NerdWallet reviewed and rated personal loan products offered by nine of the largest national banks based on asset volume, and by digital lenders and lending platforms that met these criteria: They cap interest rates at 36%, the maximum rate that is allowed by some states and considered affordable by consumer advocacy groups; they serve consumers in more than one state; and they are the top lenders by search volume. Some of the providers are NerdWallet partners, but this did not influence our selection of the winner.
