Poor exchange rate maths costs travellers £288 million

More than a third of UK adults (38 per cent) are unable to convert popular currencies into sterling and are losing out on a staggering £288 million a year on holiday as a result.

Despite household budgets being squeezed, a new report by the Post Office reveals that 44 per cent of people don’t work out how much things actually cost when they are abroad and one in three people (27 per cent) go over budget when they travel.

Such is our dislike for exchange rate maths, one in five people (17 per cent) prefer holidaying in places where they understand the currency, and nearly 1.5 million people actually avoid places with unfamiliar currency because they find it too confusing and stressful to work out how much they are spending.

Despite Turkey’s growing popularity as a holiday destination, the Turkish lira topped the list of confusing currencies, 49 per cent of people were unable to convert it into sterling. And a surprising number of people struggled to convert the most popular and widely used currencies - 35 per cent did not convert US dollars accurately and 26 per cent struggled with the euro.

Rachel Riley, Countdown’s new resident maths expert said: "Working out how much things cost on holiday doesn’t have to be time consuming or confusing. To help avoid overspending, make a note of the exchange rate when you buy your currency and use my easy to remember formulae for working out some of the most popular currencies.

"It’s not always practical to carry a calculator around but most mobile phones have calculator functions, so make the most of this, particularly if buying expensive items, and work out how much you are spending before you purchase."

Sarah Munro, head of Post Office Travel Services added: "At a time where budgets are being stretched, it’s more important than ever to keep a reign on holiday spending. To make the most of your pound make sure you do your research before you go. Check out the exchange rate and do some research to find out how much things basic staples like drinks and suncream will cost when you get there.

Sarah continued: "Make sure you buy commission-free currency in advance and avoid purchasing it at airports where you won’t get the best rates and can be charged through the nose in commission; recent research shows that we waste £20 million a year by purchasing money at airports. It is also advisable not to withdraw money abroad at ATMs as you will be charged and it can be difficult to keep tabs on your spending."

Top Tips from Rachel Riley and the Post Office for budgeting on holiday:

Make a note of the exchange rate - it sounds simple but many of us change our money and then forget the rate we bought it at. Keep a note in your purse or wallet and use this as your reference when working out how much things cost. Write the equivalents for £1, £5, £10 and so on and use as a rough reference guide

Use your phone - make the most of the portable calculator that most of us have in our mobile phones, if you are struggling to work something out, you can do it quickly on your phone. For those who want something more advanced, you can buy special currency converters and calculators

Don’t pay in sterling- don’t be tempted to pay in sterling on your card or in cash as shops and restaurants can charge their own exchange rate which is unlikely to be competitive. You can also get stung by added fees of up to 4 per cent.

Bartering - in lots of popular destinations like Turkey and Morocco, bartering is part of the culture. Do your research before you go and if you’re going somewhere where bartering is acceptable, don’t be afraid to offer the merchant the price that you are willing to pay

Try a pre-paid travel card - pre-paid cards like the Post Office Travel Money Card enable you to load your card with currency when the exchange rate is good. You can then use this as you would your bank card and it helps act as your own budgeting tool to ensure you don’t spend more than you have loaded onto the card. The Travel Money Card is completely separate from your bank account too so it’s a secure way of taking money abroad.
