If you're in your 20s and thinking about retirement savings, you're already ahead of most Americans. According to a National Institute on Retirement Security study, two-thirds of working millennials have nothing saved for retirement. Starting now — even with small amounts — puts you at a massive advantage.
Why Starting in Your 20s Is a Superpower
The reason is one word: compounding. When your investments earn returns, those returns earn their own returns. Over decades, this creates exponential growth.
Here's a comparison that illustrates the power:
- Person A starts investing $300/month at age 25, stops at 35 (10 years, $36,000 total invested)
- Person B starts investing $300/month at age 35, continues until 65 (30 years, $108,000 total invested)
Assuming a 7% average annual return, Person A ends up with $610,000 at age 65 — while Person B ends up with $340,000. Person A invested one-third the money but ended up with nearly twice as much. That's the power of starting early.
Step-by-Step: How to Start
1. Get the Free Money First
If your employer offers a 401(k) match, contribute at least enough to get the full match. A typical match is 50% of contributions up to 6% of your salary. On a $50,000 salary, that's $1,500/year in free money.
2. Open a Roth IRA
A Roth IRA is ideal for young earners. You contribute after-tax money now (when your tax rate is likely the lowest it'll ever be), and everything grows tax-free forever. The 2026 limit is $7,000/year.
3. Start with What You Can Afford
You don't need to max out anything immediately. Even $50/month is $600/year. The habit matters more than the amount. Increase your contributions by 1% every time you get a raise.
4. Invest, Don't Just Save
Money in a savings account earning 4% will lose purchasing power to inflation over decades. In your 20s, you can afford to invest aggressively — a simple target-date fund or S&P 500 index fund is a great starting point.
But What About Student Loans?
This is the #1 objection from twenty-somethings. The answer depends on your interest rate:
- Federal loans under 5%: Make minimum payments and invest the rest. Your investment returns will likely exceed the loan interest over time.
- Private loans over 7%: Focus on paying these off aggressively first using the Debt Payoff Calculator, then redirect those payments to retirement.
- In between: Split the difference — pay a bit extra on loans while contributing enough to get any employer match.
How Much Should You Aim For?
The standard guideline is to save 15% of your gross income for retirement (including any employer match). If that feels impossible right now, start with 5–6% and increase from there.

The Bottom Line
Your 20s are the most powerful decade for building retirement wealth — not because you'll save the most money, but because every dollar has the most time to grow. Start small, be consistent, and let compounding do the heavy lifting.
