Most of us understand that inflation pushes up the cost of everyday essentials, from food shopping to energy bills. But fewer people realise it can also reduce the future value of their protection cover.
If you have life insurance or critical illness cover, the amount paid out might stay the same while the cost of living continues to rise. Over time, that could mean the policy provides less financial support than you originally intended. That’s why it’s worth considering ways to help your protection cover keep pace with inflation, so it continues to provide a valuable safety net for you and your loved ones.
It can be helpful to keep tabs on your everyday costs and outgoings – the mortgage, energy bills, petrol, and food shopping. It supports your household budgeting and helps you feel in control. It can also help you understand how much protection, such as life insurance, critical illness, and income protection cover, you may need.
Many people will have felt the effects of rising costs in recent years as prices have increased. This is inflation reducing the purchasing power of your money. It means the same amount of money today may buy less in the future.
Niki Patel, tax and trust specialist at St. James's Place, says: “The higher inflationary environment of the last few years is a reminder that the spending power of money changes over time. This is an important factor to consider when taking out or reviewing a long-term insurance policy.
“The benefit or payout from a critical illness, income protection or life assurance policy could have much less spending power in a decade or longer if it doesn’t increase over time.”
When you take out a protection policy, there will usually be the option to index link the benefits. This is known as indexation.
Depending on the policy, cover may increase in line with an inflation measure, such as the consumer price index (CPI), an earnings measure, or by a fixed percentage each year.
This can make a substantial difference to your benefits over time. For example, £200,000 of cover increasing by 3% each year would grow to around £269,000 after 10 years, and around £361,000 after 20 years.
However, protecting the value of your cover through indexation is likely to mean that your premiums will also rise over time. It is important to consider this when weighing up the pros and cons of indexation.
The affordability of your premiums is an essential factor to consider when choosing or reviewing your cover. If you are unable to continue making payments then the policy will lapse, which could leave you worse off than before.
Here is a brief overview of how inflation could affect different types of protection:
Keeping your policy relevant in the face of inflation goes hand in hand with making sure it continues to reflect your circumstances.
Getting married or divorced, having children, changing jobs, buying a home and approaching retirement are examples of changes that could change your protection needs. These life events can provide a useful prompt to review your cover.
When reviewing your existing protection planning and cover, consider the following:
If you are unsure about what cover is right for you, or if your existing cover is still appropriate, a financial adviser can help by talking through the options and reviewing your current position.
Niki adds: “Protection planning is much more than simply putting cover in place. It’s also about making sure that cover continues to fulfil the purpose it was designed for.”
