Short Answer
A machinery ROI analysis should use verified investment, demand, good output, contribution, operating cost, downtime, working capital, collections and downside assumptions. A single payback number is not enough.
1. Define the scope
Include machine price, freight, duties where applicable, site work, utilities, tooling, software, training, initial spares, financing and working capital. State tax and currency treatment consistently.
2. Ask for evidence
Base revenue and savings on confirmed demand or explicit probabilities, realistic utilization and yield. Separate measured inputs from quotations, calculated values and management assumptions.
3. Set acceptance criteria
Test the case at lower utilization, slower ramp-up, exchange-rate movement, higher consumables, downtime and delayed collection. Define the threshold that would modify or stop the investment.
4. Normalize cost
Compare cash flow, payback, net operating benefit and cost per good part using one time horizon. Do not count the same labor, scrap or outsourcing saving twice.
5. Control risk and access
Assign owners for demand, technical output, cost, financing and collections. After startup, compare actual good output, downtime, cost, sales and cash collection with the approved case.
Frequently Asked Questions
What should be fixed before proposals are compared?
The required scope, evidence, acceptance result, exclusions, owner and review date.
Is the lowest price automatically the best option?
No. Compare total cost, operational risk and the ability to prove the required outcome.
What is the next practical step?
Share the proposed investment, expected jobs, prices, costs, utilization and payment assumptions for a controlled ROI model.
