What You'll Learn:
Cost Per Contact: The Real Numbers
Cost per contact (CPC) is the most important metric when evaluating support channels. It includes agent wages, benefits, technology costs, and overhead—divided by the number of contacts handled. Here's how phone and chat compare in 2025.
Phone Support Economics
Phone support remains the most expensive channel because agents handle one call at a time. Average handle time (AHT) for phone typically runs 6-12 minutes depending on issue complexity.
| Component | Cost Driver | Typical Range |
|---|---|---|
| Agent Wages | $15-22/hour (US) | Largest cost factor |
| Technology | Phone system, recording, IVR | $20-40/agent/month |
| Overhead | Space, equipment, management | 20-30% of wage cost |
| Training | Initial + ongoing | $500-1,000/agent |
Cost per phone contact calculation: If your agent makes $18/hour ($0.30/minute) and average handle time is 8 minutes, your direct labor cost is $2.40. Add technology ($0.50), overhead ($0.60), and quality assurance ($0.30) for a total cost per contact of $3.80-4.50.
According to Gartner, the average cost per phone contact in 2024 was $4.00-5.50, with complex B2B contacts reaching $8-12.
Chat Support Economics
Chat's efficiency comes from concurrency—agents handle 2-4 chats simultaneously depending on complexity and typing speed. This dramatically improves cost efficiency.
| Component | Cost Driver | Typical Range |
|---|---|---|
| Agent Wages | $14-20/hour (US) | Slightly lower than phone |
| Technology | Chat platform, routing, AI | $30-60/agent/month |
| Overhead | Space, equipment, management | 20-30% of wage cost |
| Training | Initial + ongoing | $400-800/agent |
Cost per chat contact calculation: Same $18/hour agent handling 3 concurrent chats with 6-minute average handle time. Labor cost per chat: $1.80. Add technology ($0.60), overhead ($0.45), and QA ($0.20) for a total cost per contact of $1.20-1.80.
Industry benchmarks show chat costs 60-70% less than phone support. For high-volume operations, this difference compounds quickly—10,000 monthly contacts via chat costs $12,000-18,000 vs $40,000-55,000 via phone.
Hidden Cost Factors
Both channels have costs beyond the obvious:
Phone-specific costs: Higher turnover (stressful, monotonous), toll-free number fees, call recording storage, compliance requirements (depending on industry).
Chat-specific costs: Platform licensing, AI/chatbot integration, typing proficiency requirements, quality issues from agent multitasking.
The right choice depends on your contact volume, issue complexity, and customer preferences. Let's look at satisfaction and resolution next.
CSAT & First-Contact Resolution: Which Channel Performs Better?
Cost matters, but customer satisfaction (CSAT) and first-contact resolution (FCR) determine whether customers come back and refer others. Here's how phone and chat compare.
Customer Satisfaction Benchmarks
Phone support consistently scores higher in CSAT surveys, but the gap is narrowing as chat technology improves.
| Channel | Average CSAT | Top Quartile CSAT | Key Satisfaction Drivers |
|---|---|---|---|
| Phone | 78-82% | 88-92% | Personal touch, immediate clarification, complex issue handling |
| Live Chat | 73-77% | 85-89% | Speed, multitasking ability, transcript record |
| 68-72% | 80-84% | Thoughtful responses, documentation |
According to Forrester, phone remains the preferred channel for complex issues (68% preference), while chat is preferred for quick questions (61% preference).
Why phone scores higher: Voice communication allows emotional connection, tone detection, and real-time clarification. Customers with frustrating problems want empathy and immediate answers—phone delivers both.
Why chat is catching up: Younger customers (under 35) prefer text-based communication. Modern chat platforms with AI assistance, quick responses, and skilled agents can match phone satisfaction for many issue types.
First-Contact Resolution Comparison
FCR measures whether issues are resolved in the first interaction without follow-up. Higher FCR drives customer satisfaction and reduces operational costs.
| Channel | Average FCR | Best-in-Class FCR | Common FCR Killers |
|---|---|---|---|
| Phone | 70-75% | 82-88% | Transfers, holds, unclear answers, system limitations |
| Live Chat | 65-70% | 78-84% | Agent multitasking errors, chat abandonment, unclear typing |
| 55-60% | 70-76% | Delayed responses, back-and-forth clarification loops |
Phone's FCR advantage comes from synchronous communication—agents can ask clarifying questions immediately and walk customers through complex steps. Chat's asynchronous nature (typing delays, multitasking) creates more opportunities for miscommunication.
