Credit card rental car insurance can save you a truckload of money. You won’t have to buy supplemental insurance from the rental company, and even more importantly, it covers you in the event of damage to or theft of a rental car. Coverage up to the cash value of a rental vehicle is typical, and the best credit card rental car insurance policies give up to $75,000.

Credit card rental car insurance policies are driven by three of the four major card networks: Visa, Mastercard and American Express. The other major card network, Discover, stopped offering its rental car insurance benefit in 2018. But individual credit card companies determine the specifics of the coverage that customers receive.

You can build credit with a credit card by using it every month, paying off your purchases on time and keeping a low credit utilization (less than 30%). But there are many ways to build credit with a credit card other than making purchases and payments. For instance, you could lock your credit card in a drawer, and your score would still improve.

The key, regardless of your exact approach, is to get a credit card as soon as possible and then avoid missing due dates. Simply having an open credit card account is the easiest way to build credit. And payment history is the biggest ingredient in your credit score. With that being said, we’ll lay out our ideal approach to building credit with a credit card below.
