Transaction fees are really a function of transaction size in bytes not per transaction. Adding an additional input address increases transaction size by 180 bytes. The output address and other common overhead is around 44 bytes. The current minimum cost of block space is 0.0000001 BTC per byte if you are willing to wait several hours for your transaction to confirm. At that rate adding an additional input will cost you 0.0000180 so anything less than that is not worth moving under current conditions. To be confirmed in a timely fashion you need to pay a per byte fee of about 5x so in reality amounts under 0.00009 are currently not worth spending.
