Does any body know which "bitcoin profit calculator" are good?  Let me know thanks.

Someone in the forums just made a new one that's pretty good, check it out:
http://aleks1k.github.io/bitcoin-calculator/

I like it because it's fast, easy, and it does a good job at factoring the difficulty.

The one I've used in the past is:
http://www.bitcoinx.com/profit/

It's been fairly accurate, but doesn't forecast difficulty as good as the one at the top of the post. I've been using this calc since April 2013, right now it's only about 12% off what my mining farm is doing, so that's not bad.  The other calculators that are popular are off by 30% and up (at least for me they are).

i like this one

My favorite

Build your own spreadsheet.  Every calculator I've tried on-line is very inaccurate, and typically very optimistic.  Makes you wonder if some of them are written by the ASIC companies just to sell hardware.

Not all are accurate as they have thier own calculator it will only show you by the diff now if the diff changed too much in a month it would be diffrent .

Given that the diff changes roughly every 12 days, that's guaranteed.

I know that most of them works on same algorythm, I recomend
http://www.bitminer.pl

I personally like mining.thegenesisblock.com (http://mining.thegenesisblock.com) as you can tweak the values and most of the major manufacturers are already listed.

Easy to use and look at too.

oh yes that one works fine too!

Thanks for your reply!

Cheers!

If I'm right most of them works on same algorythm. between them there is not much difference

This.

Calculating mining profitability is rather easy for anyone not afraid of a bit of high school math. The thing that matters the most is what parameters you use, especially for difficulty increase. Many online calculators may use some pre-set value that, while user-changeable, most people don't adjust. Often this value is rather inaccurate, giving bad results.

Before you search for a calculator, make sure you have a good idea of what you expect the difficulty to do in the future.

Calculators like bitcoinwisdom will be better than using your own equation because it calculates based on difficulty change(some use monthly %).  You could write your own equation to do the same but I think bitcoinwisdom basically has it down.

With that said I would like to remind OP that historically every single calculator has been wrong and not by a small amount. Bitcoin difficulty is impossible to predict so it is important to remember that it is a gamble not an investment.

yeah well. generally as we know calculators do not calculate accurate at all...

:) you can never be sure how much you will earn.. it is like (almost) impossible.


Kind regards!

I know that the price of BTC is volatile, but is there a calc the factors in the the rate of increase in price of BTC.

Post it here when you will find it :)

I don't heard about that one.

Don't focus on price, volatility really doesn't matter when you're holding everything you mine until you're ready to sell.  Probably the only price movement you should really care about would be moving averages just to see where the trend line is heading.  Then pick a target along that trend to sell on.

A good calc should really only care about forecasting trends in hash rate so you can see what your potential earnings will be in terms of BTC.

Yes, that makes sense. I wouldn't want to sell immediately.

The Genesis Block's calculator does allow you to factor in changes in $/BTC conversion per month in case you sell your mined BTC immediately. Look for Conversion Increase / Month (%) under Conversion and Electricity

This calculator is inaccurate because difficulty changes every 2 weeks not every month.

bitcoinwisdom is the best imo. Also bitreturn.com is nice but it uses monthly % instead of biweekly.

http://thegenesisblock.com/mining/

that one is indeed very nice. But do you use it for your calculations? Is it accurate?

Does anyone know of a mining calculator that save the history of the Bitcoin difficulty to determine how well your mining has done over time?

It'd be nice to go back to some date such as October 2013 and then factor how many Bitcoins were generated since that date to today based on whatever hardware specs were entered.  I think it would be interesting to see how specific pieces of hardware have profited over time.

Thanks!

It seems like all of these, to the extent that they take difficulty increases into account, assume that the rate at which difficulty increases will remain static.  For example, on bitcoinwisdom, I can change the difficulty increase as I see fit, but it applies to all future difficulty increases.  The next increase it set to be around 12.5% according to bitcoinwisdom, but I don't think it is realistic to assume that rate will continue.  Is there any calculator available that allows you to adjust individual difficulty increases? 

I don't know what is the best but I really like this one - http://bitcoinwisdom.com/bitcoin/calculator

+1 for bitcoin wisdom :)

Yup everytime I'm tempted to buy GH at cex.io, this calculator helps me to stay away. So its worked for me for that :p

Either PBMining, CEX, or any physical miner is giving currently -50% returns on any timeframe... So is this a definitive "stay away from mining"?
Why does anyone is still with it? i dont get it...

This one is the best. The key feature is the ability to calculate slowing growth to the difficulty adjustments.
