The Math of Debt —
Why It Kills Wealth Building

Debt isn't just a monthly bill. It's a negative compound return working against you. Every dollar paying interest is a dollar that isn't earning interest. Compounded over decades, the gap is enormous.

$2,400/mo

Average American household's debt payments

Mortgage, auto loans, student loans, credit cards combined. That's $28,800/year — money that could otherwise be earning 7-10% in investments. Over 30 years at 7% growth, those redirected dollars would be worth over $2.7 million.

The compound math

Example: $10K credit card balance at 22% APR, paying minimums (2%). Time to pay off: 30+ years. Total paid: $28,000+. The bank earned $18K on your $10K of stuff.

The same $10K invested at 8% for those 30 years would have grown to $100K+. The opportunity cost of debt isn't the interest — it's the GROWTH you missed on the dollars going to interest.

What gets paid off and in what order

Two main schools: Snowball (smallest balance first, for psychological momentum) and Avalanche (highest interest rate first, for mathematical optimization). Both work. Pick the one you'll actually stick with — that's the deciding factor.

Common questions

Why is debt called a negative compound return?

Because interest you pay works against you the same way interest you earn works for you. Every dollar going to interest is a dollar not growing.

How long does it take to pay off a credit card with minimum payments?

A ten thousand dollar balance at a typical rate takes decades on minimum payments, and the interest can be more than the original balance.

Should I pay off debt or invest?

High interest debt first, almost always. A card at twenty percent is a guaranteed twenty percent return when you pay it off.
