Budgeting a Trip in Rand When You Are Paying in Foreign Currency

Last reviewed: January 27, 2026

Most travel disappointment is not about the destination. It is about a budget that was built on one number and then met a different one. If you earn in rand and spend in dollars, euros, pounds, dirhams or baht, the exchange rate is part of your trip whether you plan for it or not. Here is how to build a budget that survives contact with the real world.

Work out what is actually fixed and what is not

Split your trip into two lists. The first is everything you can pay for in rand, in advance: flights, accommodation booked and paid up front, pre-booked transfers, tours and activities, insurance. Once those are paid, the exchange rate can do what it likes and it no longer affects them. The second list is everything you will pay for once you are there: food, local transport, entry fees, tips, sim cards, the shopping you swore you would not do. That list is fully exposed to the rate.

The more of your trip that sits in the first list, the more predictable your budget is. That is the single most useful thing to know when you are deciding what to pre-book.

Read the “from” price properly

A headline price is a starting point, not a total. Before you compare two options, check what each one leaves out. Common exclusions are checked baggage, seat selection, airport and tourism taxes, resort fees charged at the hotel, transfers between the airport and your accommodation, meals other than breakfast, entry fees to attractions, and the deposit a car hire company blocks on your card.

Add those to both options and compare the totals. A more expensive package that includes transfers and baggage is often the cheaper trip. Ask us to break a quote into what is included and what you will still have to pay for, so you are comparing like with like.

Cash, travel card or bank card

Each has a role and most travellers use a combination. Some cash in local currency for arrival, small purchases, tips and places that do not take cards. A prepaid travel card loaded in the currency you will spend, which locks in a rate when you load it and keeps your main bank account separate from a card you carry around. And your normal bank card as a backup, kept somewhere different from the others.

Whatever you choose, ask your bank three questions before you leave: what does an international purchase cost, what does an overseas ATM withdrawal cost, and what is the daily limit. Withdrawal fees are usually charged per transaction, so drawing a sensible amount less often is cheaper than drawing small amounts daily. Use bank ATMs rather than standalone machines in tourist areas where you can.

Always pay in the local currency

When you tap your card abroad, the terminal will often offer to charge you in rand instead of the local currency. It looks helpful because it shows you a familiar number. It is almost always a worse deal, because the conversion is being done by the payment terminal at a rate it chooses rather than by your bank. This is sometimes labelled dynamic currency conversion. Choose the local currency every single time, and the same applies at ATMs when they offer to convert for you.

Build a daily number, then add a buffer

Instead of one big holiday figure, work out a rough daily spend for food, transport and activities, multiply it by the number of days, and convert that to rand at a rate slightly worse than today’s. If the rand strengthens, you come home with money. If it weakens, you are still fine. Then add a buffer on top for the things a budget never predicts: a medical excess, a change of plans, a taxi you did not want to take but should have.

• Convert at a deliberately conservative rate, not the best rate you saw this month.
• Budget arrival day separately. It is almost always the most expensive day of a trip.
• Keep a little local cash aside for the trip back to the airport at the end.
• Check whether your accommodation charges anything on departure that was not in the booking.
• Keep a rough running note of what you spend in the first three days. It tells you quickly whether your daily number was realistic.

Timing your money decisions

Nobody can predict the rand, and anybody who tells you they can is selling something. What you can do is reduce how much of your trip depends on it. Pay the big items early in rand, load a travel card in stages rather than all at once if you are nervous, and avoid leaving your entire spending money to be converted at the airport on the day you fly.

Tell us your total budget in rand at the start of the conversation rather than at the end. It is far easier to build a trip to a number than to trim one afterwards.
