Model filtration upgrades, absenteeism savings, and energy impacts for teams. Test assumptions quickly across scenarios. Turn healthier spaces into clearer budgets and stronger returns.
The chart compares cash flow timing with cumulative financial return.
| Metric | Example Value | Meaning |
|---|---|---|
| Occupants | 120 | Total people affected by the air quality improvement. |
| Initial investment | $51,500 | Upfront spending for equipment, sensors, and installation. |
| Sick days reduction | 1.3 days per employee | Recovered workdays due to healthier indoor conditions. |
| Productivity gain | 1.8% | Estimated performance uplift from better concentration and comfort. |
| Retention gain | 0.8% | Reduced turnover linked to improved workplace experience. |
| Discount rate | 8% | Used to discount future savings into present value. |
It estimates the financial return from air quality upgrades by combining absenteeism savings, productivity gains, retention benefits, healthcare savings, operating impacts, payback, and net present value.
Fewer sick days mean more productive labor hours. The calculator values recovered days using annual salary and workdays, turning health improvements into measurable labor savings.
The tool multiplies total salary spend by the estimated productivity improvement percentage. Even small gains can create large annual value in offices with many employees.
Enter the estimated yearly increase or decrease in utility cost after the upgrade. Higher filtration may raise fan energy, while smarter controls may lower total use.
ROI shows annual return relative to upfront cost. NPV discounts future cash flows into today's value, which helps compare long-term projects more realistically.
Healthier and more comfortable workplaces may reduce turnover. Lower replacement hiring and training costs can materially improve the business case for air quality investments.
Use your organization’s hurdle rate, weighted capital cost, or another internal benchmark. A higher discount rate reduces the present value of future savings.
Yes. Run different scenarios for filtration levels, sensors, and costs. Then compare payback, annual benefits, and NPV to choose the strongest option.
