What is a 401(k)?

A 401(k) is an employer-sponsored retirement savings plan that allows employees to save for retirement with significant tax advantages. Contributions can be made pre-tax (Traditional 401(k)) or after-tax (Roth 401(k)), and many employers match a portion of employee contributions, effectively providing free money for retirement.

How 401(k) Retirement Planning Works

A **401(k)** is an employer-sponsored retirement savings plan that allows employees to save for retirement with significant tax advantages. Understanding how your 401(k) grows over time is crucial for retirement planning. **Key Components:** 1. **Employee Contributions**: Money you contribute from your paycheck (pre-tax for Traditional 401(k) or after-tax for Roth 401(k)) 2. **Employer Match**: Many employers match a percentage of your contributions (e.g., 50% match up to 6% of salary) 3. **Catch-Up Contributions**: For employees 50 and older, you can contribute additional amounts above the standard limit 4. **Compound Growth**: Your contributions grow tax-deferred (Traditional) or tax-free (Roth), allowing your money to compound over decades **Calculation Methodology:** We calculate your retirement balance using compound interest formulas, accounting for: * Annual contribution limits ($23,000 for 2026, $30,500 with catch-up for 50+) * Employer matching contributions * Expected annual return on investments * Tax treatment (Traditional vs Roth) *Note: All calculations are estimates based on current 2026 IRS limits and assumptions. Actual results will vary based on market performance and plan-specific rules.*

Frequently Asked Questions About 401(k)

Q:What is the 401(k) contribution limit for 2026?

For 2026, the standard 401(k) contribution limit is $23,000 per year. Employees aged 50 and older can make catch-up contributions of an additional $7,500, bringing their total limit to $30,500 per year.

Q:How does employer matching work?

Employer matching varies by company. Common examples include: 50% match up to 6% of salary (if you contribute 6%, employer adds 3%), or dollar-for-dollar match up to 3% (if you contribute 3%, employer adds 3%). Some employers match 100% up to a certain percentage of your salary.

Q:What is the difference between Traditional and Roth 401(k)?

Traditional 401(k) contributions are made with pre-tax dollars, reducing your taxable income now. You pay taxes when you withdraw in retirement. Roth 401(k) contributions are made with after-tax dollars, so you pay taxes now but withdrawals in retirement are tax-free. Both have the same contribution limits.

Q:When can I withdraw from my 401(k) without penalty?

You can withdraw from your 401(k) without the 10% early withdrawal penalty after age 59½. You must start taking Required Minimum Distributions (RMDs) at age 73 (for those who reach age 73 after 2022). Withdrawals before age 59½ typically incur a 10% penalty plus income taxes, with some exceptions like hardship withdrawals or loans.

Q:What happens to my 401(k) if I change jobs?

When you change jobs, you have several options: 1) Leave it with your former employer (if allowed), 2) Roll it over to your new employer's 401(k) plan, 3) Roll it over to an IRA, or 4) Cash it out (not recommended due to taxes and penalties). Rolling over to an IRA or new 401(k) preserves the tax-advantaged status.

Q:Should I contribute to a 401(k) or pay off debt first?

Generally, you should contribute enough to get the full employer match (it's free money), then prioritize high-interest debt. After paying off high-interest debt, maximize your 401(k) contributions. The employer match typically provides an immediate 50-100% return, which is hard to beat.
