401(k) Early Withdrawal Penalty Calculator

A 401k early withdrawal calculator shows the actual cost of withdrawing money ahead of schedule. If you make withdrawals from a traditional 401k account before age 59½, there is usually a 10% penalty in addition to regular income tax.

By entering the withdrawal amount, age and various tax rates, federal taxes, state taxes, penalty and net income are calculated. If long term effects are indicated, future lost interest earnings from not investing the money in an account can also be estimated.

Cases where early withdrawal from a 401k is possible.

When money is withdrawn from a traditional 401(k), 403(b) or governmental 457(b) plan before age 59½, it's considered an early distribution. The IRS will count the amount as part of your taxable income for that year and tack on a 10% penalty.

The calculation method can vary depending on the type of plan and the situation. Roth 401(k) plans allow for tax-free withdrawals of contributions, and there are several exceptions to penalties. Unless explicitly stated that an exception applies, this calculator assumes that all withdrawals from traditional accounts are subject to taxation.

Three costs that occur with early withdrawal:

At most three types of charges will be deducted from the withdrawn funds and the remaining amount is available to the account holder.

First, the federal income tax is levied. The withdrawal amount is added to other earnings and taxed at the marginal rate. The highest tax rate is 37 percent.

Next come state and local income taxes. In states without an income tax, the rate is zero, but for those with the highest rates it's more than 13 percent, and some cities levy additional taxes.

Finally, there is a 10% penalty. Unlike income tax, this is a flat rate that applies to the entire withdrawal amount. It only applies to those under age 59 who do not meet any of the exceptions.

How to use this calculator:

First enter the withdrawal amount, current age and federal marginal tax rate. If state or local income taxes apply, also enter those rates. The results area will show the tax amounts, penalty, total cost and final net amount.

If the conditions for penalty relief are met then activating the relevant option will remove penalties by 10%. Income tax however remains. To see a more comprehensive impact activate long term costs and input expected return and retirement age. If money stays in account you can calculate how much it could potentially grow to in future.

Calculation formula:

The actual amount you will have left is what's left after income tax and penalties are taken out of the withdrawal.

W is the amount withdrawn, t_f, t_s and t_l are the tax rates (federal, state and local) entered as decimals, and p is the penalty rate. The penalty rate is .10 for those under 59.5 years old while it's 0 if there is an age requirement or exception. If W = $20,000, t_f = 22%, t_s = 5% (assuming no local tax), and the age at withdrawal is 45, then:

The actual remaining amount is 12600 while the original withdrawn amount was 20,000. So the actual cost is 37 percent. The following table shows the inputs and values used in this example.

Exceptions where penalties are waived for 10%.

There are also several exceptions for those under the age of 59 ½ that allow you to avoid penalties. While income tax will be due, there is no additional 10% penalty.

The most common rule is the "Rule of 55." If an employee leaves their job in or after the year they turn 55, they can withdraw money from their employer's retirement plan without penalty. Some government employees and other public servants may be subject to lower age limits (such as 50) or a minimum service period of 25 years.

In addition to the above, exceptions include but are not limited to total and permanent disability, medical expenses that exceed a certain percentage of adjusted gross income, a series of substantially equal periodic payments, qualified birth or adoption assistance grants of less than $5,000, military reservist pay withholdings collected by the IRS, and distributions to beneficiaries upon death of the account holder. Please refer to the most current list of exceptions published by the IRS for detailed information on the respective requirements.

Withholding tax obligation for 20%

If the distributable capital is received in cash, the plan administrator must immediately withhold federal taxes at a 20 percent rate and remit it to the IRS. This is an advance on your tax bill, not the final amount of tax due.

If the actual amount of taxes and penalties is less than the amount withheld, you will get a refund for the difference when you file your income tax return. If it's more, then you'll have to pay the extra amount. Since withholding does not include state taxes, make sure that you set aside separate funds if this deduction is taxable in your home state.

Hidden costs: Losses through missed income

Taxes and penalties are only the obvious losses; larger costs often come from not leaving money invested until retirement, thus missing out on growth potential.

If you invest $20,000 for 25 years at a 7% annual interest rate, it could eventually reach about $108,500. If you take the money out early, not only will you have to pay current taxes and penalties of $7,400, but you'll also lose potential future growth of about $88,500. A long-term impact chart allows you to see the amounts using your own data.

Alternative options you should consider before cashing out:

Because the total cost can be high, it's wise to consider other options before withdrawing the money.

If your plan allows it, you can use a hardship withdrawal to take the money for specific purposes, but this is subject to income tax and usually also a penalty. If you leave your balance in the original plan or roll it over into an IRA when you change jobs, you can defer taxes and continue earning interest.
