Why it’s important
You’ve worked hard, saved for decades, and built a pension pot. Now comes the tricky bit: how much can you safely take out each year without running out of money?
Get this wrong and you could either outlive your savings or live too cautiously and not enjoy your retirement.
The goal is balance — steady income, lasting capital, and flexibility for life’s surprises.
What you need to know
1️⃣ Retirement is a marathon, not a finish line
If you retire at 65, there’s roughly a one in four chance you’ll live into your 90s. That means your retirement money may need to last 25–30 years.
You don’t need a plan that works just for the next few years — you need one that works through market booms, crashes, inflation spikes, and good health or bad.
2️⃣ The “safe withdrawal rate” explained
A popular starting point is the 4% rule — withdrawing 4% of your pot in the first year of retirement, then increasing it each year with inflation.
It’s based on long-term market data and aims to make your money last around 30 years.
Example: a £500,000 pension pot → £20,000 in year one, rising each year with inflation.
But — it’s not a guarantee.
Low returns, higher inflation, or living longer can mean 4% is too high. Many UK planners now suggest 3–3.5% as a safer starting point, especially if you want high confidence your pot will last.
3️⃣ Sequence of returns risk
Here’s the danger most retirees overlook: it’s not just average returns that matter, but when they happen.
If markets fall early in retirement while you’re drawing income, your pot shrinks faster and has less chance to recover — even if long-term returns look fine.
Example:
Two retirees both earn 5% average annual returns.
- Retiree A hits strong markets early — pot lasts 30+ years.
- Retiree B retires into a crash — pot empties in 20.
The fix: keep 1–2 years’ worth of income in cash or bonds. When markets fall, draw from that buffer instead of selling shares at a loss.
4️⃣ Spend flexibly, not rigidly
The best withdrawal plans adjust to reality.
Instead of taking a fixed amount each year regardless of markets, use a “guardrail” approach:
- If your portfolio grows strongly, you can increase withdrawals a bit.
- If it falls sharply, trim spending temporarily.
That small flexibility can make your pot last years longer — without major lifestyle sacrifice.
5️⃣ Don’t forget inflation
Even mild inflation compounds over time.
At 3% inflation, £1,000 of monthly spending today will need £1,810 in 20 years.
That’s why it’s dangerous to park everything in cash — your “safe” money slowly loses purchasing power.
Keep a portion invested in assets that grow faster than inflation, like equities or diversified funds, so your income can keep pace with rising prices.
6️⃣ Layer your income sources
Your retirement income isn’t just your pension pot.
Combine:
- State Pension: inflation-linked and guaranteed — your base layer.
- Workplace or private pensions: flexible drawdown or annuity income.
- ISAs and savings: tax-free top-ups for one-off spending.
By blending these, you can withdraw from the most tax-efficient source each year and smooth your income.
7️⃣ Watch out for tax traps
Remember:
- The first 25% of your pension can usually be taken tax-free.
- The rest is taxed as income.
Withdrawing too much in one year could push you into a higher tax band.
Instead, draw gradually and use ISAs to supplement income tax-free.
It’s about keeping what you earn — not giving it back to the Treasury.
8️⃣ When to consider an annuity
If you crave stability or hate market risk, consider buying an annuity with part of your pension pot.
Rates have improved as interest rates have risen, and a lifetime annuity guarantees income for life — no matter how long you live or what markets do.
You can combine strategies:
- Use annuity income to cover essential bills.
- Keep the rest invested for flexibility and growth.
What you should do next
✅ Step 1: Work out your essential vs flexible spending
Write down what income you must have (bills, food, insurance) and what’s optional (holidays, leisure).
Cover essentials with guaranteed income (State Pension or annuity). Use investments to fund the fun stuff.
✅ Step 2: Set your initial withdrawal rate
Start around 3–4% of your pot. For example, if you have £300,000, begin with £9,000–£12,000 per year.
Adjust annually based on inflation and performance.
✅ Step 3: Keep 1–2 years’ income in cash or short-term bonds
This “rainy day” reserve stops you from selling investments after market dips.
✅ Step 4: Rebalance once a year
Sell a bit of what’s grown, top up what’s lagged. It keeps your risk steady and prevents your portfolio from drifting too aggressive.
✅ Step 5: Review your plan annually
Life changes. Markets move. Inflation bites.
Check in every year — are you on track? If not, tweak spending or adjust your mix.
✅ Step 6: Don’t panic during downturns
Market dips are normal. History shows patient investors recover. Your cash buffer is there for a reason — use it and wait for markets to heal.

Worked example
Ian, 66, retires with a £400,000 pension and £20,000 in ISAs.
He decides to withdraw 3.5% (£14,000) a year from his pension, topped up by £5,000 from ISAs for holidays.
He keeps £30,000 (about two years’ spending) in cash and bonds.
When markets fall 15%, he pauses ISA withdrawals and uses his cash buffer instead.
After two recovery years, his investments rebound and his pot remains steady at around £390,000 — even after withdrawals.
His spending stays comfortable, and his money keeps working for him.
Bottom line
Making your retirement money last isn’t about luck — it’s about discipline, flexibility, and structure.
1️⃣ Start with a sustainable withdrawal rate (3–4%).
2️⃣ Keep a cash buffer for bad years.
3️⃣ Stay invested enough to beat inflation.
4️⃣ Adjust your spending when needed.
Do that, and your money won’t just last — it’ll work smarter for you, giving you the freedom to enjoy retirement without fear of running out.
