What it means
Universal life insurance combines a death benefit with a savings component called cash value. In the indexed version, the cash value grows according to how an equity index performs over a set period, usually a year.
If the index rises, the policy credits interest up to a limit, and if it falls, the credit is normally zero rather than negative. Two terms drive the outcome.
The cap is the maximum interest the insurer will credit in a period, and the floor is the minimum, often 0%. Some policies also use a participation rate, which credits only a percentage of the index gain.
This design gives protection from market losses in the credited interest, which appeals to people who want some growth without full stock market risk. The trade-off is that gains are limited by the cap, so strong market years are only partly captured.
Dividends from the index shares are generally not included in the index return. Costs matter a great deal.
The insurer deducts charges each month for the cost of insurance, administration and sometimes other fees, and these reduce the cash value even in years when interest is credited. Over the long term, policy performance depends on whether credited interest outpaces those charges.
Buyers should read the illustration carefully and compare it to a conservative case, not only the optimistic one. Rates and caps can change over time at the insurer's discretion.
Independent advice is wise before committing to a product that can last decades. It is also worth understanding how policy loans and withdrawals work.
Money can often be taken from the cash value, but doing so reduces the death benefit and may cause the policy to lapse if too much is taken. Tax treatment differs between countries, so local advice matters.
In practice
Real-world examples.
Example
A 40-year-old self-employed designer buys a policy to provide for her family and build tax-advantaged savings. She pays premiums for years. The cash value grows when the index rises and holds steady when it falls, apart from the monthly charges.
Example
A business owner uses an indexed policy as part of a plan to fund a buy-sell agreement with a partner. The death benefit pays out on his death. The cash value gives the company a reserve it can borrow against.
Example
A retiree reviews her policy and discovers that the cap has been lowered from 11% to 9%. She asks the insurer to explain. She decides to compare other products before paying more premiums, and asks for a written illustration of the guaranteed minimum.
Formula
Calculation
Credited interest rate = the lower of (Index return x Participation rate) and the Cap, but never below the Floor
Worked example: A policy has a cash value of $100,000, a cap of 10%, a floor of 0% and a 100% participation rate. In year one the index rises 14%, and in year two it falls 8%.
Year one credited rate = lower of 14% and 10% = 10%
Cash value after year one = $100,000 x 1.10 = $110,000
Year two credited rate = 0%, as the floor applies
Cash value after year two = $110,000 x 1.00 = $110,000
Monthly insurance charges would be deducted from these figures in practice, so the real cash value would be lower.Case study
Seen in the real world.
Willowbend Family is an illustrative, fictional household that bought an indexed universal life policy with a $500,000 death benefit. The agent's illustration showed strong cash value growth, using a steady 7% credited rate each year.
Over the first ten years, the index swung widely. The policy credited 10% in some years and 0% in others, and the average credited rate ended up well below 7%. Monthly charges continued whatever the index did.
In this illustrative story, the family needed to pay higher premiums than expected to keep the policy in force. They learned to ask for illustrations using lower credited rates and to review the policy annually.
Watch out
Common mistakes.
- Believing the cash value is invested directly in the stock market, when it only earns interest linked to an index.
- Expecting the full index return, when caps and participation rates limit the gains.
- Ignoring policy charges, when monthly deductions can erode cash value even in years of positive credited interest.
Questions
People also ask.
What does the floor do?
It sets the lowest interest the insurer will credit, often 0%, so the credited interest does not fall below it in a bad market year.
Can the cap change?
In many policies, the insurer can adjust caps and participation rates over time, so the current figures are not a promise.
Is the death benefit affected by index performance?
The death benefit is normally set by the policy design, but poor cash value growth can force higher premiums or reduce coverage.
