Why behaviour matters as much as the numbers in retirement planning

Retirement planning often focuses on the technical details: tax, investment returns and withdrawal rates. But, in reality, many of the biggest risks in retirement come from how people behave, especially during periods of uncertainty.

Understanding this behaviour is an important part of helping clients achieve good outcomes.

How loss aversion affects retirees

Many clients cope well with market ups and downs while they're working. Once they retire and start taking income, their reaction can change.

Market falls can feel more serious when money is being withdrawn. Losses no longer feel temporary. This is known as loss aversion: the tendency to feel losses more strongly than gains. 

In retirement, this can lead to decisions such as panic withdrawals, selling investments at the wrong time, or moving too much money into cash. Over time, these actions can reduce the chances of savings lasting as long as planned.

The risk of underspending

Behavioural bias doesn’t always lead to taking too much risk. In many cases, it leads to the opposite.

Some retirees become very cautious. They delay spending, put off holidays and worry about running out of money, even when their plan shows they can afford to spend more. 

Helping clients feel confident enough to enjoy their retirement, while still feeling secure about the future, is a key part of the adviser’s role.

Letting go of old assumptions

Clients often base decisions on past experiences. This might include how they spent money during their working lives, memories of previous market shocks, or how their parents handled finances.

These reference points don’t always fit today’s reality. Retirements are longer. Tax rules are different. Family needs have changed. 

Advisers add value by helping clients update these assumptions and make decisions based on their current situation, not the past.

Family dynamics play a role

Money decisions in retirement are rarely just about one person.

Often, one partner takes responsibility for finances, which can leave the other exposed later on. Adult children may only get involved during stressful moments. Difficult conversations about planning are sometimes avoided altogether. 

Early discussions, clear records and involving the right people at the right time can help reduce future problems and support better outcomes for everyone involved.

Supporting clients through uncertainty

Advisers are not just there to build plans. They help clients stay on track when markets are volatile or life changes.

By combining technical knowledge with an understanding of human behaviour, advisers can help clients make steady, informed decisions over time. 

In retirement, that support can make a meaningful difference, helping clients feel more confident about their income today and their future tomorrow.
