How to use this renovation change order calculator

A few small upgrades can move a renovation budget quickly. Enter the original contract, approved additions, credits, pending changes, and payments to see where the project stands now.

What the calculator is showing you

Approved project cost is the original contract plus approved additions minus credits. Pending changes stay separate until you decide to approve them.

Potential total adds pending changes to the approved cost so you can see the possible impact before committing.

Remaining approved balance subtracts payments made from the current approved project cost. That number changes as approved changes change the project price.

Why not just use the original contract amount?

The original contract remains an important baseline, but it stops representing the current project price as soon as approved work changes. Keeping both numbers visible lets you see how far the project has moved without losing the original reference point.

Stop recalculating it by hand
