Double-toned milk will be available at Rs. 32 per litre and milk that is not sold in packets will cost Rs. 34 a litre from tomorrow.
In a statement, Mother Dairy said it was "compelled" to raise retail prices of all variants because of an increase in milk procurement prices in the past few months.
The company said the price increase will payment to farmers at remunerative rates and sustained availability of milk. It previously raised milk prices in the Delhi-NCR region in October 2013.
Mother Dairy said close to 80 per cent of the total sale proceeds goes into procurement of milk.
Higher milk prices could have an impact on food inflation and wholesale price index inflation, which stood at 13.68 per cent and 6.16 per cent, respectively, in December.
Mother Dairy sells about 30 lakh litres of milk a day in Delhi-NCR. Last week, the company had hiked milk prices by Rs. 2 a litre in Mumbai.
Mother Dairy also sells milk in cities such as Lucknow, Kanpur and Pune.
