When to use this calculator
Use this emergency fund calculator to estimate how much cash to keep available for unexpected expenses or income interruptions. It is useful for setting a savings target based on your actual monthly spending.
Formula
Emergency fund target = monthly expenses x months to cover
- Monthly expenses are the essential costs you want covered.
- Months to cover is the number of months of expenses you want saved.
- Already saved is subtracted to show the remaining savings gap.
Worked example
For $3,500 of monthly expenses and a 6-month target, the calculator estimates a $21,000 emergency fund. If $8,000 is already saved, the remaining gap is $13,000.
Common mistakes
- Using total lifestyle spending instead of essential expenses without meaning to.
- Keeping emergency savings in risky or hard-to-access investments.
- Forgetting deductibles, urgent repairs or job-search costs.
