Now imagine converting those "lost" calls into revenue while slashing labor costs. Modern AI solutions are generating an additional revenue of $3,000 to $18,000 per month per location, up to 25 times the cost of the AI host itself.

Most restaurant owners underestimate their true phone costs. In-demand establishments receive between 800 and 1,000 calls per month. (Forbes: How AI Is Transforming Restaurants) For a typical 50-seat bistro, call volumes average 1,200+ monthly. (Hostie AI vs Loman: 2025 Feature, Price & Accuracy Shoot-Out for 50-Seat Restaurants)
Here's what those calls typically break down to:
| Call Type | Percentage | Monthly Volume (1,000 calls) | Revenue Impact |
|---|---|---|---|
| Basic Questions | 60% | 600 | $0 (pure cost) |
| Reservations | 25% | 250 | High value |
| Orders | 10% | 100 | Direct revenue |
| Complaints/Issues | 5% | 50 | Retention critical |
"The phones would ring constantly throughout service," explains one restaurant owner. "We would receive calls for basic questions that can be found on our website." (When You Call a Restaurant)
Every minute your staff spends answering "What time do you close?" is a minute not spent with paying customers. In 2025 wage conditions, this opportunity cost compounds quickly:
Before diving into calculations, collect these key metrics from your restaurant:

Use this formula to determine your monthly phone management expense:
Monthly Phone Cost = (Calls per Month × Average Call Duration × Hourly Wage) ÷ 60
Example Calculation:
But this only captures direct labor. Add these hidden costs:
True Monthly Cost: $1,000 × 1.65 = $1,650
AI hosts don't just cut costs—they generate revenue. Companies like Newo.ai, Slang, RestoHost, Hostie, Revmo, and PolyAI are not just managing bookings; they are engaging in natural conversations, handling multiple languages, and showcasing soft skills previously thought to be exclusive to humans. (Forbes: How AI Is Transforming Restaurants)
Revenue generation comes from:
Increased Order Capture:
Enhanced Customer Experience:
Here's the complete ROI calculation framework:
Monthly Savings = Current Phone Costs - AI System Cost
Monthly Revenue Gain = (Captured Orders × AOV) + (Upsells × Average Upsell Value)
Total Monthly Benefit = Monthly Savings + Monthly Revenue Gain
ROI % = (Total Monthly Benefit ÷ AI System Cost) × 100
