Frequently Asked Questions

How many months of emergency fund should I have?

Most financial planners recommend 3-6 months of essential expenses, with 6-12 months for freelancers or single-income households.

What counts as an essential expense?

Housing, utilities, groceries, insurance, minimum debt payments, and transportation — not discretionary spending like dining out or subscriptions.

Why include an income confidence slider?

Partial income sources like unemployment benefits or freelance gigs aren't guaranteed, so weighting them by confidence gives a more realistic runway estimate.
