What it means
A prepaid expense is money you've paid for something you'll use later: a year of insurance, an annual software plan, rent paid ahead. On the day you pay, you haven't used any of it. You've swapped cash for a right to future coverage or service.
Accounting treats that right as an asset, meaning something the company holds that has future value. It turns into an expense only as the months pass and you actually use it.
The payment is recorded in a prepaid account on the balance sheet instead of an expense account. Each month, that month's share moves from the prepaid to the matching expense line on the P&L, usually straight-line, meaning the same amount every month.
A prepaid schedule lists each contract with its start date, end date, amount paid and amount left. At the close, the prepaid balance in the ledger should match the schedule's total.
On January 1 Acme pays $12,000 for a year of insurance. Cash drops by $12,000 and a $12,000 prepaid appears; nothing hits the P&L yet. At the end of January $1,000 is expensed and $11,000 remains. By June 30 the balance is $6,000, and by December 31 it's gone.
Suppose Acme cancels the policy in July. If the insurer refunds the unused months, the refund comes out of the remaining prepaid. If it doesn't, whatever is left is expensed at cancellation, since there's no coverage left to use.
Prepaids are deferred revenue seen from the other side: your vendor carries a liability for the same contract. Capitalized sales commissions under ASC 340-40 follow the same logic. Every prepaid balance should have a lead schedule behind it.
Why it matters. Expense it all on day one and burn and margins swing for no real reason. Spread it, and each month carries its own cost.

The entry, worked
On January 1 Acme pays $12,000 for a year of insurance and books it as a prepaid. At the end of January, one month of coverage is used.
| Account | Debit | Credit |
|---|---|---|
| Insurance expense | $1,000.00 | |
| Prepaid insurance | $1,000.00 | |
| Total | $1,000.00 | $1,000.00 |
January carries one month of insurance, and $11,000 of coverage stays on the balance sheet.
Common questions
Do small prepayments have to be spread over the year?
Many companies set a threshold in their policy and expense small items right away. That's a policy choice, so write it down and apply it the same way every time.
Is a security deposit a prepaid?
No. A refundable deposit is also an asset, but nothing gets used up, so it isn't expensed over time. It stays on the books until you get it back.
What's the difference between a prepaid and an accrued expense?
They're opposite timings. A prepaid is paid before you use it, so it's an asset. An accrued expense is used before you pay it, so it's a liability. Both exist so the cost lands in the month you use the thing.
