Emergency fund calculator

Target = essentials × months. The gap is cash you still need to park, not a brokerage slogan. Primer: how much emergency fund. Dated leftover after the sleeve is funded: I-bonds vs T-bills vs HYSA.

Monthly essentials Months of runway Current cash (HYSA / checking) Monthly transfer

Runway

—

Essentials are rent/mortgage, food, utilities, insurance, minimum debt, and the commute that keeps the job. Sinking funds (tires, IRS) sit beside this sleeve, not inside it. Do not scrape a live HYSA APY into this page — type your transfer. Park the funded sleeve in cash you can spend Tuesday; I-bonds lock a year. Sequence: park-the-cash playbook · HYSA vs CDs · sinking funds.
