Lab Production Scheduling Calculator

Estimate daily case throughput from technician count, case complexity mix, and working hours.

About this calculator

Cases per Day is set mainly by Number of Technicians, combined with a fixed 80% effective-utilization factor built into this calculator -- the tool assumes 20% of every scheduled hour goes to breaks, case setup, and cleanup regardless of lab size, so raw technician-hours are discounted by that constant fraction before any case gets counted. Avg Case Time and Complex Cases both pull Cases per Day down: complex cases are modeled at 1.8x the bench time of a standard case, so a higher Complex Cases percentage raises the weighted average minutes per case and squeezes fewer cases into the same technician-hours even though staffing never changed. Rush Cases works in the opposite direction here -- this calculator's rush multiplier (0.7x) assumes expedited cases are simpler or partially outsourced, so a workload skewed toward Rush Cases nudges throughput slightly up rather than down, though the effect is small next to technician count and average case time.

Work Days per Month only scales Cases per Day into Cases per Month; it has no effect on Cases per Day itself, since daily capacity and the number of working days in a period are independent quantities. Est. Monthly Revenue applies a flat $150-per-case assumption built into this calculator, not a figure drawn from a published lab fee survey -- real case value varies enormously by restoration type and material, from a single retainer to a full-arch implant case, so treat the revenue estimate as a rough planning number rather than a fee schedule.

How to Use This Calculator
  1. Enter the number of Production Technicians and Working Hours per Day.
  2. Set the Average Case Time (min) based on your lab's standard bench time.
  3. Input the percentage of Complex Cases and Rush Cases in your typical workload.
  4. Enter Work Days per Month for the current scheduling period.
  5. Review Cases per Day, Cases per Month, and Average Turnaround Days to plan staffing and workflow.

Frequently Asked Questions

Why does raising Complex Cases lower Cases per Day?

Complex cases are modeled to take 1.8 times as long as a standard case in this calculator's weighted-average formula, so as Complex Cases rises, the average minutes needed per case rises with it, and fewer cases fit into the same pool of technician-hours each day -- even though nothing about staffing or scheduled hours changed.

Does adding more Rush Cases slow the lab down?

No -- this calculator assumes rush cases actually take less bench time (a 0.7x multiplier) because they are typically simpler or partly outsourced, so a workload skewed toward Rush Cases nudges Cases per Day slightly upward rather than downward, though the effect is modest compared to technician count or average case time.

Does Work Days per Month change how many cases the lab produces daily?

No -- Work Days per Month only multiplies Cases per Day into Cases per Month; it has zero effect on Cases per Day itself, since a lab's daily capacity depends on technicians, hours, and case mix, not on how many working days happen to fall in a given month.

Is the $150 average revenue per case a real dental lab fee?

No -- it is a flat planning assumption built into this calculator so it can show a rough monthly revenue figure alongside case counts. Real case value varies widely by restoration type, material, and region, so treat the dollar figure as illustrative rather than a published fee benchmark.

Why does the calculator discount scheduled hours by 20% instead of counting them in full?

It accounts for breaks, case setup, cleanup, and other non-production time that a real lab day always includes. That 20% factor stays constant regardless of technician count or hours entered, so it scales throughput down uniformly rather than changing which input drives the result.
