Start with your essential monthly expenses, not an arbitrary target. Review the last three months of housing, food, utilities, transport, insurance and minimum debt payments. Add those categories to calculate one month of essential costs.\n\n## Choose a reachable first milestone\nA full emergency fund takes time. Begin with a smaller milestone that covers a common unexpected bill, then progress toward one month and eventually several months of essential costs.\n\n## Make the contribution visible\nRecord the emergency fund as a financial goal. Choose a monthly contribution that still leaves enough cash for regular bills. Automating a transfer can help, but record it as a transfer rather than an expense so reports stay accurate.\n\n## Review after life changes\nRecalculate essential costs after a move, job change, new loan or major family change. The right target is based on your current obligations.
