How this Prusa price calculator helps you quote faster
Many makers underprice prints because they only look at filament usage. In real jobs, filament is often just one part of total cost. Electricity, wear on your printer, setup time, post-processing, and failed prints all matter. This calculator combines those pieces so you can create quotes that are both competitive and profitable.
If you run a Prusa MK4, MINI+, or XL, this framework gives you a reliable baseline. You can then tune the numbers based on your own materials, local power rates, and the amount of finishing each part needs.
What the calculator includes
- Filament cost: Based on grams used versus spool cost and spool weight.
- Power cost: Estimated from average wattage and your $/kWh rate.
- Machine hourly cost: A practical way to include maintenance and depreciation.
- Labor: Setup, support removal, sanding, inspection, packing, and communication.
- Failure rate adjustment: Adds a realistic buffer for reprints and downtime.
- Profit margin: Ensures your final quote includes actual profit, not just break-even.
Input guide for better accuracy
1) Filament values
Use your slicer estimate for grams. For spool price, include shipping if that is part of your normal cost. If you buy 750g, 1kg, or 2kg spools, make sure the spool weight matches exactly.
2) Time and power
Print hours should include full machine runtime for that part. Power draw varies by bed temperature, enclosure, and filament type. PLA may be lower than ABS, ASA, or PETG jobs that run hotter for longer periods.
3) Machine and labor costs
Machine hourly cost is where you capture nozzle wear, consumables, occasional replacement parts, and long-term printer value loss. Labor should include every minute you touch the job, not only print start time.
4) Failure rate and margin
A low-risk repeat part might have a 5% failure rate; a large or complex part may need 15% or more. Margin depends on your business model, but many small print services target 20% to 50% depending on demand and turnaround speed.
Example pricing workflow
Let’s say a functional bracket uses 120g of PETG, prints in 6 hours, and needs 20 minutes of cleanup and packing. If material, power, and labor add up to roughly $10.50, then a 12% failure adjustment pushes true cost to about $11.76. Add a 30% target margin and your recommended pre-tax sale price becomes around $15.29.
This is exactly why many makers feel “busy but not profitable.” Without failure and labor costs, the same part might be quoted near $9 to $11, which quietly erodes margins over time.
Common mistakes to avoid
- Charging only by filament grams and ignoring time-heavy jobs.
- Using zero labor cost because “it only takes a few minutes.”
- Ignoring failed print probability, especially on overnight prints.
- Setting one fixed price-per-gram for all part types.
- Forgetting packaging, labeling, and admin overhead for shipped orders.
Tips to improve your Prusa printing margins
- Create separate presets for PLA, PETG, ASA, TPU, and engineering materials.
- Track actual failed print percentage monthly and update the calculator.
- Bundle small parts into one build plate to reduce handling overhead.
- Offer rush pricing for tight deadlines.
- Document your finishing steps so labor estimates stay consistent.
Final thought
A solid price system gives you confidence in every quote. Use this Prusa price calculator as your baseline, then refine it with real production data. Over time, this approach helps you avoid undercharging, protect your schedule, and build a healthier 3D printing business.
