Title: PPS calculation? Post by: itmiller on June 05, 2013, 11:15:05 PM Please help. I'm trying to understand how to calculate a realistic expected income from bitcoin mining with a pool using PPS.
Let's say I had 216 Ghash/s and I'm using BTCGuid for my pool Are the following calculations correct??? (1 / Network Difficulty * 25) - Pool Fee (7.5%) 0.0000020570355057 PPS based on 12153412 difficulty 0.0000001542776629 minus pool fee 0.0000019027578428 PPS rate (matches the pool's website) I read that on average, one share will be found for every 2^32, or 4.295 billion, hashes calculated. So at 1 MHash/s, you will find a share on average every 72 minutes. so 3000 per minute at 216 Ghash/s ??? would be 180000 per hour about 4320000 per day thus 8.219913881 revenue per day??? (doesn't seem right) 246.5974164 per month 2959.168997 per year It doesn't look right to me. When I put in 216 Ghash/s on several free calculators online I get crazy returns. What am I doing wrong? Thank you for your help! I appreciate your time. Title: Re: PPS calculation? Post by: mirek on June 14, 2013, 06:55:59 PM Actually there is thread about mining or investing instead:

The calculation above is pretty simple but I don't know if I'm doing it correctly. Have a good one! Title: Re: PPS calculation?

Thank you for your help! I appreciate your time. Just keep in mind that the 'per month' and especially the 'per year' numbers are not realistic due to the skyrocketing difficulty right now.

For instance I can assume that 7950 card makes 500 MH/s, that gives me 48.98$ per month with rate below 100$ per Bitcoin (following calculator). If no costs are taken under consideration I can get my money back for the card in 7-8 months. |
