Financing payment is principal and interest only. Actual borrowing may include lender fees, variable rates, liens, contractor financing terms, prepayment rules, or underwriting limits.
Methodology notes
Base paving cost
Base paving cost is driveway square footage times material and labor cost per square foot. Labor is adjusted by the complexity or slope multiplier.
Prep, drainage, and contingency
Demolition, grading, base prep, drainage, sealing or finishing, and permits are added before contingency. Contingency is applied to the pre-contingency subtotal.
Cash and financing
Cash gap compares the total project budget with cash available. If there is a shortfall, the calculator estimates the monthly payment on the financed portion using standard amortization.
Actual driveway costs depend on contractor quotes, local labor rates, material grade, pavement thickness, base depth, soil, excavation, demolition, drainage, slope, access, utility conflicts, tree roots, permits, inspections, freeze/thaw exposure, curing or sealing timing, paver maintenance, and lender terms. See full disclosure.
Driveway paving FAQ
What contingency should I use?
Simple flat resurfacing may fit 10% to 15%. Full replacement, poor drainage, uncertain base depth, slopes, pavers, tree roots, or permit risk may justify 20% or more.
Should I replace the base?
If the old driveway failed from settling, cracking, frost heave, or water problems, resurfacing over the same base can repeat the failure. Ask contractors to specify base depth and compaction.
How long until I can use it?
Timing varies by material and weather. Asphalt usually has shorter first-use restrictions than concrete, while concrete needs curing time before heavy loads. Confirm timing in the contract.
