No, not really. Although there is a school of thought which says credit scores depend upon a mix of sources; credit/charge cards, installment loans, mortgage and so forth.

Installment loans IIRC (and this covers everything from mortgages to student loans) are treated slightly different for credit score purposes. This mostly stems from fact there isn't a "utilization" rate per se; that is payments are based upon sums borrowed with interest baked in, then spread over a period of time.

For example if you do a debt consolidation loan for $10k at 11% over 36 months, your monthly payments will be what they are for life of loan.

Unlike say a credit card where if you were carrying $10k where the payments are based upon balance each month subject to APR (and thus decrease as amount owed is reduced via payments), installment loan payments are same for life of loan. Only way to reduce amount owned (interest payments) is to attack the principal which when reduced decreases amount subject to interest. Some lenders make this rather easy, others not so much.

Easiest way is to make extra payments and see to it excess funds are directed to the principal. Some lenders however will take any extra funds and apply them to next payment due. This unless you specifically tell them to do otherwise...

All this being said installment loans (such as for debt consolidation) aren't a bad way to go if someone knows what they are doing and can handle things correctly.

Someone with say $15k or more of credit card debt that cannot take advantage of a decent zero percent balance transfer deal might find a debt consolidation installment loan the next best thing. This is especially true of they are in high utilization range for one or more cards.

Provided they use funds for stated intended purpose, and rate on loan is substantially lower than highest APR on credit cards a few good things come out of using an installment loan.

First with credit card balances paid off credit score in a few months will rise (providing there isn't any negative information), this even with any potential negative hit from taking out loan in first place. Free from making credit card payments that money can now be put into paying off installment loan not just on time, but making extra to get it paid off sooner.

Meanwhile having credit cards totally free of carried balances allows using the grace period as "free money". Never charging more that can be paid off in full each month again will boost credit score. If the card used has a decent cash back or other rewards that is all gravy.
