"This is called the reserve. Your node will not show you the reserve as part of your balance (since you can't spend it)." This part is a bit confusing. My local balance shows 999056, but my local_chan_reserve_sat is 10000. My local balance is not missing 10k sats from capacity, only less than 1k sats.

Hmmm right. I'm wrong, the reserve appears to be part of your balance here. Maybe you just made a mistake in computing transaction fees. I'll delete my answer to not mislead anyone else.

Oh, you probably just forgot to account for the anchor output! I'll update my answer instead.

Lightning: why don't balances add up to capacity?

# Lightning: why don't balances add up to capacity?

(Asked by: username_0 on 2022-09-29)

I've created a brand new lightning channel with two nodes.

I loaded the channel with `"capacity": "1000000"`, but `"local_balance": "999056"`. I know that `"commit_fee": "614"` accounts for some reserved sats for channel closing. But that still leaves about 330 sats unaccounted for. Where are these sats visible? Thanks

You are probably missing the [anchor output](https://github.com/lightning/bolts/blob/master/03-transactions.md#to_local_anchor-and-to_remote_anchor-output-option_anchors) contained in the commitment transaction in your calculation. Its value is exactly 330 sats.
