How it is calculated
Target = Monthly essential expenses × Months to cover
The gap is the target minus what you already have. The estimated time divides the gap by your monthly savings and rounds up to a full month.
Assumptions and limitations
- Interest is not included, so progress is not overstated.
- Assumes you save the same amount every month and do not use the fund while building it.
- The number of months is a personal choice. A common guideline is 3 to 6 months of expenses; people with irregular income, a single household income or dependents often prefer more.
This tool is educational and provides estimates. It is not a credit offer or financial advice. Actual terms are set by each institution.
Where to keep the fund
An emergency fund should be available quickly and not lose value. That is why it is often kept in a savings account separate from everyday checking, at an FDIC-insured bank or an NCUA-insured credit union. Keeping it separate makes it less tempting to use for things that are not emergencies.
Start with a small milestone
If the full target feels far away, focus first on saving one month of essential expenses. That cushion alone often prevents reaching for a credit card or an expensive loan when something unexpected happens.
