How to Calculate LC Cost: Complete Breakdown of Issuance, Confirmation & Discrepancy Fees

What is the True Cost of a Letter of Credit?

Most traders hear "0.125% per quarter" from their bank and think that's the total LC cost. It's not. A typical Letter of Credit involves seven separate charges - some from the issuing bank, some from the seller's bank, some flat fees, and many traders are surprised to discover they're paying for something called a "discrepancy fee" even after the LC is paid.

This guide breaks down every charge, shows you real examples across currencies, and explains how Field 71B in the MT700 determines who actually pays. By the end, you'll know exactly what your LC should cost before you negotiate with your bank.

The Seven Components of LC Cost

No two banks charge identically, but the structure is universal under UCP 600. Here are the seven cost drivers:

1. Issuance Fee

The issuing bank's charge for opening and managing the credit. This is paid by the buyer (applicant).

• Typical range: 0.125% – 0.25% per quarter (90-day period)
• Basis: Percentage of the LC amount
• Calculation: LC Amount × (Issuance Rate ÷ 4 quarters per year) × (Tenor in Days ÷ 90)
• Example: USD 1,000,000 LC at 0.15% per quarter for 90 days = USD 1,000,000 × 0.15% = USD 1,500

What affects the rate? Issuing bank's country risk (US/EU bank: lower %; emerging market bank: higher %), buyer's creditworthiness, and competitive pressure. Top-tier banks in low-risk countries often quote 0.125%; smaller banks or higher-risk countries quote 0.20–0.25%.

2. Confirmation Fee

When an additional bank (the confirming bank) adds its own undertaking to pay, it charges a fee. This is optional but common when the issuing bank or country risk is high. Typically paid by the buyer, but negotiable.

• Typical range: 0.15% – 0.40% per quarter
• Basis: Percentage of LC amount, same tenor basis as issuance
• Calculation: Same formula as issuance fee, but higher rate due to added risk
• Example: USD 1,000,000 LC confirmed at 0.25% per quarter for 90 days = USD 2,500

When to confirm? When the issuing bank is in a high-risk country (sanctions concerns, sovereign risk), when the issuing bank itself is not top-rated, or when the buyer's country presents credit risk. Confirmation gives the beneficiary (seller) an additional strong payment guarantee.

3. Advising Fee

The advising bank (in the seller's country) charges a flat fee to authenticate and advise the LC. Usually for the seller's account.

• Typical range: USD 75 – 150 flat
• Basis: Per LC advised, not per amount
• Notes: This fee is charged once, regardless of LC value; small fixed cost

4. Negotiation / Handling Fee

When the seller's bank (or any nominated bank) examines and processes the LC documents, it charges a handling fee. Paid by the seller (beneficiary).

• Typical range: 0.10% – 0.25% of the drawing amount
• Basis: Percentage of the invoice / LC amount drawn
• Example: USD 1,000,000 drawn at 0.15% = USD 1,500
• Timing: Deducted when the bank makes payment to the seller

Why does it vary? Banks in higher-risk countries charge more; established relationships with lower rates; high-value transactions sometimes get volume discounts.

5. Reimbursement Fee

When the nominating/paying bank needs to be reimbursed by the issuing bank, a reimbursement charge applies. This is an inter-bank cost, typically for the buyer's account, though charged through the seller's bank.

• Typical range: USD 100 – 300 flat (or 0.05% of amount)
• Basis: Usually flat fee per transaction

6. SWIFT / Courier Charges

Cost of transmitting the LC message between banks (SWIFT MT700) and sending physical documents by courier. Split between buyer and seller depending on Field 71B.

• Typical range: USD 20 – 50 per transmission
• Includes: Initial LC, amendments, advice of payment

7. Discrepancy Fee

When the examining bank finds a discrepancy in the documents, it charges a fee for the extra work to contact parties and obtain waivers. This is the most commonly overlooked cost.

• Typical range: USD 50 – 150 per set of documents
• Charged to: Usually the beneficiary (seller), sometimes shared
• When charged: Even if the discrepancy is waived and the LC is eventually paid
• Frequency: ICC data: 60–80% of presentations have at least one discrepancy on first submission

Important: Under UCP 600 Article 14, the examining bank must notify the presenting bank of discrepancies within 5 banking days. If the discrepancy is waived (buyer agrees to pay anyway), the discrepancy fee is still charged for the bank's review work.

Amendment Fees (Additional Costs)

If either party requests changes to the LC after issuance, the issuing bank charges an amendment fee per Field 707 (Amendment notification). This is for the buyer's account.

• Typical cost: USD 50 – 100 per amendment
• Common amendments: Extending shipment date, changing beneficiary, increasing amount, relaxing inspection requirements
• Minimize by: Getting the LC right the first time - review it carefully before issuance

Real Example: USD 500,000 LC Confirmed for 90 Days

Cost Allocation Under Field 71B (MT700)

Field 71B in the MT700 specifies who pays which charges. Here are the three common patterns:

Negotiation tip: Field 71B is negotiable at LC issuance. If you're the seller and want to minimize your cost, push for "All charges outside [issuing country] for account of applicant." If you're the buyer and confident in your documents, push for "All charges for account of beneficiary" to reduce your own cost exposure.

Currency Day-Count Impact: ACT/360 vs ACT/365

LC fees are typically calculated on a per-quarter (90-day) basis, but the day-count convention differs by currency. This can shift your total cost by 1–2% on usance transactions.

