£500,000 Life Insurance: At a Glance
A £500,000 life insurance policy provides substantial financial protection for your family, covering mortgage repayments, living expenses, and future goals like education costs. But how much will it actually cost you each month?
The answer depends on three key factors: your age, your health and lifestyle (especially smoking status), and the type of policy you choose. In this guide, we break down typical 2026 premiums and help you estimate your costs using our interactive calculator.
Key insight: Premiums roughly double or triple from your 20s to your 40s. The younger and healthier you are when you apply, the lower your premiums will be—locked in for the entire policy term. For more details on how age affects pricing, see our comprehensive life insurance guide.

Level Term Life Insurance Costs
Level term is the most common type of life insurance. It pays the full £500,000 if you die during the term, and premiums stay the same throughout.
| Age | Monthly Cost Range | Annual Cost |
|---|---|---|
| 20 | £8.80 – £12.00 | £106 – £144 |
| 25 | £12.00 – £15.00 | £144 – £180 |
| 30 | £15.00 – £20.00 | £180 – £240 |
| 35 | £20.50 – £30.00 | £246 – £360 |
| 40 | £32.00 – £47.00 | £384 – £564 |
| 45 | £48.00 – £75.00 | £576 – £900 |
| 50 | £74.00 – £130.00 | £888 – £1,560 |

Decreasing Term Life Insurance Costs
Decreasing term insurance is often used for mortgage protection. The payout decreases over time (matching a reducing mortgage balance), making premiums significantly cheaper than level cover.
| Age | Approx Monthly Cost | Savings vs Level Term |
|---|---|---|
| 20 | ~£7.80 | Save ~10-35% |
| 25 | ~£8.40 | Save ~30-44% |
| 30 | ~£9.70 | Save ~35-52% |
| 35 | ~£13.20 | Save ~36-56% |
| 40 | ~£19.50 | Save ~39-59% |
| 45 | ~£30.80 | Save ~36-59% |
| 50 | ~£54.30 | Save ~27-58% |
Decreasing term is ideal if your main goal is mortgage protection. Learn more about choosing between these options in our term vs whole life insurance comparison.
Whole of Life Insurance Costs
Whole of life policies guarantee a payout whenever you die (as long as premiums are paid). They're typically used for estate planning, inheritance tax planning, or ensuring funeral costs are covered—but they're much more expensive.
| Age | Approx Monthly Cost | Why So High? |
|---|---|---|
| 20 | ~£260 | Guaranteed payout |
| 25 | ~£280 | Guaranteed payout |
| 30 | ~£310 | Guaranteed payout |
| 35 | ~£360 | Guaranteed payout |
| 40 | ~£420 | Guaranteed payout |
| 45 | ~£495 | Guaranteed payout |
| 50 | ~£530 | Guaranteed payout |
Important: Whole of life is best for specific planning needs like IHT mitigation. For most families, term insurance offers better value for pure protection.
Key Factors That Affect Your Premium
Age
The single biggest factor. Premiums roughly double or triple from your 20s to your 40s because of increased mortality risk. The younger you buy, the cheaper your lifelong premiums.
Smoking Status
Smokers pay 70-100% more due to significantly increased health risks. This includes vaping and nicotine products in most policies. Learn more in our smokers vs non-smokers guide.
Health & Lifestyle
Medical history, BMI, occupation, and dangerous hobbies all affect your rate. Pre-existing conditions don't necessarily mean rejection—see our guide to calculating cover needs.
Policy Term & Type
Longer terms cost more per month. Decreasing term is cheapest, level term is mid-range, and whole of life is most expensive due to guaranteed payout.
Tips to Get the Best Price
Buy Early
Premiums are lowest when you're young and healthy. Lock in rates now—they won't increase during your policy term.
Compare Multiple Providers
Prices vary significantly between insurers. Always get quotes from several providers before committing.
Choose the Right Term Length
Match your term to your needs—until your mortgage is paid off, or until your children are financially independent.
Consider Decreasing Term for Mortgages
If your main goal is mortgage protection, decreasing term offers substantial savings with appropriate coverage.
