Every dollar you pay in interest is a dollar that stopped compounding for you, and started compounding for someone else. Permanently.
American families are carrying $18.8 trillion in household debt in 2026. Average credit card APRs sit above 22%. But here's what nobody shows you on your statement: when you pay a dollar in interest, you don't just lose that dollar. You lose everything that dollar would have compounded into for the rest of your life. A $10,000 debt at 22% doesn't cost you $10,000. It costs you $10,000 plus 30 to 40 years of growth that never happens for you, but does happen for the bank. Multiply that across a lifetime of car loans, mortgages, business financing, and credit lines. The real cost isn't what you owe. It's the compounding you never got.
If you added up every dollar of interest you've paid in the last ten years, and then calculated what that capital would be worth today if it had compounded in your favor instead: what does that number change about how you think about your current financial structure?
