- Examples are illustrative and simplified.
- Results depend on your inputs and assumptions and are not guaranteed.
- Emergency expenses and income changes are unpredictable.
Quick answer
Add up monthly essentials, pick a months target that fits your income stability, and compare scenarios to see how long it might take.
Use the planner to adjust coverage months, tweak contributions, and watch how the completion date shifts.
What this tool does (and does not do)
- Estimates a target based on your monthly expenses and chosen months of coverage.
- Estimates a timeline using your current savings and planned monthly contributions.
- Does not guarantee you will be covered for every event or timing.
- Does not model every expense, tax detail, insurance rule, or debt nuance.
Inputs explained
Enter realistic numbers and revisit them as bills change. For guidance on risk settings, see the risk level explainer.
| Input | What it means | Tips |
|---|---|---|
| Monthly expenses | Essential costs across housing, utilities, groceries, transport, insurance, minimum debt payments, and must-keep subscriptions. | Use your latest statements and budget; exclude discretionary spending you could pause. |
| Months of coverage | How many months of essentials you want to cover. | Try ranges (e.g., 3, 6, 9) to see how targets and timelines change. |
| Risk level / income stability | Signals how steady or variable your income feels. | Higher risk can justify a higher months target; see risk level explained. |
| Current savings | The amount already set aside for emergencies. | Exclude funds earmarked for other goals to avoid double counting. |
| Monthly savings capacity | How much you plan to add each month toward the fund. | Base it on your cashflow; test minimum, base, and stretch amounts. |
Outputs explained
The planner surfaces the key numbers you need; for step-by-step use, see the how-to guide.
Monthly expenses total: Adds up the essentials you entered to anchor the target.
Target fund: Monthly total multiplied by your chosen months of coverage.
Shortfall or surplus: Shows the gap between the target and your current savings (or how far ahead you are).
Months needed and completion date: Estimates how long reaching the target could take based on your monthly savings.
Weekly savings estimate: Converts the plan into a weekly amount to make contributions easier to plan.
Charts and exports: Visualize progress, see scenario comparisons, and export a summary for later review.
Three worked scenarios
Use these round-number examples to see how coverage months and contributions change the path.
| Scenario | Monthly expenses | Months target | Current savings | Monthly savings | Result summary |
|---|---|---|---|---|---|
| A: Stable income | $2,500 | 3 months | $1,500 | $400 | Target $7,500; shortfall $6,000; about 15 months to reach with steady $400 adds. |
| B: Moderate income | $3,000 | 6 months | $2,000 | $600 | Target $18,000; shortfall $16,000; about 27 months to reach at $600 per month. |
| C: Irregular income | $3,500 | 9 months | $3,500 | $800 | Target $31,500; shortfall $28,000; roughly 35 months to reach if contributions stay at $800. |
As the months target rises, the required fund and timeline increase. Higher contributions shorten the time, while larger shortfalls extend it.
Scenario comparison and planning
Save multiple scenarios in the planner to test base, conservative, and stretch contributions. Compare timelines, targets, and weekly amounts side by side, then rerun after bills change or if your income shifts. For a walkthrough, see the how-to guide.
Emergency fund vs other priorities
Building a buffer sits alongside paying down debt, investing, and other goals. Higher-interest debt, job stability, dependents, and insurance coverage can change which priority you focus on first. See the discussion in emergency fund vs debt payoff.
Safety notes and limitations
- Expenses fluctuate; update your inputs often.
- Emergencies are unpredictable; the planner provides estimates, not guarantees.
- Timelines change if income, spending, or contributions move.
- Keep saved scenarios refreshed and review the Privacy Policy for data handling.
