Spark Cash Plus: $2.5K total but the regular Spark wins on yield

The Capital One Spark Cash Plus offers $2,000 cash back after $30K in three months plus a $500 travel credit, for a combined $2,500 value before the $150 annual fee. That's roughly 8.5% yield on the first $30K including the 2% base earning, but the regular Spark Cash delivers 12% on just $10K spend with no first-year annual fee. The Cash Plus only makes sense for those with extremely high spending who can also convert the cash back to Capital One miles at 1 cent per mile, turning $2,600 into 260,000 transferable miles.

The play: If you're not spending $30K in three months, skip the Cash Plus and take the Spark Cash at $1,250 total for a third of the spend.
