Retirement Spending & Cash Flow Planner
Retirement spending typically does not stay flat. Research suggests it tends to follow a U-shape — higher in the active early years, lower in the middle years, then partially rising again with healthcare costs. This tool illustrates how phased spending assumptions may change long-term cash flow needs compared to the conventional flat-spending model.

Three Spending Phases
Adjust the spending multiplier and ending age for each phase. Defaults reflect commonly cited patterns from retirement spending research (Blanchett, Bernicke). Healthcare costs are modeled separately and rise faster than general inflation in later years.

Flat vs. Phased Spending Comparison
How using a phased spending assumption may change the long-term picture compared to assuming spending stays constant. Both scenarios use identical inputs, returns, and inflation — the only difference is the spending pattern.

Based on the figures entered, the phased spending model suggests the portfolio may last meaningfully longer than the flat-spending assumption indicates. The conventional flat-spending model is conservative — it may overstate retirement income needs and understate sustainability.

What the Research Suggests
The phased-spending pattern is supported by multiple academic and industry studies. Key findings worth knowing:
Spending tends to decline in real terms after age 75
Studies of actual retiree spending (Blanchett, JFP 2014; Bureau of Labor Statistics Consumer Expenditure Survey) consistently show real (inflation-adjusted) spending declines roughly 1% per year from age 65 to 85. This is sometimes called the "retirement spending smile" because of the late-life rebound from healthcare.
Healthcare costs work in the opposite direction
While discretionary spending declines, healthcare costs typically rise faster than general inflation — often 4–6% per year versus 2–3% for general CPI. By the late 80s, healthcare can represent 15–25% of total spending, creating the upturn at the end of the curve.
Long-term care is the wildcard
The phased model assumes typical spending patterns. Roughly 70% of people 65+ will need some form of long-term care in their lifetime; about 20% will need it for 5+ years. Care costs can range from $50K–$150K+ per year. This risk is not captured in the figures above and is often the largest single financial risk in retirement.
The flat-spending assumption may overstate needs
Conventional retirement calculators assume spending stays constant in real terms for 30 years. This is conservative — it may suggest that retirees need 10–25% more in savings than actual spending patterns require. The risk: working longer or saving more than necessary based on overly conservative assumptions.
Important Considerations
Important Assumptions
This illustration uses a simplified deterministic model. The phased spending pattern reflects average tendencies observed in retiree spending research, but individual spending patterns vary substantially. The tool assumes: constant portfolio returns at the entered rate (real markets vary), general inflation applied uniformly to baseline spending, healthcare cost inflation applied separately to the healthcare line, no taxes on portfolio withdrawals, no Required Minimum Distributions modeling, no Social Security earnings test or claiming timing optimization, no long-term care events, no major one-time expenses (home renovations, gifts to family, vehicle purchases), and no sequence-of-returns risk beyond the entered constant return. Annual guaranteed income is inflation-adjusted at the general rate. Spending phase multipliers are applied to the inflation-adjusted baseline at the start of each phase.
Want to discuss how these spending patterns may apply to your plan?
The phased spending model can be a useful counterweight to overly conservative flat-spending assumptions — but real plans require accounting for individual spending patterns, healthcare planning, long-term care risk, tax considerations, and sequence-of-returns risk. A BlueLine Advisors consultation can help you review how spending assumptions may interact with the rest of your retirement plan.
