Rewards are forfeited far more often than they are earned poorly. Four mechanisms account for nearly all of it, and each has a simple defense.

1. Account closure

This is the big one. Nearly every issuer rewards program provides that unredeemed rewards are forfeited when the account closes.

It applies whether you close the account or the issuer does — and issuers do close accounts, for inactivity, for risk-model reasons, or after a change in your credit profile. In many cases forfeiture is immediate.

Some issuers allow a short grace period after closure. Do not rely on one.

2. Program inactivity

Issuer cash back and points generally do not expire while the account is open and active. Airline and hotel loyalty balances are different: many expire after a defined period without qualifying activity, often 12 to 24 months.

Qualifying activity is usually broad — any earning or redeeming counts. A single purchase through the program's shopping portal, a dining program transaction, or a small points transfer typically resets the clock.

If you hold a meaningful balance in a program you rarely use, set an annual calendar reminder to generate one qualifying transaction.

3. Delinquency

Most rewards agreements permit forfeiture if the account becomes seriously past due. Terms vary — some specify 60 days, some are less precise — and reinstatement after the account is brought current is discretionary.

The practical defense is autopay for at least the minimum, which makes a serious delinquency close to impossible.

4. Redemption minimums and stranded balances

Programs with a redemption threshold — commonly $25 — leave small balances unusable. A $12 balance on a card you have stopped using is money you own and cannot access.

Before shifting spending away from a card, check whether the balance is above the redemption minimum and clear it if not.

The slower loss: devaluation

Nothing is forfeited, but the value falls. Loyalty programs reprice awards, adjust transfer ratios and change availability rules, essentially always in their own favor and often with little notice.

A points balance is a currency issued by a company that can reprice it whenever it likes. Earning toward a redemption you intend to make within twelve to eighteen months is materially safer than accumulating on the assumption that today's pricing survives.

A short checklist

  1. Redeem all rewards before closing any account, and confirm a zero balance.
  2. Note the inactivity expiration policy for every airline and hotel program where you hold a balance.
  3. Keep autopay for at least the minimum on every card.
  4. Check for stranded balances below redemption minimums once a year.
  5. Redeem toward a plan rather than accumulating indefinitely.
  6. Do not transfer points to a partner until you have confirmed the award is bookable — transfers are irreversible.
