FAQ
Does this calculator use live APY or transfer-speed data?
No. You enter APY, delay and fee assumptions after checking official bank pages and account disclosures.
When can a higher APY still be a bad switch?
When the dollar gain is small, transfer holds are long, emergency access is weaker, fees apply or deposit-insurance/account-ownership details are unclear.
Should I keep all emergency savings at the highest APY bank?
Not necessarily. Some users keep a smaller immediate-access buffer at a familiar bank and move only excess cash after verifying official terms.
Is this financial or banking advice?
No. It is educational planning math, not personalized financial, tax, legal, credit or banking advice.
