Estimate how long an IoT sensor project may take to recover its initial investment. Combine hardware, installation, and setup costs, then compare them with annual labor savings, avoided losses, and recurring operating expense. The result shows simple payback, annual net benefit, and a five-year return estimate so you can test whether the economics remain workable before preparing a fuller cash-flow model.
Simple payback indicates when cumulative undiscounted net benefits equal the initial cost. A shorter period improves cost recovery, but it does not capture timing, taxes, financing, or residual value.
Use scenario-specific estimates. This planning tool is not an investment guarantee and does not replace a discounted cash-flow analysis.
With a $50,000 initial cost, $18,000 in labor savings, $12,000 in avoided losses, and $6,000 in annual operating cost, annual net benefit is $24,000 and simple payback is 2.08 years. Five-year simple ROI is 140%.
There is no finite simple payback; the calculator reports that annual net benefit must be positive.
No. It uses undiscounted annual net benefit and is intended as a simple screening measure.
Include expected annualized replacement and maintenance costs in annual operating cost.
It is five years of net benefit minus initial cost, divided by initial cost, expressed as a percentage.
Yes, if the value is evidence-based and not already included in labor savings or another benefit line.
| Input | Included amount |
|---|---|
| Initial project cost | Hardware, setup, installation, integration |
| Annual labor savings | Recurring labor benefit |
| Annual avoided losses | Prevented downtime, waste, or damage |
| Annual operating cost | Software, connectivity, maintenance, support |
