What is the Longevity Risk Calculator?
The Longevity Risk Calculator helps you understand whether your money will outlive you and whether delaying life today comes at the cost of your best, healthiest years. It shows how different retirement ages, spending levels and income sources affect the balance between “time you have left” and “money you have left”, helping you decide whether working longer is worth the trade-off.
How the Calculator Works?
This calculator runs multiple lifespan scenarios based on UK life expectancy, healthy-life expectancy and long-life probabilities. You enter your pensions, investments, State Pension and retirement spending. The tool then tests:
- Do you risk running out of money if you live longer than expected?
- Do you risk giving up too many good years by working too long?
- How far could small changes such as part-time work, reduced spending, or phased retirement improve the balance?
Instead of focusing only on surviving old age financially, the tool highlights whether your plan gives you enough good life while you’re still healthy enough to enjoy it.
Step One: Enter Your Finances and Retirement Age
Add your age, retirement target, pensions, ISAs, GIAs and cash. This sets the foundation for testing whether your money is likely to last.
Step Two: Choose Lifespan and Healthy Years Scenarios
Test against typical UK life expectancy, optimistic scenarios and “live longer than average” outcomes. You can also factor in healthy life expectancy, the years when you are most active.
Step Three: Review Your Balance of Time vs Money
The tool reveals whether your money is likely to outlive you, or whether your best years risk running out first. Adjust income, part-time work, retirement age or spending to find a more fulfilling balance.

What is the Longevity Risk Calculator?
The Longevity Risk Calculator highlights whether your money outlives you — or your best years outlive your retirement. It helps you find a better balance between financial security and time freedom.
What is longevity risk?
Longevity risk is the possibility that your money runs out before you do. But it also includes the less-discussed risk: working too long and losing your healthiest years to employment.
How does this calculator help me balance work and life?
Instead of focusing only on “not running out of money”, it shows the trade-off between delaying retirement for financial security and losing years of health, mobility and time while saving.
What information do I need to use it?
You’ll need your retirement age, pension and investment balances, spending needs and any income sources (DB pensions, rental income, State Pension).
What does healthy life expectancy mean?
It’s the average number of years people in the UK remain active and well. For many, this ends years before total life expectancy, meaning waiting too long to retire reduces the years you can fully enjoy.
Can it help me explore alternatives to working full-time?
Yes. You can test scenarios such as phased retirement, lower spending, part-time income or reduced withdrawal rates to find a balance between financial security and time freedom.
Does it include the State Pension?
Yes. You can set the start age and number of recipients to model how it supports later-life finances.
Could working part-time reduce longevity risk?
Often yes. Even modest part-time income can extend your portfolio significantly and help you retire from the stressful parts of work sooner.
