How long after an account has a $0 balance will it show up on your credit report?

[AgentJackBauer]

Within the last three months I have paid 3 credit cards that I have which had a total combined balance of $3900 and now they all have a $0 balance! I also got two medical bills waived off (which they were $1700 and $300).

How long before these new $0 balances show up on my credit report and how long until my FICO scores go up since I have a $0 balance?

I have two credit cards left and I'm almost done with them!

They should show the new balance when the card companies report the updated balance to the CRA's.

To add, they usually report around the statement date. Then there are some oddballs like Amex or any HSBC product that reports on a different timetable.
