FICO vs VantageScore

TL;DR

• FICO was founded in 1989 and powers ~90% of US consumer lending decisions. VantageScore was founded in 2006 by the three bureaus as a competitor, and dominates consumer-facing "free score" products.
• Both current versions (FICO 8/9/10/10T and VantageScore 3.0/4.0) use a 300–850 range. Older VantageScores (1 and 2) used 501–990 — if you see that range, it's a legacy model.
• FICO needs 6 months of credit history before it can generate a score. VantageScore only needs 1 open account and 1 month of reporting — so brand-new credit users usually see a VantageScore first.

History

FICO (originally Fair Isaac Corporation) launched the first general-purpose credit risk score in 1989. By the mid-90s, the three bureaus had all licensed FICO's model, and by 1995 Fannie Mae and Freddie Mac required FICO for mortgage underwriting. That mandate is why FICO still dominates US lending 30 years later.

VantageScore was launched in 2006 as a joint venture between TransUnion, Equifax, and Experian. The pitch: a single scoring model that gives more consistent results across bureaus, built on newer statistical techniques, that the bureaus wouldn't have to pay FICO a license fee to use. It never displaced FICO in underwriting, but it ate the consumer-facing market — Credit Karma, Capital One CreditWise, Chase Credit Journey, and most bank apps show a VantageScore, not a FICO.

Score ranges

Both current versions use 300–850. This is the source of most confusion — the number looks like it should match across models, but the weighting inside each model is different, so the same file can score 40+ points apart.

VantageScore 1.0 (2006) and 2.0 (2010) used 501–990. If any source ever shows you a number in that range, it's a legacy VantageScore, and you should ignore it for any modern decision.

Minimum data to generate a score

FICO requires:

• At least one account open for 6+ months
• At least one account reported to the bureaus in the last 6 months
• No notice of deceased on the file

If you're brand new to credit, you are "credit invisible" in FICO's eyes for your first 6 months.

VantageScore requires:

• At least one open account, ever
• At least one account reported to the bureaus in the last 24 months

VantageScore can score you within weeks of opening your first card. This is why new credit users often see a VantageScore in an app before any lender can pull a FICO for them.

Factor weightings

The five factors both models use are roughly the same, but weighted differently.

| Factor | FICO (classic) | VantageScore 3.0 | |---|---|---| | Payment history | 35% | ~40% (listed as "extremely influential") | | Credit utilization | 30% | ~20% ("highly influential") | | Length of credit history | 15% | ~21% (includes age + type mix) | | New credit | 10% | ~5% | | Credit mix | 10% | included with length |

VantageScore also explicitly weights total debt as a standalone factor ("moderately influential"). FICO folds that into utilization.

The practical effect: VantageScore is more sensitive to payment history and less punishing for new inquiries than FICO. A new card opening can drop FICO by ~5 points and VantageScore by ~2. A single late payment hits both hard.

Utilization handling

FICO classic looks at utilization at the time of the most recent statement close reported to the bureau. VantageScore 4.0 uses trended data — it looks at how your utilization has moved over the last 24 months. Someone who pays in full every cycle scores higher in VantageScore 4.0 than someone with the same current utilization who's been carrying balances.

FICO 10T also uses trended data. It's the first FICO model to do so, and it's slowly rolling out (mostly to mortgage lenders starting in 2025-2026).

Which one do lenders actually use?

For US consumer lending:

• Credit cards — 90%+ use FICO 8 or FICO Bankcard 8.
• Auto loans — usually FICO Auto 8 or FICO Auto 9.
• Mortgages — FICO 2/4/5 today, migrating to FICO 10T + VantageScore 4.0 per the FHFA mandate. See FICO model versions.
• Personal loans — mix. Older lenders use FICO 8. Fintech lenders (SoFi, Upstart, Affirm) often use VantageScore 3.0 or 4.0, or a custom model.
• Rent / tenant screening — usually VantageScore.
• Credit Karma / CreditWise / similar apps — always VantageScore 3.0.

Full breakdown: Who uses which score.

The Credit Karma confusion

The #1 question people ask: "Why does Credit Karma show 750 but my mortgage lender said 698?"

Credit Karma shows VantageScore 3.0 from TransUnion and Equifax. Your mortgage lender pulls FICO 2 (Experian), FICO 5 (Equifax), and FICO 4 (TransUnion) — the "tri-merge" — and uses the middle score.

Those are five different models across three bureaus. A 50-point gap between Credit Karma's VantageScore and a mortgage FICO is completely normal.

Bottom line

• The number on Credit Karma is real but it's usually not the one a lender will read.
• Before a mortgage or major loan, pay to pull your real mortgage FICO (myFICO.com has it).
• Before a credit card app, check your Experian FICO 8 — that's what most issuers read.
• Don't panic when the numbers don't match. Optimize for the model the next lender will actually use.
