Emergency Fund Calculator
Estimate an emergency fund target from essential monthly expenses, current savings, target months of expenses and monthly savings amount.
How this emergency fund calculator works
The calculator adds the essential monthly expenses entered, multiplies that amount by the target months, then compares the target with current emergency savings and any one-off contribution.
What counts as essential expenses
Essential expenses are the costs you would still need to cover during an emergency or income disruption. The categories are only a starting point, so include the costs that matter for your own estimate.
Target months of expenses
The target months field controls the size of the estimate. A common target is several months of essential expenses, but this calculator does not decide the right amount for you.
Current shortfall and time to target
Shortfall is the amount still needed to reach the target entered. Time to target is estimated from that shortfall and the monthly savings amount, rounded up to the next month.
