FAQ
What does "months of expenses covered" mean?
It divides your remaining savings by your typical monthly expenses, showing how long that cushion would last if no more income came in — a common way to gauge emergency fund health.
Does this simulate multiple expenses at once?
This version models a single unexpected expense against your current savings; run it again for additional scenarios.
Is this financial advice?
No — this is a simple simulation to help you think through a scenario, not personalized financial advice.
