Many factors effect the point value of a charge off and none of us can guess without a full credit profile that includes more than just a score. The point value of a charge off will be more if you have a higher score. Similarly, the more charge offs you have likely the less effect of any individual charge off. Someone with an 800 score could lose a lot more than 100 points on a single charge off and removing that charge off could shoot their score back to the 800s. Someone with a low 600 score likely won't be hurt too much by a charge off, but other factors come into play.
None of us know FICO's proprietary formula. None of us here have indepth access to your overall credit profile. The most anyone can do is hazard a guess that could be off by 50 or more points. The only thing I can tell you that will be of any help is that as a general rule the higher your score the more impact a single charge off will have. Conceivably, it could have more than a 200 point impact if all the factors align correctly or absolutely no impact if your credit report has a perfect storm of other existing negatives.
