Employed individuals can use a 401(k) calculator to determine how a pre-tax contribution to a retirement savings account can impact their take-home pay, according to Fidelity Investments. The tool calculates the difference in take-home pay and how it may change if money is deducted from a paycheck before income taxes are calculated. This calculation is based on five major varying factors.
Annual gross salary is a person’s total annual salary before any deductions are taken out, as explained by Fidelity Investments. A pay period refers to how frequently an employer pays an employee. A contribution rate is the percentage of a person’s salary that goes toward the retirement account. Federal income tax rates and state tax rates are also necessary to determine total take-home pay.
Ultimately, the calculations show the total take-home pay amount. However, users can also leverage the tool to determine how to increase take-home pay by contributing money to a 401(k) as opposed to putting the same amount into a taxable account, according to Fidelity Investments.Learn more about Salaries
