What is Capital One?

Capital One bills average around $550/month for a typical household. Capital One backdates external-bank payments to the date your bank processed them, the 2 to 3 day posting lag doesn't count against your due date.

Can I Pay Capital One With a Credit Card?

Yes, and it's the whole point. Most billers don't reward you for how you pay. Through Neobanc, your card earns its normal rewards and Neobanc adds 1% to 2% cash back on top. On a typical $550/month Capital One bill, that's roughly $264 back per year between a 2% cash-back card and Neobanc, for the exact same bill.

The Math on Your Capital One Bill

Average $550/month: a 2% cash-back card returns about $11.00/month, and Neobanc adds $5.50 to $11.00 on top, roughly $264 per year for switching how you pay, not what you pay.

How do I save the most on my Capital One bill each month?

Change how you pay before what you pay. Paying by bank transfer or Auto Pay earns nothing; the same bill through Neobanc with a cash-back card returns about $264 a year. Interest keeps accruing at your card's rate (~20 to 22%) and missed payments are reported to the bureaus. A recurring Neobanc payment a few business days before the due date earns on every cycle and never runs late.
