This calculator shows what missed phone calls cost your business every month. Drag three sliders — how many calls you miss, what a job is worth, how many callers would have booked — and the tab prints itself. Every assumption is yours to change.
warning: the number stings a little ↓Rough guesses are fine — you can be pessimistic and the tab will still surprise you.
On a job, after hours, both hands full — count them all.
What a typical booked job is worth to you.
People calling a business usually want to buy — 30% is a conservative default.
These are your assumptions, not our claims. The defaults are deliberately conservative; the math is shown in full below the calculator.

The math, shown honest
No black box: four multiplications, all of them yours to disagree with.
calls/week × 4.33 — there are about 4.33 weeks in a month. Miss 7 calls a week and that's ~30 a month.
missed calls × booking rate — people don't dial a business to browse. The default assumes just 3 in 10 would have booked; set it lower if you like.
lost jobs × average job value, then × 12 for the year. This is revenue, not profit — but it's revenue that dialed your number.
Most callers who hang up just want an answer, fast. The win-back line assumes an instant text-back saves half the lost jobs — our live demo shows exactly how that conversation goes.
Calculator FAQs
Missed calls per week × 4.33 gives monthly missed calls; multiplied by your booking rate gives lost jobs; multiplied by your average job value gives lost revenue per month, and × 12 per year. Every input is a slider you control — the calculator makes no claims about your business, it just does your multiplication.
Missed call text back automatically sends a text to any caller you don't answer, within seconds — so the conversation continues while you work, and the job gets booked instead of going to the next name on Google. It's included in The Works plan, and you can see a full night of it in action in the demo on our home page.
It's an estimate built entirely from your own inputs — deliberately conservative defaults, no hidden multipliers, and the formula is published right on this page. Use your real numbers from a week of call logs and it gets very accurate, very fast.
