Aviation MRO ROI Calculator

Put your own numbers in on the left. The results update as you type, and every figure below shows the arithmetic behind it so you can check the working or argue with it.

Two kinds of number go into this. The ones marked published come from figures Impresa has put in writing. The ones marked yours are yours to set, and nobody else can set them honestly. Every improvement rate can be dragged to zero. If you set them all to zero the answer is zero, which is the point.

Your operation

Six numbers your shop already knows.

Technicians on the floor

Fully loaded labour rate, per hour Wages plus benefits, tax and overhead. Not the rate you bill.

Hours per technician per week on admin Chasing paperwork, looking for parts status, re-keying the same data.

Work orders completed per month

Average revenue per work order

Contribution margin on extra work

What you keep on an extra job 35%

What you expect to improve

Drag any of these to zero to take it out of the answer.

Turnaround time reduction published 23%

Impresa publishes 23% on a named aerospace and defence customer, and up to 30% as its stated ceiling. Anything above 30% is not a claim Impresa has made.

Freed capacity you could actually sell yours 50%

Shorter turnaround only earns money if there is work waiting for the slot it opens up. If your backlog would not fill it, drag this down. Most calculators skip this question, which is why most calculators flatter the answer.

Admin time reduction yours 25%

There is no published Impresa figure for this. The default is a placeholder, not a claim. Set it to what you believe.

Shipped work sitting uninvoiced, at any one time yours Work that has left the building but has not been billed. Most shops do not know this number, which is the reason it is worth finding. Leave it at zero if you would rather not guess.

Share of that you would recover 60%

Estimated annual benefit

Based on the numbers on the left.

Technician hours returned

per year, across the floor

Extra work orders

same people, same building

Throughput gain

Where the benefit comes from

Three separate effects. They do not overlap, so they add.

Payback

This is the one number the calculator cannot fill in for you, because it depends on what you are quoted. Put the annual figure in and it will work out the rest.

Want this as a PDF?

The results are already on screen and stay there. If it is useful to have a copy with your numbers in it to send round internally, leave an address and we will send one.

Every figure here is an estimate built from the numbers you entered. The turnaround reduction is drawn from published Impresa results at other operators and is not a forecast for your shop. Nothing you type is stored unless you ask for the PDF.
