Using the Change Order Payment Calculator

When you add a change order to a proposal, the payment plan will need an update. Once you’ve created your change order, you can set a new down payment amount and adjust the number of payments if the added cost requires it. The Change Order Payment Calculator is here to make your life easier whenever a change order affects the payment plan you originally set up. Change orders can get complicated fast, and this tool helps you stay organized, both for yourself and for your client.

By using the calculator, you eliminate mistakes and confusion, making sure every change is accurate and easy to track. It also saves you time by handling the math for you, so you don’t have to spend long evenings recalculating totals or worrying about whether the numbers are fair, correct, and aligned with your profit goals.

To make your adjustments, use the Change Order Payment Calculator under the package selection area. 

You can edit by:

1. Changing the down payment percentage.

Enter the percentage you want to collect for the change order. If you don’t need a down

payment, just enter 0.

2. Adding extra payments (if needed).

Under Additional Payments, enter how many new payments you want to add to the original schedule. If you don’t want to add any, enter 0.

In the right hand column, you’ll see values labeled Remaining Balance, Progress Payments, and Final Payment. Here’s how the math works: the calculator simply divides your Remaining Balance (the original remaining balance from the proposal + the cost of the change order) by the updated number of payments to find the cost of each payment with the change order factored in.

Once you’re finished here, you can finalize and send your proposal to the client for package selection. When you show the change order to your customer, they’ll see a clear price breakdown, including:

● Total change order cost with tax

● Remaining payments on the original proposal

● Any new payments added

● Amount paid to date

● Change order down payment (if applicable)

● Updated remaining balance

● Amount for each progress payment

● Final payment amount (this may differ from other payments)

After everything looks good and the client approves, just proceed with the standard Client
