Credit Card Guides
Card-by-card comparisons ranked by your actual spending, credit score improvement guides, and the debt payoff math that banks hope you never see.
How We Evaluate Credit Cards
We calculate rewards on a real $3,500/month spending budget across grocery, gas, dining, and travel. We don't just list sign-up bonuses — we calculate the net value after annual fees over a 2-year horizon. A card advertising "$750 cash back" may net you $150 in year 2 after the $599 fee is deducted.
For credit score guides, we use real FICO methodology — not credit karma estimates. The AZEO method, the utilization cliff at 30%, and the AAoA impact of closing old cards are all tested against confirmed FICO scoring models. No guesswork.

Credit FAQ
How do I choose the best credit card for my spending?
The best card depends on your largest monthly expense. If you spend heavily on groceries and dining, a tiered rewards card like the Amex Gold or SavorOne is best. For general spending, a flat 2% cash back card simplifies your rewards.
Does carrying a balance on my credit card help my score?
No. This is a common myth. Carrying a balance only results in high interest charges. The best way to build credit is to pay your balance in full every month, which maintains a low credit utilization ratio.
Should I close a credit card I no longer use?
Generally, no — especially if it's one of your oldest accounts. Closing a card can reduce your average age of accounts and your total available credit, both of which can negatively impact your FICO score.
