A 401(k) is a straightforward, tax-advantaged way to save for retirement, and if your employer offers one, it’s wise to take advantage of it. However, determining how much to contribute can be challenging. Factors like your age, employer matching contributions, and how your salary compares to your expenses can help guide your decision.

How Much Should You Contribute to Your 401(k)?

401(k) contributions are typically expressed as a percentage of your gross income, which is your earnings before taxes and deductions. The right contribution rate varies depending on your circumstances.

1. Age When You Start Saving

The earlier you start contributing, the more time your investments have to grow.

In your 20s: Starting with a 6% contribution rate is a great option. Experts recommend increasing this by 1% annually until reaching the maximum contribution limit.
In your 40s or 50s: If you’re starting later, aim to contribute at least 15% of your income or as much as the IRS allows. For 2025, the annual 401(k) contribution limit is $23,500 ($31,000 if you're over 50).

2. Employer Matching Contributions

Employer matches are essentially free money added to your 401(k). Typically, employers might:

Match 100% of your contributions up to 3% of your salary.
Then match 50% on the next 2%.

For example, if you earn $60,000 and contribute 5% of your salary ($3,000 annually), you might receive an additional $2,400 from your employer.

3. Income Versus Expenses

If your budget is tight, saving even a small amount is beneficial. Starting with $25 or $50 a month can still grow significantly over time due to compounding returns. As your income increases, you can raise your contributions.

Tips for Increasing Contributions

If you need to start small, here are strategies to gradually raise your contribution rate:

Use auto-escalation: Some plans automatically increase your contribution rate over time, especially during annual raises.
Control lifestyle inflation: Avoid increasing spending when you get a raise, and direct those funds to your 401(k).
Reduce expenses: Review your budget to identify areas where you can cut back and allocate the savings toward retirement.

Also, remember that 401(k) contributions are made before taxes, so the impact on your take-home pay is less than the full contribution amount.

401(k) Balance Milestones by Age

Setting savings milestones can help you track your progress, although these goals are often estimates. One method is to set a retirement savings target and work backward to identify benchmarks for different ages, such as 30, 40, or 50.

While predicting your exact retirement needs can be difficult, consistent saving and incremental increases in your contributions will set you on the right path.
