Description
Subtract shipmentDay from presentationDay and presentationDay from expiryDay.
Trade-finance arithmetic combines supplied fees, exchange factors, timing windows, and reporting bases. A local consistency result does not establish document compliance, contract rights, or bank acceptance.
Subtract shipmentDay from presentationDay and presentationDay from expiryDay.
When to use this tool
Use Letter Of Credit Expiry Presentation Gap when you need one transparent cross-border cost or timing component.
How to use the tool and how it works
- Enter shipmentDay, presentationDay, expiryDay, allowedPresentationDays. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read shipmentPresentationGap, expiryMargin, withinSuppliedDates. Inspect withinSuppliedDates before interpreting the associated values.
Subtract shipmentDay from presentationDay and presentationDay from expiryDay. Mark withinSuppliedDates only for nonnegative shipment gap within allowedPresentationDays and presentation no later than expiry.1

}Limitations and assumptions
- All day coordinates and limits are supplied; document compliance and letter-of-credit rules are not verified.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Review the complete transaction, contract, bank terms, and applicable accounting policies before acting on a partial calculation.
