When people begin planning for retirement, one assumption tends to slip in quietly: that expenses will naturally decline. Work-related costs disappear. Commuting ends. Children become financially independent. Fewer obligations should mean lower spending.
Sometimes that’s true. But as a planning foundation, it’s often the wrong place to start.
The issue isn’t whether expenses go down. It’s that retirement spending rarely moves in a straight line. Instead of simply shrinking, it changes shape, and that distinction matters far more than the total number on a spreadsheet.
Some costs fade away. Others become harder to avoid. Payroll taxes and retirement contributions disappear, but healthcare premiums, supplemental insurance, and out-of-pocket medical expenses often rise and arrive regardless of market conditions. Property taxes, insurance, and home maintenance don’t disappear just because paychecks stop. In many cases, they become more rigid at the same time income becomes more flexible.
Spending also tends to become less predictable. Retirement often introduces lumpy expenses rather than smooth ones: major travel early on, home repairs, helping adult children, caring for aging parents, or relocating later in life. These aren’t planning failures; they’re normal features of this phase of life. Plans built on neat averages can underestimate the strain created by uneven cash needs, even when long-term projections appear sound.
There’s also a quieter tension. Many retirees want more flexibility, like the ability to travel while health allows, say yes to opportunities, or support family when needed. Yet plans that rely on “lower expenses” can reduce flexibility elsewhere. Large pre-tax balances may force income through required distributions. Taxes become harder to manage. Withdrawals may need to happen at the wrong time. The plan may look efficient on paper while feeling constrained in practice.
That’s why the most useful retirement question isn’t, “How much less will we spend?” A better starting point is, “What happens if we don’t?”
A resilient retirement plan isn’t one that assumes expenses decline. It’s one that still works if spending stays flat, arrives unevenly, or rises in specific categories. That resilience usually comes from liquidity, tax diversification, and a clear understanding of which expenses are truly essential versus optional.
At Hanover Advisors, we focus less on perfect forecasts and more on building plans that can adapt. Because retirement rarely follows a clean downward curve, and your plan shouldn’t require it to.
If you’re within a few years of retirement, or already there, it may be worth stress-testing your plan against this question. Sometimes a small adjustment in structure can make a meaningful difference in flexibility and confidence over time.
