    Choosing the right amount of life insurance is one of the most important financial decisions you'll make. Too little and your family struggles; too much and you're wasting money. This guide gives you two methods to calculate the right coverage — plus costs, types, and common mistakes to avoid.

    Quick Coverage Calculator: 10x Salary Rule

    Your Salary × 10 = Recommended Coverage. Examples: £30,000 salary → £300,000 | £50,000 salary → £500,000 | £70,000 salary → £700,000. This is a starting point only — read on for a more accurate calculation.

    Detailed Coverage Calculation: The DIME Method

    DIME stands for Debt + Income + Mortgage + Education — the four financial obligations your family would face without you.

    1. Debt

    • Credit cards
    • Personal loans
    • Car finance
    • Funeral costs: £5,000–£10,000

    2. Income Replacement

    • Young children: 10–20 years of salary
    • Older children: 5–10 years of salary
    • No children: 3–5 years for spouse
    • Example: £40,000 salary × 15 years = £600,000

    3. Mortgage

    Outstanding mortgage balance — so your family can stay in the home debt-free.

    4. Education

    • State school: £0–5,000/child
    • University: £30,000–50,000/child
    • Private school: £100,000–200,000/child

    Example DIME total: Debt £20k + Income (15 yrs) £600k + Mortgage £200k + Education (2 kids) £60k = £880,000 total coverage needed.

    Types of Life Insurance

    1. Term Life Insurance (Most Popular)

    What it is
    Coverage for a specific term (10, 20, 30 years)
    Cost
    Cheapest option — from £12–18/month at age 25
    Payout
    Only if you die during the term
    Best for
    Young families, mortgage protection

    2. Whole of Life Insurance

    What it is
    Coverage for your entire life — guaranteed payout
    Cost
    5–10x more expensive than term
    Payout
    Guaranteed (eventually)
    Best for
    Estate planning, inheritance tax

    3. Decreasing Term (Mortgage Protection)

    Payout decreases as your mortgage decreases. Cheaper than level term — ideal for covering a repayment mortgage only.

    4. Critical Illness Cover

    Pays out if you're diagnosed with a serious illness — cancer, heart attack, stroke. Often added as an extension to term life for +£10–30/month.

    Who Needs Life Insurance?

    ✅ You need it if:

    • You have children (especially young children)
    • You have a mortgage
    • Your spouse/partner depends on your income
    • You have debts others would inherit
    • You're the primary breadwinner
    • You run a business with partners

    ❌ You probably don't need it if:

    • You're single with no dependents
    • You have no debt
    • You have substantial savings/investments (£500k+)
    • Your mortgage is almost paid off and kids are grown

    How to Get Lower Premiums

    • Buy young — a 30-year-old pays roughly half what a 40-year-old pays
    • Quit smoking — 12 months smoke-free qualifies you for non-smoker rates
    • Improve health — lose weight, lower blood pressure
    • Choose decreasing term if only covering your mortgage
    • Skip riders/add-ons you don't need
    • Compare multiple insurers — prices vary 30–50%

    Common Mistakes to Avoid

    1. 1Underinsuring — buying £100k when you need £500k leaves your family struggling
    2. 2Only insuring the main earner — a stay-at-home parent provides £30k–50k/year equivalent in childcare and household services
    3. 3Never reviewing coverage — review every 3–5 years or after a new baby, house move, or promotion
    4. 4Lying on application — claims are denied if you lied about smoking or health history
    5. 5Letting the policy lapse — missing payments cancels the policy; you can't reinstate at the same age and health

    Joint vs Separate Policies

    Joint Policy — Pros
    Cheaper (one policy premium)
    Joint Policy — Cons
    Only pays out once (first death); problematic if you divorce
    Separate Policies — Pros
    Each pays out independently; easier if divorced
    Separate Policies — Cons
    More expensive (two premiums)

    Recommendation: Separate policies for most couples, especially those with children.

    FAQs

    Can I be denied life insurance?

    Yes, for serious health conditions. But most people qualify — just potentially at higher premiums.

    Do I need a medical exam?

    Depends on coverage amount and your health. Under £500k with good health = usually no exam required.

    Is the payout taxed?

    No income tax on the payout. It may be subject to inheritance tax if paid to your estate — avoid this by putting the policy in trust.
