Calculation Assumptions

6% mean annual return with 13% volatility assumption.
3% annual inflation rate.

Healthcare bridge costs based on estimated ACA marketplace premiums; actual costs vary by state, age, and plan.
Retirement success defined as portfolio balance > $0 at end of horizon.
The 4% rule and safe withdrawal rates are guidelines, not guarantees. Past performance does not predict future results.

Static math ignores market sequence risk and state taxes.
