Default 35% — research suggests 30–40% of missed callers don't call back
✓ Here are the three most effective ways to recover missed-call revenue.
Three fixes, in order of impact
Fix 01 — Fastest win
Missed-call text-back
When a call goes unanswered, an automated text fires back within seconds: "Hey, sorry I missed your call — I'm on a job right now. What can I help you with?" This alone recovers 20–30% of missed leads that would otherwise call your competitor. Many CRM and call-tracking platforms include this feature, and some basic versions can be set up free through tools like Google Business Messaging.
Fix 02 — 24/7 coverage
AI receptionist or answering service
A virtual receptionist (AI or live) answers every call, captures the lead, and either books the appointment or takes a message. After-hours calls — which account for roughly 40% of missed revenue for most trade and service businesses — are fully covered. The cost of a good answering service is typically $100–$300/month, which pays for itself with a single recovered job.
Fix 03 — Highest leverage behavior change
Call back within 5 minutes
Speed-to-lead is one of the most studied factors in service business conversion. Calling back a missed caller within 5 minutes converts at up to 10× the rate of a callback one hour later. Most local businesses call back in 2–4 hours, or not at all. A simple habit — check missed calls every time you finish a job — can recover a meaningful slice of lost revenue with zero cost.

Want help setting up a missed-call text-back, AI receptionist, or lead follow-up system for your specific business? Biz Profit Marketing sets these up for local service businesses.

How It Works

Three numbers. One honest dollar figure.

The calculator uses a simple, transparent formula — no black boxes, no scary projections. Just your numbers.

1

Your job value

Enter the average dollar amount of one completed job, appointment, or customer transaction. Use your gut number — it doesn't have to be exact.

2

Missed calls per week

How many inbound calls go unanswered on a typical week? Check your missed-call log in your phone or Google Voice if you're not sure.

3

Booking rate assumption

Not every missed caller would have booked. The slider lets you set how many you think would have — default is 35%, which matches published research on missed-call conversion.

4

Instant result

Monthly and annual lost revenue update live as you type. The formula is: missed/week × 4.33 × booking rate × avg value.

Common Questions

Frequently asked questions

The calculator gives you an estimate based on your inputs and the booking rate assumption. It's designed to be honest and transparent — that's why the booking rate is a visible slider with a clear default, not a hidden multiplier. The result is a rough but useful order-of-magnitude figure for how much revenue your missed calls represent. Most businesses find the actual number is higher than they expected.
The default is 35%. Research on missed business calls suggests 30–40% of callers who don't reach you on the first try don't call back. Use a lower rate (15–25%) if you're in a highly competitive market where callers have many options. Use a higher rate (50–60%) if you're in a high-demand niche with few local competitors or offer a specialized service where customers tend to be persistent.
Check your phone's missed-call log and average it over a couple of weeks. If you use Google Voice, a business phone line, or a VOIP service, it likely shows missed-call counts in the dashboard. If you're not sure, start with a conservative guess — even 5 missed calls per week at a $300 average job value adds up to over $28,000/year at the default booking rate.
No. All calculation happens locally in your browser — no data is sent anywhere until you enter your email. When you unlock the fixes, your business type and revenue numbers are attached to your lead record so the follow-up is relevant to your situation.
Yes — select "Other local service" from the business type dropdown. The formula works for any business where inbound phone calls represent booking or order opportunities. For restaurants, you might use average reservation or order value as your "customer value."
