How to Create a Retirement Income Plan

For most of your working life, the plan is simple, even if it isn't always easy: save as much as you sensibly can, keep contributing to a pension, and let time and compound growth do most of the heavy lifting. As retirement gets closer, that plan has to change shape entirely. You stop being an accumulator of assets and start being the manager of an income — drawing money from various pots, in a sensible order, to replace the salary you're no longer earning. This shift catches a lot of people off guard, because very little in mainstream financial education covers "how to turn savings into an income" in the way it covers "how to save." This guide walks through a straightforward, step-by-step framework for building your own retirement income plan: listing every source of money you'll have coming in, working out what you actually need to spend, finding the gap or the surplus between the two, and deciding how to structure withdrawals so your money lasts as long as you need it to.

From saving to spending: a change in mindset

The single biggest adjustment in retirement planning isn't a spreadsheet or a formula — it's psychological. Throughout your career, more saved is simply better, and a rising account balance is reassuring feedback that you're doing the right thing. In retirement, that same feedback loop flips. Your pension pots are designed to be drawn down, and a falling balance is not a sign that something has gone wrong; it's the plan working as intended, provided the fall is happening at a sustainable pace. Many retirees find this genuinely uncomfortable, and it's one of the most common reasons people either underspend out of anxiety (missing out on the retirement they worked for) or fail to plan properly at all because thinking about "spending down" feels unfamiliar and even a little frightening.

A good income plan removes much of that anxiety, because it replaces a vague worry ("will my money last?") with a specific, reviewable answer ("here is where my income comes from this year, here is what I expect to spend, and here is when I'll next check whether that's still on track"). It also forces you to confront two risks that don't really exist in the same way during your working life: longevity risk (not knowing how long your money needs to last, because none of us know our own life expectancy in advance) and sequencing risk (the danger that poor investment returns in the early years of retirement can do outsized, lasting damage to a portfolio you're also withdrawing from). Both are covered in more depth elsewhere in this section, but they're worth holding in mind as the backdrop to every step below.

Step 1: list every source of income

Before you can plan anything, you need a complete picture of what's coming in. It's surprisingly common for people to forget a small workplace pension from a job they left a decade ago, or to underestimate how much their state pension will actually pay. Start by listing, for both yourself and any partner:

State pension. Check your forecast on the government's website to see your projected weekly amount and the date you can claim it. The full new State Pension is currently £230.25 a week (2025/26), though your own entitlement depends on your National Insurance record and may be higher or lower.

Workplace and personal pensions. This includes any defined benefit (final salary) pensions, which pay a guaranteed income for life, and defined contribution pensions, which build up a pot you'll need to convert into income yourself, whether through drawdown, an annuity, or a mixture of both. Track down every scheme you've ever paid into — the government's pension tracing service can help if you've lost contact with an old provider.

Other savings and investments. ISAs, general investment accounts, savings bonds, and any other capital that isn't held in a pension wrapper all count as potential income sources, and can be especially useful for topping up spending in the early, more tax-efficient years before other pensions are drawn.

Rental or part-time income. Many people ease into retirement gradually rather than stopping work on a single date. Rental income from a second property, consultancy work, or a part-time role can all reduce how much you need to draw from your pensions, particularly in the first few years.

Step 2: separate essential spending from discretionary spending

Once you know what's coming in, the next step is understanding what's likely to go out — and this is where splitting your spending into two categories makes a real difference. Essential spending covers the things you need regardless of how markets are performing: housing costs, utility bills, council tax, food, insurance, and any regular medical or care costs. Discretionary spending covers everything that adds richness to retirement but could, if needed, be scaled back for a year or two without real hardship: holidays, eating out, hobbies, gifts to family, and larger one-off purchases.

Going through several months of bank statements is the most reliable way to build this picture, rather than guessing. Many people are surprised by how much of their current spending is genuinely discretionary once they look closely, which is often good news — it means there's more flexibility built into the household budget than they realised, and more room to absorb a bad year for investment returns without derailing the overall plan.

Step 3: work out the gap — or the surplus

With your income sources and your spending both mapped out, you can compare the two. Guaranteed, inflation-linked income — typically state pension, plus any defined benefit pension or annuity income — is compared against essential spending first. If guaranteed income comfortably covers essential spending, you're in a strong position: any shortfall in discretionary spending can be met flexibly from drawdown or savings, and a poor year for investment returns simply means dialling back discretionary spending rather than threatening your ability to pay the bills.

If guaranteed income falls short of essential spending — which is common for anyone retiring before state pension age, or anyone without a defined benefit pension — the shortfall (the "gap") needs to be filled from your other pots in a way that's sustainable over the long term. This is precisely where a considered withdrawal strategy earns its keep, rather than simply drawing whatever feels comfortable in any given year.