Example: A 90-day LC in GBP at 0.25% per quarter costs GBP 2,532 instead of GBP 2,500 (assuming 360-day year) - a difference of GBP 32 on a GBP 1,000,000 LC. On large trades, this adds up. Our LC Cost Calculator automatically adjusts for the correct day-count convention by currency.

How to Minimize LC Cost

For Buyers (Applicants)

• Negotiate issuance and confirmation rates upfront. Bank competition is real; get quotes from 2–3 banks before committing.
• Request unconfirmed LCs when possible. If the issuing bank is top-rated and in a low-risk country, you can skip confirmation and save 0.15%–0.40% of the LC amount.
• Push for longer validity periods to reduce per-quarter costs. A 180-day LC spreads the issuance cost over two quarters, reducing total cost.
• Negotiate Field 71B heavily. "All charges for account of beneficiary" shifts most costs to the seller, reducing your all-in cost.
• Use revolving LCs for repeat shipments. Instead of opening a new LC for each monthly shipment, a revolving LC (auto-reinstates) reduces amendment costs.
• Get the LC terms right the first time. Every amendment costs USD 50–100; a poorly drafted LC can cost you USD 200+ in amendments alone.

For Sellers (Beneficiaries)

• Insist on confirmed LCs from high-risk issuers. Confirmation protects you; the cost (borne by buyer under most terms) is worth the security.
• Negotiate for "All charges outside [country] for account of applicant." This minimizes your discrepancy fee exposure.
• Present documents carefully to avoid discrepancies. Use our LC Discrepancy Scanner to self-check before submitting. One discrepancy fee (USD 75–150) can be avoided with 10 minutes of preparation.
• Understand the presentation timeline. You have 21 days (UCP 600 default) to present documents after shipment. Missing this window triggers an automatic rejection and is one of the top discrepancy reasons.

Comparing Quotes: Build Your LC Cost Model

Use this checklist to compare bank quotes accurately:

1. Standardize tenor and confirmation. Compare all quotes for the same LC (e.g., 90-day confirmed). Apples to apples only.
2. Get each bank's rate sheet for issuance, confirmation, negotiation, advising, reimbursement. Don't accept "negotiable"-pin down rates.
3. Include hidden fees. Ask: "Do you charge for amendments? SWIFT? Courier? Discrepancy waivers?"
4. Calculate with the correct day-count convention (ACT/360 for USD; ACT/365 for GBP/INR).
5. Model Field 71B allocation. See where your costs fall: buyer vs seller account.
6. Use our LC Cost Calculator. Plug in each bank's rates and see the total side-by-side. The tool handles day-count and multi-currency automatically.

Typical result: You find that Bank A quotes 0.15% issuance + 0.20% confirmation, while Bank B quotes 0.12% + 0.18%. On a USD 5,000,000 LC for 90 days, that's a difference of USD 1,500. Over a year of 12 shipments, that's USD 18,000 in total savings. It's worth 30 minutes of negotiation.

Frequently Asked Questions

Q: Do I have to pay a discrepancy fee even if the LC is eventually paid?

A: Yes. Under UCP 600 Article 14, the examining bank charges for the administrative work of notifying you of the discrepancy, even if you waive it and the LC is paid anyway. It's a "review fee," not a penalty. Plan for this cost if you're in a high-discrepancy commodity (coal, grain, metals often have quality disputes that trigger first-submission discrepancies).

Q: What if I issue an LC but don't use it?

A: You still pay the issuance and confirmation fees (if confirmed). The bank has taken on contingent liability for the full LC amount, so it charges even if you don't draw. Some banks charge a small additional "cancel" fee (USD 50–100) to discharge the LC early.

Q: Can I negotiate the discrepancy fee?

A: Limited. Discrepancy fees are usually fixed at USD 50–150 depending on bank and market. You can't avoid them in contracts, but you can avoid triggering them by checking your documents carefully before submission. Use the LC Discrepancy Scanner.

Q: Why is confirmation so expensive (0.25% or more)?

A: The confirming bank is adding its own payment undertaking, which means it takes on credit risk. If the issuing bank fails to pay, the confirming bank must pay the seller. The extra 0.10%–0.15% reflects that risk. On high-risk countries (emerging market issuers), confirmation is worth the cost for seller protection.

Q: If I use usance (deferred payment) instead of sight, do LC costs change?

A: Yes. Usance LCs extend over a longer period (e.g., 90 or 180 days from sight), so issuance and confirmation fees are typically charged for each quarter. A 180-day usance LC costs roughly 2× the fee of a 90-day sight LC. However, you get the benefit of extended payment terms. Use the Usance Interest Calculator to compare the cost of discounting usance vs paying sight LC charges upfront.

When to Use LC vs Other Payment Terms

LC cost is real money. Sometimes a cheaper payment method makes sense:

• Use LC: High-value transactions, unknown buyer, high-risk country, or commodity with quality disputes (need documentary protection).
• Use Documentary Collection (D/P): Established buyer relationship, lower transaction value, time-sensitive shipment (avoids LC delays). Cost: ~USD 250–500 flat fee.
• Use Open Account + SBLC: Repeat buyer, strong credit, but need backup security. Seller gets open account efficiency; buyer gets deferral. SBLC is usually 1–3% per annum on the guaranteed amount (much lower than full LC if only securing part of transaction).

This guide is for trade finance education. Always confirm LC terms, costs, and Field 71B allocation with your bank before issuance. Refer to the current UCP 600 (ICC Publication 600, 2007) for authoritative rules.
