Explainer: How Daily Revision Of Petrol, Diesel Prices Works

So, till yesterday the VAT on petrol in Delhi was Rs 15.07 while today it stands at Rs 14.54. On diesel, VAT today is Rs 8.41 per litre as against Rs 8.73 previously.

The excise duty cut paused the relentless rise in rates witnessed since July 4. While petrol prices had increased by Rs 7.8 to reach Rs 70.88 a litre in Delhi yesterday, the highest since August 2014, diesel rates had risen by Rs 5.7 to touch an all-time high of Rs 59.14.

The excise duty cut would cost the government Rs 26,000 crore in annual revenue and about Rs 13,000 crore during the remaining part of the current fiscal year that ends on March 31, 2018, the government had said yesterday.

The government, which had between November 2014 and January 2016 raised excise duty on petrol and diesel on nine occasions to take away gains arising from plummeting global oil prices, has been criticised for not cutting excise duty despite a sustained rise in fuel prices since early July.

In all, duty on petrol was hiked by Rs 11.77 per litre and that on diesel by 13.47 a litre in those 15 months that helped government's excise mop-up more than double to Rs 2,42,000 crore in 2016-17 from Rs 99,000 crore in 2014-15.

While the costliest petrol was sold in September 2013 when it was priced at Rs 76.06 a litre in Delhi, the previous highest rate for diesel was also during the BJP rule in September 2014 when it was priced at Rs 58.97 per litre.

On petrol, excise has been cut to Rs 19.48 per litre from Rs 21.48 per litre and on diesel to Rs 15.33 a litre from Rs 17.33 previously.

The rise in petrol and diesel prices also reflected in wholesale price inflation, which increased to 3.24 per cent in August 2017, as compared to 1.88 per cent in July.
