A good driveway bid does two things. It wins the job. And it makes you money. Here is how to build one in five steps.
Step 1: Measure the job
Get the length, the width, and the thickness. Most driveways for cars and pickups are poured 4 inches thick. Many crews go 5 or 6 inches where heavy trucks or RVs will park.
Example: a driveway 40 feet long and 20 feet wide is 800 square feet.
Step 2: Figure your yards
Length × width × thickness (in feet) ÷ 27 = cubic yards. Four inches is 0.333 feet.
40 × 20 × 0.333 ÷ 27 = 9.88 yards
Add 10% so you don't run short. That is 10.86 yards. Order 11.
Step 3: Add up every cost
These are example numbers. Use your own.
| Cost | Amount |
|---|---|
| Concrete, 11 yards at $170 | $1,870 |
| Gravel base, rebar, forms | $700 |
| Labor, 4 men × 8 hours × $35 | $1,120 |
| Fuel, blades, sealer | $150 |
| Your total cost | $3,840 |
Don't forget tear-out, dump fees, a pump, or a short-load fee if the job needs them. Missed costs come out of your pocket.
Step 4: Add your margin the right way
Margin and markup are not the same thing. Mixing them up costs real money.
- Markup: $3,840 × 1.25 = $4,800. You keep $960. That is only 20% of the price.
- Margin: $3,840 ÷ 0.75 = $5,120. You keep $1,280. That is a true 25%.
Same job. A $320 difference. To hit a 25% margin, divide your cost by 0.75.
Step 5: Check your price per square foot
$5,120 ÷ 800 square feet = $6.40 a square foot.
