Debt and Interest, Explained
Practice lesson. Nothing here is saved to My Plan.
Interest is rent you pay for using someone else's money. Understand how it grows and you will never be surprised by a loan again; misunderstand it and it quietly eats your paychecks for a decade. Time to run the machine yourself.
Before you start: where are you now?
Rate yourself honestly. Nobody sees this but you.
The loan laboratory
Same $10,000 loan. Pick an interest rate and a monthly payment, and watch what the loan really costs:
Rates in the lab are examples: federal student loans sit at the low end, private loans in the middle, credit cards at the top. Real rates change; the shape never does.
The credit-card corollary
A $1,000 phone on a 22% credit card, paying the $25 minimum: about five and a half years, and roughly $700 in interest. The phone will be obsolete years before it is paid for. That is the minimum-payment trap in one sentence: minimums are designed to keep the loan alive, not to kill it.

The big idea
Debt is a tool with a price tag, and the price tag is interest times time. Borrow reluctantly, federal before private, pay more than the minimum, and always ask a loan the only question that matters: what is the TOTAL I will pay before this is gone?
