A good credit score on TransUnion falls in the range of 661 to 780 under the VantageScore 3.0 model, which is the score you’ll typically see when you check your credit through TransUnion’s own tools. Under the FICO model, which most lenders use when pulling your TransUnion report, a good score starts at 670 and an excellent score begins at 740. The exact range depends on which scoring model is being applied to your TransUnion data, and understanding both will help you know where you actually stand.
TransUnion Score Ranges by Model
TransUnion doesn’t generate just one score. Your credit report data sits at the bureau, and different scoring models analyze that data to produce a number. The two main models are VantageScore 3.0 and FICO, and they slice the score ranges differently.
VantageScore 3.0 ranges:
- Excellent: 781 to 850
- Good: 661 to 780
- Fair: 601 to 660
- Poor: 300 to 600
FICO Score ranges:
- Exceptional: 800 to 850
- Very Good: 740 to 799
- Good: 670 to 739
- Fair: 580 to 669
- Poor: 300 to 579
When you log in to TransUnion’s free credit monitoring or check your score through a banking app, you’re usually seeing a VantageScore. When a lender pulls your TransUnion report to decide on a loan, they’re more likely using a FICO score. This means the number you see and the number your lender sees can differ by 20 points or more, even though both are based on the same underlying TransUnion data.
Why the Model Matters
The gap between VantageScore and FICO isn’t just about different labels. The two models weigh your credit behavior differently in ways that can shift your score.
VantageScore 3.0 ignores paid collection accounts entirely. If you had an old medical bill go to collections and you’ve since paid it off, VantageScore won’t count it against you. FICO 8, the version most widely used by lenders, still factors paid collections into your score. Newer FICO versions (9 and 10) have dropped paid collections too, but FICO 8 remains the standard for many lending decisions.
The models also handle rate shopping differently. When you apply for multiple auto loans or mortgages in a short window, both models group those inquiries together so they count as a single hit to your score. But VantageScore uses a 14-day window, while FICO gives you 45 days. If you’re comparing lenders over a few weeks, the FICO model is more forgiving.
Credit history length also plays a role. FICO typically requires at least six months of credit history before it can generate a score. VantageScore can score consumers with thinner files, which means you might have a VantageScore on your TransUnion report even if you’re too new to credit for a FICO score to exist.
What a Good Score Gets You
A score in the “good” range opens the door to most mainstream credit products: standard credit cards, personal loans, auto financing, and mortgage approval. You won’t get the absolute best rates, but you’ll qualify comfortably and avoid the steep pricing reserved for subprime borrowers.
The difference between good and excellent shows up most clearly in interest rates. For auto loans, borrowers in the 661 to 780 range (prime) pay an average of 6.27% on a new car loan and 9.98% on a used car loan. Borrowers scoring 781 to 850 (super prime) pay 4.66% on new and 7.70% on used. On a $30,000 new car loan over five years, that roughly 1.6 percentage point gap translates to about $1,200 more in total interest for the “good” borrower compared to the “excellent” one.
Mortgage rates follow a similar pattern. The difference between a good and exceptional score can mean a quarter to half a percentage point on your rate, which on a 30-year mortgage adds up to tens of thousands of dollars over the life of the loan. If you’re in the upper 700s and considering a major purchase, pushing into the 780-plus range before applying could save you real money.
How Your TransUnion Score Is Calculated
Both VantageScore and FICO use the same general categories of information from your TransUnion report, though they weight them slightly differently. The factors that matter most are consistent across both models.
Payment history carries the heaviest weight. Paying every bill on time, every month, is the single most important thing you can do for your score. Even one payment reported 30 days late can drop your score significantly and stay on your report for seven years.
Credit utilization, the percentage of your available credit you’re currently using, is the second biggest factor. Keeping your balances below 30% of your limits is the common guideline, but borrowers with the highest scores typically stay under 10%. This applies to each individual card and to your total utilization across all accounts.
Length of credit history rewards patience. The longer your accounts have been open and in good standing, the better. Closing old cards shortens your average account age and can lower your score. Age of accounts, mix of credit types (credit cards, installment loans, a mortgage), and recent credit applications round out the formula.
Medical Debt on Your TransUnion Report
Medical collections have been a pain point for consumers on all three bureaus. The three major bureaus voluntarily stopped reporting medical collections under $500 in 2023, and they no longer include medical debts that were paid after going to collections. A federal rule that would have removed all medical debt from credit reports was proposed but was vacated by a federal court in July 2025 on the grounds that it exceeded the agency’s authority. For now, unpaid medical collections above $500 can still appear on your TransUnion report and drag down your score, particularly under FICO 8.
Checking Your TransUnion Score
You can check your TransUnion credit score for free through TransUnion’s own website, many banking apps, and credit monitoring services like Credit Karma. These free tools typically show your VantageScore 3.0. To see the FICO score based on your TransUnion data, you can purchase it through myFICO.com or check if your credit card issuer provides FICO scores through their app.
Your actual TransUnion credit report, the detailed list of accounts, balances, and payment history that feeds into any score, is available for free once a year at AnnualCreditReport.com. Reviewing the report matters more than checking the number alone, because errors on the report are what you can dispute and fix. An incorrect late payment or an account that isn’t yours can suppress your score, and correcting it with TransUnion directly is one of the fastest ways to see improvement.
Moving From Good to Excellent
If your TransUnion score is in the good range and you want to push higher, focus on the two factors with the biggest impact. First, make sure every payment posts on time. Set up autopay for at least the minimum on every account so nothing slips through. Second, reduce your credit utilization. Paying down balances is the most direct route, but you can also request credit limit increases on existing cards, which lowers your utilization ratio without requiring you to pay anything down.
Avoid opening several new accounts in a short period. Each application creates a hard inquiry on your TransUnion report, and new accounts lower your average account age. If you’re planning a major loan application in the next six months, hold off on new credit cards or other applications until after you’ve locked in your rate. The jump from a 720 to a 760, or from a 740 to a 780, often comes down to keeping utilization low and letting your accounts age without any negative marks.
