How benchmarks work in this tool: Miss rate and close rate are industry averages derived from the sources below. They are not editable because they are research-derived. Average job value is pre-filled from the benchmark but you can override it with your actual number.

Calculation methodology
Revenue loss model
monthly loss =
calls × miss rate
× close rate
× avg job value
Close rate is the estimated percentage of unanswered calls that would have converted to a paying booking if a live person had answered. Derived from industry call tracking data.
Seasonal projection
monthly[i] =
loss × (1 + sin(
(i−2) × π/6
) × 0.22)
The 12-month curve uses a sinusoidal model to reflect typical call volume seasonality. This is a modeled estimate, not historical data from your business.
5-year projection
year[n] =
annual × (1.03)^n
for n = 0 to 4
Assumes 3% year-over-year growth in call volume, consistent with US small business service sector averages (Bureau of Labor Statistics, 2023).
Data governance
How data is stored
All benchmark values live in a single config file separate from the application code. Benchmarks can be updated without redeploying the site. The tool fetches fresh data on every page load.
How staleness is detected
Each benchmark has a verification date. If any benchmark is older than 24 months, the tool automatically flags it with an amber warning in the calculator and on this page.
How benchmarks are updated
Benchmarks are reviewed annually against their primary source. When a source publishes new data, values are updated and the verification date is refreshed.
Source link policy
All source URLs point to the report landing page rather than a specific year's PDF. This ensures links remain valid as reports are updated annually.
Important disclaimer: All figures are industry benchmarks derived from the reports linked in the table above. They represent averages across large datasets and may not reflect your specific market, geography, or staffing model. Unanswered ROI is an estimation tool, not a financial audit. Override the pre-filled job value with your own number for a more accurate calculation.
