How accurate are online mining calculators?

[Yoqurt1]

I have access to around 180hz of processing power from 6 gpus, and i was curious if the online calculators were reliable.

Not enough! As far as I have seen, the submitted hashrate values can never be equal to the accepted hash power. Take nanopool, you calculated hashrate will fluctuate no matter what. In that case, I take the 6 hours average and use the value for online calculators.

180Hz is above gamma, must be a lot. Seriously, 180 of what? If that's 180 MH and we're talking about Ethereum, then the online calculators are pretty reliable — ETH is a huge coin with steady network hashrate, there are no large diff swings during the day and so you'll usually get what the calc is showing you. If we're talking about something else then I demand explanations!!

Whattomine is very accurate if the pool is not scamming you. Friend of mine is a miner and he said, some pools are honest and some pools are not, so i guess you will have to try them all and see which ones are scamming you.

The calculated revenues and expenses based on hashrates are pretty accurate. I'd say up to even about 95% accuracy. However, what people usually fail to account for is the variation in their actual GPU hash rate. GPUs are not created equal and should be individually analyzed because hash rate per card, even if they come from the same manufacturer, can vary. For example one sapphire rx 470 will hash at 24 MH while another sapphire rx 470 will hash at 28 MH (because of difference in memory type).
