Generally, you'll likely need a personal credit score of 680 or higher to get approved for a business credit card.
Here's a rough idea of what different score ranges might mean:
Excellent (750+): Best chance for cards with good rewards and rates.
Good (700-749): Good chance for cards with decent terms.
Fair (650-699): Might have fewer options or higher interest rates.
Poor (below 650): Approval could be tough; consider secured cards or improving your score first.
Keep in mind, that banks also look at your income, credit history, and how much debt you have compared to your income.
