Using an improper estimate in accounting could lead to which type of error?

The use of an improper estimate in accounting can indeed lead to a variety of errors, including incorrect accrued revenue, misclassification of expenses, and the overstatement or understatement of assets.

When an estimate is used in accounting, it can affect financial statements significantly. For instance, if the estimated accrued revenue is too high, it can mislead stakeholders about the company’s actual income and performance, creating an incorrect picture of profitability. Similarly, misclassification of expenses can arise when estimates are inaccurately applied, leading to expenses being categorized inappropriately, which can distort financial results and impact decision-making.

Moreover, assets might be over or understated depending on the estimates made. For example, if a company estimates the useful life of an asset incorrectly, it may depreciate that asset too quickly (understating assets) or too slowly (overstating assets), thus affecting the balance sheet and overall financial position.

Since each of these outcomes is a direct result of relying on improper estimates, choosing the option that encompasses all these possibilities is the most comprehensive and accurate answer.
