What this calculator does

An emergency fund covers essential costs if your income stops or a large unexpected bill arrives. A common guideline is three to six months of essential expenses, more if income is irregular.

Formula and method

Target = essential monthly expenses × months of coverage Months to target = ceiling((target − current savings) ÷ monthly saving)
