Payment Term Risk Estimator

What this tool does

This calculator estimates your expected loss percentage when extending credit to a buyer under different payment terms. It combines country-level default rates, buyer credit history, transaction size, and tenor to produce a risk-adjusted loss estimate for five common payment structures: open account, documents against payment, documents against acceptance, letters of credit, and supply chain finance.

The output helps you compare the cost of non-payment risk across terms before you quote or negotiate. If your expected loss on 90-day open account exceeds your margin, you know to tighten terms, require security, or price the risk into the deal.

Who should use it

AR managers evaluating new buyer credit limits, trade finance leads structuring deals, and exporters deciding whether to accept extended payment terms. Use it when onboarding a new buyer, entering a higher-risk market, or reviewing existing limits after a buyer's financials change. Treasury teams can also use it to stress-test portfolio exposure by running multiple buyer profiles.

Inputs

• Buyer country: Select the buyer's country of domicile. The tool maps this to a risk band (1 to 4) using sovereign and commercial default statistics from Allianz Trade.
• Buyer credit tier: Choose from Strong, Adequate, or Weak based on your internal scoring or external bureau data. Strong corresponds to investment-grade equivalent; Weak corresponds to distressed or no-history buyers.
• Transaction value (USD): Enter the shipment or invoice value. Concentration effects apply: larger single exposures carry higher loss severity assumptions.
• Payment term (days): The number of days from invoice date (or shipment date, depending on your incoterm) to due date. Enter 30, 60, 90, or 120.
• Payment method: Select one of Open Account, D/P (documents against payment), D/A (documents against acceptance), Confirmed LC, or SCF (supply chain finance with a rated obligor).
• Credit insurance coverage (%): If you carry trade credit insurance, enter the indemnity percentage (commonly 90%). Leave at 0 if uninsured.

Assumptions

The model assumes that country risk bands remain stable over the payment tenor. It does not account for intra-tenor political events, currency crises, or sanctions changes that could spike default rates mid-shipment. Buyer credit tiers are treated as static; the tool does not dynamically adjust for real-time financial deterioration.

Recovery rates are set at industry medians: 45% for open account, 55% for D/P, 50% for D/A, 95% for confirmed LC (reflecting bank obligation), and 85% for SCF (reflecting the financing bank's credit substitution). These are averages from Atradius claims data and may not match your actual recovery experience in specific jurisdictions or sectors.

Limitations

This tool does not replace a full credit assessment. It does not pull live bureau scores, verify buyer financials, or check sanctions lists. The output is a statistical estimate, not a guarantee of loss or safety.

The model does not distinguish between sectors. A machinery exporter selling to a construction buyer in Turkey and an electronics exporter selling to a retailer in Turkey will see the same country-risk input, even though sector default rates differ. For sector-specific adjustments, consult your credit insurer's underwriting guidance or apply your own multiplier.

How results are calculated

The expected loss formula is: EL = PD × LGD × EAD, where PD is the probability of default, LGD is loss given default (1 minus recovery rate), and EAD is exposure at default (your transaction value).

PD is derived by starting with a base country default rate (from Allianz Trade's country risk grades, ranging from 0.1% for AA-rated markets to 6%+ for D-rated markets), then adjusting for buyer credit tier (Strong: 0.5× multiplier; Adequate: 1.0×; Weak: 2.5×), and scaling by tenor (each 30-day increment beyond 30 days adds 15% to PD, reflecting the time-decay of creditworthiness certainty).

Payment method modifies LGD. Open account has no documentary protection, so recovery depends entirely on post-default collection. D/P provides some leverage (documents release only against payment), reducing LGD. D/A is weaker than D/P because the buyer obtains documents on acceptance, not payment. Confirmed LCs shift default risk to the confirming bank, dropping LGD to near zero for bank-risk-only scenarios. SCF, where a rated bank discounts the receivable without recourse, similarly substitutes bank credit for buyer credit.

If credit insurance is present, the model reduces net EAD by the coverage percentage, then applies the insurer's typical claims-payment rate (assumed 98% for investment-grade insurers).

Disclaimer

This tool provides indicative estimates based on published default and recovery statistics. It is not financial, legal, or credit advice. Actual loss outcomes depend on buyer-specific factors, contract terms, and enforcement conditions that the model cannot capture. Before extending credit, verify buyer financials, check sanctions and denied-party lists, and consult your credit insurer or legal counsel as appropriate.
