Fiscal deficit measures the gap between the money a government spends and the money it receives through taxes, fees, dividends, and other sources, excluding borrowings.

When government expenditure exceeds its available receipts, the government generally needs to borrow money to finance the difference.

Fiscal Deficit Formula

Fiscal Deficit = Total Government Expenditure − Total Receipts (Excluding Borrowings)

Government expenditure includes:

• Infrastructure development
• Healthcare and education
• Defence expenditure
• Salaries and pensions
• Subsidies and welfare programmes
• Interest payments on existing debt

Government receipts include tax revenue, non-tax revenue, and non-debt capital receipts such as disinvestment proceeds and recovery of loans.

For example, suppose the Government of India has:

• Total expenditure: ₹50 lakh crore
• Total receipts excluding borrowings: ₹35 lakh crore

The fiscal deficit would be:

₹50 lakh crore − ₹35 lakh crore = ₹15 lakh crore

The government must finance this gap, primarily through borrowing.

Fiscal deficit is commonly expressed as a percentage of GDP.

Fiscal Deficit (% of GDP) = (Fiscal Deficit ÷ GDP) × 100

If GDP is ₹300 lakh crore, a fiscal deficit of ₹15 lakh crore equals 5% of GDP.

A fiscal deficit can support economic development when borrowed funds finance productive infrastructure and essential public services.

However, persistently large deficits may increase government debt, interest payments, and pressure on public finances.

Financing Government Infrastructure Expenditure

Suppose the Government of India plans additional spending on highways, railways, healthcare, and education.

Its estimated financial position for the year is:

• Total expenditure: ₹48 lakh crore
• Total receipts excluding borrowings: ₹36 lakh crore

The resulting fiscal deficit is:

₹48 lakh crore − ₹36 lakh crore = ₹12 lakh crore

To finance this gap, the government issues securities such as Government Securities (G-Secs) and Treasury Bills.

Banks, insurance companies, mutual funds, and other investors purchase these securities, providing funds to the government.

The borrowed money helps finance public expenditure, including infrastructure projects that may improve productivity and support economic growth.

However, the government must also pay interest on the borrowed funds and repay the securities when they mature.

This demonstrates how a fiscal deficit enables government spending beyond current receipts while creating borrowing and debt-servicing obligations.
