This independent UK guide helps you understand what the NHS Heart Age Calculator measures and directs you to the official NHS tool for the actual heart-age calculation. Heart age is based on a validated cardiovascular-risk model, so this page does not replace that model with a simplified or invented formula.

What is the NHS Heart Age Calculator?
The official NHS calculator compares your actual age with an estimated heart age using information about cardiovascular risk. The NHS states that its current calculations use the JBS3 Cardiovascular Risk Assessment. The service is a collaboration involving the NHS website, the Office for Health Improvement and Disparities, UCL and the British Heart Foundation.
Who can use the official NHS tool?
The current NHS service says it is suitable for people aged 30 to 95 who live in the UK and do not already have cardiovascular disease. The eligibility checker above covers only age and existing cardiovascular disease; the official service applies its complete process.
Information the NHS calculator asks for
The NHS tool asks about factors including age, sex at birth, ethnicity, smoking, height, weight and relevant health conditions. Blood pressure and cholesterol can also be entered. The NHS says the tool can still be used without blood-pressure or cholesterol details, although the result may be less accurate.
Why this page does not generate a heart-age number
Heart age is not a simple calculation based only on age, weight or blood pressure. The official NHS implementation uses JBS3 cardiovascular-risk calculations and multiple risk factors. To avoid presenting an invented or clinically misleading estimate, this independent page provides an eligibility check and links to the official calculation rather than substituting a simplified formula.
Understanding heart age
Heart age is intended to make cardiovascular risk easier to understand. A result should be considered alongside your wider health and risk factors rather than treated as a diagnosis. If you are worried about your heart or circulation, discuss your individual risk with a GP or another appropriate healthcare professional.
