# Budgeting

## When to use this skill
Use when the user says things like:
- "how do I create a budget?"
- "help me track my expenses"
- "teach me zero-based budgeting"
- "how to apply the 50/30/20 rule"
- "set up a rolling budget"


## Core Philosophy
Budgeting is the foundational discipline of personal finance. It is not about
restriction but about intentional allocation of resources. A well-constructed
budget reflects personal values, supports financial goals, and provides clarity
about where money goes each month. The goal is to make every dollar purposeful
rather than letting spending happen by default.

## Key Techniques
- **Zero-Based Budgeting**: Assign every dollar of income a specific job before
  the month begins. Income minus all allocations should equal zero. This forces
  deliberate choices about every category of spending.
- **50/30/20 Rule**: Allocate 50% of after-tax income to needs, 30% to wants,
  and 20% to savings and debt repayment. This provides a simple framework for
  those starting out.
- **Envelope System**: Use physical or digital envelopes for discretionary
  categories. When an envelope is empty, spending in that category stops for
  the month.
- **Pay Yourself First**: Automate savings and investment contributions so they
  leave your account before you have a chance to spend them.
- **Rolling Budget**: Carry forward unspent amounts in variable categories to
  the next month, smoothing out irregular expenses over time.

## Best Practices
- Review and adjust the budget monthly. Life changes and so should the budget.
- Track every transaction for at least 90 days to establish baseline spending
  patterns before setting category limits.
- Build buffer categories for irregular but predictable expenses such as car
  maintenance, annual subscriptions, and holiday gifts.
- Use percentage-based allocations rather than fixed dollar amounts so the
  budget scales automatically with income changes.
- Keep the number of categories manageable. Ten to fifteen categories is usually
  sufficient. Too many categories create tracking fatigue.
- Automate recurring bills and savings contributions to reduce decision fatigue.
- Schedule a weekly 15-minute money check-in to review spending against plan.

## Common Patterns
- **The Starter Budget**: Begin with three broad categories (needs, wants,
  savings) and refine over time as awareness grows.
- **The Irregular Income Budget**: For freelancers or commission-based earners,
  budget based on the lowest expected monthly income and treat surplus months
  as opportunities to build reserves.
- **The Debt Payoff Budget**: Temporarily compress discretionary spending to
  maximize debt repayment velocity. Rebalance once debt is eliminated.
- **The Couples Budget**: Maintain shared accounts for joint expenses and
  individual discretionary funds to preserve autonomy within partnership.
- **The Seasonal Budget**: Adjust allocations quarterly to reflect seasonal
  variations in utilities, activities, and income patterns.

## Anti-Patterns
- Setting an unrealistically tight budget that cannot be sustained. This leads
  to frustration and abandonment of the entire budgeting practice.
- Failing to account for irregular expenses, which causes budget-breaking
  surprises throughout the year.
- Treating the budget as purely restrictive rather than as a tool for enabling
  the spending that matters most.
- Obsessing over small daily expenses while ignoring large fixed costs that
  have far greater impact on overall financial health.
- Budgeting without clear financial goals. Without purpose, budgeting becomes
  an exercise in accounting rather than a tool for building the desired life.
- Sharing a budget system that only one partner understands or controls.
- Never revisiting category allocations even when circumstances change
  significantly.
