Emergency Fund Designer — 3-6 months expenses in high-yield savings. Not invested. Before aggressive debt payoff. The foundation that prevents one bad month from cascading into… Setup: 1 min to try · Best AI: Sonnet 4.5. · Cost: Free, MIT-licensed.
Why this is epic
Research consistently: households with emergency fund have dramatically different financial trajectory from those without. One car breakdown, medical bill, or layoff doesn't cascade into debt-spiral.
Common mistake: investing emergency fund (seeking return). When emergency hits, market may be down + you're forced-selling. Or: keeping in 0.01% checking. Solution: high-yield savings (4-5% in 2026).

📊 Promptolis Original vs generic AI prompts Click to expand
| Feature | Promptolis | Generic prompts |
|---|---|---|
| Structure: | XML + chain-of-thought | Role-play one-liner |
| Example output: | Real full example | Rare |
| Variants: | 3-7 per prompt | Single |
| Output quality: | +30-50% accurate [Anthropic] | Baseline |
On the other hand, generic prompts work fine for simple lookups. Promptolis Originals shine for nuanced reasoning where precision matters.
The prompt
Example: input → output
Here's how this prompt actually performs. Real input below, real output from Claude Opus 4.
<monthly-expenses>$4500 (rent + food + utilities + transportation + insurance + basics)</monthly-expenses> <income-stability>Stable salaried job, 2 years tenure</income-stability> <dependents>None (single)</dependents> <current-emergency-savings>$3000 in checking</current-emergency-savings> <other-savings>$12K in 401k</other-savings>
Your Target: $13,500 - $18,000
Reasoning: 3-4 months expenses = $13,500-$18,000. Single, stable income, no dependents — lower end of range works. 4 months = $18K ideal buffer.
Where to Keep
- HYSA (High-Yield Savings Account): Ally, Marcus, Capital One 360, SoFi. 4-4.5% APY in 2026.
- Separate from checking account — prevents accidental spending
- NOT invested (S&P 500, etc.) — emergency fund should not depend on market
- NOT in money market fund if requires sell + wait 1-2 days; HYSA is instant access
Avoid: keeping in checking (0.01% APY = $1350 lost over 3 years on $18K vs. HYSA 4%).
Building Plan
Current: $3K. Target: $15K (midpoint). Need: $12K more.
- At $500/mo: 24 months
- At $750/mo: 16 months
- At $1000/mo: 12 months
Recommended: $500/mo minimum. Auto-transfer on payday.
Prioritize: emergency fund BEFORE aggressive investing beyond 401k match.
When to Use
Real emergency:
- Medical emergency
- Car breakdown (major repair or replacement)
- Job loss
- Major home repair
- Family crisis requiring travel / support
Not emergency:
- Vacation
- Holiday gifts
- 'Great deal' on non-necessity
- Lifestyle inflation
When to Pause Other Goals
Build emergency fund BEFORE:
- Aggressive debt payoff beyond minimums
- Investing beyond 401k match
- Saving for house down payment
- Large purchases
Emergency fund foundation prevents cascade. Without it, one emergency = credit card debt = debt spiral. Emergency fund IS wealth-building; not competing with it.
Exception: 401k match (free money) — don't skip that for emergency fund building.

Pro tips
- 3 months expenses for dual-income households + stable jobs.
- 6 months for single-income or variable-income.
- 12+ months for pre-retirement or high-variability.
- High-yield savings account (4-5% APY 2026). Not checking; not invested.
- Calculate from actual MONTHLY expenses, not income.
- Build slowly. $200/mo = 3 months expenses in 12-24 months for most.
Customization tips
- For variable-income (freelance, commission): 6-9 months minimum. Income troughs real risk.
- For 2-income households with stable jobs: 3 months OK. Both losing jobs simultaneously is less likely.
- For pre-retirement (within 5 years): 12+ months. Job market weak at 60+; hire-back slower if laid off.
- For single parents: 6+ months regardless of income stability. No backup earner.
- For healthcare-concerns or chronic illness: add medical-specific buffer (another 1-3 months).
Variants
Default 3-6 Month
Standard for most situations
Variable Income Larger Buffer
Freelance, commission, contract
