How to Use the Gunpla Painting Cost Calculator
Painting cost varies a lot by kit grade and how many colors you use. HG and RG kits have smaller surface area, so one bottle per color is usually enough, while MG needs about 1.5x more paint and PG needs about 2x more. Enter your kit's grade, the number of colors you'll use, and the price per bottle to get the bottle count and paint cost, then add extras like primer and topcoat for the full material total.
Paint Usage Multiplier by Grade
| Grade | Paint Multiplier | Notes |
|---|---|---|
| HG | ×1.0 | Small surface area, beginner-friendly |
| RG | ×1.1 | More detail, slightly more paint |
| MG | ×1.5 | Larger surface area |
| PG | ×2.0 | Very large area, most detail |
Frequently Asked Questions
Why does paint amount differ by grade?
PG and MG kits have larger surface area and more detail, so they need more paint per color than HG or RG kits.
Should I include primer and topcoat costs?
Yes — primer improves paint adhesion and topcoat protects the finish. Add them in the extras field for an accurate total.
