MTCBudget guide
Choosing a travel budget reserve alongside the modelled range
The short answer
There is no fixed reserve percentage in MTC. Keep three things separate: the modelled low-to-high range, the existing 'other' allowance inside the total, and an additional reserve you choose. You can use the upper estimate as a cautious planning scenario, then decide whether your trip needs an extra reserve; the upper estimate is not a price ceiling.
The range shows variation in the modelled costs under the stated assumptions. It is not a statistical confidence interval or a guarantee that real quotes fall inside it. A separate reserve is a planning choice, not another name for the spread.
A reserve covers events, not variance: a cancelled connection you re-book yourself, a medical visit, a change fee, a day when the weather forces you indoors and into paid activities. You size it from your own exposure — how far you are going, how tight the connections are, how refundable the bookings are — not from a percentage someone published.
How to do it
- Check whether both ends of the modelled range fit your budget. Consider the high end as a cautious scenario, then revise the inputs or obtain actual quotes if it is uncomfortable.
- Review refund deadlines, change fees and connection arrangements when choosing a reserve. More flexible terms can reduce some risks, but do not establish a universal reserve amount.
- Hold the reserve somewhere you can actually reach abroad — a card that works there, not cash in a drawer at home.
- Revise the plan when a trigger fires, not on a schedule: the dates move, a traveller is added or removed, the nights change, you switch travel style, or you receive a real quote that sits outside the modelled range.
- If you come home with the reserve unspent, that is the reserve working. It was never a forecast of spending.
Worked example
Three rows for the same trip. The third is illustrative only — the reserve is a figure chosen here to show the shape of the arithmetic, not an observed price or a recommendation:
Scenario: Georgia · departing Riyadh · November · 7 days · 2 travellers · Mid-range · SAR · flights included
| Figure | Amount |
|---|---|
| Modelled low endNot a target — the optimistic end of the range | 6,400 SAR |
| Modelled high endPlan against this figure | 10,100 SAR |
| Modelled high end + illustrative reserveAn illustrative 1,000 SAR reserve, chosen here only to show the arithmeticIllustrative only | 11,100 SAR |
- The distance between the low and high end is model uncertainty, not a reserve: 6,400–10,100 SAR.
What this example assumes
- On-the-ground costs come from the site's cost bands, whose data reference is 2026-08-23. Loading this page does not refresh that data.
- Rooms are one room per two travellers. There is no children's pricing and no age-based discount anywhere in the model.
- Airfare is modelled from the departure metro and the travel month. It is not a quote, and if you already hold a real fare you should enter it in the calculator so it replaces the modelled one.

Where this goes wrong
- Applying a flat percentage because it sounds prudent. Ten percent of a long-haul total and ten percent of a short one buy very different amounts of protection.
- Counting the "other" line as the buffer. It is inside the total and it is money you expect to spend.
- Treating the illustrative reserve in the table below as a price. It is a chosen number shown to demonstrate the method.
- Spending the reserve on the first day on an upgrade. A reserve that is spent early is just a bigger budget.
What this guide does not do
- Every figure on this page is a modelled estimate built from typical costs for the stated scenario. It is not a live fare, not a live room rate, not an offer and not a booking.
- Visa costs, travel insurance and card charges are conditional questions that depend on your passport, your insurer and your bank. This guide tells you to ask them; it does not answer them for you, and it is not legal or financial advice.
