Use ACTUAL AVERAGE Power (Watts)

Enter the ACTUAL average power consumption of your printer, not the rated (maximum) power. Your printer does NOT consume the rated power continuously. The actual average consumption during a print is typically much lower.

Examples of Rated vs. Actual Average (PLA):

• Bambu P1S: Rated 1100W, actual avg ~100–140W
• Ender 3 Series: Rated 360W, actual avg ~80–120W
• Prusa MK4: Rated 240W, actual avg ~80–100W

How to Find Your Printer's Actual Consumption:

1. Use a Power Consumption Monitoring Plug (Most Accurate)
2. Search Online (e.g., "Actual average power consumption of [Your Printer Model]")
3. Check Manufacturer Specs or reputable forum discussions.

Note: Power consumption is highly variable. It increases significantly with higher print/bed temperatures (e.g., ABS/PC) and during the initial heat-up phase of the print.

Resin MSLA printers draw significantly less power than FDM — no heated bed, no hotend. Examples: Elegoo Mars 4 Ultra ~45W avg, Elegoo Saturn 3 Ultra ~75W avg, Anycubic Photon Mono M5s ~50W avg.

The amortised cost of owning and operating a printer per hour. It covers:

• Depreciation: Printer purchase price spread over its usable lifespan
• Maintenance: Nozzles, beds, belts, lubrication, and other consumables

Example: A printer that cost ₹30,000, lasts ~3 years and runs ~4 hours/day:
30,000 ÷ (3 × 365 × 4) ≈ ₹6.85/hour

This cost is multiplied by print time and added as a direct job cost before overhead and profit are applied.

Leave at 0 if you prefer to cover machine costs through the Overhead % instead.

Resin example: A printer that cost ₹20,000, lasts ~3 years at ~4 hr/day: 20,000 ÷ (3 × 365 × 4) ≈ ₹4.57/hour. Also consider FEP film (~₹500–800 per sheet, replaced every 20–50 prints) as an additional machine cost component.

Printers > Add/Edit Printer > Machine Cost per Hour

The amount charged per hour for the time spent on a job. This rate should be included even if you are the owner performing the work, as your time is valuable. This covers:

• Pre-Print Setup: e.g., slicing, starting the print, loading/unloading spools - 1 to 5 min
• Post-Processing Tasks: e.g., support material removal - 2 to 15 min per part, cleaning, sanding, and packaging

For resin: includes PPE setup (gloves, ventilation check), build plate levelling check — 2–5 min. Post-processing is heavier: support removal, IPA washing (15–30 min), UV curing (5–15 min), sanding and painting if required.

Per-job cost of physical hardware added to a print.

Use this field to include the cost of consumable hardware items that go into a specific job — for example, nuts, bolts, inserts, magnets, or springs embedded in the print.

Supports in-field expressions: You can type a calculation directly into the field, for example:

• 4*0.10 + 2*0.60 → ₹1.60 (4 nuts at ₹0.10 + 2 inserts at ₹0.60)

Hardware cost is a direct job cost — overhead and profit margin are applied on top of it.

Leave blank or at 0 if the job has no embedded hardware.

Calculator > Hardware Cost

Per-job cost of getting the finished print to the customer.

What you pay a courier to deliver the job. Optional - leave blank or at 0 if not applicable.

Unlike Hardware Cost, this is not marked up: Overhead % and Markup % apply only to Material + Labor + Electricity + Machine + Hardware. Shipping Cost is added after that markup, at near cost - so a ₹100 shipping fee adds exactly ₹100 to the price, not ₹100 plus a share of your profit margin.

Remembers your last value: like Labor Time, whatever you type here is remembered and pre-fills the next new job - still fully editable, not locked.

In the price breakdown, it appears (only when non-zero) between Profit and the GST/Final Price lines, since GST - if set - is calculated on the complete total including it.

Calculator > Shipping Cost

Per-job cost of packaging materials for the finished print.

Covers materials like a box, bubble wrap, or tape used to ship the job safely. Optional - leave blank or at 0 if not applicable.

Unlike Hardware Cost, this is not marked up: Overhead % and Markup % apply only to Material + Labor + Electricity + Machine + Hardware. Packaging Cost is added after that markup, at near cost - so a ₹20 packaging cost adds exactly ₹20 to the price, not ₹20 plus a share of your profit margin.

Remembers your last value: like Labor Time, whatever you type here is remembered and pre-fills the next new job - still fully editable, not locked.

In the price breakdown, it appears (only when non-zero) between Profit and the GST/Final Price lines, since GST - if set - is calculated on the complete total including it.

Calculator > Packaging Cost

This percentage is applied to all Direct Costs (Material + Electricity + Labor + Machine + Hardware). It covers non-direct expenses such as: failed prints/reprints, consumables (glue, cleaning agents), and facility costs.

