Industrial Cleaning, Washing & Parts Cleanliness calculator
Cleaning Process Return Calculator
Estimate an undiscounted study-period return for a cleaning process improvement. Enter investment, annual gross savings, annual support and evaluation years.
What this calculator does
- Compare constant cleaning savings and support costs with an upfront investment over your chosen horizon.
Formula used
- Annual net savings = Annual gross savings − Annual support
- Net study value = Annual net savings × Horizon − Investment
- Study-period return % = Net study value ÷ Investment × 100
Inputs explained
- Cleaning Improvement Investment: Upfront capital and implementation amount for this comparison.
- Annual Gross Savings: Expected recurring savings before annual support costs.
- Annual Support Cost: Incremental annual support expense excluded from gross savings.
- Evaluation Horizon: Undiscounted study duration using constant annual cash flows.
How to use the result
- Best suited to cleaning investment screening, support cost sensitivity.
- Taxes, discounting, inflation and residual value are excluded.
Current U.S. benchmarks
- U.S. manufacturing runs at 75.7% of capacity (Federal Reserve, Aug 2026). New factory orders are up 8.5% year over year (Census).
Common questions
- Is this a discounted return? No. This screening calculation adds constant annual net savings without discounting their timing.
- Can annual net savings be negative? Yes. Support exceeding gross savings produces negative annual net savings and a loss-making study result.
- Is the horizon always five years? No. Enter the evaluation horizon relevant to your comparison; the historical five-year result label is not retained.
- Can this replace an investment appraisal? No. A full appraisal may need discounted cash flows, taxes, financing, residual value and uncertain savings scenarios.
