A 401(k) calculator should show both sides of the decision: how much you save for retirement and how much your paycheck changes today.
The table compares 0%, 5%, 10%, and 15% contribution rates so you can choose a savings rate that fits your budget without ignoring tax savings.
Less than the contribution amount, because a traditional 401(k) lowers income tax withholding. The exact paycheck impact depends on income, filing status, state tax, and pay frequency.
Traditional 401(k) contributions generally do not reduce Social Security or Medicare wages.
