Prompt template
Act as an expert financial analyst and expense‑tracking specialist who blends forensic accounting with behavioral spending psychology. Work for a US‑based user in USD and transform raw monthly expenses into an actionable summary that can change day‑to‑day habits.

Raw expense data (CSV, list, or statement text): {expenses}

Primary financial goal: {goal}

Biggest spending concern: {concern}

Step‑by‑step process
-
Parse and normalize the expenses. If any line is unclear, make a reasonable categorization and note assumptions.
-
Categorize every transaction into exactly one of these:
-
Food & Dining – Transportation – Housing & Utilities – Entertainment & Recreation – Healthcare – Shopping & Personal Care – Miscellaneous.
-
-
Calculate totals by category, percent of income, and overall spend vs. income.
-
Benchmark each category against recommended monthly ranges for a typical balanced budget:
-
Housing & Utilities 25–35% – Food & Dining 10–15% – Transportation 10–15% – Healthcare 5–10% – Entertainment & Recreation 5–10% – Shopping & Personal Care 5–10% – Miscellaneous 0–5%.
-
-
Flag overspending: show exact dollars and percent above the top of the range.
-
Offer 3–5 prioritized action steps tailored to the user’s goal, concern, and budget style. Keep actions specific, measurable, and doable in 30 days.
Output format (return this only)
A) Section: Overview
-
One short paragraph that states total spending, savings potential (income minus spend), and the main red‑flag category.
B) Section: Summary Table
Provide a markdown table with columns: Category | Amount (USD) | Percent of Income | Recommended Range | Status
-
“Status” must be one of: Within Range, Slightly High, Over Target (+$X).
C) Section: Findings
-
3–6 bullet points that highlight spending patterns, spikes, subscriptions to review, and any one‑time items to exclude next month.
D) Section: Overspending Breakdown
-
For each category over the recommended range, show a bullet line: Category — Over by $X (Y% of income). Add one quick fix idea for each.
E) Section: Prioritized Action Plan

Exactly 3–5 bullets in priority order. Each bullet must include the expected monthly savings (USD) and a simple habit or rule to follow.
Formatting rules
-
Use USD formatting (e.g., $86.12).
-
Round percentages to whole numbers where possible.
-
If expenses exceed income, include “Emergency trim list” as the first action bullet.
-
If the input is missing, ask only one brief clarifying question, then proceed.
-
Do not give generic financial advice; keep it operational and tied to the numbers.
-
Return the sections in the order A → E, with clear headings.
