According to latest data from June this year, the Delhi Transport Corporation (DTC), which has a fleet of nearly 4,000 buses, carries around 28 lakh passengers daily and earns Rs 1.88 crore per day.
Five days of free rides would amount to DTC losing about Rs 9.5 crore.
"This will be an added burden on us as we are already making losses," a DTC official said on the condition of anonymity.
According to CAG reports, the national capital's public transporter has been steadily making losses with no addition of new buses.
The total loss for DTC in 2014-2015 was Rs.2,917.75 crore, the highest in the previous five financial years. The operational loss of Rs 1,273.19 crore in 2014-2015 was also the highest in the previous five financial years.
Over 1,600 buses operate under the cluster bus scheme, run by the Delhi Integrated Multi Modal Agency (DIMTS), a joint venture between the Delhi government and the non-profit organisation IDFC Foundation.
Though exact figures were not available, government figures show the cluster scheme also suffered losses in 201516.
The cluster scheme buses earned Rs 283 crore as revenue in 2015-16. However, the expenditure was Rs 544.35 crore and the difference of Rs 260 crore was paid by the government.
