How to use our life insurance calculator

  1. 1Enter your take-home income and the number of years you want to replace it.
  2. 2Add your mortgage, other debts, funeral and estate costs, and the cost of supporting your children.
  3. 3Enter your existing life cover and savings to see how much additional cover your family may need.

Your life insurance calculation

The calculator estimates your potential life cover needs based on:

  • Your annual take-home income
  • The number of years of income you want to replace
  • Your outstanding mortgage and other debts
  • Funeral and estate costs
  • The number of dependent children
  • The estimated cost of supporting each child to independence
  • Existing life cover, including employer death-in-service benefits
  • Savings and investments available to your family

Your result

The calculator shows the estimated cost of replacing your income, clearing your mortgage and debts, supporting your children and covering funeral and estate costs. It then deducts your existing life cover and savings to show the potential additional life insurance cover you may need.

Our calculator is designed to be the start of a conversation. It provides an estimate based on the information you enter and does not model factors such as investment returns, inflation, State benefits or your partner’s income. If you have dependants or significant financial commitments, we’d encourage you to speak to a protection adviser to understand how much cover you may need and which type of policy could be appropriate.

How much life insurance cover do you need?

If you have a mortgage, children or other people who depend on your income, life insurance can help provide financial support if you die.

Our free UK Life Insurance Calculator helps you estimate how much life cover your family may need. It considers your income, mortgage and other debts, children’s costs, funeral and estate costs, existing life cover, and savings available to your family.

This can help you answer an important question: how much life insurance cover might my family need?

The result is an illustration rather than a recommendation. The right level of cover will depend on your family’s circumstances, financial commitments and existing sources of income and protection.

How much income should life insurance replace?

If your family relies on your income, replacing some or all of that income may be an important part of your life insurance needs.

The amount and period will depend on your circumstances. For example, a family with young children may need income replacement for longer than a household where children are already financially independent.

Your partner’s income, savings and other sources of financial support can also affect how much cover is required.

There is no single income multiple that works for everyone, so it can be useful to look at your actual household spending and future financial commitments.

Should life insurance cover my mortgage and debts?

Your mortgage may be one of the largest financial commitments your family would have to deal with if you died.

You can include your outstanding mortgage and other debts, such as personal loans or credit cards, in the calculator. This helps estimate how much additional money your family might need to clear those commitments.

Whether you want a policy to cover all of these debts will depend on your wider financial position and the type of cover you choose.

How much life insurance do I need for my children?

Children can create significant long-term financial commitments, particularly if you want to allow for education, private schooling or other costs until they become financially independent.

The calculator lets you enter the number of dependent children and an estimated cost of supporting each child.

Your actual costs will depend on your family and the choices you expect to make. You may also want to consider how your children’s needs could change as they get older.

What if I already have life insurance?

You may already have some life cover through your employer or an existing personal policy.

Death-in-service benefits can form part of your overall protection, but they are linked to your employment and the amount of cover can vary between employers.

The calculator allows you to include existing personal and employer life cover, along with savings and investments that could be available to your family. This helps estimate any additional cover you may need.

It’s also worth checking whether existing employer cover would continue if you changed jobs.

What type of life insurance do I need?

The type of cover you need will depend on what you are trying to protect.

Term life insurance provides cover for a specified period. This can be used to protect a mortgage, replace income while children are dependent or cover other financial commitments during a particular stage of life.

Whole-of-life insurance is designed to provide cover for the rest of your life, subject to the policy terms and premiums being maintained. It can be used for different planning purposes, including some estate planning situations.

The amount and type of cover are separate decisions, so it can be useful to consider what you want the policy to achieve before choosing a policy.

Should I speak to a financial adviser about life insurance?

A life insurance calculator can help you understand how much cover your family may need, but it cannot account for every aspect of your circumstances.

A regulated financial adviser can help you consider how life insurance fits alongside your mortgage, income, savings, pensions and wider financial plans. They can also help you understand the different types of cover available and how factors such as policy terms, exclusions, premiums and trusts could affect your protection.

Before taking out cover, it can be useful to consider not just the amount of insurance you may need, but also the cost of the policy, how long you need the cover for and what would happen if your family’s circumstances changed.

If you would like help assessing your options, you can use the Trusted Advisor adviser matching service to find a regulated financial adviser suited to your needs. Alternatively, email our team at hello@trusted-advisor.co.uk and we can help you understand the next steps.

Frequently asked questions

Term covers a defined period - for example until your mortgage is paid or your children are independent - and is generally less expensive. Whole-of-life pays out whenever you die and is typically used for estate or Inheritance Tax planning rather than family protection.

A death-in-service benefit is usually 4× salary - often less than a family needs - and disappears if you change employers. Most financial advisers recommend topping up with personal cover that travels with you.

Almost always yes. Writing a policy in trust keeps the payout outside the estate for IHT and speeds up payment to beneficiaries.

The payout falls over the term, roughly in line with a repayment mortgage, so it costs less than level cover. Level cover is better suited to replacing family income.

Only if someone still relies on your income or you have debts to clear. Whole-of-life cover can also be used, where appropriate, to provide funds to help meet an inheritance tax liability.

The cost of life insurance depends on factors such as your age, health, lifestyle, smoking status, occupation, the amount of cover and the length of the policy. Your premium can also vary depending on whether you choose single or joint cover and any additional features included in the policy.

Yes. Insurers may consider your current health, medical history, family medical history, lifestyle and whether you smoke when assessing the cost of cover. Depending on your circumstances, you may be offered different terms or a higher premium.

A joint life policy can be cheaper than taking out two separate single-life policies, but it will generally pay out on the first death only. Two single policies can provide separate cover for each person, so the right option depends on your circumstances and what you want the policies to achieve.

Yes. Life insurance can be used to provide liquidity to help beneficiaries meet an Inheritance Tax bill without having to sell property, investments or other assets at short notice. For larger estates, the policy and its ownership structure need to be considered carefully as part of the wider estate plan.

Yes. Life insurance can be used as part of a business protection arrangement to provide funds following the death of a business owner or key person. This can help a business manage the financial impact of losing an owner or key individual and, depending on the structure, provide funds to support the purchase of a deceased owner’s interest.

For larger estates, life insurance can form part of a wider estate-planning strategy alongside wills, trusts and other arrangements. A policy may provide liquidity for tax or other liabilities, while placing a policy in an appropriate trust can affect how the proceeds are managed and distributed. The tax and trust rules can be complex, so the structure should be considered with appropriate professional advice.
