Ah I see - so the transaction fees are considered newly generated coins? In other words, they are not considered as outputs from the transaction itself?

Yes, that is correct. There are no special outputs for fees. Fees is the inplicit difference between sum of inputs and outputs.

<p>Transaction fees are not counted as newly generated coin. Here new is 50 but 04 is your total transaction fees. As a total reward it is 50.04 but newly generated only 50. </p>

<p>The block reward here is 50.04 BTC instead of 50. Why is this so? I notice many blocks have this slight excess.</p>

Why is the block reward slightly higher than what it should be?

The coinbase transaction(the transaction that pays miner bitcoins) gets bitcoins from two sources.

* Block reward: This part goes on declining like 50/25/12.5 and so-on in a pre-defined schedule
* transaction fees: This part is total sum of all transaction fees of all transactions in the that particular block. This is determined by market conditions.

Miner Income = Block-reward + Transaction fees
