When Can I Retire?

Retirement is often framed as a financial milestone defined by a number. Accumulate a sufficiently large pension, reach a target figure, and the decision appears straightforward. In practice, the calculation is rarely that simple. Capital size is only one variable. The more relevant question is whether those assets can generate reliable income, withstand volatility and support the level of expenditure required over time ^[1].

As Jack Munday, Chartered Financial Planner & Partner at Saltus, explains, “retirement for one person is completely different to retirement for another.” For some, it represents a full stop. For others, it is a gradual transition or a change in pace. Without clarity on what retirement actually looks like in practice, financial modelling has little direction.

Start With Defined Objectives

A common mistake is to begin with the pension pot rather than the outcome the plan is intended to support. Retirement planning is not about reaching a universal figure; it is about defining a sustainable standard of living and understanding what level of capital is required to maintain it ^[2].

“It’s about reaching a quality of life and reaching your objectives,” Jack says. The required level of wealth will vary significantly depending on expenditure expectations, family commitments and how long those assets need to last.

Before considering timing, individuals need clarity on several factors:

• Whether work will stop entirely or reduce gradually
• What level of discretionary spending is expected
• How travel, leisure and lifestyle priorities might evolve
• Whether financial support for children or other family members will continue

Only once these questions are answered does the financial analysis become meaningful.

Liquidity and the Transition From Earnings

One of the most overlooked elements of retirement readiness is liquidity.

During the accumulation phase, the emphasis is naturally on keeping money invested and compounding. As retirement approaches, however, the sequencing of withdrawals becomes increasingly important. A defined cash reserve provides flexibility during periods of market volatility and reduces the risk of selling investments at unfavourable moments.

Jack highlights the value of “a comfortable runway of cash” alongside “a good emergency fund.” The rationale is not purely technical. Retirement often removes what he describes as “your biggest asset and that is your earning ability.” Even when financial resources are sufficient, the shift from earning to withdrawing can alter behaviour. Liquidity helps stabilise that transition while longer-term assets remain invested.

Structuring Expenditure Realistically

Detailed line-by-line budgeting is rarely necessary. A simpler framework can provide clarity without unnecessary complexity.

Jack suggests thinking about spending in three broad layers:

• Cost of existence
  Essential expenditure required to maintain stability: housing, utilities, food and core financial commitments.
• Cost of living
  Discretionary spending that shapes everyday lifestyle hobbies, travel, socialising and memberships.
• Nice-to-haves
  Larger, less frequent expenses such as “big bucket list holidays” or “replacing the car every three or four years.”

This structure helps establish realistic spending parameters while recognising that expenditure in retirement rarely follows a straight line. Early years are often more active and therefore more expensive, followed by a quieter middle period and potentially higher costs later in life as health or care needs increase ^[3].

Asset Location and Tax Efficiency

Accumulating wealth tax-efficiently is not the same as drawing it tax-efficiently.

A common issue arises where the majority of assets sit inside a single pension wrapper. While beneficial during accumulation, concentration can limit flexibility when income is required. As Jack notes, “when it comes to taking it out, you’ve only got one basic rate allowance. You’ve only got one pot then to draw from.”

A diversified structure, combining pensions, ISAs, general investment accounts and cash, provides more flexibility when generating retirement income ^[4]. For couples, the opportunity is even greater. Using both partners’ tax allowances can materially improve long-term outcomes. Even relatively modest pension contributions for a non-working spouse can add meaningful flexibility in later years.

In this sense, retirement outcomes are influenced not only by how much has been accumulated, but by how those assets are distributed across different structures.

Possible Versus Sustainable

Another important distinction is the difference between retirement being possible and retirement being sustainable.

For some individuals, sustainability means preserving capital indefinitely. For others, the objective is to front-load experiences in the early years. Jack describes clients who prioritise those initial years: “I want to ensure that my primary objective is these first 15 years I can travel, enjoy it, spend it, and spoil the family.”

Neither approach is inherently right or wrong. The key question is whether the plan remains viable under less favourable conditions. This is where modelling becomes particularly useful. Stress testing assumptions around market returns, longevity and inflation can reveal whether a strategy holds together over time ^[5].

Behavioural Pressures and Trade-Offs

Retirement decisions are rarely purely mathematical. Behaviour and expectations often shape the outcome just as much as financial modelling.

One common misconception is the need to replicate pre-retirement income. In reality, savings contributions typically stop. As Jack points out, “that £1,500 a month that you’re saving for a rainy day, well, the rainy days come, that was your retirement.” Recognising this shift can materially change how affordable retirement appears.

Trade-offs also emerge around intergenerational planning. Supporting children or family members during lifetime may reduce the capital available later. Balancing those priorities requires clarity. As Jack often reminds clients, “you’ve got to be selfish to be kind” — ensuring personal financial security before committing resources elsewhere.

Open communication plays an important role here. Where retirement planning involves a couple or wider family, alignment around objectives and expectations becomes essential. As Jack puts it simply, “The more you can tell me, the more I can help you.”

Retirement as a Planning Discipline

Retirement is not a single decision made once a particular number has been reached. It is the result of aligning expenditure, asset structure, tax efficiency and risk tolerance within a framework that can withstand uncertainty ^[6].

Capital matters, but on its own it provides limited guidance. A sustainable retirement depends on how assets are structured, how withdrawals are sequenced and how realistic the underlying assumptions prove to be over time.

The question is not simply whether you have accumulated enough. It is whether what you have accumulated can support the life you intend to lead, for as long as that life requires funding.
