Route Density and Drive Time

Excel Formulas › Landscaping & Lawn Care

All versions

Profit on a mowing route hinges on drive time vs work time. The drive-time ratio — driving over total route hours — shows how much paid time is spent on the road, not the lawn.


Quick formula: drive-time share of the route:
=drive_hours / (drive_hours + work_hours)
Driving over total route hours. 1.5 driving of 7.5 total is 20% — the lower, the denser and more profitable.

The example

1.5 drive, 6 work hours.

The formula

The formula:

=drive_hours / (drive_hours + work_hours) // drive ÷ total route hours

How it works

How it works:

  1. Total drive time and work time across the day’s stops.
  2. Drive share = drive ÷ (drive + work) — lower is denser.
  3. Stops per hour = stops ÷ total hours — a density proxy.
  4. Tighter routes mean more billable lawns per paid hour — the core of route profitability.

Route density, not lawn price, often decides the margin. Two crews charging the same per lawn earn very differently if one drives 20% of the day and the other 40% — every drive-time hour is paid but unbillable. Clustering accounts by neighborhood (and dropping the geographic outliers) raises stops per hour and shrinks drive share, lifting profit on every lawn without changing a single price.

Revenue per route hour

Profit lens:

=route_revenue / (drive_hours + work_hours)

Pitfalls & errors

Drive is paid. Count it — it’s unbillable but real.

Cluster accounts. Geographic density cuts drive share.

Zero hours. Empty route gives #DIV/0!.

Frequently asked questions

How do I calculate route drive-time share in Excel?
Drive over total route hours: =drive_hours / (drive_hours + work_hours). 1.5 of 7.5 is 20%.
What's a good drive share?
Lower is better — it means denser routes and more billable lawns per paid hour.
How do I improve route density?
Cluster accounts by neighborhood and drop geographic outliers to raise stops per hour.
