Run the numbers.
On your inputs. Not ours.
This is the interactive ROI calculator for the Tennant node. Every input is adjustable: the remediation window, the manual PO volume, the labor cost per PO, the loaded labor rate, the disclosed remediation spend. The calculator compares two paths — Do Nothing vs. Activate — across the same window. The delta is the ROI. Defaults come from public disclosure. Every input can be changed so Tennant can model their own scenario.
Two paths. One window.
Move the sliders.
Do Nothing path: manual PO labor plus disclosed remediation spend across the window. Activate path: layer activation + operation plus residual remediation. The delta is the ROI. Every input is a slider.
Do Nothing
Activate the Layer
Three scenarios. Click to load.
Each preset adjusts the calculator to a different scenario. The Disclosed preset uses only numbers Tennant has stated publicly. The Conservative preset holds the inputs at their most defensible floor. The Aggressive preset models the upper-bound case.
The defensible floor.
Smaller window, lower manual PO volume, lower labor rate. Uses the smallest defensible numbers.
Tennant's own numbers.
Uses only what Tennant has publicly disclosed: $30M impact, $20M+ remediation, ~160 manual POs/day, 18-month horizon.
The upper-bound case.
Longer window, higher manual PO volume, higher labor rate. Uses the largest defensible numbers.
Every number. Explained.
Every formula used in the calculator is shown here in the open. Nothing is computed by a hidden path. Nothing is left to interpretation.
Path A · Formula
Do Nothing Path
Manual PO labor across the window, plus the full disclosed remediation spend allocated proportionally to the window.
(POs/day × labor mins ÷ 60 × rate × 22 days × months) + (remediation × months/18)
Path B · Formula
Activate Path
Layer activation plus monthly operation across the window, plus residual remediation (25% of disclosed — the portion not eliminated by the layer).
$250K + ($35K × months) + (remediation × 25%)
Delta · Formula
Net ROI
The difference between the two paths. Positive delta means activation recovers more than it costs across the selected window.

Where the numbers come from
Every default is sourced to Tennant's public disclosures — earnings calls, SEC filings, investor communications. Every input is adjustable so Tennant can substitute their own operating assumptions.
