FX cost check
Paste the lines from your bank statement for payments you sent or received abroad. The check works out the rate the bank gave you on each one, compares it with the European Central Bank reference rate for that day, and adds up the difference.
The check is free and needs no account. Nothing you paste is stored.
See it first. Run it on a sample statement from a fictional furniture importer that pays suppliers in euros and dollars.
Try the sampleMost of what an international payment costs sits in the exchange rate. If the market rate is 1.35 dollars to the pound and the bank gives you 1.32, the 2.2% gap is what you paid, on top of any charge per payment. The statement doesn't show that gap as a number, so the check works it out.
An AI model reads your lines, because every bank lays its statements out differently. The model only copies numbers. Each amount and rate it returns has to appear on the line it came from, or the payment is set aside and listed at the end. The reference rates, markups and totals are all worked out in code.
The reference is the ECB rate for the payment date, published each working day at around 16:00 CET. Rates move during the day, so a markup up to 0.5% shows as green. Between 0.5% and 1.5% shows as amber, and anything over 1.5% as red.
It cannot see the time of day each payment was booked, any charge an intermediary bank took from what your supplier received, or payments where the line shows only the amount in your own currency.
