Bank bonus worth-it calculator
A bank bonus is worth it when the bonus plus the account's interest, minus fees, beats what the same cash would earn in a high-yield savings account. As of Nov 1, 2026, the top savings rate CashWars verified is 4.01% APY (Vio Bank (division of MidFirst Bank)), so that's the default comparison.
