UK Family Income Benefit Explained

Family income benefit is a form of life insurance that pays a regular income for the rest of the policy term, rather than a lump sum, on death. It is typically used to replace the insured's income to dependants over a defined period such as until children are independent.

How FIB works

The policy is taken out for a fixed term (e.g. 20 years). If the insured dies during the term, the policy pays a regular monthly or annual amount from the date of death for the remainder of the term. A death at year five of a 20-year policy results in 15 years of payments; a death at year 19 results in one year of payments.

Cost vs lump sum

FIB premiums are typically lower than equivalent lump-sum cover for the same nominal annual income. The trade-off is that the total payout depends on when in the term death occurs.

Suitable use cases

FIB suits households that need income replacement for dependants over a defined period, such as until children finish education. It tends to be easier for many households to budget around than a lump sum that must be invested or drawn down.

Combining with lump-sum cover

Many households combine FIB (for income replacement) with decreasing-term life (for mortgage clearance) and income protection (for living-but-unable-to-work scenarios). The combination is often cheaper than a single large lump-sum policy.

How FIB works in detail

The policy is taken out for a fixed term (e.g. 20 years). If the insured dies during the term, the policy pays a regular monthly or annual amount from the date of death for the remainder of the term.

A death at year 5 of a 20-year policy results in 15 years of payments; a death at year 19 results in 1 year of payments. The total payout depends on when in the term death occurs; the later the death, the less is paid.

The policy pays from the date of death (or shortly after, depending on claim processing) for the rest of the term. The income provides regular replacement for the insured's earnings, supporting the household's ongoing essential outgoings.

FIB suits households where the protection need is income replacement over a defined period (such as until children finish education). The structure mirrors the household's actual income needs more directly than a lump sum that must be invested or drawn down.

The benefit period can be set to match specific household milestones: until the youngest child reaches 21; until the mortgage is paid off; until the partner's expected retirement age; or other relevant horizons.

Cost vs lump sum

FIB premiums are typically 25% to 50% lower than equivalent lump-sum cover for the same nominal annual income. The cost saving reflects the decreasing total payout over the term: a death at year 1 produces the maximum payout; a death at year 19 produces minimal payout.

For example, a 25-year FIB policy paying GBP 30,000 per year has a maximum payout of GBP 750,000 (if death at year 1, with 25 years of payments). The premium reflects the average expected payout, not the maximum.

An equivalent level-term lump-sum policy might insure GBP 400,000 (about half the maximum FIB payout). The lump-sum policy pays GBP 400,000 regardless of when in the term death occurs; the FIB pays a decreasing total. The structures are not directly comparable but provide different value propositions.

For dependants, the FIB structure may be easier to manage than a large lump sum. Receiving GBP 2,500 per month for 25 years requires less financial management than receiving GBP 400,000 to invest and draw down over the same period.

Suitable use cases

FIB suits households that need income replacement for dependants over a defined period, such as until children finish education. The structure mirrors the actual income need rather than providing a lump sum.

Households where the surviving partner is not financially literate or confident may prefer FIB to lump sum cover because the regular income removes the investment decision. The trustees (if in trust) or the named beneficiary receives the monthly payments without needing to manage investments.

FIB tends to be easier for many households to budget around than a lump sum. The monthly income replaces the lost earnings predictably; the household can plan around the income just as they planned around the original salary.

FIB does not provide for one-off costs that a lump sum could cover (such as paying off the mortgage immediately, funding a child's university, or providing for a major life event). For households needing both types of provision, combining FIB with a separate decreasing-term mortgage protection and a lump-sum policy for one-off needs is common.

Combining with lump-sum cover

Many households combine FIB (for income replacement) with decreasing-term life (for mortgage clearance) and income protection (for living-but-unable-to-work scenarios). The combination is often cheaper than a single large lump-sum policy.

Example structure for a 35-year-old with a GBP 200,000 mortgage and 2 children: decreasing-term life of GBP 200,000 over 25 years (matched to mortgage); FIB of GBP 30,000 per year over 20 years (income replacement until children are independent); income protection of GBP 2,500 per month to age 65 (for illness or injury preventing work).

