Start with spending, not a pot size
Most people understand retirement in monthly spending terms: bills, food, travel, hobbies, family support and everyday costs. The amount you need in pensions and savings depends heavily on that spending target.
Then account for guaranteed income
State Pension, defined benefit pensions and other reliable income can reduce the amount you need to withdraw from invested assets. Timing matters: income that starts at 67 does not fund spending at 58.
Accessible money can be as important as total money
A pension pot may be valuable but unavailable for early retirement years. Cash, ISAs and other accessible investments can help bridge the period before private pensions or State Pension begin.
Use benchmarks as context, not a rule
Retirement Living Standards can help frame lifestyle expectations. The current referenced annual benchmarks for a single person are £13,900 for minimum, £32,700 for moderate and £45,400 for comfortable. They are not personalised targets.
A practical way to estimate your number
- Choose a target monthly household spending amount.
- Add your State Pension forecast and any DB pension income.
- Separate accessible savings from pension money.
- Choose a retirement age and projection age.
- Test whether the projection remains funded.

Common questions
Is there a simple retirement savings target?
There is no single target that works for everyone. Your target depends on spending, retirement age, State Pension, other guaranteed income, investment returns, tax and how long the money needs to last.
Should I plan in monthly or annual spending?
Monthly spending is often easier to think about, while annual spending is useful for projections. RetirementInSight lets users enter monthly spending and converts it for the calculation.
