Cold Patch Asphalt Calculator

Estimate cold-patch bags for a pothole or patch using the coverage or compacted yield on your product label. You can also check hot-mix patch weight.

Cold Patch Asphalt Calculator

Use dimensions, a round pothole diameter, or a total area you already measured.

Package weight does not set product coverage. It is used for package weight totals, and with the Density method it also determines package count.

Example: 4

Example: 3

Example: 2

Follow the product instructions for minimum depth and lift thickness.

For cold mix, copy the coverage or compacted yield from your bag. Hot mix uses density for a planning weight check.

Copy the compacted yield from the selected package or data sheet.

Example: 0.5

Copy the compacted yield from the selected package or data sheet.

Cold Patch Bag Calculator: How Many Bags Do I Need?

Measure the pothole or patch after removing loose edges and debris. Enter the compacted depth, not the fluffy depth before tamping. The calculator separates compacted volume from order volume; waste increases the order quantity only.

Cold mix uses the coverage or compacted yield printed on the bag. Hot mix uses a supplier or tested density to convert volume into planning weight and tons.

Use the number printed on the bag. Common label formats include 0.5 cu ft per bag or 6 sq ft per bag at 1 in. The calculator accepts both formats directly, so you do not need to convert area-at-depth coverage to cubic feet by hand.

Follow the product instructions for minimum thickness, maximum lift thickness, weather limits, and compaction. For preparation and application steps, see how to patch an asphalt driveway pothole. A calculator cannot tell whether the base below the repair is stable.

Cold Patch Coverage by Square Feet and Depth

Coverage varies by product. The table below is an example for a package whose label states 0.5 cu ft of compacted yield.

At that example yield, one package covers about 6 square feet at 1 inch deep or 3 square feet at 2 inches deep before waste. Do not infer 0.5 cu ft from bag weight alone; use the compacted yield or coverage printed on your product.

Swipe or scroll horizontally to see more columns.

Compacted depth Example coverage per 0.5 cu ft package Example coverage with 10% waste
1 in 6.0 sq ft 5.5 sq ft
2 in 3.0 sq ft 2.7 sq ft
3 in 2.0 sq ft 1.8 sq ft
4 in 1.5 sq ft 1.4 sq ft

Patch bags vs bulk hot mix

For a full driveway, lane, or parking lot, use the asphalt tonnage calculator. For narrow cracks measured in linear feet, use the asphalt crack filler calculator. For contractor installation or replacement budgets, use the asphalt driveway cost calculator.

FAQ

How many bags of cold patch asphalt do I need?

Measure the repair area and compacted depth, then use the compacted yield or coverage printed on your bag or technical data sheet. The calculator adds any waste allowance, converts the label data to an equivalent compacted yield when needed, and rounds up to whole packages.

How much area does a 50 lb bag of asphalt patch cover?

There is no universal coverage for a 50 lb bag because products have different densities and compacted yields. Use the coverage or volume yield printed on the specific bag or technical data sheet; the calculator accepts either format instead of inferring coverage from bag weight.

Can I calculate cold patch bags from square feet?

Yes. Choose Enter total area, enter the repair square footage and compacted depth, then enter the coverage or yield from the bag.

What yield should I enter?

Use the compacted yield from the bag or technical data sheet. If the label gives square feet at a stated depth instead, choose Area covered at a stated depth and enter those two label values directly.

Can I use this for pothole repair?

Yes. Choose Circle / pothole for a round repair, Rectangle / trench for a cut-back patch, or Enter total area when you already know the repair square footage.

Can I use this for cracks?

This page is for potholes and patches with measurable width and depth. Narrow cracks usually need a crack filler or sealant made for that joint width.

Can I estimate hot-mix patch weight here?

Yes. Choose Hot mix, enter the compacted depth, waste allowance, and a supplier or tested density. The result separates compacted volume from order volume and shows planning weight and tons.

When should I use the asphalt tonnage calculator instead?

Use the asphalt tonnage calculator for larger hot-mix paving areas that are ordered by the ton. Use this page for a measured patch where you need packaged cold-patch bags or a focused hot-mix quantity check.
