What counts as essential?
Use rent or mortgage, basic utilities, food, insurance, minimum debt payments and necessary transport. Exclude optional spending if you want a true emergency-only target.
Example
If essential expenses are $2,500 per month and you want a 6-month buffer, the target is $15,000. With $4,000 already saved, the remaining gap is $11,000.
Common mistakes
Do not base the target on total lifestyle spending if your goal is a lean emergency reserve. Include unavoidable payments such as insurance, medication and minimum debt payments.
Limitations
The right buffer depends on income stability, dependents, health needs, insurance, local labor market and access to credit. This is planning support, not financial advice.
