A380: 3T costs $1950
747: 2.5T costs $1625
787: 1.3T costs $845
737: 0.7T costs $455
Of course, you would have to add the extra cost of 15mins of flight time (maintenance, crew, etc) as well as any extra approach fees and the costs of any delay caused by the go-around.
About the cost caused by the delay. It can be very expensive, in specific conditions :
- The airline is based on the hub model
- The flight is supposed to land at the hub airport
- There are many passengers on board that can miss a connection
Ballpark figure is that 20 mins can cause 10 k$ loss. It can vary a huge lot of course, it's just a guestimate based on figure I saw at my airline's tool for managing delays.
A380 full of connection pax, and if the following flights cannot wait to depart (because of curfew for example), and if the hotels are all booked, it will be much much larger than a flight with local pax or pax with connecting flights that can wait.
