Credit & Borrowing

APR vs. APY, loans of every kind, credit vs. debit, credit scores, and what borrowing really costs over time.

APR, APY, and the Cost of Borrowing
APR and APY are the two percentages that decide what borrowing costs you and what saving earns you — and why the same $1,200 emergency can cost wildly different amounts depending on how you finance it.
Secured vs. Unsecured Loans
Every loan is built from the same four parts — and whether it's backed by collateral changes both the interest rate you pay and what you stand to lose.
Auto Loans and Mortgages
The two biggest loans most people ever take are both secured installment loans — but their terms, and the size of the total interest bill, differ enormously.
Payday Loans and Other High-Cost Borrowing
A short list of borrowing options — payday loans, title loans, rent-to-own — are engineered to look small and end up enormous. Recognizing them is a financial survival skill.
HELOCs and Borrowing Against Your Home
Once you own part of a home, that ownership stake can itself be borrowed against — at low rates, but with your house on the line.
Credit or Debit?
They look identical and swipe the same way, but a debit card spends money you already have while a credit card borrows money you'll owe — and that one difference changes everything.
Credit Cards: How They Actually Work
A credit card is nearly free if you pay in full and expensive the moment you don't — and the mechanics of the billing cycle, the grace period, and the minimum payment explain exactly why.
How to Evaluate a Credit Card
No two credit cards are the same — comparing their fees, APRs, rewards, and issuers lets you pick the card that fits how you actually spend, and explains why many people carry more than one.
What Is a Credit Score, and How Do You Build One?
A single three-digit number, built from your borrowing history, quietly shapes what you can borrow, what it costs, and even where you can live — and you start building it earlier than you might think.
How to Be Responsible with Credit
Credit is a genuinely useful tool that becomes dangerous through a few specific, avoidable mistakes — this lesson is the playbook for staying on the right side of that line, and for climbing out if you slip.
