Goals 22. Savings target (% or $) 23. Debt payoff goals 24. Big purchases (car, house, wedding)

Budgeting Methods — Choose Best Fit

Detect which method fits the user:

Method 1: 50/30/20 Rule (default for most people)

• 50% Needs: Housing, utilities, groceries, transport, insurance, minimum debt
• 30% Wants: Dining out, entertainment, hobbies, subscriptions, travel
• 20% Savings + Debt Payoff: Emergency fund, retirement, extra debt, goals

Use when: stable income, want simple framework, not in debt crisis.

Method 2: Zero-Based Budgeting

Every dollar assigned a job. Income - Expenses - Savings = $0. Track in categories with monthly reset.

Use when: variable income, getting out of debt, want maximum control.

Method 3: Envelope Method (Cash or Digital)

Pre-allocate fixed amounts per category. When envelope is empty, no more spending in that category until next period.

Use when: chronic overspending in specific categories, behavioral problem not math problem.

Method 4: Pay-Yourself-First

Save % automatically before any other spending. Spend the rest freely.

Use when: high income, high savings rate desired, hate tracking expenses.

Method 5: 60/20/20 (Aggressive Savers)

• 60% Needs + Wants
• 20% Retirement
• 20% Other savings/debt

Use when: FIRE-track, high earner, behind on retirement.

Analysis Framework

Step 1: Categorize Every Dollar

Group all expenses into:

• Survival (housing, utilities, basic food, basic transport, insurance, min debt)
• Lifestyle (dining, entertainment, shopping, hobbies, subscriptions)
• Goals (retirement, emergency fund, extra debt, sinking funds)
• Waste (forgotten subscriptions, fees, impulse buys, lifestyle creep)

Step 2: Benchmark Each Category

Step 3: Identify Waste (Top 5 Categories to Audit)

1. Subscription audit — list every recurring charge >$5/month, ask "still using?" 2. Bank/credit card fees — overdraft, ATM, annual, interest 3. Insurance shopping — auto/home insurance every 2-3 years 4. Dining frequency — count times eating out per week 5. Lifestyle inflation — categories that grew >20% YoY without income growth

Step 4: Find the $500 (Quick Win)

Find $500/month of reducible spending. Common sources:

• Unused subscriptions ($50-150)
• Dining out frequency reduction ($100-300)
• Cell phone plan switch ($30-80)
• Insurance reshopping ($50-200)
• Grocery meal planning ($100-200)
• Cutting one premium service ($20-50)
