FloatCard: Earn Card Interest

Your credit card already gives you an interest-free period. FloatCard helps you stretch it to the maximum — and by giving you the opportunity to keep your money in a money market fund during that time, it helps you earn interest every month.

How it works? Spend right after your statement closes, keep your money invested until the due date. That's typically 30–40 days. FloatCard tells you which card to use and when — you handle the rest.

💰 THE MATH
By keeping your monthly spending in a money market fund for 30–40 days, you can generate extra income every single month. The app calculates and shows your potential earnings.
