How Actual vs Budgeted Fuel Calculator Works
This tool works by comparing recorded fuel spending with the planned budget and splitting the difference into a price effect and a volume effect.
- Step 1
Enter the budget
Type the budgeted gallons or liters and the budgeted price.
- Step 2
Enter the actuals
Type the fuel volume bought and the average price paid.
- Step 3
Calculate the variance
The calculator subtracts budgeted cost from actual cost.
- Step 4
Read the causes
The calculator splits the variance into price variance and volume variance.
Actual vs Budgeted Fuel Calculator Formula
The formula splits total variance into a price part and a volume part.
Total Variance = Actual Cost − Budgeted Cost
Price Variance = (Actual Price − Budget Price) × Actual Volume
Volume Variance = (Actual Volume − Budget Volume) × Budget Price
- Price Variance
- = cost change from paying a different price
- Volume Variance
- = cost change from buying more or less fuel
Worked Example
- Budget: 45 gallons at $3.40 = $153.00. Actual: 49 gallons (185.5 L) at $3.62 = $177.38.
- Total variance = $177.38 − $153.00 = +$24.38 over budget.
- Price variance = ($3.62 − $3.40) × 49 = +$10.78.
- Volume variance = (49 − 45) × $3.40 = +$13.60. More driving caused most of the overspend.
Actual vs Budgeted Fuel Calculator Conversion Table
The table compares 6 months of actual fuel spending with a budget of 45 gallons at $3.40 ($153.00) per month.
| Month | Actual gal (L) | Actual Price | Actual Cost | Total Variance | Price Variance | Volume Variance |
|---|---|---|---|---|---|---|
| Jan | 44 (167) | $3.31 | $145.64 | -$7.36 | -$3.96 | -$3.40 |
| Feb | 46 (174) | $3.38 | $155.48 | +$2.48 | -$0.92 | +$3.40 |

| Jun | 45 (170) | $3.44 | $154.80 | +$1.80 | +$1.80 | +$0.00 |
What is an Actual vs Budgeted Fuel Calculator?
An Actual vs Budgeted Fuel Calculator is a variance tool that compares recorded fuel spending with planned spending and explains the gap.
A budget miss has 2 causes: higher prices or more fuel. Drivers control fuel volume but not prices. The Actual vs Budgeted Fuel Calculator separates the 2, so the response fits the cause: change driving for volume variance, adjust the budget for price variance.
Finance teams use the same method for fleet fuel reports.
What are the uses of an Actual vs Budgeted Fuel Calculator?
There are 4 main uses of the Actual vs Budgeted Fuel Calculator, including monthly reviews, fleet reporting, and budget resets.
Review each month
See whether price or driving caused a miss.
Report fleet variance
Give finance a price and volume breakdown.
Reset the budget
Raise the budget price after lasting price changes.
Target driving habits
Act on volume variance with route and idling changes.