Total monthly premium for this layered structure might be GBP 50 to GBP 90 per month for a healthy non-smoker. The cover combines: GBP 200,000 to clear the mortgage on death; GBP 30,000 per year for 20 years on death (max GBP 600,000); GBP 2,500 per month if unable to work to age 65.

Trust placement for FIB

Like other life insurance, FIB can be written in trust for IHT efficiency and faster payment. The trustees receive the income payments and distribute according to the trust deed.

The discretionary trust structure is common for FIB. The trustees can use the income for the named beneficiaries (typically spouse and children) according to current circumstances. This flexibility suits FIB's long payment period during which family circumstances may change.

Some FIB policies allow the income to be commuted to a lump sum at the time of claim, at a defined factor. The commutation factor reflects the time value of the remaining payments; the lump sum is less than the total remaining payments would be in nominal terms.

Worked comparison: FIB vs lump-sum cover

A worked comparison clarifies the cost-benefit trade-off. Consider a 35-year-old non-smoker seeking protection for a partner and two young children over a 20-year period.

Option A: GBP 30,000 per year FIB over 20 years. Maximum potential payout: GBP 30,000 x 20 = GBP 600,000 (if death in year 1). Typical premium: GBP 18 per month.

Option B: GBP 400,000 lump-sum level term life cover over 20 years. Payout: GBP 400,000 regardless of when in term. Typical premium: GBP 30 per month.

Option C: Combination of GBP 200,000 decreasing-term life cover (matching a typical mortgage) plus GBP 20,000 per year FIB over 20 years. Total monthly premium: approximately GBP 25.

For a family where the protection need is primarily income replacement (such as for monthly bills and children's costs), FIB is cost-efficient. For a family with a specific lump-sum need (such as clearing a mortgage), decreasing-term life is cost-efficient. Combination structures provide layered cover at typically lower total cost than a single large lump-sum policy.

The practical takeaway: matching the protection structure to the actual need (income vs lump sum) optimises both cost and outcome.

Frequently asked questions

Is the FIB payout indexed?

Some FIB policies include indexation, which increases the income annually (typically by RPI or CPI). Premiums also rise correspondingly. Indexation preserves the real value of the income over the term; without indexation, inflation erodes the purchasing power. For longer terms, indexation is typically valuable; for shorter terms, the inflation impact is smaller.

Can the payout be commuted to a lump sum?

Many FIB policies allow the income to be commuted to a lump sum at the time of claim, at a defined factor. The commutation factor reflects the time value of the remaining payments; the lump sum is less than the total remaining payments would be in nominal terms. The commutation option provides flexibility for dependants needing immediate capital.

Is the income paid to the policyholder's estate?

Typically to named beneficiaries or trustees if the policy is in trust, which is preferable for tax and probate reasons. Without trust, the income goes to the estate; trust placement provides IHT efficiency and faster payment. Trust placement is particularly valuable for FIB given the long payment stream.

Does FIB cover critical illness as well?

Some policies include a critical illness option that pays the income on diagnosis as well as on death. Check the specific product. The combined cover provides income replacement for both major scenarios. The cost is typically higher than pure FIB but lower than separate CI and FIB policies.

Are FIB premiums level for the term?

Most are level. Some use reviewable premiums; check the specific product. Level premiums provide certainty over the term; reviewable premiums may rise at periodic reviews based on the insurer's claim experience. Indexed FIB has growing premiums as the income grows.

Is FIB suitable for short-term needs?

FIB is typically used for longer-term protection (15+ years). For short-term needs, lump-sum cover or specific short-term income protection may be more suitable. The cost advantage of FIB is most pronounced for longer terms; short-term FIB has less premium advantage.

Can FIB be combined with mortgage protection?

Yes. A common structure is decreasing-term mortgage protection plus FIB for ongoing income replacement. The decreasing-term clears the mortgage on death; the FIB provides regular income for the surviving dependants. The combined structure covers both the major debt and the ongoing income need.
