Why 5 months?
  • 3 months is the baseline for every household.
  • +2 months because your household relies on a single income.

How we calculate your target

We start with the standard 3 months of essential expenses and add time for the risks that make emergencies more likely or longer:

  • Variable income (freelance, commission, gig, seasonal): +3 months
  • Some job or industry risk: +1 month
  • Single-income household: +2 months
  • Dependents: +1 month
  • Homeowner (roofs, HVAC and water heaters fail without warning): +1 month

The target is capped at 12 months — beyond that, extra cash usually works harder invested.

How to build it faster

  1. Get to $1,000 first. A starter fund stops small surprises from going on a credit card.
  2. Automate a transfer on payday into a separate high-yield savings account.
  3. Send windfalls straight to the fund — tax refunds, bonuses and raises.
  4. Trim one or two wants temporarily. The Budget Calculator shows where your money goes.

Save a starter fund of $1,000–$2,000 first, then pay off high-interest debt like credit cards, then finish building 3–6 months of expenses. Keep contributing enough to get any 401(k) match throughout.
It depends on your expenses. $10,000 covers about 3 months if your essential costs are around $3,300 a month, but less than 2 months if they're $6,000. Divide your fund by monthly essential expenses to see how many months you're covered.
