What costs should I include in a project estimate?

Include the base kit, any aftermarket detail sets (photo-etch, resin, decals), all paints and thinners, glue, filler, sandpaper, and any new tools you need to buy. Many modellers forget consumables like masking tape and cotton buds.

How much does an average model kit project cost?

A basic 1:72 aircraft kit might cost £15-£30 all-in. A detailed 1:35 armour build with aftermarket can run £80-£150. A large 1:32 aircraft with full detail sets can easily exceed £200. Paints and consumables typically add 30-50% to the kit price.

Should I include tools I already own?

Only include tools you need to purchase specifically for this project. If you already own a full toolkit, leave the tools cost at zero. Some builds require specialist items like rigging tools or specific drill bits.

How can I reduce project costs?

Buy paints in sets rather than individually, use generic brands for primers and clears, scratch-build detail parts instead of buying aftermarket, and look for kit deals at model shows. Sharing paint sets with club members also helps.
