Budget Variance
The difference between planned and actual spending
What You Need to Know
Budget variance measures how much your actual spending differs from your planned budget. Positive variance means you spent less than planned (good), while negative variance means you overspent. Tracking variance helps identify spending patterns and improve budget accuracy over time.
Types of Variance:
Positive Variance (Good):
- Spent less than budgeted
- Money left over for savings
- Indicates good spending control
- Example: Budgeted $500 for groceries, spent $450
Negative Variance (Concerning):
- Spent more than budgeted
- May indicate overspending
- Could lead to debt
- Example: Budgeted $200 for dining out, spent $300
Common Causes of Variance:
- Underestimating costs: Didn't account for all expenses
- Impulse spending: Unplanned purchases
- Price changes: Inflation, rate increases
- Life changes: New job, family, health issues
- Seasonal expenses: Holidays, vacations, back-to-school
How to Track Variance:
- Record actual spending
- Compare to budget monthly
- Calculate percentage variance
- Identify patterns and causes
- Adjust budget for next month
Improving Budget Accuracy:
- Track spending for 2-3 months first
- Include irregular expenses
- Build in buffer for unexpected costs
- Review and adjust monthly
- Use past data to predict future costs
Example:
- Budgeted: $1,000 for housing
- Actual: $1,050
- Variance: -$50 (-5%)
- Action: Adjust budget or reduce other expenses
