Comparative Market Analysis Calculator
Actual CMA price adjustment ledger and independent comparable weights, no livecomps, automatic adjustment/appraisal. Safe one-currency minor units and independently applicable comparability; weighted fractional minor units possible.
Description
A comparative-market-analysis ledger adjusts comparable prices before weighting them.
A comparative-market-analysis ledger adjusts comparable prices before weighting them.1
Comparable selection, adjustments and weights require independent market assessment. The calculation and input requirements are explained below.
When to use Comparative Market Analysis Calculator
Enter aligned raw comparable prices, signed adjustment totals and nonnegative weights with positive total.
How to use Comparative Market Analysis Calculator and how it works
- Prepare the measurements or independently established model inputs described below, with matching units and observation scope.
- Enter the required fields and run Comparative Market Analysis Calculator.
- Read the result fields using the formula, output units, signs and ordering explained below.
- Correct any rejected inputs and rerun; interpret the result within the stated model and its assumptions.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualComparableRawPricesMinorUnits | Actual Comparable Raw Prices Minor Units. Use the units and matching context stated in the calculation below. | array of number | Required; other constraints below |
| callerIndependentAdjustmentTotalsMinorUnits | Caller Independent Adjustment Totals Minor Units. Use the units and matching context stated in the calculation below. | array of number | Required; other constraints below |
| callerApplicableComparableWeights | Caller Applicable Comparable Weights. Use the units and matching context stated in the calculation below. | array of number | Required; other constraints below |
Enter aligned raw comparable prices, signed adjustment totals and nonnegative weights with positive total. Prices and resulting adjusted prices must be nonnegative safe integer minor units; adjustments must be signed safe integers. Return adjusted prices and their weighted mean. The weighted indication may be fractional minor units and is not rounded or appraised.
adjusted_i=raw_i+adjustment_i; indication=sum(adjusted_i*weight_i)/sum(weights) Apply the input ordering, units and branch conditions stated above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the calculated or selected fields below. | object |
| result.actualAdjustedComparablePricesMinorUnits | Actual Adjusted Comparable Prices Minor Units. Interpret its unit, sign, order or availability flag as explained above. | array of number |
| result.indicativeWeightedPriceMinorUnits | Indicative Weighted Price Minor Units. Interpret its unit, sign, order or availability flag as explained above. | number |

}Limitations and assumptions
The calculation uses the supplied observations and model inputs. It does not collect measurements, select a reference population or coefficient, or establish that the model applies to the actual case. The stated branch conditions and output units remain part of the result.
All fields require explicit values. Unexpected fields, wrong types, nonfinite numbers and sparse arrays are rejected. Alignment, bounds and supported-token rules are explained above; extremely large inputs or nonfinite results can also fail. Input errors differ from successful false comparisons, unavailable-domain flags and empty match lists.
