How do you calculate complaint handling cost?

Multiply complaints received by the average cost per investigation and the completion rate to get variable cost, then add fixed system cost. With 15 complaints at $1,200 each, 80% completion, plus $3,000 fixed, total cost is $17,400.

What is a good cost per complaint for a medical device company?

All-in cost per complaint commonly lands between $400 and $1,500 depending on device risk class and how much investigation each complaint demands. The default scenario here yields $1,160 all-in, which is on the higher end and typical of class II/III devices with formal failure analysis.

Why does completion rate affect the cost?

Completion rate scales how much investigation work is actually performed in the period. At 80%, only 12 of 15 complaints are fully investigated within the window, so variable cost is $14,400 rather than the full $18,000.

What is included in fixed complaint system cost?

It covers eQMS license fees, complaint database maintenance, trending and reporting tooling, and baseline staff time that exists regardless of complaint volume. In the example this is $3,000.

Does this include MDR or vigilance reporting cost?

Only if you fold MDR decision-making and report filing into your average cost per investigation. By default the calculator treats those as part of investigation cost, so raise the per-complaint figure if reportable events are frequent.

How can I reduce complaint handling cost without cutting quality?

Standardize investigation depth by complaint category, automate intake and trending, and resolve recurring root causes through CAPA so complaint volume drops at the source rather than paying to investigate the same failure repeatedly.

MedTech Manufacturing calculator

Complaint Handling Cost Calculator

Complaint Handling Cost quantifies what your post-market complaint process actually costs to run under 21 CFR 820.198 and ISO 13485. Quality and regulatory affairs leaders use it to budget the complaint-handling unit, justify automation of the complaint file, and benchmark cost-per-complaint against complaint volume. For medical device manufacturers, complaints feed MDR/vigilance decisions, so the investigation work is non-negotiable — but the cost is highly visible to finance. Knowing your all-in cost per complaint tells you whether your QMS is efficient or quietly bleeding labor.

What this calculator does

Estimate complaint handling cost from complaint volume, per-complaint investigation cost, closure rate, and fixed system infrastructure.
Use this when budgeting post-market quality resources, justifying complaint management system upgrades, or forecasting quality headcount based on complaint volume trends.
It computes the total annual or periodic cost of running your complaint-handling process by combining variable investigation labor with fixed system overhead.

Formula used

Variable complaint handling cost = complaints received × cost per investigation × completion rate
Total complaint handling cost = variable cost + fixed complaint system cost

Inputs explained

Complaints received per period:
Average cost per complaint investigation:
Investigation completion rate:
Fixed complaint system cost:

How to use the result

Use it when budgeting your complaint-handling unit, building a business case for eQMS complaint automation, or modeling cost impact of a rising complaint trend.
It treats every complaint at the same average investigation cost, so a few high-acuity investigations (those triggering MDRs, CAPAs, or health hazard evaluations) can cost far more than the average implies.

Current U.S. benchmarks

U.S. manufacturing runs at 75.6% of capacity with new factory orders at $657B per month (Federal Reserve and Census, May 2026).
The U.S. has 8,825 medical equipment and supplies establishments employing about 308,388 workers (Census County Business Patterns, 2023).
