Most currency advice for importers ends at "build in a cushion". The obvious question — how big? — usually goes unanswered. Your break-even exchange rate answers it: the single rate at which an order stops making money. Our guide to currency risk covers where the exposure sits and how to reduce it; this one covers the number that tells you whether you have reduced it enough.
- The break-even rate is the exchange rate at which an order returns zero margin.
- It converts a vague worry about the market into one threshold you can watch.
- Calculate it on the unpaid balance, because the deposit is already converted.
- The gap between today’s rate and break-even is your real cushion, as a percentage.
- A cushion under about 3% on a long lead time is thin, and worth acting on early.
What the break-even rate actually is
You have set a selling price. That price supports a certain landed cost and no more. Push the landed cost above it and the order loses money. Because the largest variable input to your landed cost is the rate you convert at, there is one rate at which cost meets price exactly. That is the break-even rate.
It is not a forecast and it does not require a view on the market. It is a property of the order you have already agreed — fixed the moment you set your selling price, and knowable on the day you pay the deposit.
Working it out on one order
The calculation is arithmetic, not modelling. Work in your selling currency throughout, and remember that only the unpaid balance is still exposed — the deposit converted at a rate you already know.
- 1Write down your total expected revenue for the consignment at your planned selling price.
- 2Subtract every cost that is not the balance payment: the deposit you already converted, freight, duty, VAT, clearing, transport and your own overhead allocation.
- 3What remains is the maximum you can afford to spend on the balance, in shillings.
- 4Divide that figure by the balance owed in yuan. The result is your break-even rate.
- 5Compare it to today’s rate and express the gap as a percentage — that is your actual cushion.
| Input | Illustrative figure |
|---|---|
| Expected revenue | KES 2,600,000 |
| All costs except the balance payment | KES 1,150,000 |
| Maximum affordable balance payment | KES 1,450,000 |
| Balance owed to supplier | RMB 75,000 |
| Break-even rate | 19.33 KES per RMB |
| Rate today | 18.10 KES per RMB |
| Cushion | About 6.4% |
What the number changes about your decisions
A cushion of 6% and a cushion of 1.5% call for different behaviour, and without the calculation both simply feel like "some risk". Once you have the percentage, several decisions become straightforward rather than anxious.
- A comfortable cushion means you can pay the balance when production is ready and stop thinking about it.
- A thin cushion is a reason to convert earlier, or to revisit your selling price while the goods are still in production.
- A cushion already consumed is a commercial problem to raise now, not a discovery to make at clearing.
- Across several live orders, the thinnest cushion tells you which one to deal with first.
That last point is where the number earns its keep for an importer running multiple consignments. Rather than watching one rate against a general sense of unease, you have a ranked list: this order has 8% of room, that one has 2%, and the second is where your attention belongs.
Where the calculation misleads
The method is only as good as the costs you feed it, and there are three ways importers arrive at an over-optimistic number.
- 1Using a mid-market rate rather than the rate you will actually be offered — the spread is a real cost and belongs in the calculation.
- 2Omitting the charges that appear late: clearing agent fees, demurrage, and any shortfall an intermediary bank deducts in transit.
- 3Assuming the entire consignment sells at full price, when the revenue line should reflect the discounting you realistically expect.
Each of these flatters the break-even rate, which makes the cushion look larger than it is. If you are going to be wrong, be wrong in the conservative direction: a slightly pessimistic break-even rate costs you nothing, while an optimistic one removes the warning exactly when you needed it.
Frequently asked questions
How often should I recalculate it?
Once per order is usually enough, at the point the deposit is paid and the costs are known. Recalculate if something material changes — a freight quote moves, duty is assessed differently, or you revise your selling price.
Does this replace hedging?
No. It tells you how much protection you need, which is the question you have to answer before deciding whether any hedge is worth its cost. For most SME orders the answer is that disciplined pricing and timing are sufficient.
What if the rate passes my break-even before I pay?
Then you know, in advance, that the order as priced no longer works — while you still have options. You can adjust the selling price, accept a thinner margin deliberately, or discuss timing with the supplier. The value is in finding out before the goods arrive, not after.
