Level vs Decreasing Term Life Insurance: Which Is Right for You?
Updated January 2026 · FCA Registered (989177)
Level term pays a fixed lump sum throughout the policy. Decreasing term reduces each year to mirror a repayment mortgage. If you only need to cover your mortgage balance, decreasing term is cheaper. If you want flexibility — income replacement, childcare costs, or debts beyond the mortgage — level term does more.
Level vs Decreasing Term: Side-by-Side Comparison
| Feature | Level Term | Decreasing Term |
|---|---|---|
| Payout amount | Same throughout the term | Reduces each year |
| Designed for | Family income, interest-only mortgages, general cover | Repayment mortgages |
| Monthly cost | Higher | Lower (typically 20–40% less) |
| Flexibility | High — payout can be used for anything | Lower — payout shrinks over time |
| Best for | Families, interest-only, income replacement | Repayment mortgage protection on a budget |
| Premiums | Fixed throughout | Fixed throughout |
How Decreasing Term Works in Practice
Imagine you take out a £200,000 repayment mortgage over 25 years. In year one, your outstanding balance is close to £200,000. In year 15, it might be around £110,000. By year 24, it could be just £15,000.
A decreasing term policy matches this pattern. If you die in year one, the policy pays out close to £200,000 — enough to clear the mortgage. If you die in year 15, it pays out roughly what remains on the mortgage. The policy reduces at a rate agreed at the start, typically assuming a specific interest rate (usually around 8%).
The key risk: if your mortgage interest rate is much lower than the assumed rate, the policy could reduce faster than your actual balance. It is worth checking this when you take out the policy.
How Level Term Works in Practice
A level term policy of £200,000 over 25 years pays £200,000 whether you die in year one or year 24. If you die in year 15 with £110,000 still on the mortgage, the remaining £90,000 goes to your family — to replace income, fund childcare, pay off other debts, or anything else.
That flexibility is why level term remains the most popular choice for families. Many couples with children choose level term at a higher sum assured than the mortgage balance, specifically to provide for living costs beyond just clearing the house.
Cost Comparison Example
Approximate monthly premiums for a non-smoker aged 35, £200,000 cover over 25 years:
| Policy Type | Approximate Monthly Premium | Total Paid Over 25 Years |
|---|---|---|
| Decreasing term (£200k) | £8–£12/month | £2,400–£3,600 |
| Level term (£200k) | £14–£20/month | £4,200–£6,000 |
| Level term (£300k) | £20–£30/month | £6,000–£9,000 |
Premiums vary based on age, health, smoking status, and insurer. These are illustrative figures only.

Common Questions
Which is better: level or decreasing term life insurance?
Neither is universally better — it depends on what you need the payout to do. Decreasing term is cheaper and perfectly matched to repayment mortgage cover. Level term costs more but pays the same amount whenever you die, making it the better choice for families who need more than just mortgage protection.
What happens if I die near the end of a decreasing term policy?
The payout near the end of a decreasing term policy can be very small — sometimes just a few thousand pounds — because the mortgage balance it was designed to cover has nearly been repaid. This is not a flaw; it is working as intended. Your mortgage would be almost paid off anyway, so little payout is needed.
Can I have both level and decreasing term life insurance?
Yes, and some families choose this combination deliberately. A decreasing term policy covers the mortgage balance while a level term policy provides income replacement for the family. Running both can be more cost-effective than a single larger level term policy, while giving full protection across all financial needs.
Frequently Asked Questions
What is the difference between level and decreasing term life insurance?
Level term life insurance pays the same fixed lump sum regardless of when you die during the policy term. Decreasing term pays a lump sum that reduces each year, designed to mirror a repayment mortgage balance. Level term is more flexible; decreasing term is cheaper and built specifically for mortgage protection.
Is level or decreasing term better for a mortgage?
Both work, but for a standard repayment mortgage, decreasing term is specifically designed to match your outstanding balance — and costs less as a result. Level term is better if you also want to protect family income or leave a lump sum beyond just clearing the mortgage.
Why is decreasing term life insurance cheaper?
Because the insurer's maximum payout falls every year. As your mortgage balance reduces, so does the potential claim amount, meaning the insurer's risk reduces over time. Level term keeps the same maximum payout throughout, so the insurer charges more to reflect that sustained risk.
Can I get joint level or decreasing term life insurance?
Yes. Both types are available as joint policies covering two people under one premium. A joint policy pays out once on the first death, ending the cover. Two single policies cost slightly more but each pays out independently — useful if both incomes are needed to cover ongoing costs.
Does decreasing term life insurance cover interest-only mortgages?
No. Decreasing term is designed for repayment mortgages where the balance reduces each month. If you have an interest-only mortgage your balance stays the same throughout the term, so you need level term life insurance to match it.
