Credit card points are real money, but most people treat them like a freebie and lose almost all the value. Letting points expire, redeeming for low-value merchandise, ignoring transfer bonuses, paying an annual fee without using the benefit, and churning badly are the mistakes that quietly drain your miles balance. This guide maps the seven costliest slips, shows what each point is actually worth, and hands you the tracking system that protects your balance from the silent devaluation programs run in 2026.

Mistake 1 — Letting points expire (a 100% loss)
TL;DRThe costliest mistake is the most mundane. Many airline and co-branded programs apply expiration windows; transferable points last only while the account is active. Expired points are a total, irreversible loss with no refund. Tracking expiration in one place removes this risk entirely.
There is no more expensive mistake than letting a balance go to zero. And it is the most common. Someone accumulates tens of thousands of points over two years, forgets to check, and one ordinary day the program zeroes out the oldest batch. There is no guaranteed individual warning, no refund, no appeal. It is a 100% loss.
Each program has its own rule. Amex Membership Rewards and Chase Ultimate Rewards keep points alive while the account stays open and in good standing — that is the exception, not the rule. Most airline and co-branded loyalty programs apply an expiration window, often resetting on qualifying activity. The clock can run per batch or by account inactivity, so read the fine print for each program you hold.
The defense is trivial and almost no one does it: log the date of every large accrual and its expiration window. When 60 days remain, either redeem or transfer with a bonus to "reset" the clock at the destination program. Letting points expire is literally throwing money in the trash.
Mistake 2 — Redeeming for merchandise instead of travel
TL;DRThe program's merchandise catalog is the most expensive value trap. Points redeemed for an appliance or gift card are worth half or a third of their travel value. The same balance that buys a toaster buys a flight.
Programs show off appealing catalogs: headphones, an air fryer, a pharmacy gift card, all "redeemable with your points." It is the most expensive way to burn a balance that exists. In the merchandise catalog, a point is typically worth a fraction of what it is worth in a well-redeemed flight — often three to five times less.
Run the numbers. A mid-range gadget "costs" tens of thousands of points in the catalog. Those same points, transferred with a bonus to an airline program and redeemed on a flight on the right date, pay for a ticket that would cost far more in cash. You are literally throwing away half to two-thirds of the value by choosing the merchandise.
The rule is simple: points are built for travel. Redeeming for merchandise only makes sense in two cases: a balance about to expire with no viable travel destination, or a value so small it cannot fund anything airborne. Otherwise, the merchandise catalog is where value goes to die.
