Tools
Free tools for bank treasury and CFO teams
Calculators and reports built on FFIEC Call Report filings, free with no sign-up. Each one shows where every number came from, says plainly what it does not do, and declines to estimate when the data is not there.
Net interest income rate-shock calculator
Calculator · Estimate how a Fed funds move changes a bank's loan yield, deposit cost, and net interest income, using its own filed pass-through history.
Margin capture report: loan beta versus deposit beta
Report · Compare a bank's loan beta with its deposit beta and rank the spread against its asset-band peers, from FFIEC filings.
Maturity wall refinancing calculator
Calculator · See how much of a bank's time deposits mature within a year and what rolling them over, or replacing what runs off, would add to interest cost.
For developers and AI assistants
