Percentage of Budget Used
Calculate what percentage of your budget you've spent to track progress throughout the month.
=spent/budget How It Works
Dividing spent amount by budget gives you a decimal that represents the percentage used. Format as percentage to see how much of your budget remains.
Syntax
=spent / budget
Or for display: =TEXT(spent/budget, "0%")
Example
| Category | Budget | Spent | % Used |
|---|---|---|---|
| Groceries | $500 | $325 | 65% |
| Dining | $200 | $180 | 90% |
| Entertainment | $150 | $45 | 30% |
| Gas | $200 | $210 | 105% |
Formula in D2: =C2/B2
Format column D as percentage (Format → Number → Percent).
Progress Tracking
Pace Check
Are you on track mid-month? Compare percent of budget used to percent of month elapsed:
=spent/budget - DAY(TODAY())/DAY(EOMONTH(TODAY(),0))
- Negative result: Under budget (good)
- Positive result: Spending too fast
Visual Progress Bar
Create a simple text-based progress bar:
=REPT("█", MIN(10, ROUND(C2/B2*10))) & REPT("░", MAX(0, 10-ROUND(C2/B2*10)))
Result: ██████░░░░ (60% used)
Color Coding with Conditional Formatting
Make overspending obvious:
- Select the % Used column
- Format → Conditional formatting
- Add rules:
- Less than 0.75 → Green
- Between 0.75 and 1 → Yellow
- Greater than 1 → Red
Variations
Remaining Budget
Show what’s left instead of what’s used:
=(budget - spent) / budget
Or in dollars: =budget - spent
With Planned vs. Actual
For comparing planned spending to what actually happened:
=actual / planned - 1
Positive = over plan, Negative = under plan
Category as Percent of Total
What portion of total spending is each category?
=category_spent / SUM(all_spent)
Dashboard Summary
Create a quick budget health check:
| Metric | Formula |
|---|---|
| Total Budget | =SUM(Budget) |
| Total Spent | =SUM(Spent) |
| Overall % | =SUM(Spent)/SUM(Budget) |
| Categories Over | =COUNTIF(PercentUsed, ">100%") |
| Categories Under 50% | =COUNTIF(PercentUsed, "<50%") |
Pro Tips
-
Check weekly - catching overspending early gives you time to adjust
-
80% warning threshold - when a category hits 80%, slow down spending there
-
Track patterns - consistently hitting 100%+ means your budget may be unrealistic
-
Separate fixed vs. variable - fixed expenses should always be 100%; focus on variable categories
Common Errors
- #DIV/0!: Budget is $0 or empty - use
=IFERROR(spent/budget, 0)to handle - Shows decimal instead of %: Format the cell as Percentage
- Over 100% shows as error: This is correct! It means you overspent
