AI Phone Assistant ROI Calculator: How Much Are Missed Calls Costing You?

Do The Math On Your Missed Calls

Most business owners know they miss calls. Few know how much it actually costs them. Let's calculate it.

The Formula

Monthly Revenue Lost = Missed Calls × Answer Rate × Conversion Rate × Average Job Value

Example Calculations

Plumber

Missed calls/month: 12

Would have answered: 85% (10 calls)

Conversion rate: 60% (6 jobs)

Average job value: $450

Monthly loss: $2,700

Ringix cost: $297 → ROI: 9x

Dentist

Missed calls/month: 15

Would have answered: 85% (13 calls)

Conversion rate: 50% (6 new patients)

Average first visit: $300 (LTV: $1,200/yr)

Monthly loss: $1,800 (first visit) / $7,200 (annual value)

Ringix cost: $297 → ROI: 6x to 24x

Law Firm

Missed calls/month: 8

Would have answered: 85% (7 calls)

Conversion rate: 30% (2 new clients)

Average case value: $5,000

Monthly loss: $10,000

Ringix cost: $297 → ROI: 33x

Auto Repair

Missed calls/month: 20

Would have answered: 85% (17 calls)

Conversion rate: 50% (8 jobs)

Average repair: $500

Monthly loss: $4,000

Ringix cost: $297 → ROI: 13x

Your Calculation

How many calls do you miss per month? (Check your voicemail count, or estimate)

Multiply by 0.85 (calls that would convert if answered)

Multiply by your conversion rate (usually 30-60%)

Multiply by your average job/sale value

The answer is almost always 10x+ the cost of Ringix.
