Advanced FIRE Calculator with Retirement Drawdown, Taxation, and Early Withdrawal Penalties
This calculator projects your portfolio year-by-year, applying contributions before retirement and withdrawals after.
By default, it uses a 4% withdrawal rule (first year of retirement = 4% of total portfolio), then increases that withdrawal each subsequent year by your chosen inflation rate.
Drawdown Logic & 10% Early Withdrawal Penalty:
If you retire before age 60, you must withdraw from Taxable first.
If the Taxable account is depleted, you can withdraw from 401(k) but incur an extra 10% penalty (on top of your effective tax rate).
(This is a simplified approach; there are exceptions you may qualify for.)
Starting at age 60, withdrawals follow the 24% bracket strategy for 401(k), then Roth, and finally Taxable if more is needed.
The 401(k) withdrawal starts at $100k (gross) in the first retirement year to keep you under that 24% tax bracket, growing 1.5% each year in retirement. Anything above that bracket goes to Roth, then Taxable.
The “Effective Tax Rate” applies to 401(k) & Taxable withdrawals, and an additional 10% penalty applies to 401(k) distributions taken before age 60.
