Book 15-min demoHow we got to the numbers
Three assumptions, no magic.
The calculator is honest about what it’s doing. Three inputs in, three outputs out — using one baseline tuned from real HVAC, plumbing, and roofing recovery data.
Missed-call volume
How many calls roll to voicemail in a typical month. Most shops undercount this — every office-hours ring-out counts, not just the ones dispatch noticed.
Average job value
Your average ticket, net of discounts and callbacks. Tune-ups blend up the figure; replacements drag it down. Use what your P&L shows.
55% recovery baseline
A conservative floor measured across real Wrenchmark installs — most shops land a touch higher, some lower. The honest first-pass number, not the optimistic pitch.
