Nixie Tube Calculator Formula

Q = F / (P – V)

Source: Investopedia – Break-Even Point Definition

Variables:

  • Quantity (Q): The number of nixie tube units you need to sell to cover all costs.
  • Price (P): The selling price for each individual nixie tube clock or device.
  • Variable Cost (V): The cost to produce one unit (materials, labor, tube cost).
  • Fixed Costs (F): Costs that don’t change with production (rent, equipment, marketing).

What is Nixie Tube Calculator?

A Nixie Tube Calculator in this context is a specialized business tool designed for engineers and hobbyists who manufacture high-end vintage electronics. Because Nixie tubes (cold cathode neon displays) are expensive and often “new-old-stock,” understanding the financial threshold of production is critical.

This calculator uses the Break-Even Point (BEP) logic to help you decide if a specific production run of Nixie clocks or thermometers is financially viable. By balancing the high cost of components against your market price, you can determine exactly how many units must be sold to avoid a loss.

How to Calculate (Example)

  1. Assume your Fixed Costs (F) for a laser cutter and workspace are $2,000.
  2. Your Variable Cost (V) per clock (including 6 tubes) is $80.
  3. You plan to sell each unit at a Price (P) of $200.
  4. Subtract V from P: $200 – $80 = $120 (Contribution Margin).
  5. Divide F by the margin: $2,000 / $120 = 16.67 units. You must sell 17 units to break even.

Frequently Asked Questions (FAQ)

How do I lower my Break-Even Point?

You can lower the BEP by reducing fixed costs, sourcing cheaper tubes (lowering V), or increasing the premium price (P) of your device.

Why is my calculation showing a negative number?

If your Variable Cost (V) is higher than your Selling Price (P), you are losing money on every unit sold, making it impossible to reach a break-even point.

Does this include shipping costs?

Shipping to customers should be included in the Variable Cost (V) per unit for accurate results.

What is a typical margin for Nixie Tube electronics?

Due to the artisanal nature and scarcity of parts, many creators aim for a 50-70% margin per unit.
