How this calculator works

This calculator adds a transparent planning contingency to a stated estimate cost without representing it as a final-price prediction.

Enter the current project cost basis.
Set a contingency percentage that is explicitly documented for planning.
Keep contingency visible as its own line in a professional estimate.

Worked example: Example: a $10,000 estimate with 10% contingency reserves $1,000, for a planning total of $11,000 before separately treated markup, discount or tax.
