From one print run to a price you can trust.

How this calculation works

Quantity is the number of sellable items from one complete print run. Costs created once per run are divided by this number; per-item costs are added afterward.

How this calculation works

Material cost = (slicer weight + support or purge material) × material buffer × spool price ÷ usable spool weight. Failed-print risk is applied later, so it is not counted twice.

1. Material used in this print runUse the totals for the complete plate, not one item.

Material typeUsed to identify the material; it does not change the formula.Material shown by the slicergTotal filament for the complete plate.Extra material outside the slicergPurging, test lines or waste not included in the slicer total. Enter 0 if none.

2. Spool price and contentsUse the price you paid and the net filament weight printed on the spool.

Spool purchase priceTRYThe amount you actually paid for this spool.Filament in the spoolgNet filament only; do not include the empty spool.Material buffer%Covers small measurement and consumption differences — separate from failed prints.

How this calculation works

Electricity uses average watts × print hours ÷ 1,000 × your kWh price. Machine cost uses print hours × your hourly wear and maintenance cost. Either cost can be marked not applicable or explicitly excluded.

How this calculation works

Setup and active monitoring happen once per print run, then are divided across sellable items. Post-processing and packing time are calculated separately for each item.

LaborRecommended

Your hourly rateTRY/hThe value of one hour of your active work.

How this calculation works

The failed-print rate increases only the costs that must be paid again when a run fails: material, electricity, machine time, setup labor and per-run consumables. Overhead is added per sellable item afterward.

Failed print rateA failed run repeats material, machine, electricity and setup costs.

Consumables

Consumables per runTRYGlue, wipes, gloves or similar supplies used for one complete print run.

Business overheadRecommended

Overhead allocated to this itemTRYThis item's share of common costs such as workshop, software and accounting.

How this calculation works

Packing materials and the carrier charge are costs you pay. The shipping amount paid by the customer is part of the customer total, but it is shown separately from the product price. Platform and payment fees are calculated afterward.

Packing and shipping costs

1. Packing materialsWhat you use to prepare one item for delivery.

Cost per itemTRYBox, filler, tape, label and similar materials.

2. ShippingKeep your carrier expense separate from what the customer pays.

Platform / payment feesRecommended

How this calculation works

Margin measures profit against the customer's total payment. Markup measures profit against your cost. Break-even covers costs and selling fees without adding profit. Tax is not calculated in this prototype.
