Overview Of Costs

Cost ranges for a 120 gallon propane tank include the tank itself, delivery, installation, and ancillary components. Typical cost ranges assume a standard above-ground steel tank with basic mounting and regular maintenance. The total often falls between $2,000 and $5,000 depending on options and local requirements. A per-gallon capacity perspective puts the price around $16–$42 per gallon of capacity, depending on features and service.

What Drives Price

Key cost drivers include tank type (bare steel vs. coated), installation difficulty, and regional regulatory requirements. Regional price differences can be substantial due to labor rates and permit costs. In addition, ongoing maintenance and the need for relocation or expansion later influence total ownership cost.

Ways To Save

Strategic approaches to reduce the 120 gallon tank cost include shopping for a kit that bundles regulator and hoses, scheduling installation in off-peak months, and using a single contractor for delivery and setup to avoid multiple call-out fees. Consider whether a refurbished unit meets local codes and if warranty terms fit long-term use.

Regional Price Differences

Prices vary by region due to labor markets and permitting. In the Northeast, higher permitting and labor costs can raise totals by 10–25% versus the South. Urban areas may incur delivery surcharges, while Rural regions often face longer travel charges and fewer nearby installers. Expect a regional delta of roughly +/- 15% to 25% on base tank prices.

Labor, Hours & Rates

Labor costs depend on crew size and time. A straightforward installation might require 6–12 hours of work for a standard setup, while more complex scenarios (underground lines, multiple tanks) extend to 1–2 days. Fees typically range from $300 to $2,000 for labor, with higher rates in dense markets.
