About this calculator

Key person insurance is a policy a business takes out on someone it relies on, such as a director or key employee. HMRC describes it as a policy an employer takes out in its own favour against loss of profits caused by the death, critical illness, sickness, accident or injury of an employee, director or other key person. The business owns the policy and a valid claim is paid to the business.

Royal London’s guide says there are no specific rules for valuing a key person, but insurable interest must be shown. This calculator works out four ways that insurers’ own guides describe, side by side:

  • Multiple of remuneration: up to 10 times the key person’s yearly remuneration for life cover. With the starting figures that’s 10 × £60,000 = £600,000.
  • Share of net profit: up to 5 times the part of the business’s net profit that the key person brings in: 5 × £250,000 × 30% = £375,000.
  • Share of gross profit: up to 2 times their part of the gross profit: 2 × £600,000 × 30% = £360,000.
  • Replacement and lost profit: what it would cost to recruit and train a replacement, plus their part of the gross profit for the months until the replacement is up to speed: £20,000 + £600,000 × 30% × 12 ÷ 12 = £200,000.

The result is the range from the lowest to the highest of the four: £200,000 to £600,000 with the starting figures. The methods are alternatives, not amounts to add up. Scottish Widows, for example, sets key person cover at a maximum based on either the key person’s remuneration or the loss of profits attributable to them.

Use averages for the profit figures. Legal & General’s guide routinely uses an average of the last two years’ profit, and Scottish Widows averages net profit over the last 2–3 years. Royal London says that where a business has more than one key person, the profit may need to be split between them according to their contribution. Legal & General works out a key person’s share as their salary divided by the business’s total payroll in one of its formulas; the calculator lets you enter the share yourself. The months field stops at five years, the longest recovery period in that formula.

The multiples of remuneration are for life cover. Insurers allow less for critical illness cover: Legal & General considers a lower figure, and Royal London’s guide goes up to 5 times gross salary.

All figures are before tax. The calculator doesn’t allow for inflation or growth, although Royal London says higher multiples may be justified for a rapidly expanding business. Nor does it include a business loan: Royal London says an outstanding loan needs to be covered, divided between the key people as appropriate.

Key person insurance is business protection, which isn’t arranged through our quote forms. The quote form on this site is for personal life insurance, such as cover for your own family alongside any business policy. Legal & General tells businesses to speak to an adviser about how key person protection could work for them.

What each insurer’s guide allows on your figures

Each insurer publishes its own guidance on how much key person cover it will consider. The table shows the limits in the guides we checked, worked out on the figures you’ve entered, in alphabetical order. They’re limits, not recommendations: the insurer still underwrites each case and may ask for evidence of the figures.

Key person cover limits in insurers’ published guides, on your figures
Insurer and guide On your figures Published limit
Legal & General Key Person Protection Technical Guide £600,000 Often up to 10 times the key person’s earnings for death, with a lower figure for critical illness
Legal & General Key Person Protection Technical Guide £375,000 Up to 5 times the share of net profit directly attributable to the key person
Legal & General Key Person Protection Technical Guide £360,000 Up to 2 times the share of gross profit directly attributable to the key person
Legal & General Key Person Protection Technical Guide £180,000 Key person salary ÷ total payroll × gross profit × a recovery period of up to five years, using an average of the last two years’ profit Worked out here with the share of profit you enter and the time to replace them, up to five years.
Royal London Key person insurance, Technical Central £600,000 Up to 10 times gross salary, including benefits in kind, for life cover Up to 5 times gross salary for critical illness cover.
Royal London Key person insurance, Technical Central £375,000 Normally 5 times net profit, split between key people according to their contribution Higher multiples may be justified for a rapidly expanding business.
Scottish Widows Protection underwriting, business cover rules £600,000 Up to a maximum of 10 times total income, for life cover or life with critical illness cover Total remuneration includes basic salary, regular bonuses and/or dividends and other regular taxable income.
Scottish Widows Protection underwriting, business cover rules £375,000 Up to 5 times net profit averaged over the last 2–3 years, split by the percentage of profit attributable to the key person

The guides are from each insurer’s own adviser pages and documents, checked on the dates in the Sources list. Insurers can change them, and the policy terms when the business applies are what count.

Insurers also set a maximum amount of cover. Legal & General’s Key Person Protection goes up to £10 million for life cover only, subject to underwriting, and up to £3 million or £2 million with critical illness cover, depending on the total permanent disability definition. Aviva’s Business Life Insurance Options has no maximum for life cover only, and a maximum of £3,000,000 with critical illness cover without total permanent disability.

Larger amounts need more evidence. For Royal London’s Business Menu Plan life cover, above £2,500,000 it usually asks for a financial questionnaire and above £4,000,000 for corroborative evidence: for key person cover, audited accounts for the last 2 years and proof of income such as a P60. Its figures include any cover the person already has with Royal London or another provider.

