What this emergency fund calculator shows you
An emergency fund calculator sets a savings target based on your essential monthly expenses. Choose how many months of cover you want — commonly 3 to 6 — and it returns your fund target, how much you still need, your progress, and the time to reach it at your saving rate.
How big should my emergency fund be?
A common rule is 3 to 6 months of essential expenses. Three months may be enough with stable, dual income; six or more suits single earners, variable income or anyone wanting extra security. If your essentials are $3,000 a month, a 6-month fund is $18,000.

Emergency Fund FAQ
How much should I have in an emergency fund?
A common guideline is 3 to 6 months of essential expenses. If essentials are $3,000/month, that's $9,000–$18,000.
What counts as essential expenses?
Essential expenses include housing, food, utilities, insurance, transport, and minimum debt payments.
Where should I keep my emergency fund?
Keep it in a high-yield savings account that is safe, liquid, and separate from daily spending money.
Should I build an emergency fund or pay off debt first?
Many start with a small buffer, then pay high-interest debt, then grow the fund to 3–6 months of expenses.
How long will it take to save my emergency fund?
Divide the remaining target by monthly savings. For example, $13,000 ÷ $400 ≈ 33 months.
