| Automation reduction | 35% | Workflow automation estimate |
| Total annual benefit | $171,103.75 | Combined yearly savings |
| First-year cost | $37,500.00 | Subscription, setup, training, support |

| Payback period | 3.00 months | Fast recovery of initial investment |
Formula Used
1) HR labor savings
HR hourly cost = Average HR annual salary ÷ Working hours per year
Current manual hours = Employees × Manual HR admin hours per employee
Labor savings = Current manual hours × Automation reduction × HR hourly cost
2) Payroll and compliance savings
Payroll error savings = Payroll errors per year × Cost per payroll error × Error reduction
Compliance savings = Compliance incidents per year × Cost per incident × Compliance reduction
3) Retention and hiring savings
Employees retained = Employees × Turnover rate × Turnover reduction
Retention savings = Employees retained × Cost per turnover
Hiring speed savings = Annual hires × Days reduced per hire × Vacancy cost per day
4) Productivity value
Productivity savings = Employees × Average employee salary × Productivity gain × Productivity capture
5) Core financial outputs
Total annual benefit = Labor + Error + Compliance + Retention + Hiring speed + Productivity savings
First-year ROI % = ((Total annual benefit − First-year cost) ÷ First-year cost) × 100
Payback months = First-year cost ÷ ((Total annual benefit − Recurring annual cost) ÷ 12)
NPV = Sum of discounted yearly net cash flows across the selected analysis period

FAQs
1. What does this calculator measure?
It estimates the financial return from HR software by combining labor savings, fewer payroll mistakes, lower compliance risk, retention gains, faster hiring, and captured productivity improvements.
2. Why include productivity capture percentage?
Not every time gain becomes cash value. Capture percentage lets you model how much of the productivity improvement actually turns into measurable financial benefit.
3. Should I use salary or fully loaded cost?
Fully loaded cost is usually better because it includes benefits, taxes, and overhead. That makes the savings estimate closer to the true economic impact.
4. How should I estimate turnover cost?
Include recruiting spend, vacancy impact, onboarding time, manager effort, and lost productivity during ramp-up. Many teams underestimate this value, which can hide real ROI.
5. What if my payback does not appear?
That means ongoing net benefit is zero or negative. Recheck your savings assumptions, recurring costs, or expected adoption level before making a decision.
6. Why does the calculator show multi-year ROI and NPV?
First-year ROI is useful for approval, but multi-year ROI and NPV show longer-term investment quality and the time value of money.
7. Can I use this for any currency?
Yes. Enter the currency symbol you want and keep every money input in the same currency. The ratio results remain valid regardless of symbol.
8. How accurate are the results?
The output is only as accurate as your assumptions. Use recent internal data, conservative ranges, and scenario testing for more reliable investment decisions.
