What is 401(k) contribution?

A 401(k) contribution is money you put into your employer's retirement plan straight from your paycheck.

Traditional 401(k) contributions are pre-tax for income tax; Roth 401(k) contributions are after tax. Both are capped each year by IRS limits.

An employer match, if any, usually appears separately and doesn't reduce your pay.
