When plans need to change

A retirement plan is not a document that is followed. It is a set of assumptions that will be wrong in ways that require response.

The monitoring measure

One number does most of the work.

Divide current annual withdrawals by the current portfolio value. That is the current withdrawal rate.

Compare it to where it started. If the plan began at four per cent and the rate has drifted to five and a half, the plan is under pressure.

If it has drifted down to three, there is capacity for more spending.

Checking this annually, and acting on meaningful drift, is most of what ongoing management requires.

The triggers for a full review

A large market movement in either direction, particularly in the first decade.

A health change affecting either life expectancy or expected care needs.

The death of a spouse, which changes income, tax filing status and everything downstream of both.

A change in housing, which alters both the asset position and the cost base.

A significant change in tax law, which affects conversion and withdrawal strategy.

Spending that has drifted substantially from what was planned, in either direction.

A family obligation — supporting an adult child, a grandchild's education, a parent's care.

This last is one of the most common sources of unplanned expenditure and it is rarely modelled in advance.

The adjustments available

In rough order of how easy they are.

Reduce discretionary spending. The first lever and the most effective if applied early.

Defer large expenditures. A vehicle, a trip, a renovation.

Delay Social Security if not yet claimed, which permanently increases guaranteed income.

Take part-time work, which reduces withdrawals during the period of highest sensitivity.

Reduce fixed costs, which requires larger changes — moving, downsizing, changing insurance arrangements.

Access home equity, through downsizing or a facility.

Reduce essential spending, which is the least pleasant and is available.

Having thought about the order in advance means the response to a bad period is a plan rather than a panic.

The asymmetry of timing

The point that matters most.

A small adjustment made early is much less painful than a large one made late.

Reducing spending by five per cent in the second year of a decline is barely noticeable. Reducing it by thirty per cent in year eight because the portfolio has been depleted is a different experience entirely.

Which means the value of annual monitoring is not information for its own sake. It is the ability to make small corrections while they are still small.

The upward adjustment

Which people are much worse at.

Where markets have done well and the withdrawal rate has fallen substantially below plan, the correct response is to spend more.

Retirees consistently fail to do this, and the result is dying with a large unspent balance while having foregone the early active years when the spending would have been most valuable.

A guardrail framework that permits increases as well as decreases addresses this, largely by giving explicit permission.

The annual routine

An hour or two, once a year.

What was spent, against plan. Current portfolio value and the resulting withdrawal rate. Whether the allocation has drifted. What the tax position looks like and whether there is bracket room to use. Whether any assumption has changed materially.

Then a decision: continue, adjust down, or adjust up.

That is the whole process, and doing it consistently matters far more than doing it sophisticatedly.

What not to change

The strategic elements should be stable.

Changing the asset allocation after a decline, abandoning a conversion strategy because of one bad year, or reversing a Social Security decision on the basis of a headline are reactions rather than adjustments.

The distinction is whether the change responds to a durable shift in circumstances or to a recent experience.

Who else needs to know

A practical addition to the annual review.

Where a plan changes materially, the people affected should be told — a spouse, obviously, and where relevant adult children who may have expectations.

This applies particularly where a decision has been made to spend more, to help family less, or to fund care from assets that had been assumed to pass on.

Communicating a change of intention at the time is considerably easier than leaving it to be discovered.
