The difference between total revenue and total expenditure of the government is termed as fiscal deficit. It is an indication of the total borrowings needed by the government. While calculating the total revenue, borrowings are not included. Generally fiscal deficit takes place due to either revenue deficit or a major hike in capital expenditure. Capital expenditure is incurred to create long-term assets such as factories, buildings and other development. A deficit is usually financed through borrowing from either the central bank of the country or raising money from capital markets by issuing different instruments like treasury bills and bonds.

A mismatch in the expected revenue and expenditure can result in revenue deficit. Revenue deficit arises when the government’s actual net receipts is lower than the projected receipts. On the contrary, if the actual receipts are higher than expected one, it is termed as revenue surplus. A revenue deficit does not mean actual loss of revenue. Let’s take a hypothetical example, if a country expects a revenue receipt of Rs 100 and expenditure worth Rs 75, it can result in net revenue of Rs 25. But the actual revenue of Rs 90 is realised and expenditure is Rs 70. This translates into net revenue of Rs 20, which is Rs 5 lesser than the budgeted net revenue and called as revenue deficit.
