What is Cost per resolution?
Cost per resolution is the total service cost divided by the number of customer issues successfully resolved during the measured period.
- Aliases
- Cost per resolution technology, cost per contact

Why is cost per resolution important for service economics?
Cost per resolution connects operating spend with successfully solved customer issues, making it more outcome-focused than cost per contact alone.
- Compares efficiency across channels and workflows.
- Shows whether automation reduces total cost, not just agent time.
- Accounts for repeat contacts caused by incomplete resolution.
- Supports investment decisions using a consistent outcome unit.
How Cost per resolution works
- Choose an eligible set of issues and define what counts as a verified resolution.
- Allocate labor, platform, telephony, vendor, and rework costs to that same population.
- Exclude unresolved contacts from the resolution count while retaining their costs.
- Divide total eligible cost by verified resolutions, then segment by intent, channel, and automation path.
Cost per resolution in action
An AI flow costs less per contact than a human queue, but 18% of its contacts return within three days. After adding repeat-contact cost and using verified resolutions as the denominator, its cost per resolution is higher than the first dashboard suggested.
How Cost per resolution is measured or evaluated
Use a stable definition and representative production data. Review these measures together:
- cost per resolution: eligible total cost divided by verified resolutions
- cost per contact and contacts per resolution
- repeat-contact and rework cost
- incremental savings against a valid baseline
Limitations, risks, and common failure modes
- Using closed contacts instead of resolved issues understates cost.
- Ignoring fixed, vendor, and quality costs makes automation look artificially cheap.
- Different intent complexity makes raw team comparisons unfair.
- Currency, allocation, and observation-window changes can break trends.
Cost per resolution vs. cost per contact
Cost per contact prices each interaction. Cost per resolution accounts for how many interactions and resources were required to complete the underlying issue.
What teams should consider when using or implementing Cost per resolution
- Publish cost inclusions, allocation rules, and resolution evidence.
- Match the cost and resolution populations exactly.
- Use intent-adjusted comparisons and confidence intervals.
- Include follow-up contacts and human recovery work.
- Track quality and customer effort beside cost.
