 62, full retirement age, or 70?+
DynoCalc compares estimated benefits and retirement cash-flow impact, but it does not tell you what to do. Verify benefits with SSA and consult qualified financial and tax professionals.
Can I enter my own SSA estimate?+
Yes. Choose Enter my SSA amount and enter the monthly benefit, estimate age, claiming age, and whether the amount is in today’s or future dollars.
Does DynoCalc need my Social Security number?+
No. Do not enter a Social Security number. DynoCalc does not ask for SSA credentials or connect to your SSA account.
How does Social Security affect retirement withdrawals?+
When Social Security is included, DynoCalc adds the benefit after the selected claiming age and reduces the income gap that would otherwise need to come from portfolio withdrawals.
Are Social Security benefits taxable?+
They can be. DynoCalc estimates the taxable portion using provisional income, but this is not tax advice.
