How much is it altogether?
'Quant'è' — KWAN-teh. The apostrophe contracts 'quanto è'. Say it as one word.
Use at the till when buying multiple items to hear the total before paying. Natural and common in all shopping contexts.
'Quant'è' is an elision of 'quanto è' — 'how much is it'. The apostrophe marks the dropped 'o'. 'In tutto' means altogether or in total. The phrase is entirely standard and can also be said as 'quanto fa in tutto?' (how much does it come to altogether?).
Quanto fa in tutto?
How much does it come to altogether?
Equally common — 'fare' used for price totals.
Il totale, per favore.
The total, please.
Direct request for the total.
Quanto le devo?
How much do I owe you?
More personal — 'how much do I owe you?'
Italian prices include IVA (Imposta sul Valore Aggiunto — VAT) at various rates: 22% standard, 10% food and hospitality, 4% essential goods. Unlike the USA, the price shown is always the final price — no surprises at the till.
