Hashflare profitability table/charts for 220$ contracts

Based on the following formula now you can find out the exact BTC/US$ rate that Hashflare is calculating its fees with:

US$ = 0,0035 * (Total Hashrate in GH/s / 10) / Maintenance Fee (in Satoshi) * 100.000.000
Short:
US$ = 35.000.000 * Your TH/s * Maintenance Fee (in Satoshi)

You know your hashrate and you know your Maintenance fees according to your history.
So, here's an example for today with a hashrate of 1 TH/s:
US$ = 0,0035 * (1000 / 10) / 2.482 * 100.000.000 = 14.101.53$ Short:
US$ = 35.000.000 * 1 / 2.482 = 14101,53$

Note: I'm using the european standard (the "." is just decimal mark, not a comma!)

According to that formula I can calulate all the fancy numbers and charts in my Google table more exactly.
And here is a table for Hashflare beginners who started in the last few days with 1 TH/s for 220 US$ without any discount:

Have a look at the charts on the second spreadsheet!

As you can see the PBP (pay back period) is 124 days for BTC atm. That's not too shabby!
The PBP in dollars is 157 days now, but it hopefully will drop as soon as the BTC rises again.
Feel free to record your own numbers to understand all the numbers Hashflare is offering you.

If you are logged in (with your Google account) you can get a copy of that table and use it on your own! Or just download it to edit it with Excel, if you like that more.
