Resin Price Estimator — How to Estimate Epoxy Resin Cost for Any Project
Getting your epoxy resin budget right before you buy prevents both running short mid-pour and wasting expensive product. This guide walks through the exact method to estimate resin cost for any surface, mould, or river table — in any currency.
Start by calculating exactly how much resin you need. Then multiply by your supplier's price per litre or gallon to get your total material cost.
Calculate Resin Volume →The 4-Step Cost Estimation Method
-
Calculate the volume of resin needed
Use the formula: Length × Width × Depth = Volume. For metric, work in centimetres and you'll get cm³ (millilitres). Divide by 1000 to get litres. For imperial, work in inches and divide by 231 to get US gallons. -
Add a waste factor
Multiply the raw volume by 1.10–1.20 depending on project complexity. Use 1.10 for simple flat pours, 1.15 for typical projects, and 1.20 for complex shapes, moulds with detail, or first-time pours. -
Find your price per unit
Check your supplier's price per litre (UK/EU) or per gallon (US). If comparing across regions, convert: 1 US gallon = 3.785 litres. -
Multiply and add consumables
Total resin cost = (litres with waste) × price per litre. Then add an estimate for consumables (gloves, mixing cups, tape, release wax) — typically £10–£30 / €10–€35 / $15–$40 per project.

Hidden Costs to Include in Your Budget
| Item | Typical Cost | Notes |
|---|---|---|
| Nitrile gloves (box of 100) | £8–£15 / €10–€18 / $10–$20 | Use two pairs per session minimum |
| Mixing cups (pack of 20) | £5–£12 / €6–€14 | Graduated cups reduce measuring error |
| Mixing sticks / silicone spatulas | £5–£20 / €6–€24 | Silicone reusable sticks pay off at scale |
| Foam rollers (for seal coats) | £4–£8 / €5–€10 | 3-inch rollers for tabletops |
| Mould release wax or spray | £8–£18 / €10–€22 | Essential for moulds; one can lasts many pours |
| Masking tape / packing tape | £3–£8 / €4–€10 | For forming edge dams |
| Propane torch / heat gun | £15–£40 / €18–€50 (one-off) | For popping surface bubbles |
| Dust cover / tent | £10–£30 / €12–€35 | For long cure times in dusty environments |

Frequently Asked Questions
Multiply your surface area by the depth per coat, add 15% for waste, then multiply by your epoxy's price per litre or gallon. Add consumables (gloves, mixing cups, tape) and any labour cost for the full project estimate.
1 litre of epoxy at a 3 mm coat thickness covers approximately 0.33 m² (3.6 sq ft). At 1.5 mm (thin seal coat), 1 litre covers roughly 0.65 m² (7 sq ft).
Add 10–15% for waste on most projects. Use 20% for complex shapes, detailed moulds, or first-time pours. Waste includes mixing cup residue, spillage, and small batches that can't be fully used.
UK and EU suppliers price epoxy per litre. US suppliers typically price per gallon (1 US gallon = 3.785 litres). When comparing prices, always convert to the same unit before comparing.
