Independent economists, however, do not agree, and peg it at 5.7 per cent of GDP.
The Vijay Kelkar panel report on fiscal consolidation, which the ministry is expected to put in the public domain this week, could give clarity to the issue.
At a full Planning Commission meeting on Saturday, Finance Minister P Chidambaram had said major subsidies would be 2.4 per cent of GDP, against the 1.9 per cent projected in the Budget.
At 1.9 per cent, it was estimated to decline from Rs 216,297 crore (Rs 2,162.97 billion) in the revised estimates of 2010-11 to Rs 1,90,015 crore (Rs 1,900.15 billion) in the Budget estimates for 2012-13.
However, if subsidies rise to 2.4 per cent of GDP, the number would be Rs 243,837 crore (Rs 2,438.37 billion).
The net effect will be that the fiscal deficit rises to Rs 5.6 lakh crore (Rs 5.6 trillion) against the estimated Rs 5.1 lakh crore (Rs 5.1 trillion), assuming the revenue side of the Budget behaves the way detailed in the document.
At this level, the fiscal deficit turns out to be close to 5.5 per cent of estimated GDP (Rs 101 lakh crore or Rs 101 trillion).
However, the ministry is confident of curtailing this to 5.3 per cent of GDP, as the disinvestment target could be raised, some more could come from dividends by public sector entities, while non-plan expenditure will be curtailed.
Officials said oil subsidies will be more than projected and the additional amount will be provided in the second supplementary budget.
Despite the latest fuel price moves, oil marketing companies are complaining of Rs 1.67 lakh crore (Rs 1.67 trillion) of under-recoveries.
About 40 per cent of it could come from upstream oil companies, which will leave the government with a subsidy burden of Rs 1 lakh crore (Rs 1 trillion).
This will be in addition to the Rs 43,580 crore (Rs 435.8 billion) already listed for the OMCs for this year but used for meeting the under-recoveries of 2011-12.
