Septic Cost Calculator

How this calculator works

Each job starts from one published range. Pumping uses national guides' prices by tank size, from $175–$300 for a 750-gallon tank to $345–$600 for a 1,500-gallon tank. If you are not sure of the size, it uses the typical residential pump-out range of $290–$600. Inspections, repairs, drain field work and new conventional systems each use the range the sources support for that job.

The extras you tick are added as separate lines: digging up buried lids, installing risers and cleaning the effluent filter. The after-hours option adds 50% of the low pumping figure and 100% of the high one, because the guide we use publishes that surcharge for pumping only. The total is the sum of the lines. Nothing is weighted or adjusted beyond that.

Permit fees are never in the total. Routine pumping is not a repair under Florida's septic rule, so it does not need a repair permit, but most repairs, drain field work and new systems do, and the fee depends on your county. Our Florida septic pumping cost guide explains every range and the permit fees in more detail, and the county septic permit offices page lists who to contact. When the quotes come in, line them up with the septic quote comparison tool, or see what septic tank pumping and septic repair usually include.

Disclaimer: these are general planning ranges from published national cost guides, plus Florida's state permit fees. They are not a quote or an assessment of your system. Some national figures were last updated before 2026, so local prices may differ. Only a septic company that sees your system can price the job.
