I've been helping people plan for retirement for years. The same mistakes come up again and again — smart people, good savers, but they hit the same blind spots. Here are the five I see most often, and what you can do about each one.
Common Retirement Planning Mistakes — Impact & Fix
| Mistake | Impact | Fix |
|---|---|---|
| No income plan | High | Map income sources vs. expenses |
| Short time horizon | High | Plan for 30 years minimum |
| Ignoring taxes | Medium | Tax-diversify income sources |
| Claiming SS early | High | Run break-even analysis first |
| No healthcare plan | High | Budget separately, plan 62–65 gap |
Mistake #1: Treating Retirement Like a Date, Not a Process
"I'm retiring on June 30th." Great. But what happens on July 1st?
Too many people fixate on the retirement date without building a retirement plan. They know when they want to stop working, but they haven't figured out where their income comes from, how they'll handle healthcare, what their tax situation looks like, or how they'll spend their time.
Start the planning process at least two to three years before your target date. Retirement is a 20-to-30-year phase of life that requires just as much planning as the career that preceded it.
Mistake #2: Underestimating How Long Retirement Lasts
When I ask someone how long they think retirement will last, they usually say something like "15 or 20 years." But if you retire at 62 and you're in reasonably good health, there's a real chance you'll live to 90 or beyond. That's 28 years. Almost three decades.
Planning for a 15-year retirement and living for 28 years is a recipe for running out of money. I'd rather plan for a 30-year retirement and have money left over than plan for 15 and come up short at 82.
Mistake #3: Ignoring Taxes in Retirement
Here's a surprise for a lot of new retirees: retirement income is taxable. Your 401(k) distributions? Taxed as ordinary income. Social Security? Up to 85% can be taxable depending on your other income. That pension? Fully taxable in California.
Someone who saved $1 million in their 401(k) doesn't have $1 million. After taxes, they might have $700,000–$750,000 in actual spending power. The fix is tax diversification — a mix of taxable, tax-deferred, and Roth accounts to manage your bracket year by year.
Mistake #4: Claiming Social Security Too Early Without a Plan
Someone retires at 62, immediately files for Social Security because "I want to get my money," and locks in a permanently reduced benefit. The issue isn't claiming at 62 per se — sometimes it's the right move. The issue is claiming at 62 without analyzing the alternatives. If you have other income sources that can bridge you for a few years, the math almost always favors waiting.
Mistake #5: Not Having a Healthcare Plan for 62–65
If you retire before 65, you don't have Medicare yet. And private health insurance for a 62-year-old couple in Orange County can easily run $2,000–3,000 per month. That's $24,000–36,000 per year that a lot of people simply don't plan for.
I've had clients who were all set to retire early, and then we ran the healthcare numbers and they went pale. Don't let this be a surprise. Factor it in early, explore your options (COBRA, Covered California, spouse's plan), and make it part of your retirement budget from day one.
The Common Thread
All five of these mistakes have one thing in common: they're avoidable with proper planning. None of this is rocket science. It just takes someone sitting down, looking at your full picture, and thinking through the what-ifs.
