In 1980, about 38% of private-sector workers could count on a traditional pension. By 2020, that number had dropped to 15%, replaced by 401(k)s and similar plans where the responsibility for saving and investing falls squarely on the individual. This shift has left many retirees wishing they had known earlier what they know now.
If you’re in your 20s or 30s, you have a golden opportunity to avoid the most common retirement-saving regrets. Here are the lessons that veteran savers and financial planners wish they could tell their younger selves.
The Most Common Regret: Not Starting Sooner
The most frequent lament among retirees is not starting to save earlier. The math is stark: A 25-year-old who invests $5,000 per year at a 7% real return will accumulate about $1.1 million by age 65. Start at 35, and the same annual contribution yields only around $472,000. That’s a difference of more than 2x, purely due to time.
Compound interest is often called the eighth wonder of the world, but it only works if you give it time. The first decade of saving is the most powerful because those dollars have the longest to grow. Even small amounts, like $50 a month, can snowball into a six-figure sum over four decades. The key is to start now, not to wait until you feel you have ‘enough’ to save.
The 4% Rule May Be Too Aggressive Today
The 4% rule — withdraw 4% of your portfolio in the first year of retirement, then adjust for inflation — was derived from historical data that suggested it would make your savings last 30 years. But recent research, including work by Wade Pfau, suggests a safer withdrawal rate is 3% to 3.5%, especially in a low-yield environment.
Why? Because the rule assumes a portfolio of 50% stocks and 50% bonds, and it doesn’t account for prolonged periods of low returns or high inflation. If you retire into a bear market and withdraw too much early on, you can dramatically reduce your portfolio’s longevity. A more conservative withdrawal rate can help ensure you don’t outlive your money.
The Real Cost of Healthcare in Retirement
Fidelity estimates that a 65-year-old couple retiring in 2024 will need about $165,000 (after-tax) just for medical expenses in retirement — and that doesn’t include long-term care. Many retirees are blindsided by these costs, which can derail even a well-planned retirement.
Medicare covers a lot, but not everything. There are premiums, deductibles, copays, and services like dental, vision, and hearing aids that aren’t covered. Long-term care is even more expensive, and Medicare doesn’t cover most of it. To prepare, consider saving in a Health Savings Account (HSA) if you’re eligible, and look into long-term care insurance.
Social Security: The Timing Matters More Than You Think
Your Social Security claiming age has a huge impact on your monthly benefit. Claiming at 62, the earliest age, reduces your benefit by about 30% compared to waiting until Full Retirement Age (FRA), which is 67 for those born in 1960 or later. Delaying to 70 increases your benefit by about 24% over FRA.
For a couple, the decision is even more complex because it affects survivor benefits. The higher-earning spouse should generally delay as long as possible to maximize the survivor’s benefit. But he says, ‘It’s not just about your own lifespan; it’s about the survivor’s.’
The Psychology of Saving: Why We Fail
Why do so many people fail to save enough? Behavioral economists point to present bias — our tendency to prioritize immediate gratification over long-term goals. That’s why automatic enrollment in retirement plans is so effective: it works with our natural inertia.
Plans with auto-enrollment see participation rates above 90%, versus about 50% for opt-in plans. If your employer offers automatic escalation, where your contribution rate increases automatically each year, take advantage of it. It’s a painless way to increase your savings over time.
Another common pitfall is loss aversion. When the market drops, we panic and sell, locking in losses. But historically, the market has recovered from every major downturn. In 2008, the S&P 500 dropped over 40%, but it recovered. The key is to stay invested and not try to time the market.
The Math of Employer Matches
The average employer match is about 4–5% of salary, often matching 50% of the first 6% of pay. Not contributing enough to get the full match is literally leaving free money on the table. If you earn $60,000 and your employer matches 50% of the first 6%, that’s up to $1,800 per year in free money. Over 30 years, with investment growth, that could be worth over $150,000.
If you’re not contributing at least up to the match, you’re missing out on an immediate 50% return on your investment. That’s a better return than almost any other investment out there.
The Cost of Waiting to Learn About Investing
Financial literacy is low — only about a third of Americans can correctly answer basic questions about interest, inflation, and diversification. But you don’t need to be an expert. Low-cost index funds, like those tracking the S&P 500, have expense ratios as low as 0.03% to 0.10%, compared to the 1–2% of actively managed funds in the 1990s. That difference in fees can cost you tens of thousands of dollars over a career.
The best move is to start with a simple target-date fund or a three-fund portfolio. You can learn more as you go, but the most important step is to begin. Remember, time in the market beats timing the market.
The earlier you start, the more time compound interest has to work. But it’s never too late to make positive changes. Whether you’re 25 or 55, maximize your employer match, consider automatic enrollment, and be mindful of withdrawal rates and healthcare costs. The decisions you make today will shape your retirement tomorrow.
Summary
- Start early: The difference between starting at 25 vs. 35 is more than 2x in final savings.
- Know your withdrawal rate: The 4% rule may be too aggressive; 3–3.5% might be safer.
- Healthcare costs: Budget for ~$165,000 for a couple’s medical expenses in retirement.
- Social Security timing: Claiming at 62 vs. 70 changes your benefit by over 50%.
- Maximize your employer match: It’s free money — contributing at least up to the match is a no-brainer.
FAQ
Q: What is the best way to start saving for retirement if I’m in my 20s?
A: Start with your employer’s 401(k) plan, especially if there’s a match. Contribute at least enough to get the full match. If you don’t have a 401(k), open an IRA. The key is to start now, even if it’s a small amount.
Q: How much should I have saved by age 30?
A: A common rule of thumb is to have the equivalent of your annual salary saved by 30. But don’t be discouraged if you’re behind — start increasing your savings rate now.
Q: Is it better to save in a Roth or traditional 401(k)?
A: It depends on your current tax bracket vs. your expected bracket in retirement. If you think you’ll be in a higher bracket later, Roth may be better. Many people choose to diversify with both.
Q: What is a required minimum distribution (RMD)?
A: RMDs are the minimum amounts you must withdraw from your traditional 401(k) or IRA starting at age 72 or 73, depending on your birth year. They are subject to income tax.
Q: How can I avoid outliving my savings?
A: Use a conservative withdrawal rate, like 3-3.5%, and consider annuities for guaranteed income. Also, delay Social Security to increase your monthly benefit.
