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.
Should I plan to average life expectancy or beyond it?
Plan beyond the average because plenty of people live longer than it. Use one central age and another version that runs well into later life, especially if investments are paying for the basics. The calculator is not predicting your death. It is checking whether the money lasts if you live longer than average.
How do survivor benefits change longevity risk for a couple?
A couple’s plan should usually run until the second death, not the first. After one partner dies, one State Pension may stop and a defined benefit pension may reduce, while housing costs continue. Test the survivor’s income and budget separately rather than using one joint life expectancy.
Can an annuity reduce longevity risk?
Yes, because lifetime annuity income is designed to continue however long you live, subject to the product terms. You give up access to the capital used and the starting rate may be lower if you add inflation or partner protection. It can be useful for essential spending even when the rest stays invested.
What is the non-financial side of longevity risk?
A longer life is not just a larger bill. It may mean more healthy years, family time and choices, as well as a greater chance of needing help later. Keep enough for later life without postponing everything enjoyable while health and energy are stronger. Both stages matter.

Behind Retirement Calculators
Built from the questions I was asking myself
I'm Ryan, the person behind Retirement Calculators. I started the site after selling an online business and trying to understand what our pensions, ISAs, investments and property actually meant for the way we wanted to live.
The calculators are built around those real decisions: whether you could work less, retire earlier, spend more now or use your money differently. They will not give you a perfect answer, but they can make the trade-offs much easier to see.
