Market values: FMV, MPV & MSV

The Evaluator publishes three complementary values for every part & condition combination it can price. Together they describe a price corridor and how confident the platform is in it.

Value

Meaning

When to use it

FMV

Fair Market Value — a strategic, neutral reference value. No company-specific supply or demand context.
Long-term reference; benchmarking;

baseline for comparison.

MPV

Market Purchase Value — lower bound of the typical market price corridor.
What a buyer can realistically

expect to pay.

MSV

Market Sales Value — upper bound of the typical market price corridor.
What a seller can realistically

expect to obtain.

How MPV and MSV are derived

MPV and MSV are derived from the observed weighted price dispersion around the FMV. A spread is calculated from the interquartile range (IQR) of recent transactions divided by the median, and clamped between the minimum and maximum spread configured for the company.

\[ \begin{align}\begin{aligned}\text{MPV} = \text{FMV} \times (1 - \text{spread})\\\text{MSV} = \text{FMV} \times (1 + \text{spread})\end{aligned}\end{align} \]

For parts with thin transaction history, the spread is calibrated against comparable parts within the same material domain and fleet so that the MPV/MSV corridor remains stable.

Company calibration

Company administrators can fine-tune the spread boundaries used for their company in Settings → Company → Evaluator:

  • Min spread — minimum width of the corridor (default 0.10 = 10%).

  • Max spread — maximum width of the corridor (default 0.40 = 40%).

  • Spread override — optional fixed spread that bypasses the IQR-based calculation. Leave empty to use the automatic logic.

See Company Settings for the full settings walkthrough. Changes take effect with the next monthly recalculation cycle (1st of the following month).

FMV Quality scorecard

Each FMV is rated on three orthogonal dimensions, each scored as High, Medium or Low:

Dimension

What it measures

Data basis

How much real market evidence is available. Derived from the FMV stage and the number of transactions used. High requires stage ≤ 4 with at least six transactions.

Data freshness

How recent the evidence is. High if at least one transaction exists in the last 12 months; Medium in the last 24 months.

Price

Whether the FMV sits between MPV and MSV across the available

consistency

conditions. High if no inversions; otherwise Medium or Low depending on how many conditions are inconsistent.

The combined FMV Quality is presented as one chip per part:

  • High — every dimension at its best level.

  • Low — any single dimension at its worst level.

  • Medium — anything between.

Quality dimensions and the combined rating are stored alongside the FMV at every calculation cycle, so the historical record reflects the quality that was active at the time.

Where the values appear

  • Single-part evaluation (Search) — Price Summary matrix per condition.

  • Material lists (Lists) — totals at the list level, plus per-row values in the part table.

  • Decision Support (Decision Support) — used as the reference for quote validation and pricing recommendations.

  • Evaluation KPI API — exposed alongside FMV. The fmvStage field is included so API consumers can interpret the methodology and data basis.
