Buy now, pay later (BNPL) has become an increasingly popular online payment method in recent years. This is evidenced by the growing number of buy now, pay later users in the United States, which is forecast to rise by 11.7% in 2023, to 88.2 million. 

Klarna currently ranks among the biggest BNPL companies in the world, with an estimated valuation of $7 billion. With the US as the company’s largest market, it’s important to have an idea of how many Klarna customers there are, to evaluate whether it’s worth implementing BNPL as a payment option.
