Prepaid expense in accounting: an advance payment recorded as an asset and recognized as expense over time.
A prepaid expense is an advance payment for goods or services that will benefit future accounting periods. Because the benefit has not yet been fully consumed, the payment is recorded as an asset first and expensed later.
At the time of payment:
1Dr Prepaid Expense
2 Cr Cash
As the benefit is used up:
1Dr Expense
2 Cr Prepaid Expense
If a prepaid item is expensed immediately, current-period profit is understated and assets are understated. If it is never amortized out of the asset account, later periods are overstated instead. That is why prepaid expenses are a routine part of adjusting entries.
