GM Financial Credit Approval Tiers and Income Requirements
Updated: May 26, 2026
How GM Financial’s Tier System Works
GM Financial uses a tiered credit approval system. Each tier corresponds to a range of credit quality and determines the interest rate, loan terms, and programs available to a borrower.
Dealerships submit applications to GM Financial, which returns a decision (approval, counter-offer, or decline) along with rate terms based on the tier the borrower falls into.
GM Financial does not publicly publish its tier sheet. The information below is based on industry reporting, dealer experience, and publicly available auto finance data as of 2026.
Credit Score Model Used
GM Financial primarily uses the Equifax Beacon 5.0 score — an older credit scoring model specific to auto lending. This score often differs from:
- FICO 8 (shown by most credit monitoring services)
- VantageScore 3.0 (used by Credit Karma)
- FICO 9 or FICO 10
Your Equifax Beacon 5.0 score may be higher or lower than the score you see in consumer apps. Request your Equifax report directly to get the closest approximation.
Credit Tier Reference Table
| Tier | Beacon Score | Classification | Typical Rate Access | Notes |
|---|---|---|---|---|
| 1 | 720+ | Well-Qualified | Lowest promotional rates | Full new + CPO programs |
| 2 | 680–719 | Prime | Near-promotional rates | Most programs available |
| 3 | 640–679 | Near-Prime | Standard rates | May restrict loan terms |
| 4 | 600–639 | Non-Prime | Higher rates | Increased down payment common |
| 5 | 540–599 | Subprime | Significantly higher rates | Limited vehicle eligibility |
| 6 | Below 540 | Deep Subprime | Highest rates | Special programs; may require co-signer |
Note: Tier boundaries shift with market conditions. A 720 that qualified Tier 1 in 2022 may behave differently in 2026 depending on GM Financial’s current risk appetite.
Minimum Monthly Income Requirements
GM Financial generally requires a minimum monthly gross income of:
| Loan Type | Minimum Monthly Income |
|---|---|
| Standard new vehicle | $1,500/month |
| CPO (Certified Pre-Owned) | $1,500/month |
| Non-prime / subprime | $1,500–$2,000/month |
| Some high-loan-amount programs | $2,000–$2,500/month |
These are floor minimums. The actual required income depends on the vehicle price and resulting monthly payment. A $700/month payment at $1,500 income would produce a PTI of 46% — well outside approved ranges regardless of meeting the floor.
Use the GM Income Calculator to calculate your exact monthly gross income and verify PTI for any target payment.
PTI by Credit Tier
Higher credit tiers generally allow slightly higher PTI before declining:
| Tier | Maximum PTI (Approximate) |
|---|---|
| Tier 1 (720+) | Up to 20–25% |
| Tier 2 (680–719) | Up to 15–20% |
| Tier 3 (640–679) | Up to 15% |
| Tier 4–6 | Under 15% preferred; stricter |
DTI by Credit Tier
| Tier | Preferred DTI | Maximum DTI (Approximate) |
|---|---|---|
| Tier 1 | Under 35% | Up to 45% |
| Tier 2–3 | Under 40% | Up to 43% |
| Tier 4–6 | Under 35% | Under 40% |

Employment History Requirements
GM Financial typically expects:
- 2+ years at current employer (or in same field) for standard approval
- 6–12 months minimum at current employer for non-prime tiers
- New job: Offer letter accepted if start date has passed and first paycheck received
- Self-employed: 2 years in same business, documented by tax returns

Loan Term Limits by Tier
| Tier | Maximum Loan Term |
|---|---|
| Tier 1–2 | 84 months (7 years) |
| Tier 3 | 72 months |
| Tier 4–5 | 60–72 months |
| Tier 6 | 48–60 months |
Longer terms reduce monthly payments but increase total interest paid. GM Financial may cap the term at a lower number depending on vehicle age, mileage, and loan-to-value ratio.
Loan-to-Value (LTV) Limits
GM Financial considers LTV (loan amount ÷ vehicle value):
- Tier 1: Up to 120–130% LTV (allows for tax/title/accessories rollup)
- Tier 3–4: May cap at 100–110% LTV
- Tier 5–6: Often requires down payment to bring LTV to 90–100%
A large down payment improves LTV, which improves approval odds for borderline applicants.
