Many financing requests from traders, importers and exporters start with a number that is either too low or impossible to justify. Too low, and the business runs out of cash mid-shipment. Too high, and lenders see a request that does not match the trade. The right number comes from the cash cycle of the shipment, not from turnover. This guide shows how to calculate it, step by step, using only your own contracts and quotes, so every figure in the request can be traced to a document a lender can check.

**Short answer:** put every payment and receipt for one shipment on a timeline, find the largest negative cash balance, subtract what you fund yourself, add a buffer for delays, then multiply by the number of shipments that overlap at your busiest point.

## Step-by-step: sizing your trade finance need

1. ### Map the cash cycle of one shipment  
Write down the dates of every event: contract, supplier deposit, balance payment, loading, arrival, customs clearance, delivery to the customer, invoice and collection. Use the payment terms in your actual contracts, not best-case assumptions.
2. ### List every cash outflow before collection  
Include the goods, freight, cargo insurance, inspection, duties and import taxes, port, storage and transport charges, bank and LC charges, and the cost of the financing itself. See our guide to [cargo insurance](https://blog.financely.io/commodity-cargo-insurance-coverage-claims-and-trade/) for one cost that is often missed.
3. ### Fix when cash comes in  
Record when the customer pays: at delivery, against documents, or on credit terms after invoice. If several customers buy one shipment, show each receipt separately.
4. ### Find the peak funding gap  
Add the cash flows day by day. The running total falls as you pay costs and rises as customers pay. The lowest point is the peak gap, the most cash tied up in the trade at one time.
5. ### Deduct your own contribution  
Subtract the cash you will put into the trade. Lenders expect the business to carry part of the risk, so show the contribution clearly. Our note on [presenting sources and uses](https://blog.financely.io/how-to-present-sources-and-uses/) shows a clean format.
6. ### Add a buffer for delays  
Re-run the timeline with a late vessel, slow customs clearance and a customer who pays late. The difference between the base case and the delayed case is your buffer. Our article on [why profitable trades still run out of liquidity](https://blog.financely.io/why-profitable-commodity-trades-still-run-out-of-liquidity/) explains why this step matters.
7. ### Scale to overlapping shipments  
If a new shipment starts before the last one is collected, the gaps stack. Lay the cycles side by side for your busiest season and add the gaps at the point of maximum overlap. That is the size of a revolving facility, not your annual turnover.
8. ### Match each gap to the right instrument  
Supplier payments may suit an import LC or supplier payment facility. Goods in storage may suit inventory finance. Customer credit terms may suit receivables finance. A [borrowing base](https://blog.financely.io/how-to-calculate-a-borrowing-base/) can combine inventory and receivables in one facility.

## Template: one-shipment cash timeline

Fill in your own dates and amounts. The cumulative column is what matters.

| Event                           | Day                   | Cash out                 | Cash in        | Cumulative position                         |
| ------------------------------- | --------------------- | ------------------------ | -------------- | ------------------------------------------- |
| Supplier deposit                | Contract date         | Deposit amount           |                | Minus deposit                               |
| Supplier balance or LC payment  | Before or at shipment | Balance and bank charges |                | Running total                               |
| Freight, insurance, inspection  | Around loading        | Each cost                |                | Running total                               |
| Duties, taxes, port and storage | On arrival            | Each cost                |                | Running total                               |
| Delivery and invoice            | Delivery date         | Local transport          |                | Running total (often the peak gap)          |
| Customer payment                | Per payment terms     | Finance costs            | Invoice amount | Back to positive if the trade is profitable |

## Common sizing mistakes

- Sizing to annual turnover instead of the peak gap.
- Using supplier and customer terms you hope for rather than those you have signed.
- Leaving out duties, taxes and storage, which can be paid well before the sale.
- Ignoring foreign exchange where you buy and sell in different currencies.
- Assuming the lender will fund every cost, including your margin.

## What lenders check in your calculation

A financier will test each date and cost against documents. Supplier terms should match the pro forma invoice or contract. Freight and insurance should match quotes. Customer payment terms should match the sales contract or purchase order. Expect questions on what happens if the customer pays late, if the goods arrive damaged, or if the price of the goods falls while they are in transit or storage. The lender will also look at whether it can control the goods or the receivable at each stage, because that decides how much it can advance against them.

## One shipment or a program?

A single trade is usually financed transaction by transaction, which is slower and often more expensive per shipment. Once you can show several completed cycles with the same suppliers and customers, the same calculation supports a request for a revolving line sized to your peak overlap. Keep the timelines for every completed shipment: they become the track record a lender asks for.

## Turning the number into a request

A lender wants to see the timeline, the peak gap, your contribution, the buffer and the security behind each part of the funding. Present it with the contracts that support each date. Financely uses the same build when preparing trade finance requests for lenders, as an advisor and arranger. Lenders make their own credit decisions, and no amount is promised.

## Frequently Asked Questions

### How do I calculate how much working capital a trade needs?

Map every payment and receipt for one shipment on a timeline, add them up day by day, and take the largest negative balance. That peak gap, less your own contribution and plus a delay buffer, is the financing need for one shipment.

### Why is the peak gap more useful than the total cost?

Because cash goes out and comes in at different times. The peak gap is the most money tied up at any one moment, which is what a facility has to cover. Adding up every cost ignores timing, and the timing of each payment decides how much cash the trade really needs.

### How do I size a facility for several shipments?

Work out how many shipment cycles overlap at the busiest point in your year and add their funding gaps at that point. A revolving facility is sized to that peak, not to annual turnover. Keep the timeline for every completed shipment, because it becomes the track record a lender asks for.

### Will a lender finance the whole amount?

Usually not. Most financiers expect the trader to contribute part of the cost and advance against the value of goods or receivables they can control. The contribution required depends on the lender, the goods and your track record, so show your own contribution clearly in the request.

### Which costs do traders forget?

Freight, insurance, inspection, duties and taxes, port and storage charges, bank and LC charges, financing costs, and foreign exchange differences. Each one adds to the peak gap if paid before the customer pays. Leave one out and the request comes in too low, which can leave the business short of cash mid-shipment.
