The wholesale price index's (WPI) annual rise compared with a 4.99 percent jump forecast by economists in a Reuters poll. In January, wholesale prices, long seen as India's main inflation measure, rose 5.05 per cent.
The reading for December WPI inflation was revised to 6.40 per cent from 6.16 per cent earlier.
Food prices rose 8.12 per cent year-on-year last month, slower than an annual rise of 8.80 per cent in January.
Cooling food prices helped slow down retail inflation for a third straight month to a 25-month low of 8.10 percent in February, data showed on Wednesday.
