A company's controller estimated bad debt expense using the percentage of accounts receivable method. Total sales for the year were $1,500,000. The ending balance in accounts receivable was $300,000. An examination of the outstanding accounts at the end of the year indicates that approximately 7% of these accounts will ultimately prove to be uncollectible. Before any adjustment, the balance in the allowance for bad debts is $4,000 (credit). Total accounts written off as uncollectible during the year were $15,000.

I'm looking for a journal entry for the year, with a breakdown of calculations. For bad debt expense.

Thank you for your time.
