Why Running Out of Money Is a Real Risk
Since pension freedoms were introduced in 2015, millions of UK retirees have chosen flexi-access drawdown over traditional annuities. Drawdown offers flexibility and control, but it comes with a significant risk: your pension pot can run out while you are still alive.
Research from the Financial Conduct Authority (FCA) shows that many people in drawdown are withdrawing at unsustainable rates. Some are taking 8% or more per year from their pension, which could see their pot depleted within 15 years. With average life expectancy continuing to rise, the risk of outliving your money is very real.
The good news is that with careful planning, you can dramatically reduce this risk. This guide walks you through the key strategies used by financial planners to help retirees maintain a secure income throughout their lives.
How Long Does Your Pension Need to Last?
The first step in avoiding a pension shortfall is understanding how long your retirement could be. This depends on when you retire and your expected lifespan. Here are some rough planning horizons:
| Retirement Age | Planning Horizon | State Pension Starts | Years Without State Pension |
|---|---|---|---|
| 55 | 40+ years | 67 | 12 years |
| 57 | 38+ years | 67 | 10 years |
| 60 | 35+ years | 67 | 7 years |
| 65 | 30+ years | 67 | 2 years |
| 67 | 28+ years | 67 | 0 years |
Strategy 1: Set a Sustainable Withdrawal Rate
Your withdrawal rate is the percentage of your pension pot that you take as income each year. It is the single most important factor in determining whether your money will last.
The famous 4% rule suggests withdrawing 4% in year one, then adjusting for inflation each year. However, research suggests that for UK investors, a rate of 3-3.5% may be more appropriate, particularly if you are retiring early.
Withdrawal Rate Guidelines
| Withdrawal Rate | Risk Level | Best For |
|---|---|---|
| 2.5 - 3% | Very conservative | Early retirees (55-60), those wanting to preserve capital |
| 3 - 3.5% | Conservative | Most retirees without other guaranteed income |
| 3.5 - 4% | Moderate | Those with State Pension or other guaranteed income |
| 4 - 5% | Higher risk | Those with substantial other assets or shorter time horizons |
| 5%+ | Unsustainable | Likely to deplete the pot within 20 years |
Strategy 2: Build a Cash Buffer
One of the most effective ways to protect your pension pot is to maintain a cash buffer of one to two years of income. This serves two purposes:
- Avoids selling in a downturn — if markets fall 20-30%, you can draw from your cash buffer instead of selling investments at depressed prices
- Provides peace of mind — knowing you have immediate access to one or two years of income reduces anxiety about short-term market movements
- Smooths income — you can take regular monthly payments from your cash buffer while topping it up from investments at opportune times
Strategy 3: Understand Sequence of Returns Risk
Sequence of returns risk is the danger that poor investment returns in the early years of your retirement permanently damage your pension pot. This is one of the biggest threats to drawdown sustainability and is often misunderstood.
Consider two retirees who both achieve an average annual return of 7% over 20 years. One experiences strong returns in the first five years, while the other experiences poor returns in the first five years. Despite having the same average return, the retiree who suffered early losses will run out of money years sooner, because they were selling investments at low prices to fund withdrawals.
How to Mitigate Sequence Risk
- Reduce equity exposure in early retirement — consider a more conservative asset allocation in the first five to ten years of retirement, gradually increasing equities as you age (the "rising equity glide path")
- Use a bucket strategy — separate your pension into short-term (cash), medium-term (bonds), and long-term (equities) buckets
- Be flexible with withdrawals — reduce your withdrawals by 10-15% in years when your portfolio drops significantly
- Consider partial annuitisation — securing some guaranteed income reduces your dependence on investment returns in any given year
Strategy 4: Secure Guaranteed Income for Essentials
The most reliable way to avoid running out of money is to ensure your essential expenses are covered by guaranteed income. Guaranteed income sources in the UK include:
- State Pension — approximately £11,500 per year (2025/26), protected by the triple lock
- Defined benefit pensions — if you have a final salary or career average pension, this provides guaranteed income for life
- Annuities — you can use part of your defined contribution pension to purchase a guaranteed income for life
The Floor-and-Upside Approach
Many financial planners recommend what is known as the "floor-and-upside" approach. Calculate your essential living costs (housing, food, utilities, insurance) and ensure these are covered entirely by guaranteed income. Then use your drawdown pension for discretionary spending (holidays, hobbies, gifts).
| Income Source | Annual Amount | Type |
|---|---|---|
| State Pension | £11,500 | Guaranteed, inflation-linked |
| DB pension | £6,000 | Guaranteed (may be inflation-linked) |
| Annuity purchase | £4,000 | Guaranteed for life |
| Total guaranteed | £21,500 | Covers essential expenses |
| Drawdown pension | £8,000 - £12,000 | Variable, depends on investment returns |
| Total income | £29,500 - £33,500 | Comfortable retirement |
Strategy 5: Keep Investment Fees Low
Investment fees might seem small, but they compound dramatically over a 30-year retirement. The difference between paying 0.5% and 1.5% in total fees can be tens of thousands of pounds over the course of your retirement.
Every pound paid in fees is a pound that is not working for you. High fees effectively reduce your sustainable withdrawal rate. If your investments return 6% but you pay 1.5% in fees, your effective return is only 4.5%. Compare this with a low-cost portfolio returning 6% with 0.4% in fees, giving an effective return of 5.6%.
Strategy 6: Review and Adjust Annually
Retirement income planning is not a set-and-forget exercise. You should review your pension at least once a year and consider:
- Your remaining pot value — has it grown or shrunk? Recalculate your withdrawal rate based on the current value
- Your spending needs — have your expenses changed? Most people spend more in early retirement and less later
- Your investment mix — is your asset allocation still appropriate for your age and circumstances?
- Tax efficiency — are you making the most of your personal allowance and basic rate band?
- State Pension timing — as State Pension age approaches, you can reduce drawdown withdrawals
The Guardrails Approach
A practical method for annual adjustments is the "guardrails" approach. Set an initial withdrawal rate (say 3.5%) and define upper and lower guardrails. If your portfolio performs well and your withdrawal rate drops below 3%, increase your spending. If poor returns push your effective rate above 5%, cut back. This approach balances enjoyment of retirement with long-term security.
Strategy 7: Plan for Care Costs
Long-term care costs are one of the biggest unknowns in retirement planning. According to Age UK, the average cost of a residential care home in the UK is around £35,000-£40,000 per year, and nursing care can exceed £50,000 per year.
While not everyone will need residential care, it is wise to have a contingency plan. Options include:
- Keep some pension invested — do not draw down your entire pot. Having a reserve for potential care needs provides a safety net
- Consider an immediate needs annuity — if care is needed, these annuities convert a lump sum into a guaranteed income to cover care fees
- Understand the means test — local authorities assess your assets to determine whether you must self-fund care. In England, the upper capital limit is £23,250 (your pension pot counts if you are already drawing from it)
Putting It All Together: A Retirement Income Checklist
- Calculate your essential and discretionary spending needs
- Map out your guaranteed income sources (State Pension, DB pension, annuity)
- Determine the gap that your drawdown pension needs to fill
- Set an appropriate withdrawal rate (typically 3-4% for most retirees)
- Build a cash buffer of one to two years of income
- Choose a low-cost drawdown provider to minimise fees
- Invest appropriately for your risk tolerance and time horizon
- Review your plan annually and adjust as needed
- Consider professional advice for cashflow modelling and ongoing guidance
