Credit Mix: Why the Types of Accounts You Hold Matter

Credit mix refers to the variety of credit account types in your credit file. FICO scoring models consider credit mix as approximately 10% of your total score, making it a smaller but still meaningful component. The underlying logic is that consumers who successfully manage multiple types of credit, including revolving accounts like credit cards and installment accounts like auto loans or mortgages, demonstrate a broader credit management capability than consumers who only have one type of account. Lenders view experience with diverse credit types as a positive signal.

The four main account types that contribute to credit mix are revolving accounts (credit cards and lines of credit), installment loans (auto loans, personal loans, student loans), mortgages, and retail or store credit accounts. Each type has a different repayment structure: revolving accounts have variable balances and flexible payments, installment loans have fixed payments and terms, and mortgages are long-term secured loans with amortisation. Demonstrating competent management of more than one type builds a stronger credit narrative.

Which Account Types Add the Most to Credit Mix?

Mortgages are generally the most powerful single addition to a credit mix profile, both because of their long terms and large balances and because they represent the most substantial credit management commitment available to most consumers. However, opening a mortgage solely to improve credit mix is clearly not sensible; the financial decision must be primary. Auto loans and personal loans are the most common installment accounts that strengthen the mix for people who do not yet have a mortgage. For people who only have credit cards, adding a small installment loan and paying it faithfully can improve both the mix and the payment history components of the score.

Retail store credit cards count as revolving accounts but are often regarded by scoring models as lower-quality revolving accounts than major bank-issued credit cards. Having one or two retail accounts is unlikely to hurt the mix contribution, but relying heavily on store cards rather than major cards may result in a weaker mix assessment.

Should You Open New Accounts to Improve Credit Mix?

Opening new accounts specifically to diversify your credit mix should generally be approached with caution. Each new application results in a hard inquiry that temporarily reduces your score. New accounts also lower the average age of your accounts, which affects the credit age component of your score. The credit mix benefit of a new account must be weighed against these immediate costs.

For most people, credit mix improves naturally over time as life events, such as buying a car, financing education, or purchasing a home, lead to different account types being opened for legitimate financial reasons. The best approach is to understand where you stand, as this calculator helps you do, and to make credit mix a secondary consideration rather than the primary driver of borrowing decisions.
