Life Cover Needs Calculator

Life insurance need = income replacement + debts + lump sum for dependants, minus existing cover. This calculator shows exact shortfall to inform policy amount.

50k income × 10 years = 500k replacement + 250k mortgage + 50k dependant fund = 800k total need. Existing cover 100k. Shortfall: 700k additional cover needed.

Term life insurance for 700k at age 35 typically 15-30/month. Cheap insurance for significant protection. Most households under-insured - run the tool to size the gap honestly.

Run it with sensible defaults

Using annual income of 50,000, years of replacement of 10, existing life cover of 100,000, outstanding debts of 250,000, the calculation works out to 700,000.00. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Annual Income, Years of Replacement, Existing Life Cover, Outstanding Debts, and Dependants Care Lump Sum — do not pull with equal force. Not every input has equal weight. Adjusting one input at a time toward extreme values shows which ones move the result most.

How the math works

Total need = income × years + debts + lump sum. Shortfall = need - existing cover.

What the score tells you

Headline financial numbers — income, savings, debt — each tell part of the story. This calculation stitches several together into a single read you can track over time. The value is in the direction, not the absolute number.

What this doesn't capture

The score is a composite of the inputs you provide. Life context — job security, family obligations, health, housing — doesn't appear in the math but shapes the real picture. Use the number as a prompt, not a verdict.

Worked example

A 40-year-old earner with annual income of 75,000 wants to replace 15 years of that income should they pass away. They have an outstanding mortgage of 300,000 and want a 75,000 lump sum available for dependants' living costs and education. Their current life cover through an employer scheme is 100,000.

The calculation works as follows:

• Income replacement: 75,000 × 15 = 1,125,000
• Outstanding debts: 300,000
• Dependants care lump sum: 75,000
• Total need: 1,500,000
• Existing cover: 100,000
• Shortfall: 1,400,000

This estimate tells them that an additional 1,400,000 in cover would bridge the gap between their current protection and the total they've defined as adequate.

When this metric matters

This calculation is useful when:

• You have dependants who rely on your income and need to know how much protection to put in place
• You carry significant debt and want to ensure it would be covered
• Your employer-provided cover may not be enough for your family's needs
• You are reviewing life cover periodically as circumstances change
• You are deciding between different policy amounts or whether to add supplementary cover

What the result includes and excludes

What it includes: The calculation models income replacement over a defined period, outstanding liabilities, and a discretionary lump sum for dependants' needs. It then subtracts any existing cover you already hold.

What it does not include: Investment growth on remaining assets, inflation effects over the replacement period, changes to family circumstances, inheritance tax, ongoing expense changes, or the emotional and practical support networks beyond financial provision. The result is a static snapshot based on today's figures.

Educational illustration

This calculator is for educational and illustrative purposes. It models a straightforward formula and reflects only the inputs you enter. Actual life cover needs vary widely based on personal circumstances, local tax and legal factors, and individual priorities. This output should inform further conversation with a qualified financial adviser, not replace it.
