Achieving a credit score higher than 850 can unlock benefits like premium credit card offers, lower interest rates, and higher credit limits. Maintaining such a score requires diligence in paying off balances, checking credit reports, and being patient. To join the 850 Credit Score Club, manage your debts wisely, avoid co-signing, and maintain a mix of credit types. It takes years to build a score over 800, and while income doesn't directly impact credit scores, it can affect payment timeliness.
