Driveway Extension Cost Calculator: DIY vs Hiring a Pro by Material
Gravel, pavers, concrete or asphalt: DIY from $550, a contractor from $600 for a 10×20 strip.
- Pick the material, not a size: every option is priced for a 10×20 (200 sq ft) strip. For a bigger pad, scale the materials by area — a 12×40 RV pad is 2.4 times the numbers.
- On the DIY tab the plate compactor rental is in every material and shouldn't be unticked; the wet saw only appears for pavers, the floats only for concrete.
- Asphalt shows the pro cheaper because it's priced with bagged cold-mix — the only way to lay asphalt without a paving crew, and a bad one. The tab is honest about that on purpose.
- On the Hire a pro tab, tick the tie-in dowels for concrete, the curb-cut line if the extension reaches the street, and the permit if your city limits paving.

Typical results by job size
Defaults the calculator starts from: commonly owned tools excluded, typical pro price, no add-ons.
| Size | Verdict | DIY | Pro | Your hours | Typical savings | Break-even |
|---|---|---|---|---|---|---|
| Gravel | DIY | $550–$950 | $600–$1,500 | 8–14 hours | $250 (25%) | $23/hour |
| Concrete | Hire | $1,440–$1,840 | $1,600–$3,200 | 16–26 hours | $560 (25%) | $27/hour |
| Asphalt | Hire | $2,160–$2,560 | $1,000–$2,400 | 12–20 hours | pro is cheaper | — |
| Concrete pavers | DIY | $1,725–$2,125 | $2,400–$5,000 | 24–40 hours | $1,575 (45%) | $49/hour |
Break-even is what an hour of your time would have to be worth for DIY and hiring to cost the same. Above it, hiring is cheaper all-in. See how these are calculated.
Reading the result
The material you pick applies to both tabs, and every figure is for a 10×20 strip.
Do it yourself totals the delivered crushed stone and the surface material — gravel and edging; ready-mix, forms, rebar and joint hardware; cold-mix bags; or pavers, sand, restraint and polymeric sand — plus the plate compactor rental every material needs, the wet saw for pavers, the floats and trowels for concrete, safety gear, soil disposal, a permit where one applies, and your hours at the rate you set: 8–14 for gravel, 16–26 for concrete, 12–20 for asphalt, 24–40 for pavers.
Hire a pro starts from a low, typical or high installed price for that material on 200 sq ft, then adds what a bare quote often leaves out: removing sod or an old surface, extra excavation for roots or rock, a saw-cut and doweled tie-in for concrete, curb or apron work in the right-of-way, a channel or French drain, a decorative finish or border, sealer, and the permit and HOA fee. Tick what applies and compare.
What neither tab includes: whether you’re allowed to pave it. Impervious-cover caps, driveway-width limits and HOA rules aren’t a cost line — they’re a yes or a no — and the full comparison explains how to find out before you order stone. The DIY guide covers the paver and gravel builds where the DIY column is a real option.
Frequently asked questions
How do I size the calculator for my extension?
Multiply length by width for square feet and divide by 200 to get a scale factor, then multiply the DIY materials and the pro price by it — a 12×40 RV pad (480 sq ft) is 2.4×. The compactor rental and small tools don't scale much until the job passes 400 sq ft, when a second rental day and a skid steer for the dig start to make sense. Pro per-foot rates also fall a little as the job grows, so the scaled pro figure is a slightly high estimate on big pads.
Why does the asphalt DIY figure come out higher than hiring?
Because it's built from bagged cold-mix asphalt at $15–$22 per 50 lb bag: 200 sq ft at 2 inches is about 100 bags, $1,800 in material for a surface that never cures as hard as hot-mix. There's no homeowner access to hot-mix at this size — plants have minimum orders and the mix has to be laid and rolled within minutes of arriving. A paving crew at $1,000–$2,400 is the only real option, and the calculator shows it.
What do the quote levels mean for a driveway extension?
Low is a simple flat strip in an inexpensive market, done by a contractor who's already in the neighborhood, at the minimum spec. Typical is the national median for that material on 200 sq ft with excavation, a compacted base and a proper tie-in. High is a difficult site — slope, roots, poor drainage — a coastal metro, or an above-spec build (6-inch concrete, premium pavers). Decorative finishes, drains, curb work and the permit are add-ons on any level.
