At our example rates, gravel costs about a seventh of what concrete does on the same driveway. That gap is the whole argument for gravel, and it is a strong one. The catch is that gravel is a subscription: regrading, top-up rock, weeds, and a fight with the snow plow. Concrete is a one-time check that mostly ends the conversation.
The up-front gap
A two-car driveway at 20 by 24 feet is 480 square feet. At the example rates:
| Surface | Example rate | 480 sq ft total |
|---|---|---|
| Gravel, 4 inch depth | $1.25 / sq ft | $600 |
| Gravel, 6 inch depth | $1.75 / sq ft | $840 |
| Concrete, broom finish | $9 / sq ft | $4,320 |
Example rates, not market prices. Rock, trucking, and concrete all price differently town to town. The gravel driveway cost calculator and the concrete driveway cost calculator show how each number builds.
What gravel asks from you every year
Gravel moves. Tires push it into ruts and washboard, rain cuts channels, and the surface slowly migrates into the yard. Regrading puts it back: at the example rate of $0.75 per square foot, one regrade of this driveway is $360, more than half the original 4 inch install, every time you do it.
Weeds come up through gravel unless fabric went down first (the example add-on is $0.35 per square foot, or $168 on this driveway). And if you plow, the blade drags rock into the lawn all winter and you rake it back every spring. None of this is a dealbreaker. It is just the honest ledger.
What concrete asks
Not much. Keep de-icing salt off it, maybe seal it now and then, and accept that someday a crack will show up. The slab keeps working either way. The trade is simple: you pay roughly seven times more up front, at these example rates, to stop thinking about your driveway.
Who should pick which
Gravel fits long rural runs, rentals, tight budgets, low daily traffic, and anyone planning to pave later, since compacted gravel can serve as the future base. Concrete fits the keep-forever house, daily traffic, snow country with weekly plowing, and buyers who value curb appeal. If asphalt is also on your list, read gravel vs asphalt driveway next.
