Answer Details
The concept that enables a business to determine the actual profit or loss for a particular period is the accrual concept. This concept recognizes revenue and expenses when they are earned or incurred, regardless of when the cash is actually received or paid out.
In other words, under the accrual concept, revenue is recognized when it is earned, even if the customer hasn't paid yet, and expenses are recognized when they are incurred, even if the business hasn't paid for them yet. By doing this, the business is able to more accurately match its revenue and expenses for a particular period, which allows it to determine its true profit or loss.
For example, if a business provides services in January but doesn't receive payment until February, under the accrual concept, the revenue would still be recognized in January because that's when the services were provided. Likewise, if a business incurs expenses in December but doesn't pay for them until January, under the accrual concept, the expenses would still be recognized in December because that's when they were incurred.
Overall, the accrual concept helps businesses to better understand their financial performance over a given period, and is an important tool for decision-making and planning.
