| Input Group | Field | Example Value |
|---|---|---|
| Investment | Equipment / Machine Cost | 150,000 |
| Investment | Installation / Commissioning | 25,000 |
| Benefits | Labor Savings (annual) | 42,000 |
| Benefits | Scrap / Rework Reduction (annual) | 15,000 |
| Benefits | Extra Profit from Capacity (annual) | 22,000 |
| Assumptions | Discount Rate | 10% |

Tip: adjust benefit realization and contingency to reflect uncertainty.
Formulas Used
These calculations follow common industrial capital‑budgeting practice.
- Total Initial Investment = (Equipment + Installation + Training + Integration + Other) × (1 + Contingency).
- Annual Benefits = (Labor + Energy + Maintenance + Scrap + Downtime + Extra Profit) × Benefit Realization.
- Straight‑line Depreciation = Total Initial Investment ÷ Project Life.
- After‑tax Cash Flow = (Benefits − Operating Costs) × (1 − Tax) + Depreciation × Tax.
- NPV = Σ [ CashFlowt ÷ (1 + DiscountRate)t ] for t = 0..N.
- IRR = rate where NPV = 0 (numerical solve).
- Payback = time when cumulative cash flow becomes non‑negative (linear interpolation).

FAQs
Quick answers for common manufacturing ROI questions.
1) What makes this calculator “industrial”?
It separates CAPEX, multiple savings streams, operating costs, taxes, depreciation, and risk adjustments. That structure matches real manufacturing project evaluations and approval workflows.
2) Should I use simple ROI or NPV?
Use NPV for investment decisions because it accounts for time value and discount rate. Simple ROI is useful for quick comparisons, but it can hide cash flow timing effects.
3) How do I choose a discount rate?
Many teams use a hurdle rate or weighted average cost of capital. If unsure, test several rates and compare NPVs to understand sensitivity and risk.
4) What is benefit realization, and why use it?
It reduces benefits to reflect ramp-up, adoption, and measurement uncertainty. Using 80–95% often produces more credible business cases than assuming perfect savings.
5) Does depreciation change project value?
Depreciation itself is non-cash, but it reduces taxable income. The calculator includes the depreciation tax shield, which can materially improve after-tax cash flow.
6) What if the IRR shows N/A?
IRR may be undefined if cash flows do not cross zero clearly, or if there are multiple sign changes. In those cases, rely on NPV, payback, and scenario testing.
7) How can I make the estimate more realistic?
Add conservative benefits, include all recurring costs, and apply contingency. Run best/base/worst scenarios by changing realization, downtime savings, and discount rate.
