Annual labor savings = Employees × Hours saved per employee each month × 12 × Hourly rate.
Annual payroll base = Employees × Monthly work hours × 12 × Hourly rate.
Annual productivity value = Annual payroll base × Productivity gain percent ÷ 100.
Retention savings = Reduced turnovers per year × Replacement cost per employee.
Absence savings = Absenteeism days saved × Cost per absent day.
Total annual benefits = Labor savings + Productivity value + Retention savings + Absence savings + Error reduction savings + Other annual benefits.
One-time costs = Implementation cost + Training cost.
Annual recurring costs = Software cost per year + Admin cost per year + Other annual costs.
Year 1 B/C ratio = Total annual benefits ÷ Total year 1 costs.
ROI = (Total annual benefits − Total year 1 costs) ÷ Total year 1 costs × 100.
Discounted B/C ratio = Discounted benefits ÷ Discounted costs across the selected analysis years.
This B/C calculator helps HR and People Ops teams translate program ideas into measurable financial outcomes. Instead of reviewing benefits and costs separately, the page combines labor savings, productivity lift, turnover reduction, absence reduction, and error savings into one structured model.
The B/C ratio shows how much benefit is produced for each dollar spent. A ratio above 1 suggests benefits exceed costs. The ROI output highlights the size of the return, while the payback period shows how quickly the initial and recurring costs can be recovered through annual value creation.
The discounted view adds another planning layer. When you choose a discount rate and analysis period, the calculator estimates multi-year value using present-value logic. That helps teams compare projects more fairly, especially when costs happen early and benefits continue over time. Use the example table as a starting point, then replace the values with your own staffing, compensation, and program assumptions.
B/C means benefit-to-cost. It compares total benefits with total costs. A value above 1 means the initiative produces more benefit than cost.
It works for training programs, automation projects, wellness efforts, recruiting tools, retention plans, and process improvements that create measurable savings or productivity gains.
Enter values as requested by each field. Monthly time savings are annualized automatically. Most other benefit and cost fields on this page are yearly values.
Include implementation, training, software, administration, and any extra recurring expenses. The better your cost capture, the more reliable the B/C ratio becomes.
Use a conservative estimate first. Then run several cases with low, medium, and high assumptions to see how sensitive the decision is.
It adjusts future benefits and costs to present value. That makes long-term initiatives easier to compare with projects that pay off sooner.
Yes. Enter the employee count covered by the pilot and only the benefits and costs that belong to that smaller scope.
Payback period estimates how many months are needed for annual benefits to recover the first-year cost amount used in the model.
