Years until retirement

years = retirement_age − current_age

65 − 35

= 30 years

Compounding works on time first, contributions second. Each extra year roughly doubles your final balance at typical equity returns.

2

Total monthly contribution (with employer match)

Total PMT = employee + employer_match

$800 + $225

= $1,025/mo — $3K/yr employer match

Employer match is an immediate 100% return — never leave it on the table. 2024 401(k) employee deferral limit: $23,000 ($30,500 if 50+).

Projected balance at retirement (Future Value formula)

FV = PV×(1+r)ⁿ + PMT×((1+r)ⁿ−1)/r

PV=$85K, r=0.0058%/mo, n=360 months, PMT=$1,025

= $1.9M

At 7% annual return over 30 years. Two terms: existing savings compounding (PV growth) plus new contributions compounding (annuity formula).

4

Monthly income from portfolio (4% rule)

Monthly income = Projected Balance × 4% ÷ 12

$1.9M × 0.04 ÷ 12

= $6,468/mo

The 4% rule (Trinity Study, 1998) found that a 60/40 stock-bond portfolio survived 30-year retirements at 4% inflation-adjusted withdrawals in 95%+ of historical scenarios.

Cooley/Hubbard/Walz (1998) — Trinity Study; Bengen (1994) — SAFEMAX

5

Total retirement income

Total = portfolio income + Social Security + other

$6,468 + $1,800 + $0

= $8,268/mo

Social Security replaces ~40% of pre-retirement income for the average earner. Get your personalized estimate at ssa.gov/myaccount.

6

Income gap

Gap = monthly expenses − total income

$4,500 − $8,268

= $3,768/mo surplus

You're projected to have a surplus — consider Roth conversions in low-income early-retirement years to reduce future RMDs.

Key insight

The 4% rule comes from the Trinity Study (1998) — portfolios at 60/40 stock/bond mix survived 30-year retirements at 4% annual withdrawals in 95%+ of historical scenarios.
