Enter the cost of installation, labor material, excavation, and removal into the calculator to determine the septic cost.

Septic Cost Formula

The following formula is used to calculate the total cost of a septic system.

SC = (I + L + M + E + R)

Variables:

  • SC is the total septic cost ($)
  • I is the cost of installation ($)
  • L is the cost of labor ($)
  • M is the cost of materials ($)
  • E is the cost of excavation ($)
  • R is the cost of removal and disposal of the old system ($)

To calculate the total septic cost, add together the cost of installation, labor, materials, excavation, and removal and disposal of the old system.

What is a Septic Cost?

A septic cost refers to the expenses associated with installing, maintaining, repairing, or replacing a septic system. This can include the initial cost of purchasing and installing the system, regular maintenance costs such as pumping and cleaning, and any necessary repairs or replacements due to damage or system failure. The cost can vary greatly depending on the size and complexity of the system, the location, and local regulations.

How to Calculate Septic Cost?

The following steps outline how to calculate the Septic Cost using the formula: SC = (I + L + M + E + R).


  1. First, determine the cost of installation ($).
  2. Next, determine the cost of labor ($).
  3. Next, determine the cost of materials ($).
  4. Next, determine the cost of excavation ($).
  5. Finally, determine the cost of removal and disposal of the old system ($).
  6. After obtaining the values for each variable, substitute them into the formula SC = (I + L + M + E + R) and calculate the total septic cost ($).

Example Problem:

Use the following variables as an example problem to test your knowledge.

cost of installation ($) = 5000

cost of labor ($) = 2000

cost of materials ($) = 1500

cost of excavation ($) = 1000

cost of removal and disposal of the old system ($) = 800
