What belongs in monthly emergency expenses?

Use the amount required to keep your household safe and functioning—not your normal total spending. Focus on bills you would still need to cover after a job loss, medical event, urgent repair, or other disruption.

Home and basics

Rent or mortgage, utilities, basic groceries, phone service, and essential household supplies.

Health and protection

Insurance premiums, prescriptions, necessary care, child care, and costs for dependents.

Keep life moving

Transport, minimum debt payments, required subscriptions, and other unavoidable commitments.