Pro Tip: Track FCR by issue type, not just overall. Some issues (password resets, order status) have 90%+ FCR on chat. Others (technical troubleshooting, disputes) need phone's synchronous flow.

When Phone Support Wins
Phone isn't dead—it's just expensive. For certain situations, phone support delivers better outcomes that justify the higher cost.
Complex Technical Issues
When customers need to troubleshoot multi-step problems, phone wins. Screensharing plus voice guidance resolves issues 40% faster than chat alone.
Examples: Software installation, account setup, integration troubleshooting, payment failures requiring verification.
High-Emotion Situations
Angry or frustrated customers need empathy and immediate acknowledgment. Voice tone conveys concern better than text. Phone de-escalates 60-70% of upset customers in the first interaction.
Examples: Order delays ruining gifts, damaged high-value items, service outages affecting business, billing disputes.
Elderly or Less Tech-Savvy Customers
Demographics matter. Customers over 55 prefer phone 3:1 over digital channels. They're more comfortable speaking than typing and may struggle with chat interfaces.
If your customer base skews older (B2B services, healthcare, financial services), phone should be your primary channel.
High-Value Transactions
When average order value exceeds $500 or lifetime value is high, phone support's premium cost is justified. Personal service drives loyalty and prevents churn.
Examples: Enterprise sales support, custom orders, VIP customer service, renewal negotiations.
Legal or Compliance-Sensitive Issues
Some industries require verbal consent, identity verification, or recorded conversations. Phone is often mandatory for: fraud disputes, medical advice, financial transactions, account closures.
Check your regulatory requirements—chat transcripts may not satisfy compliance needs in regulated industries.
When Chat Fails
If a customer has already tried chat and didn't get resolution, escalate to phone. Forcing them to repeat information in the same channel breeds frustration.
When Chat Support Wins
Chat's efficiency makes it ideal for high-volume, low-complexity scenarios. Here's when to route customers to chat instead of phone.
Quick Factual Questions
When customers need simple information fast, chat dominates. Average chat handle time for tier-1 questions: 2-4 minutes vs 6-8 minutes on phone.
Examples: Order status, tracking numbers, return policies, store hours, product availability, password resets.
Multitasking Customers
Younger customers (18-34) prefer chat because they can continue working, shopping, or browsing while getting support. Phone requires their full attention.
According to Zendesk, 64% of customers prefer messaging channels because they can multitask during support interactions.
After-Hours or Overflow Support
Chat scales more cost-effectively than phone for extended hours. You can route after-hours chat to BPO providers or AI chatbots more easily than phone calls.
Asynchronous chat (customers can wait for responses) works better after hours than phone, where customers expect immediate pickup.
High-Volume Repetitive Issues
When you're handling hundreds of similar inquiries (product launches, shipping delays, promotions), chat agents with macros can respond 3-4x faster than phone agents reading scripts.
Chat also enables AI/chatbot deflection for tier-1 inquiries, reducing human agent load by 20-40%.
Read more: See our AI chatbot deployment guide for deflection strategies.
Customers Who Need Documentation
Chat automatically creates transcripts customers can reference later. This is valuable for: step-by-step instructions, policy confirmations, warranty terms, troubleshooting guides.
Phone calls require note-taking or customers asking you to email instructions separately.
International Customers
Chat works better across time zones and language barriers. Text translation tools help agents support multiple languages. Accents and pronunciation issues that complicate phone support disappear.
Cost-Sensitive Operations
If your margins are thin and contact volume is high, chat's 60-70% cost advantage becomes critical. A store handling 5,000 monthly contacts saves $10,000-15,000/month by routing 70% to chat vs phone.
Building a Hybrid Routing Strategy
The best support operations don't force customers into one channel—they route intelligently based on issue type, customer preference, and agent availability. Here's how to build a hybrid model that balances cost and satisfaction.
Start with Customer Preference
Always offer both channels and let customers choose initially. Track which issues customers select each channel for—this reveals natural routing patterns.
Survey data shows: 40% of customers prefer phone, 35% prefer chat, 25% prefer email or self-service. But preferences vary by issue complexity.
