Why does utilization matter so much?

Higher utilization spreads fixed costs (capex + integration) across more productive hours. Payback improves quickly if the robot stays busy and reliable.

What is the difference between utilization and uptime?

Utilization is how much of the scheduled time the robot is assigned productive work. Uptime is the fraction of time it is operational vs down for faults or maintenance.

Does this replace a full ROI model?

No. This is a scenario tool for sensitivity. Real ROI also depends on integration, safety constraints, throughput limits, and process redesign.

Robot Payback vs Utilization Simulator

See how payback changes as utilization moves from low to high. Model capex, integration, monthly opex, uptime, shifts, and labor cost. Includes a sensitivity heatmap (utilization × labor cost).

Inputs Scenario model

Robot capex (USD)

Integration (one-time, USD)

Robot opex (USD/month)

Maintenance + service + software + energy (rough monthly estimate).

Uptime (%)

Shifts/day (1–3)

Hours/shift

Base utilization (%)

How busy is the robot when scheduled (assigned productive work).

Fully-loaded labor cost (USD/hour)

Include taxes, benefits, overhead where applicable.

Labor replaced (FTE)

0.8 means you reclaim ~80% of one full-time role.

Workdays per year

Use 250 for business days; 365 for 24/7 ops.

Heatmap labor cost range (min → max, USD/hour)

Payback = (capex + integration) / monthly net benefit. Net benefit = labor value − opex. This ignores financing and tax effects.