Replacing a key person: the cost and the gap

Legal & General says a key person’s death could cost a business through lost profits or having to recruit or train a replacement, and that the amount of cover should take account of both. Its multiple of earnings is meant to cover the cost of finding a suitable person, training them and paying them while they develop in the role.

Zurich says finding the right person may take time and involve advertising and recruitment agency fees, and that key person cover can help with those and with training costs. Where the profit a key person is accountable for is known, it suggests cover that directly replaces that profit, “say for a year or two”, perhaps with some contingency. Royal London’s adviser guide says the key person’s contribution to profit should ideally be covered for at least a year.

The last method in the calculator follows that approach: the recruitment and training costs you enter, plus the key person’s share of gross profit for the months until a replacement is fully up to speed. Royal London may ask for the same figures when it underwrites: why the person is important to the business, their contribution to net or gross profit, and what it would cost to replace them.

Key person income protection

Instead of a lump sum, key person income protection pays the business a monthly benefit while the key person can’t work because of illness or injury. Royal London says the payments can compensate for lost revenue, pay a temporary replacement or fund sick pay for the key person. The table shows the most each policy’s published limit would allow a year on your figures.

Key person income protection limits, the most a year on your figures
Insurer and policy Most a year Published limit
Legal & General Key Person Income Protection (level cover) £150,000 Up to 2.5 times the key employee’s annual earnings to hire a temporary replacement, up to £250,000 a year
Legal & General Key Person Income Protection (level cover) £135,000 Up to 75% of the gross profit attributable to the key employee, up to £250,000 a year
Royal London Key Person Income Protection £135,000 75% of the gross profit attributable to the key person, up to £250,000 a year

Both policies let the business choose a deferred period of 4, 8, 13, 26 or 52 weeks before payments start. Royal London pays for 1 or 2 years, and Legal & General can limit each claim to 12 or 24 months. A key person can also return to work after a critical illness claim, so a lump sum could pay a temporary replacement or replace lost profits in the meantime.

How key person insurance is taxed

HMRC’s Business Income Manual says the premiums are allowable as a business expense only if the sole purpose of the insurance is the trade purpose of meeting a loss of trading income from losing the key person’s services, not a capital loss. A life policy must also be term insurance that pays only if the person dies within the term, with no other benefits, and the term shouldn’t go beyond the employee’s usefulness to the company.

Where both conditions are met, the premiums are deductible and money paid out under the policy is income of the employer’s trade, so it’s taxed as a trading receipt. As a general rule, where a policy doesn’t meet both conditions, the premiums can’t be deducted and the payout isn’t taxed as trading income, although HMRC says it can give no assurance that a future receipt will be left out of trading income. Premiums on whole life or endowment policies, or on critical illness or accident policies with an investment content, are capital expenditure and aren’t deductible.

Whether the sole purpose test is met is a question of fact, decided by what the directors or owners were trying to achieve. HMRC lists signs of a non-trade purpose, such as a policy that covers directors who are major shareholders but not other employees. Our guide to key person insurance explains the tax rules in more detail. An accountant can confirm how they apply to a particular business.

Key person insurance questions

Insurers’ guides use a few common methods: a multiple of the key person’s remuneration, often up to 10 times, a multiple of the profit they bring in, such as 5 times their share of net profit or 2 times their share of gross profit, or the cost of replacing them plus the profit lost in the meantime. The calculator above works out all four on your figures.

Enough to cover what the business would lose, within what insurers allow. Legal & General suggests looking at the effect on profits and the cost of hiring a replacement. The methods are alternatives rather than amounts to add together: Scottish Widows, for example, sets a maximum based on either remuneration or loss of profits. An adviser can help the business choose an amount and gather the evidence the insurer asks for.

It can be. HMRC allows the premiums if the sole purpose is to meet a loss of trading income from losing the key person and, for life cover, the policy is term insurance with no other benefits. Whether that test is met is a question of fact for each business.

Where the premiums are deductible, HMRC treats the payout as income of the employer’s trade. Where they aren’t, the payout generally isn’t taxed as trading income, but HMRC gives no assurance that a future receipt will be left out.

The business. When a company takes out key person cover with Legal & General, the company applies for and owns the policy, usually pays the premiums, and a valid claim is paid to the company.

Anyone whose death or disability would seriously affect the company’s future profits; some companies have several, others only one. Royal London says the size of someone’s shareholding isn’t necessarily a good guide, as an employee with no shares could easily be key.

Yes. Legal & General, for example, offers key person life insurance, life insurance with critical illness cover, and Key Person Income Protection, all owned and paid for by the employer.

No. Key person insurance is business protection, which isn’t arranged through our quote forms. Speak to a financial adviser who arranges business protection. Our quote forms are for personal life insurance, such as cover for your own family.
