Emergency Fund Basics

How big a cash buffer to target and how long contributions take to get there.

Published

An emergency fund is cash for shocks — job loss, medical bills, car repairs — so you do not rely on high-interest debt.

How much?

Common guidance is 3–6 months of essential expenses (more if income is irregular). Pick a dollar goal that matches your rent, food, insurance, and minimum debt payments.

Time to goal

The emergency fund calculator estimates how long it takes to hit a target given:

  • Current savings already set aside
  • Contribution amount and frequency (daily, weekly, bi-weekly, or monthly)
  • Expected annual return (for example a high-yield savings APY, or 0% for pure cash with no interest)

Returns compound on the same interval as your contributions in this simplified model.

Try it

Set a goal of three months of your essential costs, a realistic transfer amount and frequency, and a savings rate near a high-yield account. Adjust until the timeline feels achievable.
