Simply put, paying the minimum each month could cost you a lot of money and take forever to pay off. Say you have a credit card with a $1,000 balance and a 14.95 percent interest rate. According to Credit Karma’s debt repayment calculator, if you only paid $25 a month, it could cost you an estimated $393 in interest and take you an astonishing 56 months to pay off.
Generally, negative credit records, such as collection accounts, bankruptcies and late payments, will remain on your credit reports for seven to ten- years. Paying off the account sooner doesn't mean it’s deleted from your credit report, but listed as “paid.” Of course, it’s smart to pay your debts, but expect the major change in your report to come after negative records expire.

Credit scores are three-digit numbers created using the information in credit reports. That information is used to try to predict how likely you are to pay your bills on time.  While you have only three credit reports (at least from the major, national agencies), there are many different types of credit scores that can be calculated based on your credit information.
Credit scoring is used throughout the credit industry in South Africa, with the likes of banks, micro-lenders, clothing retailers, furniture retailers, specialized lenders and insurers all using credit scores. Currently all four retail credit bureau offer credit bureau scores. The data stored by the credit bureaus include both positive and negative data, increasing the predictive power of the individual scores. TransUnion (formerly ITC) offer the Empirica Score which is, as of mid-2010, in its 4th generation. The Empirica score is segmented into two suites: the account origination (AO) and account management (AM). Experian South Africa likewise has a Delphi credit score with their fourth generation about to be released (late 2010). In 2011, Compuscan released Compuscore ABC, a scoring suite which predicts the probability of customer default throughout the credit life cycle. Six years later, Compuscan introduced Compuscore PSY, a 3-digit psychometric-based credit bureau score used by lenders to make informed lending decisions on thin files or marginal declines.[16]
Establish new credit – If you’ve filed bankruptcy or have serious delinquencies, the best way to rebuild your score is to jump right back in and establish new credit. But this time you have to manage your accounts more responsibly. Make your payments on time and don’t use up more than 20% of the available credit limits on your credit cards. If you can do this then your scores will increase much faster than simply waiting for your delinquencies to fall off your reports.
A: You need to provide your name, address, Social Security number, and date of birth. If you have moved in the last two years, you may have to provide your previous address. To maintain the security of your file, each nationwide credit reporting company may ask you for some information that only you would know, like the amount of your monthly mortgage payment. Each company may ask you for different information because the information each has in your file may come from different sources.
