What it means
Imagine paying $36,500 for a one-year property policy on 1 January. The insurer has the cash on day one, but it has only provided one day of cover.
The rest of the money pays for protection that lies ahead, so it cannot yet be counted as income. Insurers therefore split premium into earned and unearned portions.
The earned part relates to the days already elapsed and is recognised as revenue, while the unearned part is carried on the balance sheet as a liability called the unearned premium reserve. It shrinks every day as cover is provided and the premium is earned.
The reserve matters because it shows the insurer's obligation to provide future cover. If the insurer failed, policyholders would be owed protection or a refund for that period.
Regulators therefore require insurers to calculate it carefully, and analysts use it as a sign of future earnings, because it will turn into revenue over the coming months. The most common method is pro rata by time: premium multiplied by the fraction of the policy period remaining.
Some policies earn premium in line with the risk profile, for example for marine cargo or seasonal risks, but time-based calculation is the default. Policies sold in large numbers are usually calculated in batches by month, using simplifications.
For a business buying insurance, the same idea applies as a prepayment. The policyholder records the premium as a prepaid expense and recognises it gradually as cover is used.
Cancelling early usually produces a refund of the unearned part, sometimes reduced by a short-rate penalty or an administration fee. Reinsurance adds another layer.
When an insurer passes part of its risk to a reinsurer, it also passes on part of the premium, and the reinsurer holds its own unearned premium for the cover it still has to provide. Insurers therefore report unearned premium both gross and net of reinsurance.
In practice
Real-world examples.
Example
A construction company pays $120,000 for a twelve-month contractors' policy. After four months, the insurer has earned $40,000 and holds the other $80,000 as unearned premium.
Example
A delivery firm sells its vans and cancels the motor policy halfway through the year. The insurer calculates the unearned premium for the remaining six months and refunds it, less a small administration fee.
Example
An analyst reviewing an insurer's balance sheet sees the unearned premium reserve rising 15% in a year. She reads it as a sign that sales of new policies are growing and that revenue should rise in the following months. Rising unearned premium usually comes before rising revenue.
Formula
Calculation
Unearned premium = Premium x Remaining days / Total days in policy period
A business buys a 365-day policy for $36,500, starting on day 1.
After 100 days, 365 - 100 = 265 days remain.
Unearned premium = $36,500 x 265 / 365 = $100 x 265 = $26,500
Earned premium = $36,500 x 100 / 365 = $10,000
Check: $26,500 + $10,000 = $36,500. If the policy is cancelled at this point with no penalty, the policyholder would receive a refund of $26,500.
The daily earning rate is $36,500 / 365 = $100 a day, which makes the arithmetic easy to check at any date.Case study
Seen in the real world.
Kestrel General is an illustrative, fictional insurer that sold a large batch of annual policies in the final month of its financial year, collecting $18,000,000 of premium in December. Management was tempted to report the cash as revenue to meet its profit target.
Its finance team pointed out that, because cover began on 1 December, only about one-twelfth of the premium had been earned by year end. The remaining $16,500,000 had to be carried as unearned premium and would flow into revenue across the following year.
The company reported lower profit than hoped, but the numbers matched the cover actually provided. The illustrative story is a reminder that premium collected is not the same as premium earned. The board also agreed to show the unearned premium balance in its monthly management accounts, so that cash collected never gets confused with profit.
Watch out
Common mistakes.
- Counting all premium collected as income in the month it is received.
- Forgetting that a cancelled policy usually triggers a refund of the unearned part.
- Confusing unearned premium with unpaid premium, when one is cover not yet provided and the other is money not yet received.
Questions
People also ask.
Is unearned premium an asset or a liability for the insurer?
It is a liability, because the insurer owes cover or a refund for the remaining period.
How does a policyholder treat it?
As a prepaid expense, which is released to the income statement over the policy term.
Why do analysts watch the unearned premium reserve?
It indicates future revenue, because the balance will convert into earned premium over the coming months. The balance is released into revenue day by day, so an insurer with a growing reserve can expect higher earnings in later periods.
