According to the most recent Federal Reserve statistics, Americans’ outstanding credit card debt totals $850 billion.

And according to, the most recent national average interest rate on new credit cards is 15.02%.

Those two numbers combined would translate to about $130 billion in total credit card interest expense paid annually by Americans.

That’s a gross, and surely incorrect, estimate of Americans total credit card interest payments, for lots of reasons. So let’s say $130 billion +/- 20%. That works out to be $100-$160 billion in interest Americans are handing over to credit card issuers each year.

Combine this estimate with the roughly 220 million Americans who are age 18 or older.

That would mean voting age Americans pay annually in credit card interest:

→ $450-$709 per year, per person. (Wow.)

How to Bump Your Nest Egg by ~$100,000

Now let’s say an average young American paid off—and continued to pay off, each month—his or her average credit card debt and contributed the saved interest cost to a Roth IRA for 40 years. If the Roth earned just 5% annually, the account balance at the end of 40 years would be in the range

→ $54,000-$86,000

If a 7% annual return were achieved, the account balance would reach

→ $90,000-$142,000

Moral of This Story

Because I’m lazy, I’ve played fast & loose with the numbers here and my results are gross estimates only. But I think the takeaway message is valid:

Simply by not carrying a credit card balance over your adult lifetime—not by abandoning your latte or skipping a (saved for) Disney trip or wearing only second hand clothes or otherwise adopting all the habits of discipline and denial we money bloggers are constantly harping about—you could fund a meaningful chunk of a retirement nest egg.

Pay off your high-interest debts like credit card debt as soon as you can. It’ll make a big difference.
