What is 20 year term life insurance?

20 year term life insurance” describes a term-based life insurance policy which provides cover for a 20 year period. There are two common forms of term-based cover; level term and decreasing term.

Level term cover provides a fixed (or level) lump sum pay out regardless of when you pass away during the policy term.

In contrast, a pay out from decreasing term cover reduces over the lifetime of a policy, making it a good option to cover a repayment mortgage. Because the risk to the insurer reduces over time it’s usually cheaper than level term cover.

In the below article we explore the cost of life insurance over a 20 year term in 2025, listing a range of quotes from some leading insurers.

We provide fixed monthly premium prices over a 20-year term for:

  • Level term cover
  • Decreasing cover

Is a 20 year term life insurance policy right for me?

Whether a 20 year policy term is right for you and the needs of your family will depend on your individual circumstances.

For example, does the 20 year term mirror the length of your mortgage, protecting your family home until this sizeable debt is cleared?

Another key consideration when calculating an appropriate term is the age of your children. If your children are young, a 20 year term may provide the necessary protection until they have become financially independent. You may also want to consider whether you’re likely to have more children in the future.

All other criteria being equal, the longer the policy term, the higher the premium, as statistically a claim is more likely. Therefore, it’s worthwhile taking the time to calculate your ideal term, ensuring your loved ones are adequately protected, whilst not paying unnecessarily high premiums.

What happens after 20 year term life insurance?

Unlike life assurance policies, such as whole of life, which pay out when not if you pass away, a term-based policy only provides cover for a predefined period if you pass away.

Therefore, if you outlive your term policy your cover will elapse, and no pay out issued. For this reason, life insurance policies are significantly cheaper compared to life assurance policies, relative to the sum assured.
