Your Credit Score, Decoded

📊 Your credit score is a three-digit number that quietly decides whether you get an apartment, a car, or a humiliating phone call from a landlord. You didn't ask for a number that follows you around judging you — but here we are.

💡 Key idea

Your score (≈300–850) is built mostly from on-time payments + low credit utilization. Those two levers move it most.

🧠 Why it matters

A CREDIT SCORE (commonly 300–850) summarizes your creditworthiness in one number. It's built mostly from five things: PAYMENT HISTORY (do you pay on time — the biggest factor), AMOUNTS OWED / utilization (how much of your available credit you're using), LENGTH of credit history, NEW credit (recent applications), and CREDIT MIX (variety of accounts). Higher scores unlock lower interest rates, saving you thousands over a lifetime. The two biggest levers: pay on time every time, and keep balances low relative to your limits.

🌍 In the real world

💡 The fastest way to wreck a good score is one missed payment; the slowest, most reliable way to build one is years of boring, on-time payments. It's like a gym streak — unglamorous, but the compounding is everything.

📖 Terms in this lesson

Credit score: A three-digit number (300 to 850) that tells lenders how reliably you've paid debts back.

Credit report: Your borrowing history: accounts, balances, payments and missed payments, kept by the credit bureaus.

'Credit utilization' refers to...
