Search question, answered
How much emergency savings do I need?
Model the monthly gap created by an income shock using essential expenses, available savings, and a target reserve so you can see how long the current buffer may last.
Worked U.S. scenario
Example scenario: enter $4,200 essential monthly expenses, $12,000 available savings, and a $1,000 monthly income-shock deficit. The result helps you compare runway and the savings target rather than relying on a generic three-month rule.
Assumptions and limits
The result depends on the expenses and savings you enter. It does not predict unemployment benefits, severance, investment returns, medical costs, or the timing of a real emergency.
What to do next
If runway is short, review expenses, debt-payment capacity, and official consumer resources before taking a high-cost financial action.
Methodology and limitations
This calculator uses transparent amortization and scenario formulas shown in the companion guide. Change one assumption at a time and compare both monthly cash flow and total cost.

Frequently asked questions
What counts as an essential expense?
Expenses needed to maintain basic housing, food, utilities, transportation, insurance, and required obligations are common starting points.
How is runway calculated?
Liquid savings divided by essential monthly expenses.
Should I take a loan if I have an income shock?
Not automatically. Review neutral options such as expense triage, hardship programs, public resources, and trusted advice first.
