Pest Control: Cost per Treatment

Excel Formulas › Pest Control

All versions

A customer pays for a yearly pest plan, but you bill per visit. Divide the annual price by the number of treatments and you instantly see what each service call is really worth.


Quick formula: Annual price divided by the number of visits:
=B2/C2

A $320 quarterly plan with 4 visits works out to $80 per treatment — the number you use to check margins and quote one-off calls.

Functions used (tap for the full reference guide):

The example

Four plan tiers, each with a yearly price and a visit count.

ABCD
1PlanAnnual priceTreatments / yrCost / treatment
2Monthly$54012$45.00
3Bi-monthly$3606$60.00
4Quarterly$3204$80.00
5One-time$1501$150.00

The formula

Drag this down the table:

=B2/C2 // annual price / visits

How it works

It is a single division, but it answers a real pricing question:

  1. B2 is the full price the customer pays for the year.
  2. C2 is how many treatments that plan includes.
  3. Dividing the two gives the revenue earned on each visit — compare it to your cost per stop to see the margin.

Quoting a single visit? Price it at or above your highest per-treatment figure so one-off calls never undercut the plans.

Variations

Add a per-visit chemical cost

Subtract your material cost per stop to see true margin per visit.

=B2/C2-D2

Pitfalls & errors

A blank or zero in the treatments column returns #DIV/0!. Wrap it: =IF(C2=0,"",B2/C2).

Mixing taxable add-ons into the annual price inflates the per-visit number — divide only the recurring service charge.

Frequently asked questions

How do I price a one-time visit?
Set it at or above your highest per-treatment figure (here $150) so single calls stay profitable versus the recurring plans.
What if a plan has variable visit counts?
Use the average visits delivered last year, or divide by the contracted minimum to stay conservative.
