Including-VAT to excluding-VAT is the calculation everyone gets wrong — it’s a division, not a subtraction. Both directions here, with the common European rates one click away.
Because the VAT was added on top of the net. A 100 kr item at 24% sells for 124 kr; taking 24% of 124 off leaves 94.24 — wrong. The correct move is dividing by 1.24, which is exactly what this does.
They’re the standard rates as of mid-2026. Countries also have reduced rates (food, books, hotels…) — if your receipt shows one, type it into the rate box directly. Rates change rarely but do change; the box always wins over the preset.
Yes — 12,5 and 12.5 both work, and thousands separators are fine
(1,234.56 or 1.234,56). A lone comma followed by exactly three digits,
like 1,234, is read as one thousand two hundred thirty-four.
