Money saved in your 20s has decades to compound, which means even small, consistent contributions now can outgrow much larger amounts started later. The specific accounts matter less than simply starting.
Start with a free match, if you have one
If your employer offers a 401(k) match, contributing enough to get the full match should almost always come first — it's an immediate, guaranteed return on your money that no other investment can match.
Roth vs. traditional accounts
| Roth (IRA or 401k) | Traditional (IRA or 401k) | |
|---|---|---|
| Tax treatment now | Contribute after-tax | Contribute pre-tax, lowers taxable income |
| Tax treatment in retirement | Withdrawals are tax-free | Withdrawals are taxed as income |
| Often favored when | You're in a lower tax bracket now than you expect in retirement | You're in a higher tax bracket now and want the current deduction |
Why your 20s specifically matter so much
If you can't max anything out yet
- Contribute something, even 1-3% of your paycheck — the habit matters more than the amount at first.
- Increase your contribution percentage every time you get a raise, before the extra income gets absorbed into spending.
- Automate it so the decision only has to be made once.
Don't overlook an HSA if you have one
If you're enrolled in a high-deductible health plan with a Health Savings Account, it doubles as one of the most tax-efficient retirement tools available — contributions are pre-tax, growth is tax-free, and withdrawals for medical expenses are also tax-free. After age 65, you can withdraw for any reason and simply pay ordinary income tax, functioning much like a traditional IRA.
