Pre-tax balance Balance

Money in traditional 401(k)s and IRAs is taxed as ordinary income when withdrawn, so your spendable income is $42,259, not the $51,535 headline. Roth accounts avoid this — a reason to hold some tax-free savings alongside pre-tax ones.

Frequently asked

Questions about the retirement planner with taxes for a deferred retirement savings plan

Are 401(k) and IRA withdrawals taxed?

Yes — withdrawals from traditional (pre-tax) accounts are taxed as ordinary income. So a $1 million balance provides noticeably less spendable income than the headline figure suggests.

How can I reduce taxes in retirement?

Hold some money in Roth accounts for tax-free withdrawals, manage your taxable income across years, and coordinate withdrawals to stay in lower brackets. Tax diversification helps.

Why plan around after-tax income?

Because your lifestyle is funded by spendable dollars, not pre-tax balances. Planning on the after-tax figure avoids overestimating what your savings will actually support.

Is the Retirement Planner with Taxes for a Deferred Retirement Savings Plan free to use?

Yes. Every calculator on FinCalculators is completely free, with no sign-up, login or paywall. You can run as many scenarios as you like.
