Bitcoin Fees

[Rob768]

Can someone explain the fees to me?  If someone sends me .0001 BTC what is the fee charged?  How about .01 Bitcoin?

0,0001 fees when transfer more than 2000mBTC
0,0002 fees when transfer less than that...

for my experience (with bitcoin-QT only).

You can choose how much to send yourself.

148*I + 34*O + 10

where I is the number of inputs and O is the number of outputs. The actual size will vary by I bytes since an extra byte is prefixed to an address that starts with 0x80.

The transaction fee is for each KByte of the transaction, so you should be safe by using 0.0001 BTC per KByte as the fee. Note that the transaction size is rounded up to the next Kbyte. So a 1001-byte transaction will be charged two transaction fees.

most transactions will be well under 10kB

if your outputs are over 0.01 its going to be free

and the larger the transaction the higher priority it will get

if an output is less than 0.01 BTC use 0.0001 BTC per kB rounding up to nearest kB

What happens with the fees are they just added to the 25BTC rewarded to the miner?
