I was studying about EOS RAM Allocation, CPU and NET bandwith and I was wondering about how much it costs to organize a real airdrop. So I just came up with this small experiment in Jungle testnet which can be totally adapted to Mainnet, because the storage and bandwith are the same you can just adjust the current EOS and RAM prices.
It's actually super simple to Airdrop a token in EOS <3
- Create an account for your smart contract
- Download the official
eosio.tokenfrom eos repository - Compile and deploy it to your contract
- Create your token symbol and supply
- Start issuing tokens
I'm going to cover all the above steps below, let's go!

Default Account creation on Junglenet
Created account eosairdroper from http://dev.cryptolions.io/#account
Here's the initial account balance and stake stats:
$ cleos get account eosairdroper

Deploying the eosio.token contract
Simple deploy from original EOS Repo without any changes:
$ cleos set contract eosairdroper ~/eos/build/contracts/eosio.token ~/eos/build/contracts/eosio.token/eosio.token.wast ~/eos/build/contracts/eosio.token/eosio.token.abi

Yeah, the cost to deploy eosio.token is 186.335 Kb with today's version! Ok, the fun begins... Let's create a token!
Creating a token
Default token, 1 billion supply and four decimals exactly like EOS.

Neat! To create a token we spent very little resources, almost nothing...
Issuing some Tokens
Now let's airdrop some tokens!
I'm using some random accounts from the official snapshot (sorry if you are one of them):

No Memo
Testing an airdrop with no memo to another random account ge3dmgenesis: 1000.5425 EOS - it reduced from 128 bytes to 120 bytes of net bandwith usage, no significative changes in cpu and didn't affect anything on RAM, AT ALL - Remember, from the eosio.token contract we don't store the memo anywhere.

Results
If we assume the above values as an approximated average (I would need to load a batch of a couple thousands accounts to make sure), these are the stats that we will need for a full airdrop based on the official mainnet launch snapshot:
| Stat | Avg / tx | Total 163,930 Accounts |
|---|---|---|
| Net Bandwith | 128 bytes | 20.98 Mb |
| Cpu Bandwith | ~2.36 ms | 386.87 sec |
| RAM | 0.229 kb | 37,540 kb |
You will eventually want to remove some accounts like B1, exchanges and so on from the airdrop.
Also these are other interesting stats from the genesis snapshot:
| Minimum EOS Balance | Number of Accounts |
|---|---|
| 0.0000 EOS | 163,930 |
| 1.0000 EOS | 162,106 |
| 5.0000 EOS | 148,624 |
| 10.0000 EOS | 137,950 |
| 100.0000 EOS | 84,979 |
Mainnet
As of today's date, a couple hours ago we had an account creation with a RAM price of 0.015 EOS/Kb.
So if you are planning an Airdrop now, with the official genesis snapshot it would cost
around ~563 EOS, which right now translates to $6025.17 (USD). I'm not considering the net and cpu because it fully restores in 3 days, you could separate your airdrop in blocks.
My next step is to run a big batch of thousands of tokens issuing transactions so I can prove all of these stats are correct.
Also a BIG THANK YOU to @nsjames, @syedjafri and @blockliberty for the nice insights, discussions and prices! And of course to this amazing Jungle Testnet @cryptolions
