Balance tiers: when 4.9% may not apply to every dollar.

Tiered rates can make a headline technically accurate while changing the result for a specific balance. Read whether the APY applies to the full balance, a portion, or only a qualifying tier.

Caps

A cap can limit how much of the balance earns the highlighted rate. Above that line, another rate may apply.

Minimums

A minimum can decide whether the rate is available at all. It may also interact with monthly fees.

Blended result

When different portions earn different rates, the practical result may be a blended yield rather than the headline number.
