A calculator for 401k early withdrawals is available at the website of Wells Fargo at WellsFargo.com. The calculator requires six values to work. These are the amount considered for early withdrawal, federal and state income tax rates, the age and the retirement year of the user, and the expected return rate.
Once all fields are filled, users can click the blue Estimate the Costs button to get the results of the calculation. Wells Fargo provides detailed information about the financial terms used in the calculator. Hovering over any of the terms brings up a pop-up box with an explanation of the term. Wells Fargo warns that the calculator should only be used for illustrative and estimation purposes as the accuracy of the results may change according to the user's financial circumstances.
