You can redeem 75,000 miles with Capital One for $750 in travel. Miles have a value of $0.01 per mile when redeemed for cash travel purchases, either by booking through Capital One Travel or redeeming them toward previous travel purchases. Based on that valuation, we calculate that 75,000 miles are worth $750. Keep in mind that miles are also transferable to Capital One's travel partners, which include airline and hotel loyalty programs. If you transfer your miles, the value you get depends on the award travel you book. Some cardholders get $0.02 to $0.03 per mile or more this way.
