Interpreting Results
Start with Recommended Months. Then compare Recommended Target Fund and Conservative Target Fund before deciding what changes the answer most.
Input Steps
Field by field
- 1
Monthly Essential Expenses
Enter essential monthly expenses, current emergency savings, monthly savings capacity, dependents, job stability, and deductible exposure using bare-minimum monthly costs. Essential spending should exclude travel, dining out, and other discretionary categories.
- 2
Current Emergency Fund
Read recommended months, recommended target fund, and conservative target fund together. Stable dual-income households often land near 3-6 months, while single-income or variable-income households with dependents often need 6-12 months.
- 3
Monthly Savings Capacity
If your current fund cannot cover one major deductible plus one month of essentials, you are still vulnerable even if the dollar amount feels large. The right target depends on income risk, not online averages.
- 4
Dependents Count
Set a first milestone at one month of essentials, then a second at the recommended target, and keep the money in a liquid HYSA or similar cash account. Use the savings goal calculator to turn the target into a monthly plan.
- 5
Job Stability Score
Re-run after a job change, new dependent, housing move, or deductible change. Track months of essentials covered and the time remaining to hit the target.
- 6
Deductible Exposure
Enter deductible exposure with realistic baseline assumptions before moving to sensitivity checks.
Run one base case and one sensitivity case before trusting a single output.
