How to Start Saving for Retirement in Your 20s

By The Penny Plan Editorial Team Published July 17, 2026 5 min read

Retirement can feel like an abstraction in your 20s, decades away and hard to picture concretely. That distance is actually the reason starting early matters so much — time is the one ingredient that can’t be added back later.

The quick answer

Starting to save for retirement in your 20s generally means opening whichever account is most accessible — a workplace plan if one’s offered, an IRA if not — setting a contribution rate that fits the current budget, and automating it so it continues without requiring a fresh decision each pay period. The specific dollar amount matters far less at this stage than simply beginning, since decades of potential growth ahead is the single biggest advantage a young saver has over almost anyone starting later.

Start with whatever account is available

The single most useful early step is opening an account, even before deciding on the perfect contribution amount.

Why the early years carry outsized weight

Money invested in your 20s has more years ahead of it for compound growth than the same dollar amount invested a decade later. Because growth builds on previous growth, a contribution made early in a career has meaningfully more time to compound than a larger contribution made later, even though it may feel less significant at the time it’s made.

A modest start is still a real start

There’s a common misconception that retirement saving only counts once contributions reach some meaningful size. In practice, a small, consistent percentage of income started early tends to build a stronger foundation than waiting for a “better” moment that may not arrive on a predictable schedule.

Building the habit alongside other goals

Retirement saving in your 20s rarely happens in isolation — it usually competes with building a cash cushion for emergencies, paying down any student debt, and covering rising living costs. Rather than treating it as all-or-nothing, many people start with a modest contribution rate and increase it gradually as income grows or other obligations ease.

Worth remembering

Nothing about retirement saving in your 20s requires having it all figured out — not the exact account, not the exact contribution rate, not a fully mapped-out plan for the next forty years. What matters most is opening an account, comparing what’s available, and starting a contribution that can realistically continue, since the years this money spends invested are doing more of the work than most people expect at the outset.
