The Gadgil Formula was the standardized mechanism used to determine the allocation of Central Assistance for State Plans in India. Named after Dr. D.R. Gadgil, the then Deputy Chairman of the Planning Commission, it was first adopted in 1969 for the Fourth Five-Year Plan. Prior to this formula, there was no objective criterion, and allocations were largely discretionary, leading to allegations of political favoritism and regional imbalance.
Core Objective and Constitutional Context
The primary objective of the formula was to ensure “Evolutionary Federalism” by distributing central resources in a transparent, objective, and equitable manner. While the Finance Commission (under Article 280) handled the distribution of tax revenues, the Planning Commission used the Gadgil Formula to distribute “Plan Assistance” (grants and loans) under Article 282 of the Constitution.
The Original Gadgil Formula (1969)
The original version of the formula established specific weightages for the distribution of pool funds among the states. The criteria were as follows:
- Population (60%): Based on the 1971 Census to ensure that larger population bases received adequate support.
- Per Capita Income (10%): Distributed only to states with per capita income below the national average to promote equity.
- Tax Effort (10%): To reward states that showed efficiency in their own tax collection.
- On-going Irrigation and Power Projects (10%): To ensure that massive infrastructure projects were not stalled due to lack of funds.
- Special Problems (10%): Discretionary weightage for states facing unique challenges like chronic droughts, floods, or tribal area development.
The Modified Gadgil-Mukherjee Formula (1991)
In 1991, following the recommendations of Pranab Mukherjee, the formula was revised to make it more performance-oriented and responsive to the needs of the states. This version remained in use until the dissolution of the Planning Commission.
| Criteria | Weightage (%) | Explanation |
|---|---|---|
| Population | 60% | Continued use of the 1971 Census to encourage population control measures in later years. |
| Per Capita Income | 25% | Divided into two: 20% for states below the national average and 5% for all states based on the distance method. |
| Performance | 7.5% | Includes Tax Effort, Fiscal Management, and progress in National Priorities (Population control, Literacy, Land Reforms). |
| Special Problems | 7.5% | Provided for states with geographical or socio-economic handicaps. |

Classification of States: Special Category Status (SCS)
The Gadgil Formula introduced the distinction between General Category States and Special Category States (SCS) for fund allocation.
- Special Category States: Includes the North-Eastern states, Jammu & Kashmir (now UTs), Himachal Pradesh, and Uttarakhand. These states received 30% of the total central assistance pool first.
- Grant-Loan Ratio: For SCS, the assistance was provided as 90% Grant and 10% Loan. For General Category States, it was 30% Grant and 70% Loan.
- Funding Priority: SCS have low resource bases and difficult terrain, necessitating higher central dependency.
Significance in Indian Economic Planning
- Reduction of Discretionary Power: It limited the Union Government’s ability to use plan funds as a political tool against opposition-ruled states.
- Fiscal Discipline: By including “Fiscal Management” in the performance criteria, it incentivized states to keep their fiscal deficits under control.
- Regional Parity: The high weightage for population and low per capita income ensured that backward states like Bihar, Uttar Pradesh, and Odisha received a larger share of the resource pie.
Critical Limitations
- 1971 Census Freeze: Critics argued that using the 1971 census for decades penalized states that successfully implemented family planning (primarily Southern states).
- Inadequacy for Urbanization: The formula was heavily biased toward rural and agricultural parameters, often overlooking the massive infrastructure needs of rapidly urbanizing states.
- Debt Trap: For General Category states, the 70% loan component often led to a mounting debt-servicing burden, limiting their future developmental spending.
Transition to the Current Regime
Following the replacement of the Planning Commission by NITI Aayog in 2015, the Gadgil-Mukherjee Formula was discontinued.
- Central Assistance: The distinction between Plan and Non-Plan expenditure was abolished.
- Finance Commission Dominance: Resource transfer is now primarily governed by the recommendations of the Finance Commission (the 14th and 15th FCs significantly increased the vertical devolution to 42% and 41% respectively).
- Centrally Sponsored Schemes (CSS): Funds are now routed through specific schemes with fixed cost-sharing ratios (e.g., 60:40 or 90:10) rather than a block formula.
Fact File for UPSC Prelims
- Entry 20, List III: Economic and Social Planning is a Concurrent List subject, providing the legal basis for the Centre to allocate funds for State plans.
- NDC Role: The National Development Council was the body that officially approved the Gadgil Formula and its subsequent modifications.
- Article 282: Known as “Discretionary Grants,” this was the constitutional vehicle for Gadgil Formula transfers, distinguished from the statutory grants under Article 275.
- SCS Status Today: While the 14th Finance Commission effectively removed the “Special Category Status” for new states, the existing 11 states continue to receive benefits under the old 90:10 ratio for Centrally Sponsored Schemes.
