The 10-Year Window That Can Make or Break Your Retirement
Getting these ten years right is crucially important to your retirement success!
Most people think of retirement as a single moment, a date circled on the calendar when they’ve worked their last day and the adventures begin.
But the truth is, retirement is not a day. It’s a decade-long transition, roughly five years before and five years after you stop working.
The decisions that you make in that 10-year window have an outsized impact on the rest of your financial life.
Get those years right, and the rest of retirement tends to unfold calmly and confidently.
Get them wrong, and it can be very problematic.
The Retirement “Red Zone”
Think of this decade as the financial equivalent of takeoff and landing, the moments that require the most precision.
The five years before retirement are about positioning: converting assets into the right mix of liquidity, growth, and tax efficiency.
The five years after are about execution: turning those assets into a reliable, retirement “paycheck” and maximizing tax opportunities available to you.
What happens here determines how long your money lasts, the tax you pay, and how comfortably you’ll sleep along the way.
The Five Years Before Retirement: Preparation and Positioning
In the pre-retirement phase, your goal is to make the shift from accumulation to distribution before you need the income. That means thinking differently about your accounts, your taxes, and your time.
1. Fine-tune your tax strategy.
These are your “golden conversion years.” If your income is temporarily lower, maybe you’re working part-time, or have finished paying for college or the mortgage, consider Roth conversions while you’re paying taxes at lower rates. The years between your final paycheck and your first required minimum distribution (RMD) are prime territory for strategic tax moves.
2. Rethink your portfolio risk.
You don’t have to abandon growth, but you do need balance. Shifting some assets into short- and intermediate-term “buckets” provides stability when markets inevitably pull back. The goal isn’t to outguess the market; it’s to prevent a downturn from derailing your early retirement years.
3. Organize your cash flow.
Start living as if you’re retired — track what you actually spend, test your target budget, and adjust before you lock it in. Build a year’s worth of expenses in cash or cash-like reserves so you’re not forced to sell investments during volatility.
4. Simplify.
Consolidate accounts, update beneficiaries, review estate documents, and ensure your spouse or family can navigate your finances easily. Complexity is an invisible risk.
The Five Years After Retirement: Launch and Adjustment
Once you’ve stepped into retirement, the planning focus shifts from saving for retirement to managing money through it. The first few years establish your long-term trajectory.
1. Create a withdrawal strategy, not random withdrawals.
Which accounts you draw from first matters. Mixing taxable, tax-deferred, and Roth sources intentionally can minimize lifetime taxes and protect against rising rates. Avoid the trap of taking income simply because it’s easy.
2. Protect against “sequence risk.”
Losses early in retirement can compound damage because you’re selling shares while markets are down. Guardrails — spending limits and review points — help you adjust calmly instead of reacting emotionally.
3. Manage healthcare and Medicare decisions.
This is the era of IRMAA surprises, Medigap choices, and premium brackets that can sneak up on high-income retirees. Coordinating withdrawals and conversions around those thresholds can save thousands per year.
4. Give yourself permission to spend.
You’ve trained for decades to save. Now, the work is in learning to use that money well — to spend purposefully, travel, give, and enjoy. A written plan and regular reviews can provide the confidence that you’re not “spending too much,” you’re spending according to plan.
Why This Decade Matters So Much
There are two big reasons this 10-year window defines long-term success: market timing and tax timing.
Market timing (not in the speculative sense) matters because of sequence-of-returns risk: poor returns early in retirement hurt more than poor returns later, simply because withdrawals amplify losses. Protecting your portfolio in those early years gives it room to recover.
Tax timing matters because the government’s rules shift dramatically during this decade — from income tax to RMDs to Social Security and Medicare thresholds. Small, coordinated moves now — Roth conversions, charitable giving, strategic withdrawals — can compound into six-figure lifetime savings.
The retirees who thrive aren’t the ones who chase returns; they’re the ones who manage timing deliberately.
How to Get This Window Right
If you’re within five years of retiring, or newly retired, this is the time to take a holistic view.
Run a 10-year projection that models income, taxes, and spending year by year.
Build a withdrawal policy (like a flight manual) so you know which account funds each phase.
Use tools or planning software that let you stress-test different scenarios — inflation spikes, market declines, longer life expectancy.
Determine the tax planning opportunities that can help you minimize your lifetime retirement tax bill.
Coordinate with your CPA and estate attorney so every move connects.
When all those parts work together, you stop worrying about “what the market does next” and start focusing on what your life looks like next.
The Payoff
The purpose of this decade isn’t just to avoid mistakes, it’s to create freedom for yourself and your family.
Freedom from tax surprises.
Freedom from the anxiety of market headlines.
Freedom to spend confidently because you know the plan behind the numbers.
If you treat the 10 years around retirement as the defining window it is, you can set yourself up for decades of clarity, stability, and calm.
