Ritholtz Wealth Management’s 401(k) rollover calculator estimates what may remain after tax if you cash out a 401(k) or roll it over.
Enter your balance, age, tax rate, return assumption and time horizon, then treat the output as an illustration, not a forecast.
How the 401(k) rollover calculator makes its estimate
The calculator removes your combined income-tax rate and, before age 59½, the 10% early-withdrawal penalty from a cash-out balance. It grows that smaller amount in a taxable account, while the rollover keeps the full balance invested tax-deferred and applies the entered tax rate when the money is withdrawn.
At age 45, a hypothetical $120,000 balance leaves $81,600 after 22% income tax and a 10% penalty: $120,000 − $26,400 − $12,000. The values later show how starting with less money can compound into a much wider gap over 20 years.
Real investments can lose money, including money originally invested, and a 6% assumption is not a promised result.
When a result should make you pause
A higher rollover value usually reflects two plain advantages: more money stays invested at the start, and taxes are postponed. A close result deserves a second look at the time horizon, age, tax assumptions and the reason cash is needed; it does not automatically make a cash-out sensible.
For an engineer who likes to pressure-test the inputs, run the estimate twice. Use a modest return and then a higher combined tax rate. If cashing out still creates a five-figure shortfall and there is no immediate unavoidable need for the money, keep the rollover option open while you review the paperwork.
- Good result: The rollover remains ahead under several reasonable assumptions.
- Worrying result: A small gap may mean the horizon or inputs need review.
What Ritholtz Wealth Management adds beyond the model
The calculator cannot inspect the plan’s distribution choices, the investments already held in other accounts or the spending date that turns a long horizon into a short one. Ritholtz Wealth Management reviews those facts together before treating a calculated difference as a decision.
Ritholtz Wealth Management uses long-term research and diversification, not a market call, when reviewing rollover choices. Before suggesting an investment change, we put sale and withdrawal taxes on paper and compare the account’s role against your 401(k), IRA and taxable holdings. A rollover is not automatically worthwhile if the new account creates a worse investment setup or you need cash for a near-term obligation.
- Account destination: Confirm that the receiving account accepts the rollover.
- Tax estimate: Check the rate used now and the rate expected at withdrawal.
Your questions about Ritholtz Wealth Management, answered
Does cashing out a 401(k) always create a 10% penalty?
No. This calculator applies the 10% early-withdrawal penalty before age 59½ because that is the usual treatment, but federal tax law includes exceptions. An exception can depend on why the money is withdrawn and details of the plan, so confirm the treatment before acting on a cash-out estimate.
Why does the rollover result usually come out higher?
The rollover result is usually higher because the entire balance keeps compounding before tax is paid. A cash-out begins with a smaller balance after income tax and, for an early withdrawal, the penalty. The calculator applies the same return assumption to compare the effect of those starting amounts.
Can this calculator compare a rollover to a new employer’s plan?
Yes. A 401(k) rollover calculator can help compare keeping retirement money invested with taking a taxable cash distribution, regardless of the intended receiving account. Check that the new plan accepts rollovers, then compare its investment choices, account costs and withdrawal options with the alternatives.
Should a large rollover advantage settle the decision?
No. A large rollover advantage is a useful warning about taxes and lost compounding, not a complete answer. Ritholtz Wealth Management would also look at near-term cash needs, debt terms, other available savings and the investment mix across your accounts before drawing down retirement money.
One input that can bend the comparison
The combined income-tax rate is often entered too low because people use only their federal rate and forget state income tax where it applies. On a $120,000 cash-out before age 59½, changing the tax input from 22% to 32% cuts the immediate amount from $81,600 to $69,600.
Use the rate you would actually pay on additional income, not a favorite number from an old return. Some states tax retirement income differently, so check your state’s rules before treating the calculator result as a withdrawal plan.
