Incoming Inspection Cost Calculator
Cost the actual receiving inspection and distinguish its two unit bases. Enter received and inspected counts, measured labor per checked part, the labor rate and separate lot charges.
What this calculator does
- Calculate incoming inspection expense from the inspected population while showing allocation across the entire received lot.
Formula used
- Inspection labor hours = inspected parts × person-minutes per part ÷ 60
- Labor cost = inspection labor hours × loaded labor rate
- Total cost = labor cost + fixed setup cost + separate testing charges
- Cost per received part = total cost ÷ received parts
- Cost per inspected part = total cost ÷ inspected parts
Inputs explained
- Received Parts: Distinct parts received in the lot being evaluated.
- Inspected Parts: Distinct parts actually checked under the chosen inspection plan.
- Inspection Labor per Checked Part: Measured hands-on time per inspected part, including repeat checks.
- Loaded Inspection Labor Rate: Documented inspection labor rate and overhead scope.
- Fixed Inspection Setup Cost: Lot setup charges excluded from the per-part labor rate.
- Separate Testing Charges: Outside test invoices excluded from labor and setup charges.
How to use the result
- Best suited to receiving cost allocation, supplier inspection workload.
- The inspection plan must be selected and authorized separately. Destructive sample writeoffs are excluded unless already included in entered charges.
Current U.S. benchmarks
- U.S. manufacturing runs at 75.7% of capacity (Federal Reserve, Aug 2026). New factory orders are up 8.5% year over year (Census).
Common questions
- Does this choose an acceptance sample? No. Enter the quantity from your approved plan or actual inspection log; a cost comparison cannot establish a sampling plan.
- Why are there two cost averages? One divides by checked parts, while the other allocates the total expense across all received parts.
- Can every received part be inspected? Yes. Set inspected and received counts equal for complete inspection; the two cost averages then match.
- What if no parts were checked? Inspection labor becomes zero, but lot setup charges can still exist. Cost per inspected part requires a positive checked-part count.
