NPI, DFM/DFA & Engineering Change calculator

Design Verification Cost Calculator

Design verification (DV) cost is the total spend to prove a design meets its requirements before it transfers to production - the test runs, the lab time, and the one-time fixturing. Design and quality engineers use it during NPI gate reviews to budget a DV campaign and to defend the cost of a robust test plan against schedule pressure. It separates the variable cost that scales with test count from the fixed fixturing adder, which is what makes DV spend predictable. Getting this wrong means either an underfunded test plan that lets defects escape or a gold-plated campaign that blows the launch budget.

What this calculator does

  • Estimate design verification cost from the number of tests, cost per test, the in-scope share, and setup and fixturing cost.
  • a verification lead needs to budget a DVP&R test campaign for a new design or engineering change.
  • Computes total design verification cost as in-scope test count times cost per test plus fixturing, and divides by tests to give a per-test cost.

Formula used

  • Total design verification cost = verification tests × cost per test × in-scope share + test setup and fixturing
  • Cost per verification test = total design verification cost ÷ verification tests

Inputs explained

  • Verification tests executed:
  • Cost per verification test:
  • Share of tests in DV scope:
  • Test setup and fixturing cost:

How to use the result

  • Use it when budgeting a DV test plan at an NPI design-verification gate or comparing in-house versus outsourced test campaigns.
  • It assumes a single average cost per test; mixed campaigns with cheap functional checks and expensive environmental or HALT runs need separate line items.

Common questions

  • How do you calculate design verification cost? Multiply tests by cost per test by the in-scope share, then add fixturing. Here 24 tests x $650 x 85% + $5,000 = $18,260 total.
  • What is design verification cost per test? Total DV cost divided by tests run. In the example, $18,260 over 24 tests is about $760.83 per test once the fixed fixturing adder is spread across the campaign.
  • Why split variable and fixed verification cost? The variable portion ($13,260 here) scales with test count, while fixturing ($5,000) is a one-time setup. Separating them shows how per-test cost falls as you run more tests on the same fixture.
  • What does the in-scope test share do? It scales the variable cost to only the tests that count toward this DV budget. At 85%, you pay for 85% of the nominal test cost before adding fixturing.
  • What is a good design verification cost? There's no universal number - it depends on requirement count and risk class. The useful benchmark is per-test cost: drive it down by amortizing fixturing across more verification runs.
