Credit, cards, and loans — how to borrow without getting burned

Frequently asked questions

What's the most important factor in my credit score?

Payment history — 35% of your FICO score. One 30-day late payment can drop a 780 score by 80–110 points. Set every minimum payment on autopay even if you pay the full balance manually.

What credit utilization is ideal?

Under 10% across all your cards combined gets you the best score. Under 30% avoids active penalty. Pay your statement balance before the statement date if you carry a high balance and want a quick score bump.

Is a 720 credit score good?

Yes — 720 qualifies for most prime rates on cards, auto loans, and mortgages. The next jump (to 760+) typically saves another 0.125–0.25% on a mortgage rate, which is meaningful over 30 years.

Should I pay off my credit card or build savings first?

Keep a $1,000 starter emergency fund, then attack credit-card debt above ~12% APR before any further savings. Math says credit-card APR > expected market return on savings, every time.

When does refinancing a mortgage make sense?

When you can drop your rate by at least 0.75% AND you'll keep the loan long enough to recoup the closing costs (usually 3,000–6,000). Cash-out refis are a separate analysis tied to what you'll do with the cash.

Personal loan or balance-transfer credit card for paying off debt?

If your credit score qualifies for a 0% APR balance-transfer offer and you can pay the debt off during the promo window (usually 12–21 months), the card wins. Otherwise a personal loan at 9–14% beats a credit card at 22%+.
