Before using Affirm, be sure to understand credit scoring ramifications. Affirm discloses installment account activity (opening of accounts and payments) "could" be reported to credit agencies. However, the company doesn't reveal just how much credit scoring is impacted. I purchased items via Amazon and didn't want to pay by debit or credit card. I opened two Affirm installment accounts for a total of $415. Once Affirm reported the installment accounts to the credit reporting agencies, my score dropped 27 points. Yes, you read correctly -- 27 POINTS. I would've been better off paying for the purchases by credit card, which would've caused perhaps a 2- to 4-point hit to my score. I've worked for years to pay off bills and achieve a "very good" credit rating. However, because I opened Affirm installment accounts, my rating took a substantial hit -- FOR $415. For those who wish to use Affirm, I'd advise establishing a low-dollar installment plan, preferably below $100, or, better yet, just simply use a debit card or a credit card.
