Asphalt Driveway Cost Calculator

Every thickness, density, allowance, rate and fee is an editable user input. Confirm the pavement section with qualified local professionals and use current supplier prices and written contractor quotes.

1. 1Choose Imperial or Metric measurements and select new driveway, replacement, or overlay and resurfacing.
2. 2Enter driveway length and average width, or enter a known measured area.
3. 3Enter the compacted asphalt thickness and density confirmed for the selected mix and project.
4. 4Choose an asphalt ordering allowance and optionally enter current price per ton or tonne.
5. 5Include aggregate base only when it belongs in the project scope, then enter its confirmed depth, density and allowances.
6. 6Enter optional excavation, removal, grading and paving-labor rates from current written quotes.
7. 7Add applicable edging, delivery, drainage, permit, disposal and other project costs.
8. 8Enter the applicable material-tax percentage and a planning contingency.
9. 9Review itemized quantities, subtotals, total project cost and cost per sq ft or m².

1. 1Driveway area = length × average width, or the known area entered by the user.
2. 2Imperial asphalt volume = area × compacted thickness in ft ÷ 27. Metric asphalt volume = area × compacted thickness in m.
3. 3Asphalt weight before allowance = compacted volume × supplier-confirmed density.
4. 4Asphalt order weight = base weight × (1 + asphalt ordering allowance ÷ 100).
5. 5Compacted base volume = area × entered compacted base depth.
6. 6Loose base volume = compacted base volume × (1 + compaction allowance) × (1 + waste allowance).
7. 7Base order weight = loose base volume × supplier-confirmed density.
8. 8Material cost = order weight × entered price per ton or tonne; edging uses entered length × entered linear-unit rate.
9. 9Area-based service cost = measured driveway area × entered local rate.
10. 10Materials subtotal = asphalt + aggregate base + edging. Services subtotal = preparation, labor and entered fixed costs.
11. 11Tax = priced-material subtotal × entered tax percentage.
12. 12Contingency = pre-tax direct subtotal × entered contingency percentage.
13. 13Estimated total = direct subtotal + material tax + contingency. Unit cost = total ÷ measured driveway area.

• Driveway dimensions describe a uniform measured area and do not model tapers, curves or separate thickness zones.
• Asphalt and base thicknesses are compacted finished thicknesses entered by the user, not recommendations.
• Asphalt weight uses the entered supplier-confirmed density and applies the ordering allowance once.
• Aggregate-base compaction allowance is applied once to compacted volume and handling waste is applied once afterward.
• Base weight uses the entered supplier density for the calculated loose order volume.
• Project type provides scope context and controls removal-field visibility but applies no hidden cost multiplier.
• Area-based rates use measured driveway area rather than waste-adjusted material area.
• Replacement removal cost appears only when replacement is selected and a rate is entered.
• Tax applies only to priced asphalt, aggregate base and edging as a planning convention; local taxability varies.
• Contingency applies to the pre-tax direct subtotal and does not predict concealed conditions.
• Blank optional costs contribute zero and do not mean the work is free, unnecessary or included elsewhere.
