The half-year mark

[vanillabean]

You got an inquiry, a credit card and an installment loan, and it's now half a year later. Supposedly the impact of new credit has mostly worn off, but how do the three compare?

Different impacts on different categories....

As for new credit only, the major impact of a new account is usually not the inquiry, but rather the impact on reduced AAoA due to the addition of a new account, with initial age of zero, and thereafter only an age from its date opened.  That impact on AAoA is the same, regardless of the type of account. So no diff. there.

As for util of credit, revolving % util on the CC is scored at a much higher weighting than the % remaining of unpaid balance on an installment loan.

So for util scoring, the balance on the CC will have a much greater impact than the remaining balance on the loan.  It depends on how you use the CC.

RobertEG, thanks for your clarification, which inspired further thoughts and digging. In particular I was looking for weight and duration.

By weight I mean if a new credit card minus the impact of lower AAoA weighs more or less than an inquiry. But duration I mean how soon the "FICO score ingredient" "Amount of new credit" under "FICO Score Summary" in a FICO score report moves up one step, say from "good" to "very good".

I have noticed that a new credit card alone (no inquiry) can go from good to very good in 6 months, while a new inquiry may be unchanged as good (EQ) / not good (TU) in 6 months. (I come to recall hauling once pointing out, I think, very good not until no inquiries, so at the one-year mark.)
