Worked examples
Six months of essential expenses
expenses: 3000; months: 6; savings: 5000
- Target = 3,000 × 6 = 18,000.
- Subtract 5,000 saved to find a 13,000 gap.
Emergency fund target: 18,000
Try these inputsBuild a reserve over 26 months
expenses: 3000; months: 6; savings: 5000; deposit: 500
- Gap = 18,000 − 5,000 = 13,000.
- Divide by 500 per month: 26 whole month-end deposits.
Months to reach target: 26
Try these inputsCommon questions
How much should I have in an emergency fund?
Multiply essential monthly spending by your chosen reserve months. Three, six and twelve months are scenarios you can compare, not a universal rule. Job stability, dependents, insurance and access to other support can change your needs.
How many months does my emergency fund cover?
Divide accessible emergency savings by essential monthly expenses. Savings of 5,000 with monthly expenses of 3,000 cover about 1.67 months, assuming spending remains unchanged.
What if I am self-employed or my income varies?
Enter essential expenses and choose a reserve duration appropriate to the uncertainty you want to model. The calculator does not prescribe a self-employed reserve or assume future earnings.
Scope and assumptions
The reserve duration is a user-selected planning assumption, not a personalized financial recommendation. Count accessible savings reserved for emergencies. Expenses stay constant and savings-plan mode assumes no interest, tax or inflation; deposits occur at month end.

Calculation methods and formulas
Reserve Goal
Choose your reserve months to estimate an emergency fund target and savings gap.
Target = essential monthly expenses × reserve months; gap = max(0, target − savings).
Savings Plan
Find the number of whole monthly deposits needed to reach your selected emergency reserve.
Months = ceil(max(0, target − current savings) / monthly deposit).
