Simple math, shown in full
Start with the calls you miss in a week and multiply by 4.33, the average number of weeks in a month. Multiply that by the share of missed calls that are real customers, not spam or robocalls, and then by the share of those you'd book if you'd picked up. That gives you the real jobs you miss each month. Multiply by your average job value for the revenue missed per month, and by 12 for the year. With the starting numbers that's 10 × 4.33 × 20% × 50% = about 4.3 jobs, or about $1,949 a month. It counts only the first job, not repeat work or referrals, so the real cost is usually higher.
