For each position, multiply value by completion, add eligible stored material, deduct earlier amounts before tax and retention, add tax, then deduct the agreed retention. This assumes a constant retention rate across applications; it does not model retention caps or releases.
One contract, one application. A live job carries far more lines than these, the percentages move every month, and the cumulative total has to agree with every application already issued.
Questions about Progress billing and payment claim calculator
How do I calculate an Australian progress claim?
Select Australia to use AUD and a starting GST rate of 10 %. Enter completed work, eligible stored materials and previous amounts billed before tax and retention. Set the retention rate and basis from your contract; the profile starts at 0 % retention. Adjust GST if a different treatment applies. Security of payment requirements vary by state or territory, so the calculated amount still needs the claim documents required for your project.
Can I calculate a New Zealand payment claim?
Yes. Select New Zealand to use NZD and a starting GST rate of 15 %. Retention starts at 0 % because withholding it depends on the contract; enter the agreed rate and basis if applicable. Adjust GST to suit the work. The calculator gives the amount due. A payment claim under the Construction Contracts Act 2002 must also include the prescribed Form 1; this calculator does not generate that form.
What is the difference between G702 and G703?
G702 is the one-page application and certificate for payment, signed by the contractor and certified by the architect. G703 is the continuation sheet behind it, listing every line of the schedule of values with its scheduled value, work completed, stored materials and retainage. The G703 totals feed lines 4 and 5 of G702.
How much retainage can be withheld?
Retainage is a contract term, most often five or ten percent of the work in place. Many states cap it on public work, and several require it to stop or drop once the job passes a defined stage, so the rate written into the contract has to be checked against the statute where the project sits.
Can materials stored off site be billed?
Only if the contract says so. Column F on G703 is written for materials suitably stored, and many owners restrict that to material on site, or ask for a bill of sale, proof of insurance and photographs before certifying it. Enter stored material here only when your own contract allows the claim.
