Contractors asking "how much does an answering service cost?" get answers ranging from $39/month to $5,000/month depending on which vendor's page they land on. The truth is the price depends on three things: the pricing model (per-minute, per-call, per-month flat), the call volume, and the call duration. The same shop can pay $150/month or $3,500/month for what looks like the same service.
This post breaks down the real pricing math for contractor answering services in 2026, with worked examples for a 300-call month and a 450-call surge week.
The three pricing models
1. Per-month flat with included calls and published overage. Common in AI answering services. Plans like $49/mo (100 calls), $149/mo (400 calls), $349/mo (1,000 calls), with overage at ~$0.99/call. Best for: predictable forecasting at any scale.
2. Per-minute pricing. Common in live receptionist services. Base monthly fee ($235-$325) + per-minute overage ($1.85-$2.00/min). Best for: low call volume with short calls; brand-experience differentiation.
3. Per-call pricing on live services. Less common but used by some vendors. Base monthly fee + per-call overage ($11.50/call typical). Best for: shops with very long average call durations where per-minute would exceed per-call.
Real cost math at 300 calls/month, 4.5 min avg
This is a representative trades shop call volume.
| Service | Calculation | Estimated monthly cost |
|---|---|---|
| OnCrew ($149 plan) | Within 400 included | $149 |
| OnCrew ($49 plan, exceeds limit) | $49 + (200 × $0.99) | $247 |
| Goodcall | $79 base + variable overage | ~$80-$200 |
| Rosie | $49 base + minimal overage | ~$50-$100 |
| Smith.ai live tier | $300 + (270 × $11.50) | $3,405 |
| Smith.ai AI tier | Confirm current pricing | Variable |
| Ruby per-minute | $235 + (300 × 4.5 × $1.85) | $2,733 |
| Nexa per-minute | $239 + (300 × 4.5 × $1.85) | $2,737 |
| AnswerConnect per-minute | $325 + (300 × 4.5 × $1.85) | $2,823 |
| PATLive per-minute | $39 + (300 × 5 × $2) | $3,039 |
The bucket-level reality: AI services run $50-$350/month at this volume. Live services run $2,500-$3,500/month. The 10x difference is the category-level price reality.
Real cost math at 450-call surge month
Same shop, surge week added (heat wave / freeze night / hail event):
| Service | Surge cost | Delta from normal |
|---|---|---|
| OnCrew ($149 plan + 50 overage) | $149 + (50 × $0.99) = $198.50 | +$49.50 |
| Goodcall + surge | ~$120-$250 | +$40-$50 |
| Smith.ai live | $300 + (420 × $11.50) = $5,130 | +$1,725 |
| Ruby per-minute | $235 + (450 × 4.5 × $1.85) = $3,981 | +$1,248 |
| Nexa per-minute | $239 + (450 × 4.5 × $1.85) = $3,985 | +$1,248 |
Surge weeks are where the categories diverge most. The $1,200-$1,700 differential on a single bad week of weather is the real price of per-minute scaling.
The question that decides which model fits
One question, asked honestly:
Is the value of a polished human voice on every call worth $2,000-$3,000/month more than configured AI intake on every call?
The answer for high-touch residential brand businesses is yes. The answer for emergency-call-mix trades shops with after-hours surge exposure is usually no.
There is no wrong answer. The wrong choice is picking the wrong bucket for your actual call mix.
Hidden cost factors
Beyond the published pricing, these matter:
Setup fees. Most AI services have no setup fee. Some live services charge $100-$500 for onboarding. Ask.
Minimum monthly commitments. Confirm whether you can scale down a tier mid-contract.
Per-minute rounding. Some live services round up to the nearest minute on every call; some round up to the nearest 6 seconds. The rounding rule matters at volume.
Add-on fees. Bilingual handling, after-hours premiums, transfer fees, voicemail-to-text, confirm what's included and what's extra.
Contract length. Month-to-month vs annual vs longer. Annual contracts often have lower published rates with cancellation penalties.
Outbound minutes. If the service does outbound work, confirm whether those minutes count against your inbound bucket or have separate metering.
What "unlimited" usually means
When a flat-rate plan says "unlimited" calls or minutes, read the AUP (acceptable use policy). The fair-use cap is usually defined as something like "150% of average usage in the segment". Above that, the vendor reserves the right to throttle or charge.
The honest pricing is published-overage. "Unlimited" with an unwritten cap is a marketing decision.
How to compare vendors apples-to-apples
Run this calculation for any vendor you're comparing:
- Estimate your normal monthly call count. Look at your last 12 months of inbound; take the median.
- Estimate your peak month call count. Look at your worst month in the last 12 (or extrapolate from seasonal patterns).
- Estimate your average call duration. Pull from your VoIP analytics or a sample of recordings.
- Calculate normal-month cost and peak-month cost for each vendor.
- Add setup fee, minimum commitments, and likely overage from add-ons.
- Divide by normal-month call count to get per-call effective cost.
The vendor with the lowest per-call effective cost is not always the right choice. The vendor whose model matches your call profile and brand priorities is.

FAQs
What's the cheapest credible answering service for a 1-truck contractor?
For very low volume (under 50 calls/month), generic AI like Rosie ($49) or Dialzara ($29) is hard to beat on price. For trade-specific safety branches at low volume, OnCrew's $49 tier (100 calls included) is the lowest cost with contractor-specific intake.
Is unlimited calling worth paying for?
Read the AUP. "Unlimited" usually has a fair-use cap. If your normal volume is well below the cap and your peak is also below, it's predictable. If your peak weeks could brush the cap, you're back to per-call uncertainty.
How much should I budget for an answering service?
For a 1-5 truck contractor doing under 200 calls/month, $50-$200/month for AI. For a 5-15 truck shop doing 200-600 calls/month, $150-$400/month for AI or $2,000-$3,500/month for live. For shops larger than 15 trucks with a brand-experience phone differentiator, live can scale into the $5,000+/month range.
Why is the price difference between AI and live so large?
Live services have human cost per minute. AI services don't. The cost difference is real and structural. Whether it's worth paying depends on what the human delivers that the AI doesn't, empathy, edge-case judgment, premium brand experience.
