This depends very much on the type of redemption you choose. Air miles usually deliver the best return, followed by shopping, entertainment or travel vouchers and conversion to cashback on your card, with merchandise redemptions usually trailing a long way behind in dollar value. To find out how much a point is worth for a specific redemption, work out the cost of the item if you had to buy it, and then divide by the number of points. For example, if a $50 retail voucher costs you 10,000 points, then each point is worth 0.5 cents. Also consider how much you need to spend to earn those points. Card A may give you one point per dollar spent and charge 10,000 points for a $50 voucher. So you need to spend $10,000 to get $50 back. Card B may give you two points per dollar spent, but charge 22,000 points for a $50 voucher, requiring you to spend $11,000 for the same $50 return. Card B appears better on the surface, but it only takes a quick calculation to work out that Card A gives greater value.
