Credit Mix: What It Is and Whether It’s Worth Trying to Improve
Of the five factors in a FICO Score, credit mix is the smallest — just 10% — and it’s also the one most likely to lead people astray. It’s common to see advice suggesting you should open a car loan or a store card just to “diversify” your credit file. According to myFICO’s own guidance, that’s usually the wrong move. This guide explains what credit mix actually measures, why it carries so little weight compared to the other factors, and when (if ever) it’s worth thinking about.

What “Credit Mix” Actually Means
Credit mix refers to the variety of account types on your credit report. According to myFICO’s explanation of credit mix, lenders and scoring models generally look at two broad categories:
- Revolving accounts — credit cards, retail store cards, and home equity lines of credit (HELOCs). These have flexible monthly payments and a credit limit you can borrow against repeatedly.
- Installment accounts — mortgages, auto loans, student loans, and personal loans. These have a fixed payment amount and a defined payoff date.
Having experience managing both types — responsibly, over time — shows lenders you can handle different repayment structures. That’s the entire idea behind this factor.
Why Credit Mix Only Carries 10% of Your Score
| FICO Score Factor | Weight |
|---|---|
| Payment History | 35% |
| Amounts Owed (Credit Utilization) | 30% |
| Length of Credit History | 15% |
| New Credit | 10% |
| Credit Mix | 10% |
Approximate weighting used in the general FICO Score model. Exact impact varies by individual credit profile and scoring version.
myFICO is direct about this factor’s limited influence, noting that credit mix “most likely won’t determine whether or not you obtain credit from lenders.” It’s a real factor, but it’s the smallest lever on the board — tied with new credit for last place.
Should You Open a New Account Just to Improve Your Mix?
This is the single most important thing to understand about credit mix: myFICO explicitly advises against it. Their own guidance states plainly that “with credit mix being such a small percentage of your credit score, the answer is, ‘probably not.'”
Here’s why chasing credit mix tends to backfire:
- Opening a new account generates a hard inquiry, which has its own (separate) small negative effect on your score.
- A new account lowers your average account age — a factor worth 15%, considerably more than the 10% you’re trying to improve.
- Taking on debt you don’t actually need (like an auto loan) just for score purposes runs real financial risk that has nothing to do with your credit score.
In short: the math rarely works in your favor. A 10% factor isn’t worth risking a 15% factor and taking on unnecessary financial obligations.
When Credit Mix Naturally Takes Care of Itself
For most people, credit mix improves naturally over the course of normal financial life — not through deliberate score-chasing:
Getting a Mortgage
If and when you buy a home, your mortgage becomes an installment account that diversifies your file automatically, alongside whatever revolving credit cards you already carry.
Financing a Car You Actually Need
An auto loan is a common installment account that many people take on for transportation needs — not for score-building — and it happens to add mix as a side effect.
Building From Credit Cards First
If you’re just starting out, it’s completely normal to have only revolving credit (one or two cards) for years. That’s not a mistake — it’s simply where most people begin, and other factors like payment history and utilization matter far more at this stage. Our guide on building credit from zero covers exactly how to prioritize in the early stages.
Common Mistakes People Make With Credit Mix
Mistake 1: Opening a Store Card Purely for “Mix” Reasons
Store cards typically carry high APRs and low limits. Opening one purely to diversify your file adds real cost and utilization risk for a factor worth only 10%.
Mistake 2: Taking Out a “Credit Builder” Loan You Don’t Need
Credit-builder loans can genuinely help people with thin credit files establish payment history and, incidentally, add an installment account. But they should be chosen because you need to establish history broadly — not purely to check a “credit mix” box.
Mistake 3: Ignoring the Bigger Factors While Focused on Mix
Because credit mix gets discussed often online, it’s easy to overweight its importance. Time spent optimizing a 10% factor is better spent making sure payment history and utilization — 65% of your score combined — are as strong as possible.
Frequently Asked Questions
Do I need both a credit card and a loan to have good credit?
No. Plenty of people have excellent credit scores with only credit cards and no installment loans. Credit mix is a minor factor, not a requirement.
Will paying off my only installment loan hurt my credit mix?
It can have a small effect once the loan is closed, since it may reduce the diversity of your active accounts, but the effect is generally minor compared to the benefit of being debt-free.
Should I get an auto loan just to improve my credit mix?
No. Taking on debt you don’t need for a 10% scoring factor isn’t a sound financial decision. Only take on installment debt for a genuine need (a car, a home, education).
Does having too many credit cards hurt my credit mix?
Credit mix measures variety of account types, not quantity within a type. Having many credit cards affects other factors (utilization, average age, new credit) more directly than mix.

Conclusion
Credit mix is real, but it’s the smallest factor in your FICO Score, and myFICO’s own guidance is clear that chasing it by opening unnecessary accounts usually does more harm than good. The better strategy is almost always the same: focus on payment history and utilization first, let your credit age grow naturally, and let your credit mix diversify on its own as your financial life evolves — a mortgage here, an auto loan there — rather than forcing it.
