**Outputs:**

#### Expected retest cost

**Key:** expected_retest

**Format:** currency

#### Total compliance cost over life

**Key:** total

**Expr:** test_fees + listing + surveillance * years + expected_retest

**Format:** currency

**Primary:** true

#### Lifetime units

**Key:** life_units

**Expr:** volume * years

**Format:** integer

#### Compliance cost per unit

**Key:** per_unit

**Expr:** total / life_units

**Format:** currency

**Primary:** true

#### One-time share of total

**Key:** one_time_share

**Expr:** (test_fees + listing + expected_retest) / total * 100

**Format:** percent

#### Volume for under $1 per unit

**Key:** breakeven

**Expr:** total / years

**Format:** integer

**Description:** Annual volume at which compliance cost drops to $1 per unit.

**Chart:**

#### Compliance cost per unit vs annual volume

**Type:** line

**X:** volume

**From:** 200

**To:** 20000

**Steps:** 40

**Series:**

- per_unit

**Disclaimer:** Fees vary by laboratory, standard, scope and market. Replace the defaults with quotes. The expected retest cost is a probability-weighted estimate, not a prediction.

## Content

**Intro:** Compliance is a fixed cost that is easy to hide in overhead, which makes low-volume products look more profitable than they are. This calculator spreads every certification cost over lifetime volume so the per-unit figure can go into the quote.

**Sections:**

#### How to use it

**Body:** Gather quotes for the test campaign and the certification body fees, then add the annual follow-up cost for surveillance and listing. Estimate the chance that a design change or a failed test forces a retest, and the cost if it does. Enter product life and annual volume. The result is the total cost across the life and the compliance cost per unit. The chart sweeps annual volume so you can see the point where more units stop making a visible difference.

**Bullets:**

- Use quotes, not list prices
- Include every target market
- Keep the retest probability honest, use history

#### The arithmetic

**Body:** Total cost is initial testing plus listing plus annual surveillance times years, plus the probability-weighted retest cost. Per-unit cost is that total divided by annual volume times years. The one-time share shows how much of the spend is front-loaded, which matters for cash planning and for decisions about whether to certify at all in a small market. The last output gives the annual volume at which compliance cost per unit reaches one currency unit, a quick way to compare markets of very different size.

**Bullets:**

- Total = tests + listing + surveillance x years + expected retest
- Per unit = total / (volume x years)
- Expected retest = probability x campaign cost

#### Worked example

**Body:** With $18,000 in tests, $6,500 in listing fees, $2,400 per year in surveillance over four years and a 30% chance of a $7,000 retest, total cost is about $36,200. At 3,000 units a year the product sells 12,000 units over its life, so compliance adds about $3.02 per unit. At 600 units a year the figure rises to about $15 per unit, which may change the price or the decision to enter that market.

#### Common mistakes

**Body:** Teams often leave out surveillance, fail to include the cost of engineering time during the test campaign, or assume the first test will pass. Another is amortising over an optimistic volume forecast. Use the lower of the sales and operations forecast and the contractual minimum. Put the resulting per-unit figure into the standard cost of the item so margin reports reflect it.

**Cta:** Netray can help you bring certification costs into item costing in your ERP so compliance is visible in margin analysis rather than buried in overhead.

**Faq:**

#### Should I include internal engineering time?

**Answer:** Yes, if you want a full cost. Fees from labs and certification bodies are only part of the spend. Add internal hours for sample builds, test support and documentation at a loaded rate if the decision depends on it.

#### How do I estimate retest probability?

**Answer:** Use your own history of first-pass rates for similar products and standards. If you have none, start at 20% to 40% for new designs in electrical or EMC testing and refine after the first campaign.

#### What product life should I use?

**Answer:** Use the planned sales life plus any period you must keep the certification active for spares and service. Surveillance often continues as long as the listing is maintained.

#### Does the result include customs or tariffs?

**Answer:** No. It covers testing, certification, surveillance and expected retests only. Duties, freight and any recycling or take-back fees should be added separately.