Route by Issue Complexity
Use your help desk tagging to categorize issue complexity. Route automatically based on historical resolution data.
| Complexity | Recommended Channel | Example Issues | FCR Expectation |
|---|---|---|---|
| Tier 1 (Simple) | Chat or Self-Service | Order status, tracking, return policy, availability | 85%+ |
| Tier 2 (Moderate) | Chat with Phone Escalation | Order changes, basic troubleshooting, refund requests | 70-75% |
| Tier 3 (Complex) | Phone Primary | Technical support, disputes, custom orders, high-value issues | 65-70% |
| Tier 4 (Critical) | Phone Only | Fraud, legal, enterprise support, executive escalations | 80%+ (may require multiple calls) |
Enable Seamless Channel Switching
Don't trap customers in the wrong channel. If a chat issue becomes complex, offer immediate phone escalation with context transfer—no repeating information.
Modern platforms (Zendesk, Intercom, Gorgias) support warm handoffs: agent views the chat transcript while speaking to the customer on phone.
Time-Based Routing
Route channels by time of day and agent availability. During peak hours when phone queues are long, promote chat more heavily on your website.
After hours or during holidays, route phone calls to voicemail with "chat is available now" messaging, or use IVR to offer callback scheduling.
Skill-Based Routing
Some agents excel at phone empathy and de-escalation. Others type faster and manage chat concurrency better. Match agents to their strength channels when possible.
Track performance by channel: handle time, CSAT, FCR, and quality scores. Optimize assignments based on data, not assumptions.
Cost-Based Routing (With Caution)
You can route low-value interactions to chat and high-value to phone, but be careful. A $30 order customer today might be a $3,000 customer next year.
Better approach: Route by issue urgency and complexity first, then optimize channel mix to hit cost targets without sacrificing satisfaction.
Hybrid Staffing Model
Train agents on both channels so they can flex between phone and chat based on queue depth. During slow periods, phone agents can take chats. During spikes, chat agents can take overflow calls.
Typical ratio: 60% phone-only specialists, 30% hybrid agents (phone + chat), 10% chat-only specialists. Adjust based on your contact mix.

Implementation Guide: Building Your Channel Strategy
Here's a step-by-step plan to implement phone vs chat routing based on the frameworks above.
Step 1: Audit Current Channel Performance
Pull 90 days of data by channel: contact volume, handle time, CSAT, FCR, and cost per contact. Break down by issue type and customer segment.
Calculate your current cost structure: What percentage of contacts go to phone vs chat? What's the weighted average cost per contact?
Identify inefficiencies: Are complex issues going to chat and failing? Are simple questions burning expensive phone time?
Step 2: Define Your Target Channel Mix
Based on issue complexity distribution, set targets. Example target mix for ecommerce:
- 40% Chat (tier-1 and tier-2 issues)
- 25% Phone (tier-3 and tier-4 issues)
- 20% Self-Service (tier-1 deflection via AI/FAQ)
- 15% Email (non-urgent, detailed inquiries)
Your mix depends on product complexity, customer demographics, and margin structure. B2B SaaS might be 50% phone, 30% email, 20% chat.
Step 3: Configure Routing Rules
Work with your platform provider to set up intelligent routing. Most modern systems support:
Tag-based routing: "Technical_Issue" → Phone queue; "Order_Status" → Chat queue
IVR logic: "Press 1 for order status (chat), Press 2 for technical support (phone)"
Website behavior: Customer viewing FAQ → promote chat widget; viewing contact page → show phone prominently
Queue-based overflow: If phone wait exceeds 10 minutes → offer callback or chat alternative
Step 4: Train Agents on Escalation Protocols
Agents need clear guidance on when to escalate between channels. Create decision trees:
Chat → Phone escalation triggers: Customer frustrated after 2+ exchanges, issue requires screenshare, identity verification needed, high-value customer, legal/compliance issue.
Phone → Chat handoff: Customer needs written instructions, policy documentation, lengthy tracking info better sent via chat.
Step 5: Set Channel-Specific SLAs
Different channels need different targets based on customer expectations and operational costs.
| Channel | First Reply Target | Resolution Target | Occupancy Target |
|---|---|---|---|
| Phone | Under 3 minutes | Same call or 24 hours | 70-75% |
| Chat | Under 2 minutes | Same session or 24 hours | 75-80% (with concurrency) |
| Under 12 hours | 24-48 hours | 80-85% |
Step 6: Monitor and Optimize
Track weekly: channel mix %, cost per contact by channel, CSAT by channel, FCR by channel and issue type, and agent utilization.
Run A/B tests on routing rules. Does promoting chat first reduce costs without hurting CSAT? Test for 2-4 weeks and measure.
Quarterly reviews: Adjust channel mix based on seasonal patterns, product changes, and customer feedback.
