How Much Life Insurance Do You Need as an Expat?

Why the Question Matters More for Expats

Life insurance is, at its core, a financial calculation: what would your dependants need if your income stopped today? The answer to that question determines the sum assured you should seek. Get it right and the policy performs its purpose. Get it wrong — by insuring too little — and the policy provides false assurance.

For expats, getting the calculation right matters more than it does for UK-resident clients, because the safety nets that UK residents take for granted do not exist in most international locations. The UK state provides Bereavement Support Payment (for those with dependent children) and child benefit. It provides NHS healthcare at no direct cost. It provides free state education. None of these exist in the same form for a family living in the UAE, Thailand, Spain, or any of the other countries where Global Investments' clients typically reside.

The financial consequence of underinsurance for an expat family — a surviving partner with no local state support, children in fee-paying international schools, a mortgage or rent commitment, and a lifestyle built on a joint income — is more severe than for a comparable UK-resident family. The calculation deserves proportionately more care.

Method One: The Income Replacement Approach

The most widely cited starting point for calculating life insurance is a multiple of annual gross income. The commonly used figure is ten times income, though fifteen times is used for higher earners or those with longer-term dependants.

A 40-year-old earning £120,000 a year would use this approach to arrive at a sum assured of £1.2 million to £1.8 million. The rationale is that the lump sum, invested conservatively, could generate or replace a meaningful income stream for a substantial period — allowing the surviving family to maintain their standard of living without immediately liquidating assets or downsizing dramatically.

The income multiple approach has genuine utility as a first approximation, but it has significant limitations:

It does not account for the actual income your surviving dependants would need. If your partner earns £60,000 a year, the income replacement need is only the shortfall between your combined income and what they can maintain on their salary alone. Mechanically applying a multiple to your gross income ignores their contribution.

It does not account for existing assets. If you have £400,000 in savings and investments that your partner could access, the lump sum required from a life policy is reduced by that amount.

It does not account for the time horizon. A ten-times multiple may be sufficient if your children will be financially independent in eight years but inadequate if you have a newborn and 22 years of financial dependence ahead.

Use the income multiple as a floor, not a ceiling, and use the methods below to stress-test and refine it.

Method Two: The DIME Framework

The DIME method is a structured approach to calculating the sum assured by building up four components:

D — Debt. Total all outstanding debts, excluding the mortgage (which is addressed separately). This includes car finance, personal loans, credit cards, and any other obligations that your estate would need to clear. Dependants should not inherit unmanageable debt.

I — Income. Multiply your annual income by the number of years your dependants will need income replacement. A rough guide is the number of years until your youngest child reaches financial independence, or until your partner reaches pension access age, whichever is later. For a couple with a two-year-old child where the partner is 38, that might be 18 years of income replacement need.

M — Mortgage. The outstanding mortgage balance. If your dependants would need to clear the mortgage to maintain their housing security — particularly relevant where the surviving partner's income alone could not sustain repayments — include the full outstanding balance.

E — Education. The total estimated cost of educating your children to the age of financial independence. For expats in international private schools, annual fees of $15,000–$40,000 per child are not unusual depending on location and school. University costs add a further £50,000–£150,000 per child depending on the country of study. For a client with two children in international school and eight years until university, this component alone could reach £400,000–£800,000.

Adding the four DIME components gives a total capital need. This figure is often considerably higher than the income multiple method suggests, particularly for clients with young children in expensive education systems — which is precisely the profile of many internationally mobile professionals.

Calculating Sum Assured for Mortgage Cover Specifically

Mortgage cover is the most commonly understood application of life insurance and the most straightforward to calculate. The sum assured should equal or exceed the outstanding mortgage balance at any point during the policy term.

For a capital repayment mortgage, the outstanding balance reduces each year as capital is repaid. Decreasing term cover — where the sum assured reduces in line with the mortgage balance — is a cost-effective way to cover this liability because the insurer's maximum payout reduces over time. A £400,000 decreasing term policy over 25 years will have a lower premium than a £400,000 level term policy over the same period.

For an interest-only mortgage — common among property investors — the outstanding balance does not reduce, and level term cover is more appropriate.

If you have both a residential mortgage and investment property mortgages, each should be considered separately. A policy covering only the residential mortgage leaves investment property debt outstanding, which may create liquidity problems for your estate if properties need to be sold to clear debt.

Expats with UK mortgages and international earnings should also consider the currency dimension. A sterling mortgage covered by a sterling policy is clean. A sterling mortgage covered by a USD policy requires currency exchange at claims stage, with associated rate risk — as discussed in more detail in our offshore policy guide.

Family Needs Analysis: Dependants, Partner's Income, and Children's Costs

A full family needs analysis goes beyond the DIME calculation to model the surviving family's financial position year by year after the policyholder's death.

The key inputs are:

Surviving partner's income. What would your partner earn independently? How does that change over time — will it increase as children become less dependent, or reduce as career gaps compound? If your partner has been primarily a carer and has limited independent earnings, the income replacement need is higher and longer-lasting.

