Emergency Fund Runway Calculator
See how many months your savings would last if you lost your income. Adjust expense cuts and part-time income to find your safety net.
3-6 months of expenses is the standard emergency fund target. Freelancers and variable-income households often aim for 6-12 months.
Your savings of $50,000 cover 1 years 2 months of expenses — that's above your 6-month target.

Why an Emergency Fund Matters
An emergency fund is cash set aside for unexpected expenses or income loss — job loss, medical emergencies, urgent home repairs. Financial planners typically recommend 3-6 months of essential expenses, though the right number depends on your situation.
Tips
- Keep your emergency fund in a high-yield savings account, not invested in the market.
- Re-calculate after major life changes: new job, move, marriage, or children.
- If self-employed or in a volatile industry, aim for 6-12 months of expenses.
Actual runway depends on access to credit, unemployment benefits, insurance, and family support. This is a simplified estimate, not financial advice.
