Formulas

  • Nest egg: Annual spending ÷ (Withdrawal rate ÷ 100)
  • 401(k) max $: Elective limit + catch-up (if age ≥ 50)
  • RMD: Balance ÷ Life expectancy factor
  • SSA early: ≈ 5/9 of 1% per month for first 36 months early
  • Annuity PMT: PV × r ÷ (1 − (1+r)^(−n))
  • College FV: PV(1+r)^n + C × ((1+r)^n − 1) ÷ r
  • CD maturity: P × (1 + r/n)^(n×t)
  • HSA total: Salary × employee% + Employer $

Comparison table

Topic Guidance
Nest egg vs annuity PMT Nest egg sizes a portfolio from spending ÷ withdrawal %; annuity PMT spends a PV over a fixed term at a rate.
401(k) save-max vs contribution % Save-max targets the IRS dollar ceiling; contribution % sizes annual save from salary % + match.
Traditional vs Roth Traditional defers tax to withdrawal; Roth pays tax now and grows tax-free (qualified).
RMD vs voluntary withdrawal RMD is a minimum for applicable accounts; you may take more.

❓ Frequently Asked Questions

Is the nest-egg 4% rule a guarantee?

No. It is a planning heuristic. Adjust for fees, taxes, longevity, and market path risk—and confirm with a professional.

Are IRS 401(k) limits fixed in the save-max tool?

No. Enter the elective deferral and catch-up limits for the year you are planning; IRS publishes updates annually.

Is the Social Security estimator official?

No. Start from your SSA FRA estimate, then this tool applies approximate early/delay percentages. Use SSA.gov for personalized figures.

Where do loan and paycheck tools live?
