Retirement Savings: 401(k)s, Roth IRAs and How Much to Save

Most Americans save for retirement through a workplace 401(k), an IRA, or both. A 401(k) takes contributions straight from your paycheck, often with an employer match, and traditional contributions lower your taxable income now. A Roth IRA is funded with money you have already paid tax on, and qualified withdrawals in retirement are tax-free. If your employer offers a match, contributing enough to get all of it is usually the first step.

What to know

Retirement: the essentials

Get the full match first

An employer match is part of your pay. If your employer matches, say, half of what you put in up to 6% of salary, contributing less than 6% leaves that money unclaimed.

Roth or traditional is a bet on your tax rate

Traditional contributions save tax now and are taxed when you withdraw. Roth contributions are taxed now and come out tax-free later, so Roth tends to win if you expect a higher tax rate in retirement.

Time does more than the amount

Money invested in your 20s and 30s has decades to compound. The Rule of 72 gives a quick feel for it: at a 7% annual return, money doubles in roughly ten years.

Roth IRAs have income limits

Your ability to contribute to a Roth IRA phases out at higher incomes. For 2026 the phase-out for single filers runs from $153,000 to $168,000.
