Adjusting entries Updated November 2026

Prepaid expense adjustment

A prepaid expense is recorded as an asset when paid (Dr Prepaid Insurance / Cr Cash). At the end of each period an adjusting entry moves the part that has been used up to expense: debit the expense and credit the prepaid asset for the amount expired.

Syntax

Dr Insurance Expense (or Rent Expense, Supplies Expense) / Cr Prepaid Insurance (or Prepaid Rent, Supplies)
PartWhat it is
Prepaid Insurance / Prepaid RentAsset debited when the payment is made, credited each period as coverage or occupancy expires.
SuppliesAsset for supplies bought; the adjustment moves the amount used (purchased minus on hand) to expense.
Insurance Expense / Rent Expense / Supplies ExpenseExpense debited for the portion consumed in the period.

Examples

Jan 1: Dr Prepaid Insurance 2,400 / Cr Cash 2,400; Jan 31 adjust: Dr Insurance Expense 200 / Cr Prepaid Insurance 200

Result: Expense 200 for January, prepaid balance 2,200 remaining

A 12-month policy costs 2,400, so 200 expires each month.

Dr Rent Expense 1,500 / Cr Prepaid Rent 1,500

Result: Expense up 1,500, assets down 1,500

Three months of rent (4,500) paid in advance; one month has passed.

Dr Supplies Expense 600 / Cr Supplies 600

Result: Expense 600, Supplies asset down to 300

Supplies bought during the year 900; count at year end shows 300 on hand, so 600 were used.

Common mistakes

  • Expensing the whole prepayment on the day it is paid: only the portion that applies to the current period is expense; the rest is an asset.
  • Crediting the supplies account for the amount on hand instead of the amount used: the adjustment is purchases minus the physical count.
  • Skipping the adjustment at month end: without it expenses are understated and assets overstated, so net income is too high.

Questions

Is prepaid insurance an asset or an expense?

It is a current asset when paid. It becomes Insurance Expense gradually as each month of coverage passes.

What type of adjusting entry is a prepaid expense?

A deferral: cash was paid before the expense was incurred, so the adjustment defers recognition of the expense until it is used.

How do I calculate the supplies adjustment?

Beginning supplies plus purchases minus supplies on hand at the count equals supplies used, which is the expense.
