Credit Compound

By the numbers

Facts & Data

Credit is a game of compounding, and it compounds in both directions. These are the numbers that define the industry: who owes what, what it costs, and where the points actually come from. Know the math and the cards work for you. Ignore it and you work for the cards.

The Debt Picture

How much America actually owes on plastic.

$1.2T+

Total U.S. credit card debt

Americans collectively carry more than $1.2 trillion in credit card balances, the highest figure ever recorded and roughly double the total from a decade ago.

Americans carrying card debt

About a third of American adults carry credit card debt month to month rather than paying in full. Among Gen X households it climbs closer to half.

Bankrate / Federal Reserve SHED survey

~$6,000

Average household card debt

Spread across all households, average credit card debt runs around $6,000. The average masks a split: most households pay in full, while a minority carry large revolving balances.

Federal Reserve Survey of Consumer Finances

~$16,000

Average debt among those who revolve

Count only the households that actually carry a balance and the average jumps to roughly $16,000. Debt concentrates hard in the households least able to absorb the interest.

~$10,000

Average card debt at zero or negative net worth

Households with zero or negative net worth carry about $10,000 in credit card debt on average. The people with the least cushion pay the most to borrow.

The same math that builds wealth in an index fund dismantles it on a card statement.

≈22%

Average APR on interest-bearing accounts

The average rate charged on credit card accounts that actually carry interest sits near 22%, close to the highest the Federal Reserve has ever recorded. A decade ago the same figure was under 14%.

Federal Reserve G.19 Consumer Credit release

$3,300/yr

Interest on a $15,000 balance

Carry $15,000 at a 22% APR and you pay roughly $3,300 a year in interest alone, about $9 every single day, before a dollar of principal moves. At an older 15% APR the same balance still costs $2,250 a year.

18+ years

Payoff time on minimum payments

Pay only the minimum on a $6,000 balance at today's average APR and you will be paying for roughly two decades, handing the issuer more in interest than you originally borrowed.

$130B+

Interest and fees paid annually

U.S. cardholders pay well over $130 billion a year in credit card interest and fees. That figure is the engine that funds every signup bonus and lounge on this site.

The Rates That Rule Everything

Your APR is not a random number. It is built from these.

Prime

U.S. Prime Rate

The rate banks charge their most creditworthy customers, and the benchmark nearly every variable card APR is built on. It moves in lockstep with the Fed: prime sits 3 percentage points above the federal funds target.

Wall Street Journal Prime Rate

Prime + margin

How your APR is actually set

A card priced at "Prime + 14.74%" reprices automatically every time the Fed moves. When you hear the Fed cut or hiked rates, your card APR changed within a billing cycle or two.

0.45%

What big banks pay on savings

The national average savings rate hovers under half a percent while high-yield online accounts pay several percent more. Same dollar, same FDIC insurance, wildly different outcome.

Credit Scores

The three digits that price everything you borrow.

715

Average FICO score in America

The national average FICO score is around 715, a record high. Scores range 300 to 850, and the difference between 650 and 750 can be worth tens of thousands of dollars over a mortgage.

FICO national score data

~1.5%

Of scorers hold a perfect 850

Only about one or two in a hundred FICO-scored consumers hit a perfect 850. The good news: lenders treat anything above roughly 780 identically, so perfection buys nothing.

FICO score distribution data

35%

Of your FICO is payment history

Payment history is the single largest factor, followed by utilization at 30%. Pay on time and keep reported balances low and you have mastered two-thirds of the model.

550M+

Credit cards in circulation in the U.S.

There are more than half a billion open credit card accounts in America, well over four for every adult who carries one.

Federal Reserve / network reports

~4

Cards held by the average American

The average cardholder keeps about four cards. Readers of sites like this one tend to hold double digits, and the data says that done responsibly, more cards often mean higher scores via lower utilization.

Experian consumer credit review

82%

Of U.S. adults have a credit card

Credit cards are near-universal among American adults, and cards now carry more total U.S. consumer spending than cash and checks combined.

1950

The year the modern card was born

Diners Club launched the first multi-merchant charge card in 1950 after its founder forgot his wallet at dinner. BankAmericard, the ancestor of Visa, followed in 1958 by mass-mailing 60,000 unsolicited live cards to Fresno, California.

The Rewards Economy

Where the points come from, and where they go to die.

~2%

Interchange fee on every swipe

Merchants pay roughly 2% of every credit card transaction to the banks and networks. That pool is what funds your 2% cash back. Rewards are not generosity, they are a rebate on a fee you never see.

Nilson Report / Federal Reserve interchange studies

$20B+

Rewards earned but never redeemed

By industry estimates, tens of billions of dollars in points and miles sit unredeemed, expiring or devaluing every year. Issuers count on breakage. Redeeming is the rebellion.

150,000

Largest public card bonus ever

Welcome bonuses have grown from a few thousand points in the 2000s to six figures today. The Chase Sapphire Reserve's 150k offer is the largest public bonus in the card's history, worth $3,000+ in our valuation.

Initiation fee for the Amex Centurion

The invite-only Black Card charges a $10,000 one-time initiation plus $5,000 a year, and people line up for it. Status, it turns out, compounds too.
