If I pay off my credit cards how much will my score go up.

I have two credit cards that need to be paid off. The amount is about 700 dollars. How long will it take for my credit score to go up after I pay those off?
-----------------------
30 days or less if they are maxed and at least 1 year old
-------------------------
Do you know how many points it will increase? If its about 2 cc with about 400 each.
Thanks. Those are the only bad cc I have on my credit and they messed up my credit. I had some other ones on my credit report about 3 years ago, but I paid them off.
----------------------
I don't know your score now.
Do you?
Do you have 3 open lines of credit now, that are at least 1-2 years old and with no late payments in the 1-2 year period?
---------------------
My score now for TransUnion is 579, experian 548 and equifax is 579. I still have 2 credit cards that I need to pay on which I am going to do this month. I have a car loan that I pay on I had one late payment. I have a store card that I always pay on time, and a student loan that I will start paying soon. The 2 credit Cards I think are killing me. One is capital one and one is a store charge card. I called to pay them off, and they told me they were going bankrupt so now they are trying to collect.
--------------------------
Pay any collection or charge off after negotiation. Reopen same accounts if possible buy sending in up front payment so they trust you. Make sure the report to bureaus.You need three open reported lines of credit
Make sure balances are less than 80% of limit.
Close capital one and get another card here.
Credit Cards for new good credit
Make on time payments for 1 to 2 years and your score will go to 700

Thank you so much! I have one more question for now. If I try to open one of these credit cards at credit.com will it take away from my credit that I do have?
-------------------------
No it will not.
