Spending Falls Through Retirement, Then Rises at the End
Most retirement models assume constant spending in real terms for thirty years. Actual household spending does not behave that way: it is highest in the first decade, falls through the second and third as travel and activity reduce, and can rise sharply at the end if care is needed. Planning to a flat line is conservative in the middle and optimistic at the end.
- The answer: Spending is highest in the active early years, declines through the middle decades, and can rise steeply at the end where care is needed.
- The trap: The late rise is the one that breaks plans, because it is large, uncertain in timing, and arrives when the portfolio is smallest.
- The recommendation: Front-load discretionary spending into the years you can use it, and keep a reserve against the late costs rather than assuming a flat line covers both.
Where the AI summary above gets this wrong
"You should plan for your retirement spending to stay the same in real terms for thirty years."
That's surface-true. Here's what it misses:
- Observed spending falls through the middle decades — Travel, dining and activity spending reduce as households move from active to less active years, which is why a flat assumption overstates the middle of a retirement.
- The late rise is real and is not in the flat assumption either — Aged care and health costs can rise steeply in the final years, and a flat line neither anticipates that nor funds it.
01 The shape
The first decade of retirement is the most expensive discretionary period. Health is best, the household is most mobile, and the spending that was deferred during working years — travel, a caravan, time with grandchildren who live elsewhere — happens then.
The middle decades see that discretionary spending fall. Travel reduces, the second car goes, restaurant meals become less frequent. Essential spending stays roughly flat in real terms, so the total falls without any decision being made.
The final years can reverse it. Home care, and then residential care, are substantial costs, and health spending rises irrespective of care — the components are set out in the aged care costs reference.
02 Why the flat assumption is wrong twice
Against the middle decades it overstates. A household planning a flat real spend from 65 to 95 is funding a level of activity at 88 that most people do not have, and is therefore under-spending at 68 to pay for it.
Against the final years it understates. Aged care costs are not in the ordinary budget and the flat assumption does not create a reserve for them, so the plan meets them by depleting whatever is left.
The two errors do not cancel. They occur at different times, and the first one costs experiences at the age you can still have them while the second one costs security at the age you cannot recover from it.
Shows: the total spending across a retirement under a declining profile against a flat one, using the reduction and the late care cost you supply. Ignores: inflation, the Age Pension, investment returns, and the uncertainty in when the late costs begin.
03 What to do about it
Plan the discretionary layer explicitly by decade rather than as a constant. A larger travel budget for the first ten years and a smaller one afterwards reflects how households actually behave and frees up spending at the age it is worth most.
Hold a separate reserve for the late costs rather than assuming the general balance covers them. For a homeowner, the home itself is frequently that reserve, which is one of the arguments for not spending it earlier.
And re-check the shape every few years. Health and circumstances change the timing, and the plan that assumed a decade of active years may be describing five or fifteen — which is a reason to revisit rather than to plan more conservatively.
The version of this that costs people the most is the couple who spend cautiously from 65 to 80 and then find they cannot use the money. The travel you defer at 68 is not available at 85. Front-load the discretionary layer deliberately, and keep the reserve for care separate so that the two decisions do not compete.
FAQ
How does my spending naturally fall as I move from active to slow-go to no-go years?
Discretionary spending — travel, dining, activities — falls through the middle decades while essential spending stays roughly flat in real terms. The total therefore declines without any decision, then can rise sharply if care is needed.
Should I spend more in my active years and less later?
The observed pattern suggests it, and a flat real assumption under-spends the first decade to fund a level of activity most households do not have at 88. The reservation is the late care cost, which needs its own provision.
How do I plan for the late rise in costs?
Hold a separate reserve rather than assuming the general balance covers it. For a homeowner the home is frequently that reserve, which is an argument for not spending it earlier.
