66.6667 is the example result. Read it using the units and relationship stated below.
3D Printer ROI uses annual return, annual cost.
Making a print estimate reflect the work behind the part
For 3d printer roi, the relationship is ROI (%) = (return − investment cost) ÷ investment cost × 100. The amount depends on the supplied annual return, annual cost, rather than a live market price or a value imported from another record. Filament cost is only one component of a printed part. Machine time, failed jobs, setup, labour and fulfilment can materially change contribution. Compare grams with the usable spool weight, rather than the label price alone.
What the model includes
ROI (%) = (return − investment cost) ÷ investment cost × 100. Use measured print duration where possible and keep machine-hour charges separate from electricity. If the machine rate already includes energy or labour, entering those amounts again double counts them. The model cannot infer a failure rate from a successful test print. A quote still needs the part requirements and production method. Material choice, orientation and finishing affect quality; this estimate does not establish mechanical suitability or guarantee the print will succeed.
Example with the supplied inputs
Annual return: 2000; Annual cost: 1200. Result: 66.6667. The values are illustrative.
Compare one changed input
Annual return changes from 2000 to 2200. The result becomes 83.3333. All other inputs remain fixed.
Calculation rule
ROI (%) = (return − investment cost) ÷ investment cost × 100.
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| Annual return | 2000 | Use the source quantity represented by annual return. Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Annual cost | 1200 | Use annual cost on the currency and period basis shown by the formula. Keep gross amounts, net amounts and unit amounts distinct; the page does not fetch a price or exchange rate. |
Output: 66.6667 is the example result. Read it using the units and relationship stated below. Use the formula to distinguish a cash amount, count, percentage or ratio.
How to use the page
Collect the inputs
Gather Annual return, Annual cost. Use one period and the units shown in the form.
Run the calculation
Enter the values and select the action. The calculation rule above explains how the inputs produce the result.
Compare a scenario
Change Annual return on its own, keeping the other inputs fixed. Read both results before changing another assumption.
Worked example
With the example inputs listed above, the result is 66.6667.
Change Annual return from 2000 to 2200 while keeping every other value fixed. The result becomes 83.3333. This comparison isolates that input; it does not forecast how other variables will respond.
