Automation ROI Calculator

Estimate the financial return on your automation investment by comparing implementation costs against labor and efficiency savings over time.

Total Implementation Cost ($) Software, hardware, integration, and setup costs

Annual Maintenance & Licensing Cost ($/year) Ongoing support, subscriptions, and upkeep

Hours Saved Per Week (hours) Total manual labor hours eliminated per week

Average Hourly Labor Rate ($/hour) Fully loaded cost including benefits (typically 1.25–1.4× base wage)

Annual Error & Rework Cost Savings ($/year) Reduced costs from fewer mistakes, returns, or corrections

Other Annual Savings ($/year) Throughput gains, compliance savings, reduced overtime, etc.

Analysis Period (years) Typical automation projects are evaluated over 3–5 years

Discount Rate / Cost of Capital (%) Used for NPV calculation; use your WACC or hurdle rate (commonly 8–12%)

Annual Labor Savings = Hours Saved per Week × 52 × Hourly Labor Rate

Annual Gross Savings = Annual Labor Savings + Error & Rework Savings + Other Annual Savings

Annual Net Savings = Annual Gross Savings − Annual Maintenance & Licensing Cost

Simple Payback Period = Implementation Cost ÷ Annual Net Savings

Simple ROI = [(Annual Net Savings × Years − Implementation Cost) ÷ Implementation Cost] × 100%

Net Present Value (NPV) = −C₀ + Σ [Annual Net Savings ÷ (1 + r)ᵗ] for t = 1 to n

where C₀ = implementation cost, r = discount rate (decimal), n = analysis period in years

Internal Rate of Return (IRR) = rate r* such that NPV = 0; solved numerically via bisection

Labor savings assume 52 working weeks per year with consistent hours saved each week.
Fully loaded labor rate should include salary, benefits, payroll taxes, and overhead — typically 1.25–1.4× base wage (SHRM, 2023).
Implementation cost is treated as a single upfront Year 0 investment; phased rollouts should use NPV with staged cash flows.
Maintenance and licensing costs are assumed constant year-over-year; adjust for known escalation clauses.
A discount rate of 8–12% is typical for corporate automation projects (Damodaran, NYU Stern, 2023).
IRR is computed via bisection over the range −99.9% to 1000%; projects with non-conventional cash flows may have multiple IRRs.
NPV > 0 indicates the project creates value above the cost of capital; IRR > discount rate is the equivalent accept criterion.
This model does not account for tax depreciation (e.g., Section 179 / bonus depreciation), inflation, or productivity ramp-up periods.
