My Currency Cost

How it works

Most businesses and private clients are overpaying on currency — and have no idea. Here's how we change that in three steps.

01

Pick your pair and comparison type

Choose whether you want to compare a live spot rate, a forward rate, or a historical rate. Then select your currency pair — GBP, USD, or EUR must be included. Enter the sell amount and the rate you received or are being quoted.

02

We pull the real market rate

We fetch the live mid-market interbank rate — the actual wholesale benchmark, with no markup baked in. For historical comparisons, we retrieve the exact rate for the date and time you specify, accurate to the minute, up to two years back.

03

See exactly what your provider is charging

Instantly see how far your provider's rate sits from the real market rate — expressed in actual money, not just percentages. You'll also see what the same transaction would have cost at a fair, transparent rate.

Don't just know — act.

Once you've seen the numbers, you don't have to accept them.

04

Done something about it yet?

Now you know the real cost, there's no reason to go back to the same provider. We connect businesses and private clients with specialists who charge a transparent, fixed fee — so the rate you see is the rate you pay.

Frequently asked questions

Everything you need to know before you start.

What is My Currency Cost?
My Currency Cost is a free tool that shows you exactly what you are paying for your currency conversions — and how that compares to the real market rate. Most businesses and individuals pay more than they realise. This tool makes the hidden cost visible.
Is it really free?
Yes, completely. There is no charge to use the calculator and no obligation to do anything with the results.
How does the comparison work?
You enter the details of your recent or upcoming currency transaction. The tool compares the rate you received — or are being quoted — against the interbank mid-market rate, revealing the margin your provider is taking, expressed in real money.
What types of transactions can I check?
You can check historical spot trades, live spot rates, and forward contracts.
Who is this tool for?
It is built for two audiences: businesses that make regular international payments, and private clients with overseas financial needs. If you move money across borders, this tool is relevant to you.
Do I need to create an account?
No. You can use the calculator without registering or providing any personal details.
What is the interbank rate?
The interbank rate — sometimes called the mid-market rate — is the rate at which banks trade currency with each other. It is the fairest benchmark for what a currency conversion is actually worth. Most providers add a margin on top of this rate, which is where your real cost comes from.
My provider says they charge no fees. Does that mean I'm getting a good deal?
Not necessarily. Most FX providers build their margin into the exchange rate itself rather than charging an explicit fee. The calculator reveals the true cost regardless of how your provider presents it.
What do I do if the results show I am overpaying?
You can use the contact form to speak to a specialist who can advise on your options. There is no obligation to do anything.
Is my data secure?
Any information you enter into the calculator is used solely to generate your comparison. It is not stored, shared, or used for any other purpose.
Who is behind My Currency Cost?
My Currency Cost is run by a team of UK-based foreign exchange specialists. We work with a carefully selected panel of global currency providers, and our aim is straightforward: to give businesses and private clients an honest view of what their currency is really costing them — and to connect those who want to act on it with providers who will do better.

Important information

Accuracy. Historical rates are sourced from a reliable interbank data provider. Because exchange rates fluctuate constantly, there may be a slight difference based on trading activity within the one-minute period selected.

Comparisons. We show the best available rate from our historical database. The rate you actually received may have differed — better or worse — depending on trade size, currencies involved, and market conditions at the time.

Estimations. All calculations are estimates. We aim for accuracy based on the data available and what you provide, but results should be treated as indicative rather than definitive.
