Level term vs decreasing term vs whole of life: which one is right for your family?

When you start shopping for life insurance as a new parent, you'll encounter three main policy types almost immediately: level term, decreasing term, and whole of life. They have different structures, different uses, and very different price points.

Most people pick one based on what a comparison site defaults to, or what an advisor recommends first. This guide explains what each one actually does, when it makes sense, and how to choose — without the industry jargon.

The three policies at a glance

Level term life insurance: the default for most parents

Level term is what most people mean when they say "life insurance." You choose a sum assured (the payout amount) and a term (the number of years the policy runs). If you die within the term, the insurer pays out the full amount. If you reach the end of the term alive, the policy expires and pays nothing.

The "level" part means the payout doesn't change. A policy written for $400,000 will pay $400,000 whether you die in year 2 or year 22. This predictability makes it the most useful option for protecting a family's finances — your partner knows exactly what they'd receive, which makes financial planning straightforward.

For new parents, level term is usually the right starting point because your financial exposure isn't just the mortgage. You also have:

• Lost income that your family would need to replace
• Childcare costs the surviving partner would face
• The ability to pay off other debts or provide financial stability

A payout that stays constant protects all of this, not just the mortgage balance.

According to comparison data from late 2025, 51% of customers were quoted less than $16.60 per month for a 10-year level term policy providing up to $175,000 cover. For a healthy non-smoking 30-year-old, $300,000 over 20 years typically costs $8–$16/month.

Decreasing term life insurance: the mortgage protector

Decreasing term cover is sometimes called mortgage life insurance because it's designed to sit alongside a repayment mortgage. As you pay down your mortgage each year, the potential payout on the policy also decreases — the idea being that your liability is shrinking, so your cover can shrink with it.

The main advantage is cost. Because the insurer's maximum payout decreases over time, the premiums are lower than equivalent level term cover. For a family on a tight budget who wants to ensure the mortgage is cleared if one partner dies, decreasing term cover achieves that goal cheaply.

When decreasing term makes sense

• Your primary concern is the mortgage, and your partner has sufficient income to manage other expenses
• You want the cheapest possible cover for mortgage protection
• You're buying it alongside a separate level term policy that covers income replacement

When decreasing term isn't enough

• You have dependants who would need ongoing financial support beyond clearing the mortgage
• You're a stay-at-home parent or the lower earner — your partner would need more than just mortgage clearance
• You want the surviving partner to have real financial breathing room, not just a cleared home loan

Cost comparison (non-smoking 32-year-old, $250k, 25 years):

The saving is real. Whether it's worth it depends on whether a reduced payout in later years still covers your family's needs.

Whole of life: not designed for new parents

Whole of life insurance has no fixed term. As long as you keep paying the premiums, the policy will pay out whenever you die — whether that's at 45 or 95. The insurer has no date at which the liability expires, which is why premiums are substantially higher.

The typical use case is inheritance tax planning. Wealthy individuals use whole of life policies to leave a guaranteed lump sum to their heirs, structured in trust to sit outside the estate for IHT purposes. It's a legitimate financial planning tool — but it's not what a 32-year-old with a new baby and a mortgage needs.

The most common mistake new parents make is buying whole of life insurance because it "lasts forever" and seems safer. In practice, paying substantially higher premiums throughout your 30s and 40s for a feature you don't need is poor value when the money could instead buy more term cover — or disability insurance — at a fraction of the cost.

The decision guide

A note on joint policies

Some couples buy a single joint life policy rather than two individual policies. Joint policies are cheaper in the short term — but they pay out only once, on the first death, and then terminate. If both partners die (uncommon but possible), there is no second payout.

Two individual level term policies typically cost only slightly more in total than a joint policy, and provide two potential payouts. For families with children, this structural advantage is usually worth the small additional premium.

Getting the term length right

Whatever policy type you choose, the term should align with your period of financial vulnerability. For most new parents, that means:

• Until your youngest child reaches 18 (or 21 if you expect to support them through university)
• Until your mortgage is paid off
• Whichever of the above is later

A 25-year term from age 30 takes you to 55 — when children are typically independent and the mortgage is close to clearance. This is the most common term for new parents in the US.
