- Minivans average 26.5 MPG combined, actually slightly ahead of small/compact SUVs (26.1 MPG) and far ahead of midsize/large SUVs (19.6 MPG).
- At 12,000 miles per year and $3.10/gallon, a minivan costs $1,404 to fuel versus $1,425 for a small SUV and $1,898 for a midsize/large SUV.
- The fuel cost difference between a minivan and a midsize/large SUV is $494 per year in the minivan's favor; versus a small SUV it's roughly a wash ($21/year).
- Within each SUV class, models with 4WD/AWD average 1.3–3.3 MPG less than 2WD models, widening the gap further versus the mostly front-wheel-drive minivans.
01 Class Average Fuel Economy
Minivans average 26.5 MPG combined, slightly ahead of small SUVs (26.1 MPG) and far ahead of midsize/large SUVs (19.6 MPG), a gap worth $494 a year in fuel costs versus a midsize/large SUV at 12,000 miles/year. The EPA's vehicle-class taxonomy distinguishes minivans from "small" and "standard" sport utility vehicles (it does not track a separate midsize-vs-large split, or a 2-row-vs-3-row split, those are marketing terms, not EPA classifications). The table below shows the average combined MPG for each class, the number of vehicle configurations behind it, and the share that are front-wheel drive, computed directly from EPA data.
EPA/DOE, Fuel Economy Guide database, gasoline-fueled vehicles (including hybrids), model years 2024–2025| Vehicle Type | Avg Combined MPG | Configurations | Front-wheel drive |
|---|---|---|---|
| Minivan | 26.5 | 17 | 76% |
| Small / Compact SUV | 26.1 | 482 | 24% |
| Midsize / Large SUV | 19.6 | 362 | 5% |
The most direct comparison for families with three rows is between minivans and midsize/large SUVs. The EPA's standard sport utility class covers both two-row and three-row models, so the class average is not specific to three-row vehicles. Against that class average, minivans are about 6.9 MPG ahead.

Using 12,000 miles per year and $3.10 per gallon of regular gasoline, the annual fuel cost for each family vehicle category works out as follows.
Calculated: 12,000 mi ÷ class avg MPG × $3.10/gal. EPA/DOE Fuel Economy Guide MPG data; EIA, Short-Term Energy Outlook, September 2026, Table 2: Energy Prices; 2025 annual average regular gasoline retail price.| Vehicle Type | MPG | Annual Gallons | Annual Fuel Cost | Diff vs Minivan |
|---|---|---|---|---|
| Minivan | 26.5 | 453 | $1,404 | n/a |
| Small/Compact SUV | 26.1 | 460 | $1,425 | +$21 |
| Midsize/Large SUV | 19.6 | 612 | $1,898 | +$494 |
Compared to a small SUV, the minivan is essentially a wash, just $21 cheaper per year to fuel. But compared to a midsize/large SUV, the minivan saves $494 per year.

Use the Calculator03 The AWD Factor
Most minivan configurations in the data are front-wheel drive, while most SUV configurations are all-wheel or four-wheel drive. Comparing the EPA's "2WD" and "4WD" configuration codes within the same vehicle class (the closest available proxy for FWD vs AWD) shows a real fuel-economy penalty: within the small SUV class, 2WD models average 28.6 MPG versus 25.3 MPG for 4WD, a 3.3 MPG gap. Within the midsize/large SUV class, 2WD models average 20.7 MPG versus 19.4 MPG for 4WD, a 1.3 MPG gap.
EPA/DOE Fuel Economy Guide database, model years 2024–2025: comb08 by VClass, comparing 2WD vs 4WD configurations within each class; see also AWD vs 2WD fuel cost comparisonApplied to annual cost: a 2WD midsize/large SUV at 20.7 MPG costs about $1,797 per year to fuel, while a 4WD version at 19.4 MPG costs about $1,918 per year, both well above the minivan's $1,404, with the 4WD version costing $514 more per year than the minivan.
Calculated: $3.10 ÷ MPG × 12,000, using EPA/DOE Fuel Economy Guide 2WD/4WD class averages04 Five-Year Fuel Cost Difference
Over a typical five-year ownership period at 12,000 miles per year and $3.10 per gallon, the cumulative fuel cost differences between vehicle types become substantial.
Five-year projections based on annual fuel cost calculations above| Comparison | Annual Diff | 5-Year Difference |
|---|---|---|
| Minivan vs Small/Compact SUV | −$21/yr | −$105 |
| Minivan vs Midsize/Large SUV (all) | −$494/yr | −$2,470 |
| Minivan vs Midsize/Large SUV (4WD only) | −$514/yr | −$2,570 |
For families choosing between a minivan and a midsize/large SUV, the minivan saves roughly $2,470 in fuel over five years, more if the SUV is a 4WD/AWD model. Versus a small SUV, the fuel-cost difference is negligible either way. The choice ultimately depends on space requirements and other ownership priorities.
05 Beyond Fuel Cost
Fuel cost is one component of total ownership cost. This article does not compare insurance, depreciation, tires, cargo or passenger space, or towing, which vary by model and for which this site has no class-level federal data. For national average ownership costs beyond fuel, see the ownership cost panel in the calculator.
