1) Exchange rate is instant update into calculations.
2) No body can predict the future haze rate . The calculator is using the average of the last 15 difficulty increments . that is the average difficulty changed of the last 5 months. A realistic future prediction based on past developments .
3) List all of the miners available to buy in the market. Let you adjust the delivery date to early or late  up to 90 days . it is very important to take into considerations delivery time because so far no one have deliver on time.
if you have late delivery you can adjust the delivery date to figure our your lost to ask the manufacture for compesations .
4) you input your miner cost
5) you input your miner haze rate
6) your input your electricity cost kilowatts per usd
7) Showing calculation in details . just click on the " show calculation " link

Best of all this calculation will automatic adjust to the exchange rate , difficulty level changes and default delivery date. It will update new default delivery date as manufacture announced it and let you adjust your own date to after or before the default date .
*** Every time you visit the site you should see updated calculations as new data changes. It is not like other calculators that don't adapt to change.

This calculator also let you predict how much your miner will make after certain period of time.

I like the site and I know the owner but I am not the owner. I also promote the site in my profile .
