How to Use This Calculator
- Enter Your Filament Used (grams): Start by entering your filament used — this is the primary input for the calculation.
- Fill In Additional Details: Complete the remaining fields: filament cost per kg, print time, electricity rate, printer wattage, printer cost, printer lifespan, markup %. Each value refines the calculation for greater accuracy.
- Click Calculate: Hit the Calculate button to run the numbers. Results appear instantly below.
- Review Your Results: Check your total cost, suggested sell price, material cost. Use these figures to inform your next decision or compare against alternative scenarios.
How It Works
The true cost of a 3D print includes more than just filament. This calculator accounts for all major cost factors to give you an accurate per-print cost.
The basic rule:
- Material cost: filament weight (g) × cost per gram from your spool price
- Electricity: printer wattage × print time × your electricity rate
- Depreciation: printer cost spread over its estimated lifespan in print hours
Add your desired markup percentage to set a fair selling price. Most sellers use 100-300% markup depending on complexity and market. Don't forget to factor in design time and post-processing labor.
Tips & Considerations
- Double-check your filament used before calculating — even small input errors can significantly change your results.
- Run the calculator with different values to compare scenarios and find the optimal approach for your situation.
- Pay attention to both total cost and suggested sell price — they work together to give you the full picture.
- Bookmark this page for quick access next time you need to optimize your prints.
- If you're unsure about your markup %, start with a conservative estimate and adjust from there.
Frequently Asked Questions
How much does filament cost per 3D print?
At $25/kg for PLA filament, a typical small print using 30g of material costs about $0.75 in filament. Medium prints (100g) cost about $2.50, and large prints (300g+) can cost $7.50 or more. Specialty filaments like PETG, ABS, or carbon fiber cost more per kg.
How much electricity does a 3D printer use?
Most FDM 3D printers draw 100-300 watts. A typical 200W printer running for 4 hours at $0.12/kWh costs about $0.10 in electricity. Electricity is usually the smallest cost component — material and time are much bigger factors.
How should I price 3D prints to sell?
Calculate your total cost (material + electricity + depreciation + labor) and apply a markup of 100-300%. Simple prints might use 100% markup, while complex or custom designs can command 200-400%. Factor in design time, post-processing (sanding, painting), and shipping costs.
How do I find the filament weight for my print?
Your slicer software (Cura, PrusaSlicer, etc.) estimates filament weight before printing. It's shown in the print summary along with print time and filament length. For more accuracy, weigh the finished print on a kitchen scale.
What is printer depreciation?
Depreciation spreads the cost of your printer across its useful life. If a $300 printer lasts 2,000 print hours, each hour costs $0.15 in depreciation. This accounts for wear, maintenance, and eventual replacement — an often-overlooked cost in pricing.
Does print speed affect cost?
Yes. Faster prints use less electricity and depreciation time but may sacrifice quality. A print that takes 4 hours instead of 8 saves roughly half the electricity and depreciation costs, though material usage stays the same.
