Quick answer: A single-income household can size emergency savings around essential expenses, income-replacement risk, dependents, and realistic time to find replacement income.
Why one income changes the risk
When one paycheck supports most or all essential expenses, losing that income can affect the entire household at once. That makes the time needed to replace income especially relevant.
Estimate essential monthly burn
Separate survival-level household costs from discretionary spending, then use that essential number when thinking about months of coverage.
Consider backup resources carefully
Severance, unemployment benefits, a partner's potential income, and other resources may affect the plan, but availability and timing are not guaranteed.
Build the reserve progressively
Start with a reachable first milestone and increase the target as cash flow permits.
