How do you calculate total coin door assembly cost?

Multiply quantity by per-door cost by the allocation factor for variable cost, then add fixed setup. For 80 doors at $64 with 100% allocation plus $375 setup, total is $5,120 plus $375, or $5,495.

What is the cost per coin door assembly?

Divide total cost by quantity. Here $5,495 across 80 assemblies is $68.69 per door, which is the $64 variable cost plus the spread of the $375 setup.

How much does fixed setup add per door?

The $375 setup spread over 80 doors adds $4.69 each, lifting the per-door cost from $64 to $68.69. On a 20-door run the same setup would add $18.75 per door.

What does the allocation percentage do?

It scales how much variable cost the order absorbs. At 100% the full $5,120 passes through; at 80% only $4,096 would be allocated, which you might use when shared inventory cost is split across orders.

Why does per-door cost rise on small batches?

Because the fixed $375 setup is spread over fewer units. At 80 doors it adds $4.69 each; at 10 doors it adds $37.50 each, often making small coin-door runs surprisingly expensive per unit.

Should bill validators be in the per-door BOM cost?

Yes, if they ship installed. The $64 per-door figure should include coin mech, validator, lock, harness, and assembly labor; leaving a validator out understates both the $5,495 total and the $68.69 per-door cost.

Gaming & Entertainment Hardware calculator

Coin Door Assembly Cost Calculator

Coin Door Assembly Cost gives a gaming-hardware estimator the fully loaded cost of building a batch of coin doors, the cash-handling subassembly that goes into arcade, redemption, and amusement cabinets. Coin doors carry real BOM weight in coin mechs, bill validators, locks, and wiring, plus assembly labor, and they always carry a fixed setup cost for fixturing and first-article checks. This calculator combines variable per-door cost with that fixed setup and an allocation factor so a quote reflects the true cost of the run. Estimators and buyers use it to price small batches where setup dominates and to see the per-assembly number a customer will scrutinize.

What this calculator does

Estimate the cost of coin door, bill acceptor, card reader, lock, hinge, latch, wiring, and security hardware assemblies for arcade and amusement cabinets.
Use it when arcade builders or entertainment equipment suppliers need to quote coin-door subassemblies, payment door options, access panels, locks, and harnessing for a cabinet run.
It computes total coin door assembly cost as allocated variable cost plus fixed setup, and the resulting cost per assembly.

Formula used

Variable coin door assembly cost = coin door assemblies × coin door bom and labor cost × order allocation for coin door cost
Total coin door assembly cost = variable cost + fixed coin door setup cost

Inputs explained

Coin door assemblies in the order:
Per-door BOM plus labor cost:
Cost allocation applied to this order:
Fixed coin door tooling and setup cost:

How to use the result

Use it when quoting a coin door batch, evaluating a small versus large run, or deciding how much of shared cost to load onto an order.
The allocation factor is a flat multiplier on variable cost; at 100% it passes full cost through, but it does not itself model volume discounts on the BOM, so adjust the per-door cost separately for quantity breaks.

Current U.S. benchmarks

Global copper trades at $13,484 per tonne (IMF via FRED, May 2026), up 41.5% in a year, and U.S. industrial electricity averages 8.66 cents per kWh. Both feed electrified-hardware unit economics.
Steel mill PPI stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. New factory orders are up 2.3% year over year (Census).