Living costs. What does the household spend annually, and what would the surviving family need to maintain their standard of living? Costs that would reduce on your death (your own food, commuting, personal spending) should be subtracted. Costs that might increase (childcare, household help) should be added.

Children's costs. International school fees, extracurricular costs, university, and the period of transition to financial independence. These are often the largest single component of the family needs calculation for expats.

Housing. If the family would need to relocate after your death — either because the mortgage cannot be sustained, or because the current residence is tied to employment — relocation costs and any differential in housing costs should be modelled.

Healthcare. In most expat locations, private health insurance is the only healthcare option. The surviving family would need to continue this independently.

A formal family needs analysis, carried out by a protection adviser, will produce a detailed model of these figures. The resulting sum assured recommendation will typically differ materially from a rule-of-thumb income multiple — usually higher for younger clients with young children, and sometimes lower for older clients whose children are financially independent and whose assets are substantial.

Why Expats Often Need More Than UK Residents

The structural reasons why expat life insurance needs tend to exceed those of comparable UK residents are worth making explicit:

No state death benefits. UK Bereavement Support Payment (which replaced Widowed Parent's Allowance for deaths on or after 6 April 2017) provides, for those with dependent children, an initial lump sum of £3,500 followed by up to 18 monthly payments of £350, subject to National Insurance contribution conditions. For a family based overseas, this benefit is typically unavailable. The entire income replacement need must be met from private sources.

No employer group life cover. UK-based employees commonly benefit from employer-sponsored death-in-service cover of three to four times salary. Expats, particularly those working on international contracts, often lack this benefit — or lose it when changing employers. As noted in our overview guide, this cover ends entirely on the last day of employment and cannot be continued individually.

International school fees. State education in the UK is free. In most expat locations, the only viable option for English-medium education is a fee-paying international school. The financial consequence of the policyholder's death includes the continuation of these fees from private capital rather than from income.

Higher cost of living. Many expat locations — Dubai, Singapore, Hong Kong, parts of Spain — have higher baseline living costs than equivalent UK locations. The income replacement need is correspondingly higher.

Distance from extended family. UK-resident families can often call on extended family support — grandparents providing childcare, relatives providing temporary accommodation — that reduces the immediate financial burden after a death. Expat families based thousands of miles from extended family cannot rely on this to the same degree.

The Role of Existing Assets in Reducing the Sum Assured

Life insurance covers the gap between your dependants' needs and the assets already available to them. As your wealth accumulates, that gap narrows.

The following assets are relevant to this calculation:

Liquid savings and investments. Cash, ISAs, investment portfolios, and other liquid assets that your partner could access promptly and use to meet ongoing costs.

Property equity. The equity in property assets that could be realised through sale. Where selling the family home would be necessary and realistic, the net sale proceeds (after mortgage clearance and transaction costs) represent available capital.

Pension death benefits. UK pension plans typically pay a lump sum death benefit — often the value of the fund — on the member's death before retirement. This is a significant asset for many clients, but it is not always accessible promptly, depends on the scheme's nomination arrangements, and may have tax implications.

Existing life assurance. Any existing life policies already in force, whether UK-based or international, should be credited against the total need rather than double-counted.

Assets that are illiquid, contingent, or inaccessible should be discounted or excluded. A stake in a private business, for example, may have substantial theoretical value but may not be realisable on a useful timescale.

The net sum assured requirement — total capital need minus available assets — is the gap the life policy needs to fill.

Reducing Cover as Wealth Accumulates

Life insurance is not static. The sum assured appropriate for a 35-year-old with young children, a large mortgage, and limited savings is not the same as what is needed at 55 with a paid-off mortgage, significant investment assets, and children who are financially independent.

A regular review of your protection arrangements — ideally every two to three years, and always after a major life event — should reassess the sum assured in the context of your current financial position. As net wealth grows and outstanding liabilities shrink, the sum assured needed from pure life cover typically reduces.

This does not mean cancelling policies prematurely. The critical question is whether the policy has served its purpose for the period it covers. A 20-year level term policy taken out at 38 is designed to cover the period of maximum financial risk. Cancelling it at 45 because you feel financially secure is removing the net at a point when it is still protecting against a real risk.

Reducing sum assured over time is sometimes possible through policy endorsement. In other cases, the most practical approach is to take out a new policy for the reduced amount when the original term expires, reflecting both the reduced need and the (now lower) sum required.

Reviewing Cover After Major Life Events

The following life events should each trigger a review of your life insurance arrangements:

• New property purchase or mortgage. Both the sum assured and any decreasing term cover aligned to the old mortgage should be reassessed.
• New child. The education cost component of the family needs calculation changes substantially with each child.
• Change of employment. Particularly relevant when moving to a role that does not include employer group life cover.
• Divorce or separation. Beneficiary nominations and trust arrangements will likely need updating. The sum assured may change.
• Significant increase in income. Income replacement needs rise with earnings.
• Inheritance or windfall. A significant increase in liquid assets reduces the gap the policy needs to fill.
• Relocation to a new country. Policy portability should be confirmed, and any new financial liabilities assessed.

None of these events guarantee that an existing policy is wrong — but each warrants a review to confirm it remains appropriate.
