Well, the biggest cost here wouldn't be in the app, but in the server infrastructure. As usual with connected apps, people often forget they have to be connected to servers. The app itself is just a view to what the servers provide, so it's not the major cost. 20K $ to 100K $ should be enough.
On server stuff, I expect it to be a lot more, particularly if you aim for a wide audience (several million $).
On a Whatsapp clone, I'd consider:
- solutions for performing calls through servers, not that easy. Look at what Twilio provides. WebRTC is an upcoming protocol that will ease that (web & mobile).
- solutions for API, IM and user accounts management. Look at StackMob or Parse which are MBaaS (Mobile Backend as a Service).

Hope it helps!

The actual cost for building a service like Whatsapp is mostly dependant on the infrastructure to put in place.
The price for the application (iOS client) is then only a small part of the total cost.
Without knowing the infrastructure choice you made, it is quite complicate to estimate the work load for the iOS client.
The more complex part of such a project would be to manage the message status in real-time, connect to various APIs to enable friend invites to grow the network easily or integrate with their current iOS contact book.

I wrote an article for same. Here is the link : http://www.abbacustechnologies.com/cost-to-design-and-develop-mobile-application/

So as per this research, Whatsapp could cost you between : $40k-$80k

Hope that helps!!

WhatsApp is a benchmark of all apps of recent history and is one of the most successful real time messaging apps that are available for all platforms. You can easily exchange messages between iPhone, Android, Windows Phone, BlackBerry and Nokia phones without paying for SMS. Before you start developing an app like that you first have to understand that WhatsApp is not just an app – it’s a service. Once you develop an app you have to maintain its intended functionality.

It may cost up to $100000 to $250,000 if it developed in India or somewhere like Phillippines. Cost to develop in the USA would be 5x than it in India.
