Contingency allowance

Applied to all listed costs.

Budget tip: Treat this as a planning worksheet, not a quote. Use current supplier prices and written contractor estimates, and check whether taxes, site preparation, waste removal, and permits apply to your project.

How this estimate works

The calculator adds materials, labour, delivery, equipment, permits, and other costs. It then applies your selected contingency percentage to that subtotal. If you enter a budget, the tool compares the estimated total with that amount.

Frequently asked questions

What is a contingency allowance?

It is an amount set aside for unexpected costs or changes. The appropriate percentage depends on how defined the scope is and how uncertain prices or site conditions may be.

Does this calculator convert currencies?

No. The currency field changes the displayed symbol or code only. Enter every cost in the same currency.

What costs are often forgotten?

Depending on the project, remember taxes, delivery, equipment hire, disposal, site preparation, permits, and finishing materials.
