They are very accurate based on the most current data. The problem is nobody knows what the difficulty or price of ETH is going to be in the future. The difficulty for a coin like ETH almost always goes up rather than down. Also the profit calculators assume you are mining 24/7 with no downtime and also don't take in to account things like stale/rejected shares. So it's more of a rough estimate the longer out the timeframe.
