3D Printing Cost Calculator
Know your print cost. Set your price with confidence.
USD · Filament or resin by weight · No signup requiredA 3d printing cost calculator exposes the number most makers never work out properly: the true cost of a finished part. Because filament is only one of five cost categories, pricing from spool cost alone quietly loses money on every sale.
Below, you’ll find the full cost formula, the retry maths nobody accounts for, and a free tool that produces a per-part figure instantly.
How Much Does 3D Printing Cost?
There’s no universal answer, since cost depends on your machine, your electricity rate and your time. However, the structure of the calculation is always the same.
Five categories make up every print:
| Cost category | What it covers |
|---|---|
| Material | Filament or resin actually consumed |
| Electricity | Power drawn across the print duration |
| Machine time | Depreciation and maintenance per hour |
| Labor | Hands-on setup, finishing and post-processing |
| Extras | Hardware, consumables, packaging, overhead |
Consequently, a print that “costs $2.50 in filament” frequently costs $9 or more once everything is counted. That gap is exactly why so many small print businesses struggle to turn a profit.
The Material Cost Formula
Start here, because it’s the figure most people already track.
Material cost = Batch grams ÷ Package net grams × Package price
For example, a 100 g print from a $25 spool holding 1,000 g:
- 100 ÷ 1,000 = 0.1 spools used
- 0.1 × $25 = $2.50 in material
Crucially, use your slicer’s total rather than the model weight. Supports, rafts, brims and purge towers all consume filament that never appears in the finished part.
For resin, enter mass in grams rather than millilitres. Since resin densities differ between products, converting via your bottle’s stated density avoids a meaningful error.

Electricity Cost Per Print
Power draw is smaller than most makers assume, though it isn’t zero.
Electricity = Watts ÷ 1,000 × Print hours × Rate per kWh
Taking a 120 W printer running 5 hours at $0.20/kWh:
- 120 ÷ 1,000 = 0.12 kW
- 0.12 × 5 = 0.6 kWh
- 0.6 × $0.20 = $0.12
Twelve cents sounds trivial. Nevertheless, across a print farm running 200 hours weekly, that becomes a real line item.
Use measured average power, not the nameplate rating. Because heated beds cycle rather than run continuously, actual draw typically sits well below peak. A basic plug-in energy meter settles this in one print.
Machine Time: The Cost Everyone Skips
This is the most commonly ignored category, and also the most damaging to ignore.
Your printer wears out. Nozzles clog, belts stretch, hotends fail and eventually the machine is replaced. Charging nothing for machine time means your customers effectively get free equipment.
Machine rate = (Purchase cost − Resale value) ÷ Productive lifetime hours + Maintenance per hour
To illustrate, a $600 printer with $100 resale value over 2,000 productive hours:
- ($600 − $100) ÷ 2,000 = $0.25 per hour
- Add roughly $0.25 per hour for parts and maintenance
- Machine rate ≈ $0.50 per hour
Importantly, keep electricity and labour out of this rate. Otherwise you’ll double-count them elsewhere in the calculation.
Failed Prints: The Retry Allowance
Here’s where amateur and professional costing genuinely diverge. Prints fail, so pricing as though they never do guarantees losses.
The calculator scales your production cost using a conservative model:
Retry-adjusted cost = Base cost ÷ (1 − failure rate ÷ 100)
At different failure rates, that looks like:
| Failure rate | Cost multiplier | $10 base becomes |
|---|---|---|
| 0% | ×1.00 | $10.00 |
| 5% | ×1.05 | $10.53 |
| 10% | ×1.11 | $11.11 |
| 20% | ×1.25 | $12.50 |
| 30% | ×1.43 | $14.29 |
This model assumes a failed attempt consumes a full batch of material and machine time. Admittedly, that’s conservative — some failures happen early. However, for pricing purposes, erring toward caution protects your margin.
Track your actual failure rate over a month rather than guessing. Most well-tuned FDM setups land between 3% and 8%.
Labor: Your Time Has a Price
Unattended print time isn’t labour. Hands-on work is.
