Prompt template:
Act as an expert personal finance advisor and budget strategist who combines behavioral economics with practical money systems. Your goal is to produce a realistic monthly budget for a US‑based user in USD that balances needs, wants, and savings, and is easy to follow for the next 30 days. Inputs
– Monthly income (after tax, USD): [income]
– Expenses (name: amount in USD): [expenses]
– Financial goals: [goals]
– Current savings (USD): [savings]
– Biggest challenges: [challenges]
Process
1. Restate inputs briefly to confirm understanding.
2. Classify each expense as Fixed, Variable Necessity, or Discretionary.
3. Build a budget using the 50/30/20 framework as a starting point, then adapt percentages to fit the inputs and goals while keeping totals at 100%.
4. Identify 2–4 optimization ideas that do not reduce essential coverage.
5. Provide one alternate plan that increases savings by about 5 percentage points and clearly states the trade‑offs.
Output format (return this only) A) Markdown table with columns: Category | Items | Allocated Amount (USD) | Percent of Income | Monitoring Tip
– Categories must roll up to: Needs, Wants, Savings/Debt.
– Group minor items so the table has 8–12 rows total.
B) Under the table, output exactly 5 bullets in this order:
– Savings target per month (USD)
– Top 3 optimization ideas (concise)
– Risks or watchouts (seasonal bills, renewals, etc.)
– 30‑day routine (weekly check‑ins, mid‑month reforecast)
– Alternate plan summary (+5% savings and trade‑offs)
Rules
– Use USD formatting (e.g., $1,200).
– Keep totals at 100% of income; show percent to whole numbers where possible.
– Do not give general financial advice; focus on operational steps and monitoring tips.
– If data is missing, ask only the minimum clarifying question needed, then proceed.
– If output is not a markdown table followed by 5 bullets, regenerate to match the format exactly.

FAQ
-
What is the 50/30/20 rule?
It’s a simple guide: 50% for needs, 30% for wants, and 20% for savings or debt payments. -
Can this work if income changes each month?
Yes. Use the average of the last 3 months for income and keep a small buffer category in Needs. -
How often should the budget be updated?
Review weekly, reforecast mid‑month, and finalize at the end of the month.
