Emergency Fund Calculator
An emergency fund calculator determines how much you should save for unexpected expenses like job loss, medical emergencies, or major repairs. This fund provides financial security and prevents going into debt during crises.

| Starter Fund | 1 month | $4,000 |
| Single, Stable Job | 3 months | $12,000 |
| Family, Stable Job | 4-6 months | $16,000-$24,000 |
| Variable Income | 6-9 months | $24,000-$36,000 |

Emergency Fund Calculator Implementation
``javascript
function calculateEmergencyFund(monthlyExpenses, situation) {
const multipliers = {
starter: 1,
singleStable: 3,
familyStable: 6,
variableIncome: 9,
selfEmployed: 12
};
const months = multipliers[situation] || 6;
const target = monthlyExpenses * months;
return {
monthsNeeded: months,
targetAmount: target,
weekly: (target / 52).toFixed(2),
monthly: (target / 12).toFixed(2),
saveIn1Year: (target / 12).toFixed(2),
saveIn2Years: (target / 24).toFixed(2)
};
}
console.log(calculateEmergencyFund(4000, 'familyStable'));
// { monthsNeeded: 6, targetAmount: 24000, saveIn1Year: '2000' }

Where to Keep Emergency Fund
High-yield savings accounts (4-5% APY) are ideal: accessible, FDIC insured, and earning interest. Don't invest emergency funds in stocks—you need guaranteed availability without risk of loss.
