A method of calculating a premium payable by an insured person on a life insurance policy uses the amount of claims made from a health insurance plan of the insured person and information regarding the general well-being and/or lifestyle of the insured person to calculate the premium payable. The premium is calculated using a base percentage amount which is then either increased or decreased. If the insured person has made few claims to the health insurance plan and they have taken positive steps to look after their health, they will be rewarded by a relatively lower premium on their life insurance policy.
