My friend Maya has never missed a payment in her life.

Rent, on the first of the month, for eight years. Phone bill on autopay. She pays her one credit card in full and puts 20% of every paycheck into savings. She is, by any sane definition, the most reliable borrower you could hope to meet.

Her credit score thinks she barely exists.

When she applied for an apartment last spring, the landlord ran her credit and frowned. Thin file. Not enough history. The system had nothing bad to say about her. It had almost nothing to say at all.

Maya's problem isn't Maya. It's the mirror.

The Rear-View Mirror Problem

A credit score is a rear-view mirror. It tells lenders how you handled debt in the past, and honestly, it does that one job reasonably well.

But look at what it can't see.

Your credit report contains no salary. No rent (a TransUnion survey found only 13% of renters had rent reported to bureaus in 2025). No utility bills. No savings. It doesn't know whether you spend less than you earn. It is a history of borrowing, and nothing else.

Which produces some absurd outcomes. The Consumer Financial Protection Bureau found 26 million American adults are "credit invisible," with no file at any bureau. A 2022 study by Experian and Oliver Wyman put the full number of people without a usable conventional score at roughly 49 million.

That's not a rounding error. That's one in five adults.

And the mirror is getting cloudier for everyone else too. The average FICO score fell to 715 in 2025, the first drop in over a decade.

Pay cash for everything, save aggressively, borrow nothing? The system reads your caution as risk. You did everything right and scored zero points for it.

What Affirm Figured Out

Around 2012, a group of lenders started asking a better question. Instead of "how did this person handle debt five years ago," they asked "can this person actually afford this payment right now?"

Affirm, founded by PayPal co-founder Max Levchin, built its whole business on that question. When Affirm decides whether to approve a purchase, it looks at ability to pay today, not just the bureau file. Levchin put it plainly in a 2022 Fortune interview:

"We can look at real-time data and underwrite loans in real-time... in the last 48 hours you got a new job, that changes things a little bit."

The industry calls this cash-flow underwriting. Income coming in, obligations going out, cushion in between. In its S-1 filing, Affirm said this approach let it approve on average 20% more customers than comparable products.

Does it actually work? An independent research nonprofit called FinRegLab tested it in 2019 across six lenders. Their finding: cash-flow data predicted credit risk about as well as traditional credit scores, and sometimes better. Their 2025 follow-up went further. Models combining both kinds of data beat either one alone.

The catch: Affirm only sees your cash flow at the moment you buy a couch.

Your budgeting app sees it every single day.

The Pulse Score

So we built one.

The Pulse Score lives in the Credit tab of the Budget screen. It reads your last 12 months of real activity (income, bills, balances, spending) and scores you from 0 to 100 the way a cash-flow underwriter would.

One thing before anything else: this is not a credit score. It uses no bureau data, makes no inquiry, and has zero effect on your FICO. We will never show you an estimated bureau number. If we don't have enough data to say something true, we say "not enough data." That's the deal.

Here's the clever part, if we may. The score borrows FICO's own published recipe (payment history 35%, amounts owed 30%, and so on) but swaps every input for its real-life cash-flow equivalent. So while you read your score, you accidentally learn how the actual credit system works.

Five pillars:

Pillar	Weight	What it actually measures
Bill Reliability	35%	Did your rent, utilities, and subscriptions get paid on schedule?
Debt Load	30%	Card utilization and the share of income going to debt
Cash Buffer	15%	How many months could you survive on what's in the bank?
Spending Discipline	10%	Do you finish months in the black, consistently?
Data Depth	10%	How much history we can see (maxes out at nine months)

Every pillar shows its inputs, your exact numbers, and one concrete action. No black box. If a pillar doesn't have enough data, it sits out and the others carry its weight. We don't invent a number and hope.

Four People, Four Different Problems

Scores are abstract. Situations aren't. Here's how the same five pillars read four very different lives.

Maya, 26: invisible to the bureaus

The reliable renter from the top of this post. FICO shrugs at her.

Pulse sees seven recurring bills, all arriving on schedule, month after month. Bill Reliability: perfect. Zero debt. Strong savings rate. Her score lands in the 80s and the tab shows her, in writing, the reliability the bureaus never recorded.

Her one weak pillar? Cash Buffer. Saving 20% is great, but most of it goes to a retirement account, and her checking account runs close to the bone. Her action item: keep one month of expenses liquid before maxing everything else. One transfer on payday, automated. Done.

Devon, 34: great salary, quiet problem

Devon earns six figures and has never been late on anything, so he assumes he's fine. But his cards carry a $9,000 balance against $15,000 in limits. That's 60% utilization, and it's silently the biggest weight on both his FICO and his Debt Load pillar.

Here's what Devon learns from the score that generic advice never told him: utilization resets every month. It's not a scar, it's a snapshot. Pay the balance below 30% before the statement closes and the pillar responds within one cycle. He sets up a mid-month payment, watches Debt Load climb from 51 to 78 in two months, and finally understands why "keep utilization under 30%" was always the least optional rule.

Sam, 41: freelancer with lumpy income

Three great months, then a dry spell. Banks look at Sam's income and see chaos.

The Spending Discipline pillar sees something else: 10 of the last 12 months finished positive, and spending stays steady even when income swings. That consistency is exactly what cash-flow underwriters prize. Sam's weak spot is the same one that kills most freelancers, the buffer. The score puts a number on it (1.4 months of runway) and a target (three months, the standard floor). Vague anxiety becomes a progress bar.

Priya, 29: brand new to the country

Priya arrived last year with a good job and no US credit history at all. The bureaus would take years to warm up to her.

Pulse starts scoring her within weeks of her first transactions. Data Depth starts low, but here's the design choice we're proudest of: a thin file costs her 10% of the score, not all of it, and it heals automatically. Nine months of ordinary life and the pillar is maxed. Meanwhile her on-time bills and healthy buffer are already doing the talking.

The Contrarian Bit

Standard credit advice is not wrong. Pay on time, keep utilization low, don't close old cards. Fine.

It's just unfinished. It tells you how to polish the rear-view mirror while saying nothing about the road. You can have an 800 FICO and one month of runway. You can have a "thin file" and the steadiest cash flow in your zip code. The mirror doesn't know the difference.

The habits that actually make you creditworthy (spend less than you earn, keep bills on rails, hold a buffer) were never measured by the thing everyone obsesses over.

So we measure them.

Your credit score tells you where you've been. Your cash flow tells you where you're going. We think the windshield deserves the bigger view.
