Formula
Target emergency fund = essential monthly expenses x target months. Gap = target fund - current savings. Months to target = gap / monthly contribution.
Emergency Fund Calculator
Estimate how much emergency savings you are aiming for, the gap from today and how long the gap could take to close.
How to use the result
Use essential expenses, not total lifestyle spending. Rent or mortgage, utilities, food, transport, insurance and minimum debt payments usually matter more than optional spending when you are checking a basic cash cushion.
Useful caution
This is a planning estimate. It cannot decide the right emergency fund for your job security, dependants, health needs, insurance position or local costs.
Using the Emergency Fund Calculator well
Estimate how much emergency savings you are aiming for, the gap from today and how long the gap could take to close. Enter realistic values, calculate the first answer, then change one input at a time so you can see which assumption moves the result most.
What to compare
Run a normal case, a cautious case and a stretched case. If the cautious case still works, the number is more useful. If one assumption changes the result sharply, verify that input before relying on the answer.
Before you act
This calculator is a planning aid. It cannot check whether the inputs are complete, current or suitable for a decision with financial, legal, medical, safety or tax consequences.
