Go-Go, Slow-Go, No-Go: Why Retirement Spending Isn't a Straight Line

One of my favorite clients, a retired engineer in Mesa, used to track his retirement budget like he tracked everything else: one flat number, adjusted for inflation, projected out to age 95 in a tidy spreadsheet. “This is what we’ll spend every year,” he told me proudly. I gently pushed back: “Will you really be golfing in Scotland and taking the grandkids to Hawaii at 88 the same way you will at 68?” He paused. We both knew the answer. Real retirement spending almost never follows a straight line.

There’s a useful framework, often called the Go-Go, Slow-Go, and No-Go years, that describes how spending actually evolves across retirement. Understanding it can change how you plan, how you withdraw, and frankly, how much joy you get out of the money you worked so hard to save.

The Three Phases of Retirement Spending

The Go-Go Years

These are typically your early retirement years, often your sixties and into your seventies, when you’re healthy, energetic, and finally have time. This is when people travel, take up new hobbies, renovate the house, spoil grandkids, and check items off the bucket list. For many Arizona retirees, the Go-Go years are the most expensive of all, and they should be. You’ve earned them, and you’ll never be younger or more able to enjoy them.

The Slow-Go Years

Somewhere in the mid-to-late seventies, for many people, the pace naturally eases. The big trips become less frequent. You’re still active, still social, but you’re more likely to enjoy a quiet morning in Prescott or dinner with friends in Scottsdale than to book a three-week international adventure. Discretionary spending tends to drift downward, often meaningfully, even as everyday expenses stay steady.

The No-Go Years

In the later years, travel and big discretionary outlays usually fall off considerably. But, and this is important, spending doesn’t necessarily drop overall, because healthcare and potential long-term care costs can rise to fill the gap. The composition of your spending shifts from experiences to care. Planning for this phase is less about fun money and more about protecting against large, unpredictable medical costs.

Why the Straight-Line Assumption Hurts You

When you assume flat, inflation-adjusted spending for 30 years, you often end up planning to spend the least exactly when you’re most able to enjoy it, and you may scare yourself into under-spending in your healthiest years out of fear. I’ve seen retirees with $2.5 million sitting on their hands at 68, terrified to take the trip, only to slow down at 80 with the money still untouched.

The flip side is also true. Some people front-load too aggressively without a plan for the No-Go years and get caught short when care costs arrive. The goal isn’t to spend recklessly early or hoard fearfully throughout, it’s to match your spending to the life you’ll actually live.

Front-Loading Experiences (On Purpose)

Once you internalize the phases, a thoughtful strategy emerges: intentionally allocate more of your discretionary budget to the Go-Go years. If the data and your own experience suggest spending naturally declines later, you can plan a higher withdrawal rate early, knowing it’s likely to taper.

For example, a couple might decide their first ten years of retirement include a generous “experiences budget”, the cruises, the family reunions, the second home in Flagstaff for the summers, with a clear understanding that this elevated spending is temporary by design. Done deliberately and within a tested plan, front-loading isn’t reckless. It’s aligning your money with your one finite resource: time.

Flexible Withdrawals Beat Rigid Rules

The old “take 4% and adjust for inflation forever” guideline is a useful starting point, but it assumes a straight line, which we’ve just established rarely happens. A more realistic approach uses flexible, dynamic withdrawals:

• Spend a bit more in strong market years, and trim discretionary spending in down years to protect the portfolio.
• Build in “guardrails”, predefined upper and lower spending limits, so you know in advance when to adjust rather than panicking.
• Plan spending by phase, budgeting more for the Go-Go years and shifting the reserve toward healthcare in the later ones.
• Keep a cash buffer so you’re never forced to sell investments at the worst possible moment.

Modeling these phases and guardrails is exactly what our safe withdrawal rate simulator is built for. Rather than assuming a flat line to 95, you can test what happens when spending is higher early and tapers later, and see whether your plan still holds up across a range of market outcomes. It’s often reassuring: many people discover they can safely enjoy more in their early retirement than they feared.

The Healthcare Reality of the No-Go Years

A realistic plan reserves resources for the later phase, when medical and potential long-term care costs can climb. This doesn’t mean living in fear, it means earmarking a portion of your portfolio as a healthcare reserve so that splurging in the Go-Go years doesn’t leave you exposed later. The peace of mind that comes from knowing that reserve exists is often what frees people to spend confidently early on.

Because this involves taxes, withdrawal sequencing, and risk all at once, it’s a natural place for objective guidance.

The Bottom Line

Retirement spending isn’t a flat line, it’s a curve that usually peaks in your active Go-Go years, eases through the Slow-Go years, and shifts toward care in the No-Go years. Planning as if you’ll spend the same amount at 88 as at 68 often means under-living your best years or under-preparing for your most vulnerable ones. With phase-based budgeting and flexible withdrawals, you can spend with confidence early and stay protected later.
