Calculator Use

Maintaining your asphalt is critical for curb appeal and longevity. Use this driveway sealing cost calculator to estimate the financial investment required to protect your driveway from the elements. This tool allows you to calculate by dimensions (Length & Width) or by providing a total square footage measurement. By inputting current material and labor rates, you can generate a realistic quote for professional services or DIY planning.

Driveway Dimensions
Enter the length and width of your driveway in feet to find the total area. For irregular driveways, it is often best to measure the total area in square feet manually.
Material Cost per Sq Ft
The cost of sealcoat varies by quality. Standard asphalt emulsion typically ranges from $0.15 to $0.25, while premium oil-based sealers can reach $0.40 or more per square foot.
Labor Cost per Sq Ft
Professional labor usually accounts for cleaning the surface, edging, and applying the sealant. National averages for labor range between $0.25 and $0.50 per square foot depending on local demand and driveway condition.

How It Works

When you estimate your project, the driveway sealing cost calculator follows a standardized formula used by most paving contractors. The core of the calculation is determining the surface area and applying a "per square foot" rate that covers both consumables and professional effort.

Total Cost = Area in Sq Ft × (Material Rate + Labor Rate)

  • Area: Measured in square feet (Length × Width).
  • Material Rate: The price of the sealer, usually purchased in 5-gallon buckets.
  • Labor Rate: The professional fee for application, or $0 if you are performing a DIY job.
  • Subtotal: The sum of materials and labor before any applicable taxes or specialized repair costs.

Calculation Example

Example: A standard two-car driveway that is roughly 20 feet wide and 40 feet long using mid-grade sealant.

Step-by-step solution:

  1. Calculate Area: 40 ft (Length) × 20 ft (Width) = 800 sq ft
  2. Determine Material Cost: 800 sq ft × $0.20 = $160.00
  3. Determine Labor Cost: 800 sq ft × $0.35 = $280.00
  4. Add Totals: $160.00 + $280.00
  5. Final Result = $440.00

Common Questions

How often should I use a driveway sealing cost calculator?

You should plan for sealing every 2 to 3 years. Use the calculator to budget for this maintenance every couple of years as material prices often fluctuate with oil markets. Sealing more frequently can lead to a buildup of sealant that may crack or peel.

What factors increase the final cost beyond the calculator's estimate?

The calculator provides a baseline for sealing. However, significant crack repair, pothole filling, or intensive cleaning (such as removing large oil stains) will add to the total. Most contractors charge between $1.00 and $2.00 per linear foot for crack repair.

Is it cheaper to seal a driveway myself?

Yes, by setting the Labor Cost to $0 in the driveway sealing cost calculator, you can see the DIY price. While you save on labor, keep in mind you will need to purchase tools like a squeegee, broom, and protective gear, which are one-time costs not factored into the per-square-foot material price.

Choosing the Right Sealant

When using the calculator, your material input will depend on the product type:

  • Asphalt Emulsion: The most common and environmentally friendly option. Excellent for UV protection.
  • Coal Tar: Very durable and resistant to gas/oil spills, but contains high VOCs and is restricted in some states.
  • Oil-Based: Penetrates the asphalt to replenish lost oils. Generally more expensive but highly effective for older driveways.
