Revenue expenditure is the expenditure, the benefit of which is immediately (within one year) expended or exhausted in the process of earning revenue. For example, expenditure on purchase of goods for sale, on their movement from one place to another, on maintaining assets, on keeping a business organization going etc.
If any expenditure of a revenue nature is treated as capital, it would have the effect of inflating the profit of the year. If the expenditure of a capital nature is charged to a revenue head, the amount of profit would be reduced.
