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.
