The ladder

The middle column is what the rule gives you standing in a market. The right column is the real number, so you can see exactly where the shortcut costs you.

Like Australia, displayed prices are tax-inclusive and tip-free, so what you read is what you pay.

When this rule stops working

Rules of thumb rot quietly. This one holds while the rate stays roughly between 2.05 and 2.15 NZD to the franc. Outside that band a different divisor becomes the better one to memorise. We regenerate this page from the live rate feed, so the date above tells you how fresh the number is — if you are reading this a long way after August 2026, check it before you rely on it.
