When to use Rap List Discount Application
Use this tool to apply caller supplied dated list quotation, negotiated discount, currency conversion and transaction tax; no proprietary Rap list publication, current rates or tax/legal compliance assumption.
Prepare the gemstone measurements, spectra or comparison data and any supplied calibration parameters. Check units, reference conditions and record alignment.
How to use Rap List Discount Application and understand its results
- Prepare the gemstone measurements, spectra or comparison data and any supplied calibration parameters. Check units, reference conditions and record alignment.
- Enter quotedListRatePerCarat, stoneCaratMass, negotiatedDiscountFraction, transactionCurrencyPerQuoteCurrency, transactionTaxFraction using the field table and calculation rules, then run the tool.
- Read discountedNetTransactionQuote, transactionTaxAmount, totalTransactionQuote. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| quotedListRatePerCarat | Quoted list rate per carat | number | Required |
| stoneCaratMass | Stone carat mass | number | Required |
| negotiatedDiscountFraction | Negotiated discount fraction | number | Required |
| transactionCurrencyPerQuoteCurrency | Transaction currency per quote currency | number | Required |
| transactionTaxFraction | Transaction tax fraction | number | Required |
Enter nonnegative rate, carat mass and tax fraction, positive currency conversion and discount in [0,1]. Return net transaction quote, tax amount and total in the transaction currency. Zero mass or complete discount gives zero totals.
net=list rate × carats × (1−discount) × currency factor; total=net(1+tax fraction) Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| discountedNetTransactionQuote | Discounted net transaction quote | number |
| transactionTaxAmount | Transaction tax amount | number |
| totalTransactionQuote | Total transaction quote | number |

}Limitations and assumptions
No proprietary price list, live exchange rate, tax rule or market valuation is provided.
Numeric inputs and returned numeric values must be finite; an unrepresentable returned value produces an error. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Price Per Carat Interpolation: Interpolate caller comparable per-carat quotations within observed mass calibration and compute total quote; no live market catalog, implicit magic-size smoothing approval or appraisal assertion. For a complementary task, use Appraisal Retail Replacement Value: Build caller replacement scenarios from comparable stone, setting and restoration quotes with explicit currency/policy cost additions; not a professional appraisal, wholesale resale or guaranteed insurer valuation.
