Emergency Fund Calculator
How big the buffer should be and how long it takes to build.
Method
How it works
Monthly essential expenses multiplied by the desired months of cover gives the emergency-fund target. Current savings are deducted to show the remaining gap.
Months to reach the target divides the positive gap by monthly saving. It assumes expenses and saving remain constant and applies no investment return or interest.
Common questions
Frequently asked questions
How many months should an emergency fund cover?
There is no universal target. The relevant number depends on income stability, household obligations, insurance and how quickly expenses could be reduced; the calculator uses the coverage period you choose.
What expenses should I enter?
Include recurring essentials you would still need to pay during an income interruption, such as housing, utilities, food, insurance, transport and minimum debt payments. Exclude discretionary spending unless you deliberately want it covered.
Does the emergency fund earn interest in this calculation?
No. Time to target is calculated from current savings plus fixed monthly saving only.
