Delivery and disposal
Dump fees, haul-away, delivery, and equipment transport can sit outside material pricing.
Project planning
Use the prices and labor assumptions you actually have. The calculator adds the pieces together and makes contingency visible.
Project cost estimator
Enter your own local material and labor assumptions instead of relying on a national-average price.
Home projects often expose small unknowns after work begins. Contingency is not a prediction that something will go wrong; it is a planning allowance applied to the known-cost subtotal after materials tax, labor, permits, and miscellaneous costs. Straightforward, well-scoped work may need less. Renovation, demolition, hidden conditions, or old construction may justify more. This tool caps the entered tax rate at 20% and contingency at 50% to prevent accidental extreme entries.
Better than a single national average
Labor rates, material choices, taxes, delivery, disposal, and permit costs can differ dramatically. A single national average may be useful for orientation, but it can be a poor budget. This tool starts with the numbers you can verify locally.
If you only have a contractor quote and are deciding whether the work is worth doing yourself, use the DIY vs. hire calculator.
Example
With $1,200 of materials, 6% material sales tax, 16 labor hours at $85/hour, $100 of delivery or disposal, and a 10% contingency, the planning estimate is about $3,005. The important part is not that number itself; it is seeing exactly where the total came from so you can replace any assumption with a local quote or known cost.
The calculator applies contingency after the known-cost subtotal. It does not automatically add financing costs, contractor markup, insurance deductibles, or project-specific permit fees unless you enter them.

Requirements vary by project and jurisdiction. Verify them locally rather than guessing.
Fasteners, blades, adhesives, tape, protection, and cleanup supplies add up.
A planning allowance helps prevent a small surprise from breaking the entire budget.
