Contacts per Hour
Definition
Contacts per Hour
Contacts per hour (CPH) is the count of live contacts one agent closes in a paid hour. It spans calls, chats, and email. Team leads use it to test staffing, dialer setup, and forecast plans. It reads volume, not the time each contact takes.
CPH sits in the same KPI stack as average handle time (AHT), occupancy, and adherence. Where AHT measures how long one contact runs, CPH measures how many of them finish.
The two move in opposite directions without being mirror images. Idle time, after-call work (ACW), and shrinkage all drag CPH down — none of them lengthen handle time by a second.
Managers read CPH as an early warning on staffing and system health. A steady drop across a team of 40 agents usually points to CRM latency, script bloat, or a shift in call mix, not to lazy agents.
Pair it with first call resolution (FCR) and customer satisfaction (CSAT) so throughput gains never eat quality.
Key takeaways
- CPH counts completed contacts per agent-hour, not per shift or per day.
- The base formula is total handled contacts divided by total logged-in hours.
- Industry medians span 8–18 CPH for outbound telesales and 4–8 CPH for inbound support (ICMI, 2024).
- Read CPH beside AHT, FCR, and CSAT so extra volume never buys a quality drop.
- Auto-dialers, IVR routing, and CRM screen-pops can lift CPH by 20–40% when tuned well.
How it works
Contacts per hour is worked out at agent level, then rolled up to team, campaign, or site. The formula sits at the top of every workforce report: total handled contacts divided by total logged-in hours.
CPH = total handled contacts / total logged-in hours
Some centres divide by productive hours instead, meaning logged-in time minus shrinkage, to isolate the throughput an agent actually controls. Others strip out after-call work so the figure reflects live conversation only.
The choice matters the moment you compare two sites. A Manila team measured on productive hours will always look faster than a US team measured on paid hours, even at identical AHT.
Three levers move the number: call mix (inbound versus outbound, tier-1 versus tier-2), tooling, and coaching maturity. A team with tuned interactive voice response (IVR) routing and a CRM screen-pop can post CPH figures 30% above a comparable team without them.
Workforce management planners also watch occupancy rate alongside CPH. High occupancy with flat CPH is the classic signature of a tooling fault — not an effort problem on the floor.
| Channel / segment | Median CPH | Typical AHT | Notes |
|---|---|---|---|
| Outbound B2C telesales | 12–18 | 3:00–4:30 | Predictive dialer, short pitch |
| Outbound B2B lead-gen | 8–12 | 4:00–6:00 | Manual dial, discovery calls |
| Outbound collections | 9–13 | 4:30–6:00 | Regulated scripts, high retry rate |
| Inbound customer support | 5–8 | 6:00–8:00 | ACW-heavy, ticketing overhead |
| Inbound financial services | 4–6 | 7:00–9:00 | Compliance scripts, verification |
| Live chat (2–3 concurrent) | 10–15 | 8:00–12:00 | Session-based, per-contact varies |

Examples
Published CPH figures cluster by channel and tooling rather than by country. The named cases below come from provider disclosures and campaign reporting, and they show how wide the working band gets once dialers and CRM tooling change.
Concentrix reports that outbound telesales agents on North American retail campaigns average 14–16 CPH on predictive dialers. A 2024 pilot lifted the range to 18 CPH after a CRM consolidation.
Teleperformance’s Manila operations for a US card issuer posted a 22% CPH gain in early 2024 after deploying an AI-assisted screen-pop, with no measurable dip in QA scores.
Foundever, formerly Sitel Group, publishes internal CPH targets in its workforce dashboards. Inbound retail support benchmarks at 6.5 CPH, and a floor of 5.0 flags the campaign for coaching review.
Alorica trains US healthcare campaign agents to a narrower 5–7 CPH band. ISO 18295-1 compliance scripts and HIPAA verification add 45–60 seconds to every contact.
Outbound sales teams read CPH next to a cross-sell matrix, since contact volume says nothing about revenue per contact. A campaign running 16 CPH at 2% conversion loses to one running 11 CPH at 6% — volume is not value.
Genpact, Wipro, and Cognizant tend to publish CPH only inside blended service-level agreement (SLA) reporting, never as a standalone client-facing figure. Enterprise BPOs prefer composite scorecards, so one CPH spike cannot hide a fall in quality assurance or CSAT.
FCR benchmarks are the usual counterweight on those scorecards. When CPH climbs while FCR slides, the extra contacts are repeat callers rather than new work, and the productivity gain is fictional.
Related terms
CPH only makes sense next to the other productivity and quality metrics in the call centre stack. These six terms are the ones that sit beside it on almost every workforce report and client-facing scorecard.
- Average Handle Time (AHT): total time an agent spends on a single contact, including talk, hold, and wrap.
- First Call Resolution: share of contacts fully closed on the first interaction.
- Occupancy Rate: share of logged-in time an agent spends on live contact activity.
- Shrinkage: non-productive paid time such as breaks, training, and meetings.
- Workforce Management: the forecasting and scheduling discipline that turns predicted volume into CPH targets.
- Cross-Sell Matrix: sales-productivity grid that teams pair with CPH on outbound campaigns.
FAQ
Five questions come up on nearly every CPH review, from how it differs from AHT to the way providers report it in contracts. The short answers below match how workforce planners and BPO account teams handle each one.
How is contacts per hour different from AHT?
CPH counts throughput, meaning how many contacts finish inside an hour. AHT measures duration, or how long a single contact takes. They move in opposite directions without being mirror images, because idle time, wrap time, and shrinkage pull them apart.
What is a good contacts per hour for a call centre?
Benchmarks vary by channel: outbound telesales runs 8–18 CPH, inbound customer support 4–8, and inbound financial services 4–6. Anything outside those bands warrants a scripting, tooling, or staffing review.
Can auto-dialers inflate CPH?
Yes, predictive and progressive dialers can lift outbound CPH by 30–50% by stripping out manual dial time. Abandonment rules, set by Ofcom in the UK and the TCPA in the US, cap dialer aggression, so the lift plateaus once the abandonment ceiling is hit.
Should CPH be tied to agent bonuses?
Only with quality guardrails attached, because a pure CPH bonus pays for short, low-value calls. Best practice is a composite of CPH plus CSAT, FCR, or a QA score, reviewed weekly with the team leader.
How do BPO providers report CPH to clients?
Most SLAs quote CPH weekly at campaign level with a monthly rolling average, and ISO 18295-2 recommends that measurement definitions and exclusions sit inside the master services agreement rather than a side annex.
