How do you calculate secure module test load energy cost?

Multiply connected load (kW) by runtime (hr) by the electricity rate. 12 kW x 8 hr x $0.12 = 96 kWh and $11.52 total for the run.

What is the energy cost per unit tested?

Divide total energy cost by units processed. Here $11.52 over 1,000 units is about $0.0115 per terminal — tiny per unit but real at volume.

How much energy does an 8-hour burn-in draw?

At a 12 kW connected load, an 8-hour secure-module soak uses 96 kWh. That is the flat-load estimate before any duty-cycling.

What is the hourly cost of running the test cell?

Total cost divided by runtime: $11.52 over 8 hours is $1.44 per hour of secure-module test load at the given rate.

Should I use my blended or marginal electricity rate?

Use a blended rate ($0.12 here) for standard cost allocation. If the burn-in runs during peak demand windows, a time-of-use marginal rate will give a higher, more accurate figure.

Why does connected load matter more than runtime for cost?

Cost scales linearly with both, but connected load is often where you have design choices — smaller power supplies or fewer simultaneous DUTs cut kW directly, lowering both energy and demand charges.

Payment Terminal & Retail Hardware calculator

Secure Module Test Load Calculator

Secure module test load energy is the electricity a payment-terminal burn-in or HSM soak test rig draws while it exercises secure elements, tamper circuits, and crypto processors under load. Test and manufacturing engineers in retail hardware track it because secure-module qualification runs long — hours of continuous power per rack — and that energy is a real line item in cost-of-test. This calculator turns connected load, runtime, and your electricity rate into kWh and dollars, then divides by units processed so you get a defensible energy cost per terminal. It is the number you cite when someone asks what a burn-in cell costs to run.

What this calculator does

Estimate secure module test load for payment terminal and retail hardware using production-ready inputs so teams can budget energy cost, compare equipment settings, or include electricity in the quote.
Use it when secure module test load in payment terminal and retail hardware is being quoted and energy is a real chunk of the payment terminal and retail hardware cost stack.
It computes total energy in kWh and cost for a secure module test load, plus hourly cost and energy cost per unit processed.

Formula used

Total secure module test load energy cost = secure module test load connected load × secure module test load runtime × blended electricity rate
Energy cost per kWh = total energy cost ÷ units processed during runtime

Inputs explained

Secure module test load connected load:
Secure module test load runtime:
Blended electricity rate:
Units processed during runtime:

How to use the result

Use it to cost a burn-in or soak-test cell, compare test-rig configurations, or allocate energy per terminal in a cost-of-test model.
It assumes the connected load runs steadily for the full runtime; duty-cycled racks or ramped test profiles will draw less than the flat estimate.

Current U.S. benchmarks

As of Apr 2026, industrial electricity averages 8.7 cents per kWh across the U.S. (EIA), up 5.5% from a year earlier. State averages range widely, so plants should confirm against their own tariff.
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).
