NDIA claim efficiency calculator

This calculator shows how much time your team spends preparing NDIA claim lines and fixing rejected ones each month, using your own numbers. It then estimates what a pre-check and a generated claim file could change, with every assumption shown and editable. It is an estimate, not a promise.

Your figures

Use your own numbers. Nothing you type is stored unless you ask for the full results.

Claim lines a month

Lines in your bulk payment requests and invoices. An example value; use your own.

Minutes to prepare each line now

Looking up the item, checking the price and typing it in.

Lines rejected now

From your recent remittances.

Minutes to fix and resubmit a rejected line

Cost of an hour of office time

Pay plus on-costs such as super. An example value; use your own.

Average value of a claim line

Used to show how much payment rejected lines hold up.

Assumptions

What you expect to change. Every figure here is an assumption you can edit, not a promise.

Preparation time saved by a generated claim file

Your assumption. Change it to what you expect. Default: 70%, an estimate you can change.

Fewer rejected lines after a pre-check

Your assumption. Change it to what you expect. Default: 50%, an estimate you can change.

Your estimate

Time on claims now: 18.3 hours a month; Preparing lines and fixing rejected ones
Rejected lines now: 20 a month

The full results show the value of the time, a breakdown and the working.

How this is worked out

Rejected lines = 400 × 5% = 20 a month
Hours now = 400 × 2 min + 20 × 15 min = 18.3 hours a month
Hours after = preparation less 70% + 10 rejected lines (50% fewer) × 15 min = 6.5
Saved a year = (18.3 − 6.5) × 12 = 142 hours, worth $6,390 at $45 an hour

These are estimates from your figures and your assumptions. They are not a quote or a promise.
