Emergency fund calculator: months of essential expenses
Build an emergency fund target from necessary monthly spending, choose a realistic saving schedule and avoid double-counting irregular bills.
Measure essential monthly spending
Start with housing, groceries, utilities, transport, insurance and minimum debt payments. Exclude optional spending you could pause. If essentials total 2,400 a month, three months is 7,200 and six months is 14,400. These are planning examples, not universal requirements. Use the monthly budget calculator to list your own amounts.
Set a target that fits your risks
Income stability, dependants, access to other funds and healthcare costs affect the amount you may need. First choose a starter reserve that prevents a small setback from becoming expensive debt. Then build toward a target in months of essential spending. Keep upcoming known bills in a separate reserve; the irregular bills guide explains how to spread them across months.
Translate the goal into a monthly plan
If you already have 2,400 and want 7,200 in 12 months, the gap is 4,800, so set aside 400 monthly before any interest. Use the savings goal calculator to model your schedule, and recalculate when living costs change. Prefer money you can access promptly for true emergencies; a volatile asset might be worth less precisely when you need it.
