Prompt
Act as a practical financial educator. Do not give me investment advice: just help me organize my money.
Monthly net income: {{income}}
Fixed expenses: {{fixed}}
Approximate variable expenses: {{variable}}
Debts: {{debts}}
Goal: {{goal}}
1. Classify my expenses into needs, wants and savings/debt and compare them with the 50/30/20 rule (explain whether it makes sense in my case).
2. Propose a monthly budget table with amounts per category.
3. Identify 5 concrete adjustments to free up money, ordered by impact.
4. Calculate how many months it would take to reach my goal with the proposed budget.
5. Give me a tracking template for a spreadsheet (columns and formulas).
Show the calculations so I can check them.How to use it
Use approximate figures: there is no need to share bank or personal data. For major investment or debt decisions, consult a financial professional.
Usage example
Income: $2,800 · Goal: emergency fund covering 3 months of expenses.
Sample output
1. Classification and the 50/30/20 rule
| Group | Expenses | Total | % of $3,000 | Benchmark |
|---|---|---|---|---|
| Needs | Rent 1,100 + utilities 120 + internet 70 + transport 60 + groceries 400 | $1,750 | 58.3% | 50% |
| Wants | Leisure 250 + online shopping 150 | $400 | 13.3% | 30% |
| Savings | 3,000 − 2,150 | $850 | 28.3% | 20% |
Rent alone is 36.7% of your income, so going over 50% on needs makes sense. You offset it by keeping wants low: your split is healthy.
2. Proposed budget
| Category | Current | Proposed |
|---|---|---|
| Fixed | $1,350 | $1,350 |
| Groceries | $400 | $400 |
| Leisure | $250 | $200 |
| Online shopping | $150 | $50 |
| Savings | $850 | $1,000 |
4. Time to reach the goal
- Today: 4,000 ÷ 850 = 4.7 → 5 months
- With the changes: 4,000 ÷ 1,000 = 4 months
5. Tracking template
Columns: Date | Item | Category | Amount | Type Spend per category: =SUMIF(C:C,"Leisure",D:D)…
