Installment sales involve transactions where goods are sold, and payment is received in a series of future installments rather than a single upfront amount. This sales method is common for high-value items, such as real estate, vehicles, and large equipment, where the buyer’s ability to pay over time is an important factor. Accounting for installment sales addresses the recognition of revenue, profit, and related receivables in accordance with the uncertainty of cash collection.
Installment Method: Revenue and Profit Recognition
The installment method recognizes revenue and profit proportionally as cash is collected, rather than at the point of sale. This method is used when collectibility of the receivable is not reasonably assured at the time of sale.
Key features:
Gross profit is recognized in proportion to the cash received.
Each cash collection is split between cost recovery and profit.
Calculation of Gross Profit Percentage
Gross profit percentage is calculated at the time of sale and is applied to each cash collection.
Formula:
Gross Profit % = (Sales – Cost of Goods Sold) / Sales
Example:
Sales price: $100,000
Cost of goods sold: $70,000
Gross profit: $30,000
Gross profit %: 30%
Journal Entries for Installment Sales
At the time of sale:
Dr. Installment Accounts Receivable (total contract)
Cr. Sales
Dr. Cost of Goods Sold
Cr. Inventory
As cash is collected:
Dr. Cash
Cr. Installment Accounts Receivable
Dr. Deferred Gross Profit
Cr. Realized Gross Profit
The deferred gross profit account tracks the portion of profit not yet recognized.
Recognition of Profit as Cash Is Received
For each installment received, apply the gross profit percentage to determine the realized gross profit.
Example:
Cash collected in year: $40,000
Gross profit realized: $40,000 × 30% = $12,000
Deferred gross profit reduced by $12,000; realized gross profit reported on the income statement.
Installment Method vs. Cost Recovery Method
Installment method: Recognizes profit in proportion to cash collections.
Cost recovery method: No profit is recognized until all costs have been recovered; used when even greater uncertainty exists.
Disclosure Requirements
Companies using the installment method must disclose:
Total amount of installment receivables outstanding
Amount of deferred gross profit
Methods and assumptions used for revenue recognition
Transition under ASC 606 and IFRS 15
Current standards (ASC 606 and IFRS 15) require revenue recognition based on the transfer of control, but the installment method remains relevant in situations where collection is highly uncertain and variable consideration constraints apply.
Relevant Accounting Standards
US GAAP: ASC 606 – Revenue from Contracts with Customers (installment method, legacy guidance in ASC 605-10-S99)
IFRS: IFRS 15 – Revenue from Contracts with Customers
Summary Table: Installment Sales Accounting
Stage | Journal Entry | Financial Impact |
At sale | Dr. Receivable / Cr. Sales | Increases receivables and sales |
As cash is collected | Dr. Cash / Cr. Receivable | Increases cash, decreases receivable |
Profit recognition | Dr. Deferred GP / Cr. Realized GP | Moves profit to income statement |