In this simplified example, a couple's guaranteed income already covers their essential spending with a small margin to spare, leaving a gap of roughly £6,100 a year in discretionary spending to be funded from their remaining defined contribution pots via drawdown. Because that gap sits entirely within discretionary spending rather than essential costs, it can be flexed down in a poor investment year without any real hardship — which is exactly the kind of resilience a well-structured plan aims to build in.

Step 4: decide how to structure your withdrawals

With the gap identified, the final step is deciding how to draw the money sustainably. A commonly discussed starting point is an initial withdrawal rate somewhere in the region of 3% to 4% of an invested portfolio's value, adjusted for inflation each year — though this figure is heavily caveated, was originally derived from historical US market data, and should never be treated as a guarantee. Your own sustainable rate depends on your investment mix, how long you need the money to last, whether you want to preserve capital for inheritance, and your appetite to flex spending in poor years.

Other practical questions to settle at this stage include which pot to draw from first (tax-efficient ordering can matter a great deal — for example, drawing taxable income up to your personal allowance before touching tax-free ISA savings), whether to take your tax-free pension lump sum in one go or in stages, and how to sequence state pension against private pension withdrawals if you're retiring before state pension age. That last question is explored in detail in our guide on state pension versus drawdown sequencing, which walks through both the case for deferring your claim and the case for taking it as soon as you're eligible, with a worked side-by-side comparison of each approach.

It's also worth thinking about withdrawals in terms of risk, not just tax. Drawing a large chunk of a pension pot shortly after a sharp market fall can lock in losses in a way that's very difficult to recover from later, a phenomenon known as sequencing risk. Some retirees manage this by holding a cash buffer covering a year or two of essential spending, so they're never forced to sell investments at a low point purely to fund day-to-day living costs — an approach explored fully in our guide to the bucket strategy.

Matching guaranteed income to essential spending

One of the most valuable principles in retirement income planning is trying, where practical, to match your essential spending with guaranteed income sources, and reserving flexible drawdown for the discretionary layer on top. This might mean deferring your state pension for a period to increase the guaranteed amount, using part of a pension pot to buy an annuity that covers a specific fixed cost, or simply recognising that a defined benefit pension you already hold does most of this job for you. The logic is simple: guaranteed income can't run out and doesn't fall when markets do, so the more of your non-negotiable costs it covers, the less your peace of mind depends on investment performance.

A simple five-point check before you finalise your plan

Reviewing and adjusting your plan over time

A retirement income plan is not a document you write once and file away. Investment markets move, inflation erodes purchasing power at different rates in different years, your own spending needs shift as you move through the different phases of retirement, and rules around tax and pensions themselves are periodically reformed by government. For all these reasons, treat your plan as a living framework that deserves a proper review at least once a year, and after any significant life event such as the death of a partner, a health diagnosis, or a large unplanned expense.

A useful annual review checks three things in turn: whether your actual spending over the past twelve months matched what you budgeted for, whether your portfolio's value and recent investment returns still support your planned withdrawal rate, and whether any of your income sources are due to change soon — for example, a fixed-term annuity ending, a state pension deferral period completing, or a mortgage being paid off. Catching a mismatch early, while it's still a small adjustment, is far easier on both your finances and your peace of mind than discovering a much bigger problem several years down the line.

It's also worth revisiting your plan whenever the broader rules change. Pension tax allowances, state pension ages, and the thresholds used to calculate benefits have all shifted over the years, and a plan built around today's figures may need recalibrating as those goalposts move. Building a habit of an annual check-in, even a simple one done with a cup of tea and last year's bank statements, does far more to keep a retirement income plan on track than any one-off calculation ever could.

When to get professional cashflow-modelling advice

The framework above works well for relatively straightforward situations, but some circumstances genuinely benefit from professional advice and dedicated cashflow-modelling software, which can project your income and spending year by year under different market conditions. Consider seeking regulated financial advice if you have multiple pensions of different types (particularly if any include valuable guarantees worth understanding before you touch them), if you're weighing up deferring your state pension or a defined benefit pension against taking it immediately, if you're a higher earner concerned about tax efficiency across several income sources, or if your spending needs are likely to change substantially over time — for example, funding care costs later in retirement.

A cashflow model can stress-test your plan against a run of poor investment returns, a long life expectancy, or an unexpected large expense, showing you not just whether your plan works on average, but how much resilience it has if things don't go entirely to plan. For anyone with a reasonably complex set of pensions and savings, the cost of an hour or two of professional advice is frequently repaid many times over in the confidence — and often the tax savings — it provides.
