The True Cost of Retirement That Most People Underestimate

What Retirees Actually Spend: The 70% Rule Falls Short

The 70% income replacement guideline suggests that a household earning $90,000 before retirement needs only $63,000 per year in retirement. The logic relies on the assumption that several large expense categories disappear or shrink dramatically: payroll taxes end, work-related costs disappear, the mortgage is paid off, and children are financially independent. Bureau of Labor Statistics Consumer Expenditure Survey data tells a different story. Households aged 65 to 74 spend approximately 83% of what households aged 55 to 64 spend - meaningfully higher than the 70% rule predicts. And for those in the early, active phase of retirement - the decade from 65 to 75 - spending is often at or near pre-retirement levels. The reasons are predictable in retrospect. Retirees stop commuting but start traveling. They stop buying work clothes but start spending on hobbies, grandchildren, and leisure activities. They have more time, which in many categories translates directly to more spending. Early retirement years are often the most active - the years you finally have time to take the trips, pursue the interests, and enjoy the lifestyle that working years delayed. Fidelity's Q4 2025 data showed an average 401(k) balance of $146,400. At a 4% withdrawal rate, that $146,400 generates $5,856 per year. Combined with an average Social Security benefit - roughly $20,000 to $24,000 per year for the average worker - the total retirement income for a median household is closer to $26,000 to $30,000 per year. That is a very different number from the 70% of $60,000-$70,000 in pre-retirement earnings that the rule suggests they need.

The Spending Categories That Surprise Retirees

The most common surprise in retirement spending is not a single large category - it is the cumulative weight of several categories that either do not shrink as expected or grow faster than expected. Housing is often assumed to disappear or shrink dramatically in retirement. In practice, for homeowners who own their home free and clear, the mortgage payment is gone - but property taxes, homeowner's insurance, maintenance, repairs, and eventual updates or modifications for aging-in-place do not disappear. Annual home maintenance typically runs 1-2% of home value. For a $350,000 home, that is $3,500 to $7,000 per year - indefinitely. Add property taxes of $3,000 to $6,000 per year depending on location, and housing costs for a paid-off home can still reach $8,000 to $15,000 annually. Healthcare is the most predictable surprise. Medicare covers a substantial portion of medical costs, but Part B premiums, Part D premiums, Medigap or Medicare Advantage plans, and routine out-of-pocket costs combine to $5,000 to $10,000 per year for a typical retiree. This figure grows with age and healthcare inflation. Family support is the most commonly overlooked budget item. Many retirees continue to provide meaningful financial support to adult children - help with down payments, grandchildren's education, family emergencies. Survey data consistently shows that retirees underestimate how much they will give to family members, and overestimate how financially self-sufficient their adult children will be. Leisure and travel peak in the early retirement years when health and energy are best. A retiree who budgets nothing for travel because they 'never traveled before' may find that available time completely changes their behavior and spending patterns.

The Spending Smile: How Retirement Expenses Evolve Over Time

Retirement spending does not move in a straight line. Research from financial planning academics and the Employee Benefit Research Institute documents a pattern sometimes called the 'retirement spending smile' - spending is relatively high in early retirement, dips in the middle years, and then rises again at the end as healthcare and long-term care costs escalate. The early years (ages 65 to 75) are often called the 'go-go' years - active, higher-spending, with travel, entertainment, and lifestyle expenditures at their peak. The middle years (ages 75 to 85) are the 'slow-go' years - somewhat less active, with spending dipping in leisure categories but healthcare costs beginning to rise. The final years (ages 85 and beyond) are the 'no-go' years - dramatically reduced discretionary spending, but potentially very high healthcare and long-term care costs. The smile shape means a retirement income plan built around a flat 3% or 4% annual withdrawal may not reflect the actual spending pattern. In the early years, a retiree may need to spend 5% or more of their portfolio to fund the lifestyle they planned for. In the middle years, 3% may be sufficient. In the final years, long-term care could require spending 10-15% of remaining assets per year. Planning for this shape - rather than a straight line - requires flexibility in the income structure. A rigid fixed withdrawal plan does not adapt well to the spending smile. A combination of guaranteed income for baseline expenses and a flexible portfolio for discretionary spending is better suited to the variable pattern of actual retirement costs. Long-term care costs represent the most extreme version of the final spike. Fidelity's $345,000 lifetime healthcare estimate excludes long-term care entirely. Adding even one year of assisted living at $60,000 and one year of nursing home care at $100,000 for one spouse adds $160,000 to the lifetime healthcare tab.

Building a Realistic Retirement Budget Before You Retire

The most effective antidote to retirement spending surprises is building a detailed, realistic budget before you retire - using actual categories and real cost estimates, not percentage rules. Start with non-negotiable expenses: housing costs (taxes, insurance, maintenance, whether or not a mortgage remains), healthcare (Medicare premiums, Medigap, prescriptions, out-of-pocket), food and transportation, and any debt payments that will continue into retirement. Layer in expected discretionary spending: travel, hobbies, entertainment, eating out, gifts to children and grandchildren. Be honest about what you actually spend in these categories now, and realistic about how much will change. Separate out irregular expenses: home repairs, car replacement, helping adult children, unexpected medical costs. These are real and recurring, even if irregular. A one-time replacement of an HVAC system at $8,000, a car purchase at $30,000, and a dental crown at $3,000 could all occur in the same year without any of them being unusual. Finally, include a placeholder for long-term care - even if you have not decided how to fund it. Acknowledging the potential cost, rather than omitting it from the plan, is the first step toward addressing it. A realistic bottom-up budget almost always produces a higher number than the 70% rule. That is not a reason for alarm - it is useful information. It tells you what you actually need to save and what income sources you need to build, rather than what a rule of thumb assumes.
