Understanding Transaction Fees, Outputs, and Change (Simplified)

A Bitcoin transaction must obey a simple rule: Total Input ≥ Total Output.

1.

Outputs:

The amounts you send to recipients plus any change sent back to yourself.
2.

Fee:

The miner fee is the difference left over: Fee = Total Inputs - Total Outputs
3.

Example:

Input: 0.10000000 BTC
Send to recipient: -0.01000000 BTC
Return as change: -0.08950000 BTC
──────────────────────────────
Miner Fee: = 0.00050000 BTC

In short:

In short: You cannot create bitcoins. The total inputs must fund all outputs (to recipients and yourself) plus the miner fee.

⚠️ Crucial Warning:

If you do not explicitly specify a change output back to your own address, the entire leftover amount will be given to the miner as an unexpectedly large fee. Always ensure your transaction includes a change output to yourself, unless you intentionally want to overpay.

About Replace-by-Fee (RBF):

This optional flag allows you to replace an unconfirmed transaction with a new version that has a higher fee, speeding up confirmation. Transaction replacement Bitcoin Wiki

input	output hash	Hash of the transaction containing the output we're spending. Reversed automatically.
	output index	decimal Number transactions. There can be several outputs in the referenced transaction, this identifies which of those outputs we're using (counting from zero). For example 2 = 02000000 (hex and reverse)
	script length	--- For example: ScriptSig 216 length: 108 bytes, '6c' in hex
	scriptSig	ScriptSig size \| ScriptSig \| Hash type \| length bytes \| Public key
	address
	amount	satoshi (BTC: 0.00000000, 0.00$) Total balance. For Segwit addresses only. To sign a transaction in offline mode, please specify the full amount of the transaction input.
	sequence	This transaction supports the Replace-By-Fee (RBF) function, which allows you to increase the commission.

⚠️ does not automatically create change outputs, so you can easily accidentally pay a large transaction fee. Create a multi-output transaction so you can send change to yourself.
