Premium structures
There are three main types of insurance premium structures: stepped, level and hybrid, with stepped being the most common of these.
Stepped premiums are calculated on your age and will increase as the likelihood of making a claim increases. The sum insured may be fixed, may increase (where an indexation option has been selected) or may decrease (in the case of unitised cover).
As you are only paying for the level of risk associated with your current age, an insurance policy with a stepped premium structure will be more affordable in the short-term. However, the cumulative premiums will eventually eclipse those paid on an equivalent level premium policy, making this type of premium more expensive in the long-term.
Contrary to a stepped premium structure, level premium rates are based on your age at the time of application, thereby giving you a more consistent premium over the duration of the policy. It is important to note that level premiums may still change in the future due to changes in the Consumer Price Index (CPI) and increases in your sum insured, although any rises are likely to be considerably smaller than those experienced under a stepped premium structure. However, in order for a level premium policy to become cost-effective, you will need to continue to hold the policy with the same insurer for the long-term (i.e., a minimum of ten years) and will generally not be able to make significant changes to the sum insured or policy options.
In addition to stepped and level premiums, some insurers offer a third, less common option known as hybrid (or optimum) premiums, which begin on a loaded stepped structure and then convert to a level premium at a future anniversary date. Although you will pay less over the long run than you would under a stepped policy with the same sum insured, the premiums paid under a hybrid policy will exceed those paid under a traditional level premium policy. The below graph illustrates the cost differences between stepped, level and hybrid premiums:
