Go-Go, Go-Slow, No-Go: Why Your Retirement Spending Plan Is Probably Backwards

There’s a pervasive assumption buried in nearly every retirement calculator: that you’ll spend roughly the same amount every year of retirement.

It’s a convenient assumption. It makes the math simple. And it’s completely disconnected from how actual retirees spend money.

Research from the Bureau of Labor Statistics, financial planning firms, and behavioral economists consistently reveals a pattern most retirees don’t anticipate: spending that peaks early, declines through middle retirement, then may surge again for end-of-life care.

Understanding this pattern could mean the difference between unnecessarily restricting your “go-go years” and confidently enjoying the retirement you’ve worked decades to achieve.

The Three Phases of Retirement Spending

Financial planners have long recognized that retirement isn’t a monolithic 30-year period. It’s three distinct phases, each with different spending patterns and lifestyle characteristics.

Phase 1: The Go-Go Years (Typically ages 60-75)

These are the “active retirement” years—when health, energy, and motivation align to make significant experiences possible. Retirees in this phase are:

Traveling extensively (often internationally)
Pursuing active hobbies (golf, hiking, sailing)
Dining out frequently
Attending events and social gatherings
Potentially relocating or renovating homes
Helping adult children financially

Research from T. Rowe Price shows spending during this phase typically runs 20-30% higher than during later phases. Yet most retirement calculators assume flat spending—potentially restricting these prime years unnecessarily.

Phase 2: The Go-Slow Years (Typically ages 75-85)

As energy levels decline and health issues emerge, spending naturally decreases. Retirees in this phase are:

Traveling less frequently and less ambitiously
Spending more time at home
Reducing expensive hobbies
Declining social invitations
Simplifying lifestyle

The natural spending decrease during these years often exceeds 20% from peak go-go levels—even without conscious budget adjustments.

Phase 3: The No-Go Years (Typically 85+)

In the final retirement phase, mobility and independence often decline significantly. Spending may:

Continue declining for discretionary items
Potentially surge for healthcare and long-term care
Shift heavily toward caregiving and medical expenses

This phase introduces the greatest uncertainty: some retirees maintain independence into their 90s with minimal healthcare costs, while others face hundreds of thousands in long-term care expenses.

Why This Pattern Matters for Early Retirees

For the FIRE community, this spending pattern has profound implications.

Implication 1: Your Most Active Years Happen First

If you’re retiring at 45 or 50, your “go-go years” begin immediately. The energy and health required for ambitious travel, active pursuits, and bucket-list experiences won’t improve with time—it will gradually decline.

Excessive frugality during these years means trading experiences you can have now for hypothetical spending capacity you may not need later.

Implication 2: Sequence of Returns Risk Cuts Both Ways

Early retirees worry (correctly) about sequence of returns risk depleting portfolios during early years. But there’s a countervailing factor: if spending naturally declines during years 15-30 of retirement, the long-term withdrawal pressure may be less severe than static models suggest.

Implication 3: The Traditional 4% Rule Assumes Flat Spending

The 4% rule (and even Bengen’s updated 4.7% recommendation) assumes inflation-adjusted withdrawals that stay constant throughout retirement. Real spending patterns suggest this is unnecessarily conservative during late retirement—and potentially too aggressive during early retirement.

Dynamic Withdrawal Strategies: Spending Smarter, Not Less

The recognition that retirement spending isn’t flat has produced several alternative withdrawal strategies:

The Guardrails Approach

Developed by financial planner Jonathan Guyton, this method sets upper and lower “guardrails” around your withdrawal rate. Research cited by Kitces and others shows this approach can support higher initial withdrawals with appropriate flexibility.

How it works:

Start with a base withdrawal rate (say, 5%)
If portfolio gains push your rate below 4%, increase spending
If losses push your rate above 6%, decrease spending
The flexibility allows adaptation to actual market conditions

The “Spend More Now” Approach

Some planners now advocate front-loading retirement spending intentionally. The logic: guaranteed healthy years early in retirement are more valuable than hypothetical spending in uncertain later years.

