@Tushar6. Yes, a qualifying reservation for the new host would be a reservation where the cost is at least $100 USD before cleaning fees, Airbnb service fees and taxes, if any.
In many areas this is difficult to achieve due to lower rates and I believe someone else in this forum has mentioned this. In your area, it would require a stay of 5 nights or more based on the average nightly rate charged in your area.
I would recommend that you provide feedback to Airbnb on this situation. Perhaps in India, which is a very large country, could have a different set of rules where the amount needed for a qualifying reservation is less with maybe a lower bonus paid to the referring host.
