Step One: Enter Your Age and Basic Profile
Add your age and sex so the tool can load the correct ONS mortality baseline.
Step Two: Add Lifestyle Factors for Personalisation
Enter your weekly exercise, BMI band, alcohol intake and smoking status. These adjust your mortality curve based on relative risk patterns.
Step Three: Review Your Survival Curve and Planning Ages
See your personalised probability of reaching ages such as 70, 80, 85, 90 and beyond. Use the curve to explore realistic planning ages for retirement, gifting or major life decisions.

What is the Mortality Curve Forecaster?
It is a UK-focused tool that estimates your probability of reaching different ages based on ONS mortality data and lifestyle factors, helping you plan with more clarity around lifespan uncertainty.
What does this calculator estimate?
It estimates the probability of reaching different ages based on UK ONS mortality data and lifestyle-related risk adjustments. It shows likely, optimistic and low-probability outcomes.
How accurate is it?
It is a statistical estimate only. It cannot predict your personal health or lifespan, but it can help you understand realistic planning ranges for retirement and financial decisions.
Which lifestyle factors affect the curve?
Weekly exercise, BMI, alcohol consumption and smoking. These factors shift the probability curve up or down using established relative risk relationships.
Why does this matter for retirement planning?
Understanding longevity uncertainty helps you balance saving enough for later life without delaying your best years. It can influence decisions around retirement age, spending levels and gifting.
Does it consider genetics or medical history?
No. It uses general population data plus lifestyle adjustments. For personalised medical guidance, you should speak with a clinician.
Does the tool include healthy life expectancy?
The main output is survival probabilities, but you can interpret the earlier part of the curve as your highest-probability “healthy years”. You can look at ‘healthy years’ via our Longevity Risk Calculator.
