Resin Cost Calculator
Per-print cost from resin used, bottle price, electricity and consumables — with a wastage uplift so failed prints don't surprise you. Returns total cost plus effective ₹ per ml and ₹ per gram.
Work out what a resin print really costs — not just the raw resin, but the wastage you never account for, the electricity the printer draws, and the per-print consumables like gloves, paper towels and IPA. The result is an honest total plus an effective cost per millilitre and per gram, which is what you need when pricing commissions or comparing resin brands.

The method behind the numbers
Resin cost starts from the bottle price divided by bottle volume, multiplied by the millilitres used. On top of that sits the wastage uplift — a percentage that captures spillage, failed prints and the resin lost cleaning the vat — because the resin you buy is always more than the resin that ends up in finished parts.
Electricity is the printer's power draw times the print duration, billed at your local rate. Consumables are a flat per-print figure. The effective cost per millilitre divides the grand total by the resin actually used, so it folds the fixed costs back into a single rate you can multiply for quick estimates. Currency is whatever you type — the defaults are in rupees, but the maths is unit-agnostic.

Frequently asked questions
Why include a wastage percentage?
Because almost no one prints with zero loss. Between failed supports, vat cleaning, drips and the film at the bottom you can't recover, 5–15% of a bottle never becomes a part. Ignoring it makes every print look cheaper than it is.
How much electricity does a resin printer use?
Far less than people assume — the LCD and a small heater draw roughly 45–100 W depending on model and size. A four-hour print is well under a quarter of a kilowatt-hour, so electricity is usually the smallest line on the bill.
Can I use this in dollars or euros?
Yes. Enter the bottle price and electricity rate in your own currency; the symbols default to rupees but the calculation only cares about the numbers. The output rate is in the same currency you entered.
What goes in 'consumables per print'?
Nitrile gloves, paper towels, the share of an IPA bottle used for washing, and a small amortised slice of the FEP film. ₹10–25 (or the local equivalent) per print is a realistic hobbyist figure.