Count these:
- Slicing and print preparation
- Bed prep and first-layer monitoring
- Support removal and cleanup
- Sanding, priming or painting
- Resin washing and curing
- Assembly and packaging
Don’t count these:
- Hours the printer runs unattended
- Time spent designing the model, unless billing separately
Twenty minutes at $25/hour adds $8.33 to a batch. On a single small part, labour therefore frequently exceeds material cost by a factor of three.
Batch vs Per-Part Costing
This distinction trips up a lot of people, so it’s worth being precise.
Quantity divides batch cost across finished parts. It does not multiply material or time.
How to use it correctly:
- Slice the full plate with all parts arranged
- Enter the slicer’s total weight for the whole plate
- Enter the total print time for the whole plate
- Set quantity to the number of finished parts
If you add parts to the plate, re-slice and update both figures. Otherwise your per-part cost will be wrong in both directions.
Furthermore, running multiple printers simultaneously requires summed printer-hours, not elapsed wall-clock time. Three machines running four hours each is twelve printer-hours.
Markup vs Margin: They’re Not the Same
Getting this wrong is the most expensive pricing error in small manufacturing.
| Method | Formula | On $10 cost at 30% |
|---|---|---|
| Markup | Cost × (1 + % ÷ 100) | $13.00 |
| Margin | Cost ÷ (1 − % ÷ 100) | $14.29 |
Markup measures profit against cost. Margin measures it against selling price.
Consequently, a “30% markup” delivers only a 23% actual margin. If you need 30% margin to cover business overhead, marking up 30% leaves you short every single time.
Note also that the surplus figure excludes sales tax, shipping and marketplace fees. Etsy, eBay and payment processors typically take 8–15% combined, so factor that in before treating the number as profit.
How to Use the 3D Printing Cost Calculator
Follow these steps for an accurate figure.
1 — Set your batch quantity
Enter finished parts on the plate, not print attempts.
2 — Enter slicer totals
Use total grams and total hours for the entire batch attempt.
3 — Add your material pricing
Enter what you actually paid and the net package weight, excluding spool.
4 — Enter measured power and your real rate
Check your utility bill rather than using a default.
5 — Set your machine hourly rate
Calculate it from your printer’s cost and expected lifetime hours.
6 — Add your failure rate
Base it on tracked history if you have it.
7 — Enter hands-on minutes and your labour rate
Value your time at what it’s genuinely worth.
8 — Choose markup or margin
Pick deliberately, since the two produce meaningfully different prices.
Pricing for a 3D Printing Business
Cost is your floor, not your price. Once you know the floor, several other factors set the ceiling.
- Design time — bill separately, or amortise across expected sales
- Rush orders — a 25–50% premium is standard
- Volume discounts — reduce per-part labour, so pass some savings on
- Market rates — check what comparable sellers charge
- Shipping — quote separately rather than absorbing it
- Platform fees — build 10–15% in if selling through a marketplace
Above all, resist competing purely on price. Since anyone can buy the same printer, undercutting is a race you can’t win. Reliability, finish quality and turnaround are far more defensible.
Frequently Asked Questions
Is the 3D printing cost calculator free?
Yes, entirely free with no sign-up. Moreover, everything runs locally in your browser, and you can copy the summary or save a PDF.
How much does a 3D print cost?
Small parts typically land between $1 and $10 in total cost, while large or labour-intensive prints run considerably higher. Material alone is usually a minority of the true figure.
Does infill affect the cost?
Yes, though indirectly. Infill changes your slicer’s weight and time outputs, so enter those updated numbers rather than applying a separate multiplier.
Can I use this for resin printing?
Absolutely. Enter resin mass in grams with the matching bottle’s net weight, then account for washing, curing and gloves under extras.
What should I charge for 3D printing?
Start from your calculated cost, then apply markup or margin deliberately. Remember to add platform fees and shipping separately.
How do I calculate my machine hourly rate?
Take purchase cost minus resale value, divide by expected productive lifetime hours, then add hourly maintenance. Many hobby printers land near $0.50 per hour.
