At 4.15%, about what T-bills or a money market fund pay (as of Oct 12, 2026), the $100,000 tier adds −$150: the $1,000 bonus plus $3,000 interest, minus the $4,150 that cash would have earned in 365 days. At that rate it doesn't beat leaving the cash where it is. At a different rate the answer changes; the calculator on this page works it out for yours.