Michael Kitces and others have demonstrated that retirees who maintain rigid 4% spending “will most commonly just leave a huge amount of money left over”—money that could have funded experiences during years of health and vitality.

The Bucket Strategy

This approach segments retirement assets into “buckets” for different time horizons:

Bucket 1 (0-5 years): Cash and bonds for immediate needs
Bucket 2 (5-15 years): Moderate allocation for go-slow years
Bucket 3 (15+ years): Aggressive allocation for long-term growth

The psychological benefit: knowing near-term needs are covered allows retirees to maintain equity exposure without panic-selling during downturns.

What the Research Actually Shows

Studies of real retiree spending confirm the go-go/go-slow/no-go pattern:

Bureau of Labor Statistics Data Household spending for those 65-74 averages $52,141 annually, dropping to $41,471 for ages 75 and older—a 20% natural decline.

Health Transition Study Research tracking retirees over time shows spending velocity decreasing roughly 1-2% per year in real terms after age 70, accelerating to 3-4% after age 80—even among healthy retirees.

The “Spending Smile” When plotting spending across retirement, many analysts observe a “smile” pattern: high early spending, lower mid-retirement spending, then potentially higher late-retirement spending for healthcare. Planning for this curve—rather than a straight line—can dramatically change optimal strategy.

How Monte Carlo Analysis Captures Spending Variability

Static retirement calculators fail to model the spending curve. They assume $60,000 at age 65 means $60,000 (inflation-adjusted) at age 85.

Advanced Monte Carlo simulation can model variable spending across retirement phases:

Higher spending during go-go years
Natural decline during go-slow years
Potential healthcare surge during no-go years
Flexibility to adjust based on portfolio performance

The result: probability-based guidance that reflects how retirement actually unfolds, not how spreadsheets assume it does.

A Framework for Planning Your Phases

Here’s how to integrate phase-based thinking into your retirement strategy:

Step 1: Project Your Phases Based on health, family history, and lifestyle, estimate when your transitions might occur. Be realistic—most 50-year-olds underestimate how 75 will feel.

Step 2: Front-Load Experiences Identify bucket-list items requiring physical capability or significant travel. Plan to accomplish these during go-go years rather than “someday.”

Step 3: Build in Flexibility Rather than rigid withdrawal rules, adopt strategies that allow higher early spending while preserving ability to reduce if markets struggle.

Step 4: Plan for Healthcare Uncertainty The no-go phase introduces the greatest spending uncertainty. Long-term care insurance, health savings accounts, and adequate portfolio reserves can manage this risk.

Step 5: Model Multiple Scenarios Test your plan against both flat spending assumptions and realistic phase-based curves. The difference often reveals unnecessary conservatism—or dangerous optimism.

The Psychology of Permission

Beyond the math, there’s a psychological dimension to phase-based planning: giving yourself permission to spend.

Research highlighted in the “Spend Your Retirement Money” publication reveals a counterintuitive problem: most retirees underspend. They accumulated for decades, built frugal habits, and struggle to flip the switch to spending mode.

Understanding the go-go/go-slow/no-go framework provides an evidence-based rationale for spending during your most capable years. You’re not being irresponsible—you’re aligning spending with the reality of how retirement unfolds.

The Bottom Line: Retirement Spending Has a Shape

Flat-line spending assumptions make for simple math and sleepless nights. They encourage excessive frugality during healthy years and ignore the natural decline that occurs later.

Phase-based planning acknowledges reality: your retirement spending will follow a curve, not a line. The retirees who understand this curve can confidently spend more during go-go years while maintaining security for whatever the no-go years bring.

The question isn’t how much you’ll spend in retirement. It’s when you’ll spend it—and whether your plan accounts for the natural rhythm of retirement life.
