Iron Depreciation

Iron Depreciation

Experience realistic farm equipment resale values with Iron Depreciation, a mod that introduces an alternative vehicle value system based on real agricultural economics data. Using sources like the USDA, Iowa State Extension Service, and Machinery Pete auction records, this mod provides resale values that closely follow real-world depreciation curves.

How It Works

Age Depreciation: Utilizes the declining-balance method, producing a steep early drop that slows over time. This method reflects real trade-in data and the first-year penalty for new equipment.

Hours Depreciation: Independently calculated from age, targeting realistic useful-life hour metrics for each equipment category. Powered machines have steeper hours-penalty curves due to engine wear economics.

Depreciation Rates

• Tractors: 10% annual — ~35% retained at 10 years
• Combine harvesters: 13% annual — ~25% retained at 10 years
• Self-propelled sprayers: 12% annual — ~28% retained at 10 years
• Balers: 11% annual — ~31% retained at 10 years
• Tillage tools: 8% annual — ~43% retained at 10 years
• Grain and crop trailers: 7% annual — ~48% retained at 10 years
• Forestry machines: 12% annual — ~28% retained at 10 years
• Cars and utility vehicles: 12% annual — ~28% retained at 10 years
• Trains: 7% annual — ~48% retained at 10 years
• Pallets and consumables: no depreciation applied

Repaint Costs

Repaint costs are adjusted to match real-world professional paint work, capped at 4% of vehicle price at maximum wear. This mod only replaces the repaint price formula, ensuring compatibility with other repair mods.

Vehicle Coverage

All 120+ official FS25 vehicle types are mapped to their correct depreciation group. Unrecognized mod vehicles default to a generic implement rate.

Minimum Sell Price

No vehicle can sell for less than 5% of its new price, ensuring value for scrap metal and parts.

Technical Notes

This mod replaces the base game sell price and repaint formulas, avoiding unexpectedly low sell prices and calibrating repaint costs to professional rates.