For resin printing, overhead is typically higher (25–35%) due to FEP/nFEP film replacement, IPA wash solution, nitrile gloves, and a higher rate of print failures. When you select a resin printer in the app calculator, a suggested default is shown.

Settings > Overhead

This percentage is the final markup applied to the Subtotal (Direct Costs + Overhead) to determine the final selling price. It represents the net profit generated per job.

Settings > Profit Margin

Applied last, on top of the complete price - Subtotal (Direct Costs + Overhead) + Profit + Shipping + Packaging. It is not applied to the pre-profit Subtotal alone, so Profit Margin % is never itself taxed.

When GST is greater than 0, the breakdown shows both a "Price Before GST" line and a GST-inclusive "Final Price" line. Set it to 0 to hide GST entirely and quote tax-free.

Defaults to 12%: new installs and existing installs updating to this version both start with GST % set to 12, this app's baseline rate - change it in Settings if your rate differs.

Read live, not locked in per job: changing GST % in Settings immediately updates the displayed price of every calculation in your Catalogue, past and future - it is never frozen at the moment a job was saved, unlike Shipping/Packaging cost which are saved per job.

Do math directly in input fields!

All numeric fields support simple calculations. Just type an expression and press Enter or tap outside the field to see the result.

Try these examples:

• 120+30 → 150
• 1.5*2 → 3
• (10+5)*2 → 30
• 100/4 → 25

You can use +, -, *, /, and parentheses () to create complex expressions.

Where it works:

The calculator works in all numeric input fields throughout the app, including:

• Material Weight
• Print Time
• Labor Time
• Material Price and Weight fields
• Other numeric settings

The app calculator only shows printers you've marked as owned (★) — keeping the dropdown manageable when you have a large preset library.

How to mark a printer as owned:
Open the Printers screen and tap the ☆ next to any pre-populated printer. The star fills (★) to confirm it's in your set. Tap again to remove it.

Shortcut: Tap the ⚙ icon next to the printer dropdown in the calculator to jump straight to the Printers screen.

Printers you add yourself are always owned automatically — no need to star them.

If you haven't starred any printer yet, the calculator shows the full library so you're never locked out.

Calculator > Printer

If you own more than one printer, running costs vary by machine (power draw, depreciation, cost per hour). This can cause the same job to produce different quotes depending on which printer you pick, making your pricing inconsistent.

Recommended approach: Always calculate using your most expensive printer as the standard. Jobs actually run on a cheaper printer will yield a higher margin, but you will never underprice. Use the Overhead % to absorb the remaining variance across your fleet.

This keeps your quotes stable and predictable for repeat customers.

Manage and transfer your data with Import & Export

What is this feature?

Import and export features allow you to backup your data, transfer it between devices, or edit your calculations externally in spreadsheet software.

What's included in the export?

• All saved calculations with their details
• Associated materials (names, costs, properties)
• Associated printers (names, models, power consumption)
• Price calculations and job information

Note: Images associated with calculations are NOT included in exports

File Format

The export is a standard CSV file that can be opened in Excel, Google Sheets, or any spreadsheet software.

What happens during import?

• Calculations from the CSV file will be added to your existing calculations
• New materials and printers found in the file will be added to your library
• Existing calculations will not be overwritten or duplicated
• The app will validate the data to ensure it's in the correct format
• Important: Images are not included in imports - you'll need to re-attach them manually

Access this feature

The Import & Export screen can be accessed from:

• Settings screen
• Welcome screen (when no calculations exist)

For resin printing, this field captures the total elapsed time for the job: LCD screen exposure time + UV curing station time.

Both phases consume electricity and count toward machine depreciation.

Wash time is manual labour — include it in Labor Time, not here.

Example: 3h print + 15min cure = enter 3h 15min (or 195 minutes).

Calculator > Print Time

Resin materials work exactly like filament in this app — enter what you paid for the bottle and its weight in grams. Cost per gram is calculated automatically.

Typical bottle sizes: 500g (~420ml) and 1kg (~840ml). Most resins have a density of ~1.1–1.2 g/ml, so a "500ml bottle" weighs ~550–600g — use the actual weight on the label.

Standard resins: ₹800–1,500 per 500g. Specialty (ABS-like, flexible): ₹1,200–2,500.

Materials > Add/Edit Material

Use Hardware Cost to capture per-print resin consumables that aren't covered by overhead:

• IPA wash: ₹15–40 per print (50–100ml @ ₹300–400/litre)
• FEP film amortised: ₹10–25 per print (₹500 sheet ÷ 20–50 prints)
• Nitrile gloves: ₹3–5 per pair

Example expression: 30 + 15 + 4 → ₹49 total consumable cost

Hardware cost is a direct job cost — overhead and profit margin apply on top.
