Hi all,

I've observed a glitch or issue with the Amazon "FBA Calculator" today. Specifically, when I input any ASIN, the FBA fulfilment fee initially displays the correct charge. For instance, for one of my ASINs, the FBA fee correctly shows as "Fulfillment cost £2.44". However, any adjustments made within the calculator, such as changing selling price, results in the FBA fulfilment cost displaying as £6.22 and it will not revert back to 2.44. This figure does not align with the actual or expected charge. I've also set the country to GB so this issue shouldn’t be occurring,

Other indicators, including the Fulfillment by Amazon rates card, estimates on my FBA inventory screen, and charges within SKU economics, consistently reflect a cost of around £2.44. This discrepancy appears to be exclusive to the calculator, and I suspect it may be related to the "EFN" (European Fulfillment Network) cost as 6.22 would be accurate for this product via EFN, however, I’d love to know why it is changing to this?

Even if I try to calculate via the “define product” option the same issue occurs.

Despite having all other parameters set appropriately, the calculator continues to show the cost as £6.22 after any adjustments are made within the calculator. When loading a product without making adjustments, the initial display is £2.44. However, after making minor changes, like adjusting the selling price, the fee persists as £6.22, despite the original indication of £2.44.

I rely on this calculator regularly as I am sure many of you do, and this issue has surfaced only today. I urgently need to use it for my business operations, and I hope there isn’t anything wrong with the calculation of fees on my amazon as a result, so I kindly request assistance in identifying and resolving this recent glitch. Has anyone else experienced this issue?
