What to Do If You Cannot Save Enough for Retirement

When the required saving is larger than the available money, the answer is not a better investment. It is deciding which of the other four variables moves — and doing that deliberately rather than by default.

Kavita has run the numbers and does not like them

Kavita finally worked out what her retirement would cost and what she would need to save each month to fund it. The figure is roughly double what she can manage.

Her first instinct was to look for a better investment, which is the universal first instinct and almost always the wrong place to look. Her second was to stop thinking about it, which is more common still and considerably more expensive.

There is a third response, and it starts by recognising that the shortfall has five possible solutions rather than one.

The five variables

A retirement plan has five things in it, and if the numbers do not work then at least one of them has to move.

How much you save. The most obvious and usually the most constrained.

How long you save for. Working longer, which is the single most powerful variable available to somebody starting late.

What the money is invested in. The one everybody reaches for first and the one with the least room in it, since the honest range of expected returns is narrower than the marketing suggests.

How much you will spend in retirement. Treated as fixed and rarely is.

What else could fund it. Property, a business, other assets, or income continuing into retirement.

Kavita's shortfall does not have to be closed by one of these. It usually gets closed by small movements in three or four, which is far more achievable than a large movement in any single one.

Why the investment lever is the wrong first choice

Reaching for higher returns is intuitive — less money needs a better rate to reach the same place — and it fails for a specific reason.

Higher expected returns arrive with wider outcomes. For somebody with decades ahead that is a reasonable trade, since there is time for a bad stretch to recover. For somebody in Kavita's forties, with a shortfall she is trying to close, it introduces the possibility of arriving at sixty with less than the cautious plan would have produced, and no time to fix it.

There is a legitimate version: if she is sitting in cash or in something inappropriate for a fifteen-year horizon, moving to a sensible diversified allocation is a correction rather than a gamble, and it may be worth a great deal. What does not work is taking concentrated risk to make up a gap, which is how a shortfall becomes a catastrophe.

The variables that actually have room

Working longer does the most, and it is the one people refuse to consider until much later than they should. Each additional year adds contributions, removes a year of drawdown, and gives the corpus another year to grow — three effects at once, which is why it moves the arithmetic further than anything else on the list. Semi-retirement is the softer version, and it captures most of the benefit.

Spending less in retirement is treated as defeat and is frequently the most rational move available. A retirement costing less is easier to fund than one costing more, and deciding to live somewhere cheaper, or to carry no housing cost into retirement, can change the required corpus more than any investment decision Kavita could make. This deserves to be examined properly rather than dismissed, because the assumed retirement lifestyle in most plans is an assumption rather than a requirement.

Saving more has more room than it appears if the increases are attached to future income rather than to today's. Committing now that every future raise is split between saving and spending closes gaps that seem unclosable from today's salary, and it does not require her to live on less than she currently does.

Other assets deserve honest examination. A property that could be downsized, a second property, a business with a sale value. These are frequently excluded from the calculation because selling them is unwelcome, which is a reason to weigh them rather than a reason to ignore them.

What to do first, in order

Before any of the above, cover the catastrophic risks — health cover, and term life cover if anybody depends on her. A plan with a shortfall is fragile, and an uninsured medical event would end it entirely. This comes first even though it uses money that could have gone to the shortfall.

Then clear expensive debt, since that is a certain return at the interest rate and nothing in investing offers one.

Then increase saving to whatever is genuinely sustainable, and automate it, and commit the split for future raises.

Then have the conversation about spending and working longer, which is where the largest movements actually live, and which is a conversation rather than a calculation because it involves whoever shares her life.

And then recheck. A plan that was short by half rarely stays short by half once three variables have moved a little.

The part that is not arithmetic

There is a version of this that goes badly and it is worth naming: knowing the plan does not work and therefore not looking at it.

Kavita has already done the hardest thing by running the numbers. The shortfall was there whether or not she calculated it, and the calculation is what makes it addressable. A plan that is short and known is in far better condition than a plan that is short and unexamined, because only the first one can be adjusted.

It is also worth saying plainly that partial success counts. A retirement funded three-quarters of the way is enormously better than one funded a third of the way, and the framing where anything short of the full number is failure is what causes people to stop trying.

What to take away

When the required saving exceeds what is available, the answer is not a better investment. It is moving several of the five variables a little: save more from future raises, work longer or partially, spend less later, and count assets you had excluded.

Cover the catastrophic risks and clear expensive debt before chasing the gap. Do not take concentrated risk to close it, because the version where that fails leaves no time to recover. And treat a shortfall that has been measured as a problem in much better condition than one that has not.