Common Implementation Mistakes
Hiding phone numbers: Forcing customers into chat alienates older demographics and complex issues. Always offer both.
Undertrained chat agents: Chat requires strong writing skills, multitasking ability, and product knowledge. Hire and train accordingly.
No escalation paths: When chat fails, customers should escalate immediately, not wait in a new phone queue from scratch.
Ignoring customer feedback: Survey customers after channel switches. If they hate it, your routing logic is wrong.

Frequently Asked Questions
How much does phone support really cost compared to chat?
Phone support costs $4-5.50 per contact on average, while chat costs $1.20-1.80 per contact—about 60-70% less. The difference comes from chat agents handling 2-4 conversations simultaneously while phone agents handle one call at a time. For 10,000 monthly contacts, phone costs $40,000-55,000 vs chat at $12,000-18,000.
Which channel has better customer satisfaction?
Phone support averages 78-82% CSAT vs chat at 73-77%, but the gap is narrowing. Phone wins for complex issues because voice communication allows empathy and real-time clarification. Chat performs well for quick questions, especially with younger customers who prefer text communication. Top-performing chat operations achieve 85-89% CSAT—nearly matching phone.
What is first-contact resolution and why does it matter?
First-contact resolution (FCR) measures whether issues are resolved in the first interaction without follow-up. Phone averages 70-75% FCR vs chat at 65-70%. Higher FCR improves customer satisfaction and reduces costs—every follow-up contact doubles your cost per issue. Track FCR by issue type, not just overall, to identify routing opportunities.
When should I use phone support over chat?
Use phone for: complex technical issues, high-emotion situations (angry customers), elderly or less tech-savvy customers, high-value transactions, legal/compliance issues, and when chat has already failed. Phone's synchronous communication and empathy delivery justify the higher cost for these scenarios.
When should I use chat support over phone?
Use chat for: quick factual questions (order status, tracking, policies), customers who want to multitask, after-hours support, high-volume repetitive issues, international customers, and cost-sensitive operations. Chat's efficiency (2-4 concurrent conversations per agent) makes it ideal for tier-1 support at scale.
How do I build a hybrid phone/chat routing strategy?
Start with customer preference, then route by issue complexity. Use tier-1 (simple) for chat, tier-3+ (complex) for phone. Enable seamless channel switching so customers can escalate from chat to phone without repeating information. Track performance by channel and adjust routing rules based on CSAT, FCR, and cost data.
How many chat conversations can one agent handle simultaneously?
Most agents handle 2-4 chats concurrently depending on complexity and typing speed. Simple tier-1 issues (order status, tracking) support 3-4 concurrent chats. Complex issues requiring research or long responses work better at 2 concurrent chats. New agents should start at 2 and increase as they gain proficiency.
Should I hide my phone number to save costs?
No. Hiding phone numbers alienates customers who prefer or need phone support, especially older demographics and those with complex issues. Instead, promote chat prominently while keeping phone accessible. Use IVR to route simple issues to chat and reserve phone capacity for complex scenarios.
How do I calculate my current cost per contact?
Total all costs (agent wages + benefits + technology + overhead + management) and divide by total contacts handled in a period. For phone: include system costs, toll-free fees, recording. For chat: include platform licensing, AI tools. Track by channel separately to identify optimization opportunities. Use our calculator to model scenarios.
What's a good channel mix for ecommerce?
Typical ecommerce mix: 40% chat (tier-1 and tier-2), 25% phone (tier-3 and tier-4), 20% self-service (AI/FAQ deflection), 15% email. Adjust based on product complexity, customer demographics, and margins. B2B or high-ticket ecommerce skews more phone; consumer goods with simple products skews more chat.
Conclusion
Phone and chat both have a place in modern customer support—the question isn't which to choose, but how to route customers intelligently between them. Phone delivers higher satisfaction and first-contact resolution for complex, emotional, or high-value issues. Chat provides cost-efficient support at scale for quick questions and tech-savvy customers.
The winning strategy is a hybrid model that routes by issue complexity, enables seamless escalation, and matches channels to customer preferences. Stores that force one channel or ignore routing logic waste money on overpriced simple interactions or frustrate customers with inadequate support.
Key Takeaways:
- Phone costs $4-5.50 per contact vs chat at $1.20-1.80—about 60-70% less for chat due to agent concurrency
- Phone wins on CSAT (78-82%) and FCR (70-75%), especially for complex issues, but chat is closing the gap
- Route tier-1 simple issues to chat, tier-3+ complex issues to phone, and enable easy escalation between channels
