 For the convenience of customers , Delhi Metro commuters have three choices for ticket purchase . The RFID tokens are valid only for a single journey on the day of purchase and the value depends on the distance travelled , with fares for a single journey ranging from ₹ 8 ( 12 ¢ US ) to ₹ 30 ( 45 ¢ US ) . Fares are calculated based on the origin and destination stations using a fare chart . A common ticketing facility for commuters travelling on Delhi Transport Corporation ( DTC ) buses and the Metro was introduced in 2011 . Travel cards are available for longer durations and are most convenient for frequent commuters . They are valid for one year from the date of purchase or the date of last recharge , and are available in denominations of ₹ 200 ( US $ 3 @.@ 00 ) to ₹ 1 @,@ 000 ( US $ 14 @.@ 90 ) . A 10 % discount is given on all travel made on it . A deposit of ₹ 50 ( 74 ¢ US ) needs to be made to buy a new card which is refundable on the return of the card any time before its expiry if the card is not physically damaged . Tourist cards can be used for unlimited travel on the Delhi Metro network over short periods of time . There are two kinds of tourist cards valid for one and three days respectively . The cost of a one @-@ day card is ₹ 150 ( US $ 2 @.@ 20 ) and that of a three @-@ day card is ₹ 300 ( US $ 4 @.@ 50 ) , besides a refundable deposit of ₹ 50 ( 74 ¢ US ) that must be paid at the time of purchasing the card . According to new regime , the maximum permissible time limit for stay within the Metro system – 170 minutes at present – will now be 180 minutes for those buying tickets of Rs . 23 or above , 100 minutes for tickets costing Rs . 19 – 23 , and 65 minutes for tickets up to Rs . 18 .
