What is the correct double entry for acquiring a new non-current asset?

Acquiring a new non-current asset involves a direct transaction where the asset is recognized on the balance sheet, and a corresponding entry is made to reflect the payment method. When you acquire a non-current asset, the cost of the asset must be recorded, which is why you debit the 'At cost' account. This represents an increase in the asset on the balance sheet.

The credit entry typically reflects how the asset was financed. If the acquisition was funded through a cash payment, the bank account would be credited, indicating a reduction in cash. Thus, when you debit the 'At cost' account and credit the bank, you are accurately recording the increase in your assets through the purchase of the non-current asset while simultaneously acknowledging the outflow of cash from your bank account.

This approach highlights the fundamental accounting principle of duality, where every transaction has equal and opposite effects in at least two different accounts, ensuring that the accounting equation remains in balance.
