How this calculator works

This tool starts from the classic 3-6 month rule, then adjusts it up if you're the sole income earner in your household, have dependents, or have variable/freelance income. It uses a low, conservative yield since an emergency fund should stay liquid, not invested for growth — more on that in where to keep your emergency fund.
