New mining calculator with growth consideration

[knatsch]

Hello together,
This may be not the right place, but since I am considered a newbie, I have to post it here.
Like many of us, I spent some time lately with Bitcoins. Unfortunately, I could not find a suitable
calculator that gives results in regard to the strong ascending difficult. Current calculators almost let me believe
that mining could pay off not bought hardware within a few weeks. In reality, this seems to be no longer the case since the difficulty is growing in high rates lately.
That is why I programmed a calculator for myself. I believe that the result is quite nice so I thought,
why not simply host it publically. You guys might like it too

Try it out and let me know what you think!

Sounds great; I'd been looking for something similar.

Unfortunately, your site seems to be down for me

Not sure people will want to see the results of this... 

Guess I will be able to play WoW at the settings in a few months though

This is a killer calculator, more useful then http://www.alloscomp.com/bitcoin/calculator.php

Thanks!

Wow this is a great calculator, I've always been interested to see growth as a factor!

I just updated the calculator. The difficulty is no longer changed every 10 days. Instead, the exact day is derived from the growth factor which should give an even more accurate result.

Great tool, thanks!

I have no idea how to use it lol...

How do I know what the growth is?

Yeah this is awesome stuff this would have saved me hours of tedious calculations. Nice job with the graphs (Bookmarked!)
I have one thought, tho the percentage is kind of confusing, Might I recommend just being able to type in 45 instead of 1.45?

Definitely a good choice.  I think the remaining issue is that the difficulty probably can't be modeled as a geometric series.  That is, although the last increase was ~16%, the one before that was like 80%, and the next one may be <10%.  I'm not sure how you could take that into account.

Also, there appears to be a bug if you put a large number in the Growth field.  For example, if you put 5 (500%) in, it gives you a larger number of BTC than if you put in 4 (400%).  You may be overflowing somewhere.

Found a 0 division bug. I was hoping that difficulty would never raise  

EDIT: Nevermind. I misread the description. I should type 1 if I don't want the difficulty to raise. The bug still exists though...

AFAIK the best way is to look at the graphs at http://bitcoin.sipa.be/ to get an idea.

The way it is done now indicates more clearly that you can enter values like 0.xx to simulate a negative growth. You might be right though, people could also enter the growth with a leading '-'. Since the calculator is now online for a few weeks it might not be such a good idea to change the input format afterwards, as it confuses the users.

Yes I am quite aware of this issue but I also see no way of simulating this. By analyzing the graphs at http://bitcoin.sipa.be/ you could take the growth over a greater period as input to get more accurate results but of course this is just another approximation.

Thanks for this hint, I actually introduced a stupid math bug this morning  Should be fixed now.

Yes you got it, just enter '1' into the growth field. Thanks for noticing the division bug, it is now checking for unwanted 0's in the input fields.

Thanks for the calc! Works great

It's kind of harsh to see this. I'm just kind of glad I bought a card for gaming, that is also decent for mining. Thus, I haven't spent anything but power on mining so far. When I fall behind even, I guess I'll give it a quits and just trade in BTC.

Thanks for the calculator. Hopefully this will deter some people from being stupid.

Post your address; I wouldn't mind sending you a small tip.

Thanks, interesting. Would love to sneak into the source code
