Experian Boost, UltraFICO and cash-flow data: what lenders see

You pay your phone bill, your electric bill and your streaming subscriptions on time every single month, and none of it shows up on a standard credit report. That gap is what “alternative data” products try to close. The two names you’ll hear most are Experian Boost and UltraFICO, and they work in completely different places.

Boost changes what’s sitting in your Experian file. UltraFICO doesn’t touch your file at all: it’s a separate score a lender can order with your permission. Which one a given lender will actually see decides whether either one helps you, because a boost the lender never looks at is worth zero.

What Experian Boost adds to your file

Boost connects to the bank or card account you pay bills from, scans up to two years of payments, and adds qualifying on-time bills to your Experian report. According to Experian’s product page, a bill generally needs at least three payments in the last six months, with one in the last three months.

Eligible bill types, per Experian:

• Mobile and landline phone
• Utilities: electric, gas, water, waste, and solar
• Internet, cable and satellite TV
• Video streaming services
• Insurance paid monthly (home, auto, life and similar). Health insurance doesn’t count.
• Rent, but only online payments to select property managers or rent platforms. Cash, money orders, personal checks and peer-to-peer app payments don’t qualify, and Experian excludes rent if you already have a mortgage or another rent tradeline on your Experian file.

Experian says Boost is free and says most people see an instant FICO Score 8 increase averaging 13 points. That is Experian’s own figure with no published methodology, and Experian also says some people see no change or a decrease. If your score drops, you can disconnect the accounts and Experian says the score should go back to its prior level.

Which scores Boost can change, and which it can’t

Experian’s two pages describe this a little differently. The product page footnotes its results as “calculated based on FICO Score 8.” Experian’s education article goes further and lists FICO Score 3, 8, 9 and 10 plus VantageScore 3 and 4. Either way, two limits hold:

That third row is the one people miss. Card issuers and auto lenders each choose which bureau to pull, and plenty of them pull Equifax or TransUnion. You can check which bureau a lender used on the adverse action notice if you’re turned down, or just ask before you apply.

Why one bureau moving often changes nothing for a mortgage

Mortgage lenders pull all three bureaus and use the middle score, so a change on one bureau only matters if it changes which score lands in the middle. Boost isn’t on Experian’s list for FICO Score 2 in the first place, but run the arithmetic anyway, because it applies to any one-bureau fix.

Example: your three scores are 668 (Equifax), 655 (TransUnion) and 640 (Experian). The middle score is 655.

• Experian rises 13 points to 653. Ranked, the scores are 668, 655, 653. The middle is still 655.
• Experian rises 20 points to 660. Ranked: 668, 660, 655. The middle becomes 660, a 5-point gain on the number the lender actually uses.

A single-bureau improvement only helps your mortgage score when it pushes the low score past the middle one, and even then you gain only the distance to the old middle. The middle score calculator lets you test your own numbers, and the scores mortgage lenders actually pull covers which versions are in play right now.

How the 2026 UltraFICO Score works

You can’t add UltraFICO to your report. It lives on the lender’s side. FICO and Plaid announced a partnership on November 20, 2025 to build a new version, and FICO announced general availability on May 20, 2026.

FICO describes the process like this. When a participating lender offers it and you agree, you link your checking, savings or money market accounts through Plaid. The score combines your regular FICO Score with what your bank data shows: money coming in and going out, how stable your balances are, how consistent your deposits are, and how you spend. It’s distributed through Plaid Check, Plaid’s consumer reporting agency, and FICO says it sits on the same scale lenders already use for FICO Scores.

FICO’s own analyses, compared with traditional credit data alone, claim:

• A 7% relative increase in approvals with no incremental risk
• A 15% relative performance lift for prime applicants with limited credit histories
• 79% of non-prime applicants with a history of positive account balances getting higher scores

Read that last number carefully. It’s 79% of a group already selected for positive balances. If your account regularly dips toward zero or overdrafts, the same data that helps someone else is evidence against you. FICO’s announcement doesn’t spell out how many people score lower, so nobody outside FICO can say how often that happens.

Cash-flow data you may already be using without knowing it

Bank-account data has been part of mortgage underwriting for a few years. Since September 18, 2021, Fannie Mae’s Desktop Underwriter has been able to spot recurring rent payments in an applicant’s bank statement data, with the applicant’s permission, and count consistent payments in their favor. Fannie Mae said at launch that fewer than 5% of renters had rent reported to the bureaus, and that missed or inconsistent payments in the bank data would not count against the applicant. Eligibility rules for that feature have their own requirements, so ask your loan officer whether it applies to your file.

This is a different path from rent reporting, which puts rent on your actual credit report. The Fannie Mae feature never touches your report; it only works inside that one underwriting system.

Is it worth linking your bank account?

Linking makes sense when your bank history is clean and your credit file is short. It’s riskier when your balances run close to zero or you’ve had recent overdrafts, because cash-flow models are built to read exactly that. Boost is the lower-stakes test: you can see the before and after on your Experian FICO 8 and disconnect if it goes the wrong way.

What to do next:

1. Pull your free reports at AnnualCreditReport.com so you know what each bureau shows before adding anything.
2. If you’re applying for a card or car loan soon, ask which bureau and which score the lender uses. Boost only helps if the answer is an Experian-based score on Experian’s list.
3. If you try Boost, write down your Experian FICO 8 first. If it doesn’t rise, disconnect.
4. For a mortgage, put your effort into the factors all three bureaus see: on-time payments and low card balances. If you rent, ask the loan officer about bank-data rent verification.
5. If a lender offers to “verify your cash flow” or link your bank, look at the last three months of your balances first. If they’re steady, say yes. If they’re thin, it may be better to wait.

If your file is too thin to score at all, start with thin file vs. credit invisible, because the fix is different depending on which one you are.
